Before explaining the solution of the present application, in order to facilitate the reader's understanding, the terms involved in the solution are explained first.

The earphone combination includes at least two wireless earphones, and a wireless connection can be established between the wireless earphones, and data transmission can be realized on the basis of the successful establishment of the wireless connection.

In this embodiment, the data transmission between the wireless earphones is described by taking the Bluetooth technology as an example. In some specific embodiments, the data transmission between the wireless earphones may also be other wireless communication technologies, such as Zigbee technology, Wi-Fi technology, General packet radio service (General packet radio service, GPRS) technology, etc.

For example, the above headset combination may be a True Wireless Stereo (TWS) headset supporting classic Bluetooth (eg, Bluetooth 5.0) technology, a TWS headset supporting Bluetooth Low Energy Audio (LE Audio) technology, and the like.

TWS technology is mainly used in audio playback equipment such as headphones and speakers. In the process of actual application, it can wirelessly separate the left and right channels to achieve a stereo effect.

TWS headset is a new smart wearable product produced by applying TWS technology to the field of Bluetooth headsets. TWS earphones are truly wireless, can be worn on both ears, intelligence, active noise reduction, and diversified interaction methods. Compared with traditional wired Bluetooth earphones, TWS earphones have the advantages of simple design, hands-free, and higher wearing convenience.

By equipped with a portable charging box, the TWS headset can be charged and stored. The charging case can also be called a headphone case.

TWS headsets that support classic Bluetooth (such as Bluetooth 5.0) technology use the primary and secondary headset transmission technology. Audio source devices such as mobile phones and tablet computers need to be wirelessly connected to the primary headset, and then the primary headset and the secondary headset. Wireless connection. Figure 1 shows an example of the working principle of a TWS headset that supports classic Bluetooth technology. The left headset in Figure 1 is the main headset, and the right headset is the secondary headset. The straight line in Figure 1 represents the wireless connection between devices.

TWS earphones supporting LE Audio technology use binaural simultaneous transmission, regardless of the main and auxiliary earphones, the left earphone and the right earphone can transmit in both directions at the same time, which can not only effectively avoid the loss of radio waves, but also reduce the delay and improve the connection stability. Better user experience. Figure 2 shows an example of the working principle of a TWS headset that supports LE Audio technology. The straight line in Figure 2 represents the wireless connection between devices. Both the left and right earphones can establish a wireless connection with the mobile phone.

LE Audio technology is based on the Bluetooth 5.2 standard, which can bring people wireless audio services with lower power consumption, lower cost, higher quality, and lower latency. At the same time, LE Audio technology also provides Coordinated Set Identification Profile (CSIP), which allows devices belonging to the same combination to achieve the purpose of coordination and synchronization when interacting with external devices. This protocol mainly describes how the external device recognizes multiple independent devices in a combination as the same combination. For multiple devices belonging to the same combination, if they are to be used with external devices at the same time, each device in the combination needs to establish an independent LE Audio connection with the external device. The identification resolution value (Set Identity Resolving Key, SIRK) is used for judgment, and the devices with the same SIRK are formed into a combination. Among them, the LE Audio connection can be understood as a Bluetooth connection based on LE Audio technology.

For ease of understanding, this embodiment takes TWS earphones and channel types that support the LE Audio technology as an example for description, but this does not constitute a limitation on the types of earphone combinations and the types of audio playback parameters.

Currently, for TWS earphones that support LE Audio technology, two earphones are usually used as a CSIP combination, and the left and right earphones are also configured to support only the left channel (that is, the value of Audio_Channel_Allocation is Front Left) and only support the right channel. Channel (that is, the value of Audio_Channel_Allocation is Front Right). Figure 3 shows an example of the interaction between the TWS headset and the mobile phone. When the user opens the headset box, the left headset and the right headset are connected, and the two headsets broadcast LE Audio. When the mobile phone scans the left headset, the mobile phone first communicates with the left headset. The headset establishes a LE Audio connection to obtain the SIRK of the left headset and the supported channel type. At this time, the left headset can interact with the mobile phone. When the mobile phone receives the LE Audio broadcast of the right earphone, it parses the SIRK of the right earphone, and judges whether the SIRK of the right earphone is the same as the SIRK of the currently connected earphone. Channel type, then when the mobile phone plays music, the left channel data can be transmitted to the left earphone, and the right channel data can be transmitted to the right earphone, which can save the Bluetooth bandwidth and decoding complexity of the left and right earphones, and can also ensure the integrity of the audio data. sex. However, when only one earphone is used to play audio (for example, the right earphone in the TWS earphone is put into the earphone box, and only the left earphone is used to listen to music), since the channel type of the left earphone is fixed, the mobile phone only transmits audio data to the left earphone. The left channel data in , due to the lack of right channel data, the audio playback effect is not good.

In order to improve the audio playback effect and bring a better sense of hearing to the user, the embodiment of the present application can dynamically update the wireless connection with the audio source device during the change of the connection state based on the change of the connection state between the earphones in the earphone combination. The audio playback parameters of the headset can be adjusted, so as to realize the adaptive update of the audio playback parameters. For example, when the left headset and the right headset change from the connected state to the disconnected state, only the left headset is connected to the mobile phone at this time. The channel type is updated from the left channel to the dual channel, which enables the mobile phone to transmit the dual channel data to the left earphone, thereby bringing a better sense of hearing to the user and improving the user experience.

It should be understood that the size of the sequence numbers of the steps in this embodiment does not mean the sequence of execution, and the execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiment of the present application.

In order to illustrate the technical solutions described in the present application, the following specific embodiments are used for description.

Referring to FIG. 4 , it is a schematic diagram of an implementation flowchart of a method for updating audio playback parameters provided by an embodiment of the present application, and the method for updating audio playback parameters is applied to a headset combination. As shown in Figure 4, the audio playback parameter update method may include the following steps:

Step 401 , based on the change of the connection state between the earphones in the earphone combination, update the audio playback parameters of the target earphone.

The change in the connection state between the earphones in the earphone combination refers to the change in the connection state between the earphones in the earphone combination. The target earphone is an earphone that maintains a wireless connection with the audio source device in the process of changing the connection state, and the target earphone is derived from the above-mentioned earphone combination. For example, the headphone combination includes a left headphone and a right headphone. During the process of changing the connection status of the left headphone and the right headphone, if the left headphone is always wirelessly connected to the audio source device, the left headphone can be determined as the target headphone.

The earphones in the earphone combination can realize data transmission between the earphones and the audio source device by establishing a wireless connection with the audio source device. The audio source device may refer to a device capable of providing audio, such as a mobile phone and a tablet computer. The aforementioned wireless connections include, but are limited to, Bluetooth connections, such as LE Audio connections.

The audio playback parameters are related to the audio playback control of the audio source device. The audio playback parameters may refer to parameters related to audio playback control of the audio source device, such as channel type, audio loudness, audio frequency, audio gain, and the like.

Headphones belonging to the same group can play the same audio in sync. For example, the left earphone and the right earphone in the TWS earphone belong to the same combination, so the left earphone and the right earphone can play the same audio synchronously.

The audio playback parameters of headphones belonging to the same combination are usually different, and on this basis, a better audio playback effect can be achieved. For example, if the audio playback parameter is the channel type, the channel type of the left earphone in the TWS earphone can be set to the left channel, and the channel type of the right earphone in the TWS earphone can be set to the right channel. By setting the channel type for the left earphone and the right earphone Different channel types to achieve stereo effect when playing audio from left and right earphones. Of course, the audio playback parameters of the headphones belonging to the same combination may also be the same, which is not limited here.

The change of the connection state between the earphones in the earphone combination includes, but is not limited to, from the connected state to the disconnected state, or from the disconnected state to the connected state, and the like. When the earphones in the earphone combination are in a connected state, data transmission can be performed between the earphones in the earphone combination, and all the earphones in the earphone combination can play audio. When the earphones in the earphone combination are disconnected, data transmission cannot be performed between the earphones in the earphone combination, and the target earphone in the earphone combination can play audio, but the candidate earphones in the earphone combination cannot play audio. The above candidate earphones refer to earphones other than the target earphones in the earphone combination.

When the connection status between the earphones in the earphone combination changes, the usage of the candidate earphones changes (for example, the candidate earphones change from being able to play audio to not being able to play audio), which may cause the audio playback effect to also change. In this case , based on the change of the connection state between the headphones, the audio playback parameters of the target headphones can be dynamically updated, and the adaptive update of the audio playback parameters can be realized, so that the audio playback effect after the connection state changes is consistent with the audio playback effect before the change, thereby improving the The audio playback effect after the connection state changes.

In an optional embodiment, the above step 401 includes:

If the connection state between the target earphone and the candidate earphone changes from the connected state to the disconnected state, the audio playback parameters of the target earphones are updated to the target audio playback parameters.

The above target audio playback parameters refer to audio playback parameters that can achieve the same audio playback effect when the headphones are in a disconnected state and audio playback effects when the headphones are in a connected state. When the connection state between the target headset and the candidate headset changes from the connected state to the disconnected state, the candidate headset changes from being able to play audio to not being able to play audio. On this basis, update the audio playback parameters of the target headset to the target The audio playback parameter can make the audio playback effect of the target earphone after the parameter update reach the effect of simultaneously playing audio by the earphones in the earphone combination.

It is understandable that the connection state between the target headset and the candidate headset changes from the connected state to the disconnected state, including that the distance between the candidate headset and the target headset is too far, resulting in the inability to transmit information between the two. Disconnected; or the candidate earphone is in the earphone box, the target earphone has been out of the earphone box, and the connection between the candidate earphone and the target earphone is disconnected; or the candidate earphone is not worn, only the target earphone is worn by the user, and the candidate earphone is connected to the target earphone. disconnection, etc.

In the case where the audio playback parameter is a channel type, the above-mentioned optional embodiments include:

If the connection state between the target earphone and the candidate earphone changes from the connected state to the disconnected state, the channel type supported by the target earphone is updated from the corresponding monophonic to the dual-channel.

Wherein, after the channel type supported by the target earphone is updated, the channel type supported by the target earphone is dual channel, and the dual channel includes the mono channel supported before the target earphone is updated and the mono channel supported by the candidate earphone. For example, the target earphone supports the left channel, and the candidate earphone supports the right channel. When the connection state between the target earphone and the candidate earphone changes from the connected state to the disconnected state, the channel type supported by the target earphone can be changed from the left channel. It is updated to include the left channel and the right channel, so that the target earphone can play the two-channel data (ie, the left channel data and the right channel data) to realize the stereo effect.

In an optional embodiment, the above step 401 includes:

If the connection state between the target earphone and the candidate earphone changes from the disconnected state to the connected state, the audio playback parameters of the target earphone are updated to the default audio playback parameters of the target earphone.

It can be understood that the connection state between the target headset and the candidate headset changes from disconnected to connected, including that the distance between the candidate headset and the target headset is close, and information transmission can be achieved between the two, and the candidate headset and the target The earphone is connected; or both the candidate earphone and the target earphone are out of the earphone box, and the candidate earphone is connected with the target earphone; or both the candidate earphone and the target earphone are worn by the user, and the candidate earphone and the target earphone are connected.

When the connection state between the target earphone and the candidate earphone changes from the disconnected state to the connected state, the candidate earphone changes from unable to play audio to playable audio. On this basis, the audio playback parameters of the target earphone are updated to the default. The audio playback parameter enables the headphones in the headphone combination to play the same audio synchronously. Wherein, the default audio playback parameter may refer to the initial value of the target earphone before updating. For example, when the target earphone and the candidate earphone are respectively the left earphone and the right earphone in the same TWS earphone, the default channel type of the left earphone may be the left channel, and the default channel type of the right earphone may be the right channel.

In the case where the audio playback parameter is a channel type, the above-mentioned optional embodiments include:

If the connection state between the target earphone and the candidate earphone changes from the disconnected state to the connected state, the channel type supported by the target earphone is updated from dual channel to corresponding monophonic channel.

When the connection state between the target headset and the candidate headset changes from disconnected to connected, both the target headset and the candidate headset can play audio, by updating the channel type supported by the target headset from binaural to corresponding Mono, so that both the target earphone and the candidate earphone can play their corresponding mono data, so that the stereo effect can be achieved through the target earphone and the candidate earphone. For example, the default target earphone supports the left channel, and the candidate earphone supports the right channel. When the connection state between the target earphone and the candidate earphone changes from disconnected to connected, change the channel type supported by the target earphone from dual-channel The channel is updated to the default left channel, so that the target earphone can play the left channel data, and the candidate earphone can play the right channel data, so as to realize the stereo effect through the target earphone and the candidate earphone.

In this embodiment, audio loudness, audio frequency, audio gain, etc. may also be used as examples to describe the updating process of audio playback parameters when the connection state between headphones changes from disconnected state to connected state. For example, when the audio playback parameter is audio loudness, when the connection state between the target earphone and the candidate earphone changes from the disconnected state to the connected state, the audio loudness of the target earphone can be updated from 60 decibels to 50 decibels. The audio loudness of the earphone is also 50 dB, so that the audio playback effect of using the target earphone and the candidate earphone at the same time is consistent with the audio playback effect of using the target earphone alone. When the audio playback parameter is the audio frequency, when the connection state between the target headset and the candidate headset changes from disconnected to connected, the audio frequency of the target headset can be updated from 30 to 500 Hz to 150 to 500 Hz, and the candidate headset The audio frequency is 30-150 Hz, so that the audio playback effect of using the target earphone and the candidate earphone at the same time is consistent with the audio playback effect of using the target earphone alone. When the audio playback parameter is the audio gain, when the connection state between the target headset and the candidate headset changes from disconnected to connected, the audio gain of the target headset can be updated from 5db to 3db, and the audio gain of the candidate headset is 2db , so that the audio playback effect of using the target headset and the candidate headset at the same time is consistent with the audio playback effect of using the target headset alone.

In an optional embodiment, under the condition that the target earphone and the candidate earphone are in a disconnected state, first broadcast information is sent to the target earphone, and the first broadcast information indicates that the target earphone feeds back a connection request; in response to the connection of the target earphone request, establish a wireless connection between the target earphone and the candidate earphone, and determine that the connection state between the target earphone and the candidate earphone changes from a disconnected state to a connected state.

When the target headset and the candidate headset are in a disconnected state, a wireless connection is not established between the target headset and the candidate headset, and the candidate headset can establish a connection with the target headset based on the received connection request by sending the first broadcast information to the target headset. The wireless connection between the target earphones and the candidate earphones realizes data transmission. The first broadcast information refers to broadcast information sent by the candidate earphone to the target earphone. The connection request of the target headset instructs the candidate headset to establish a wireless connection with the target headset.

For some earphone combinations (such as TWS earphones based on LE Audio technology), each earphone included can establish a wireless connection with the audio source device (that is, both the target earphone and the candidate earphone in this application can establish a wireless connection with the audio source device. ), enabling data transfer between each earphone and the audio source device. In the case of establishing a wireless connection between the audio source device and the candidate earphone, the candidate earphone can implement audio playback control on the audio source device through the following two optional embodiments.

An optional embodiment is: sending the audio playback parameters of the candidate earphones to the audio source device, receiving the adjusted audio data sent by the audio source device, and the adjusted audio data is adjusted according to the audio playback parameters of the candidate earphones. formed audio data.

Optionally, the audio source device that establishes the connection with the candidate earphone sends a parameter query command to query the audio playback parameters of the candidate earphone; or, after the candidate earphone establishes the connection with the audio source device, it actively sends the audio playback to the audio source device. parameter information.

It can be understood that the candidate headset sends its own audio playback parameters to the audio source device. After receiving the audio playback parameters of the candidate headset, the audio source device can adjust the audio data based on the audio playback parameters of the candidate headset, and send the adjusted audio data to the candidate headset. the audio data, so as to realize the audio playback control of the audio source device.

Taking the channel type as an example, if the channel type of the candidate earphone is monaural, the audio source device can adjust the audio data sent to the candidate earphone to the monaural data corresponding to the monaural; If the channel type is binaural, the audio data sent by the audio source device to the candidate earphone is adjusted to the binaural data corresponding to the binaural.

Another optional embodiment is: adjusting the audio data from the audio source device based on the audio playback parameters of the candidate earphones.

The audio source device can send audio data to the candidate earphone. After the candidate earphone receives the audio data from the audio source device, it can adjust the received audio data based on its own audio playback parameters, so as to realize the audio data of the audio source device. Playback controls.

Taking the channel type as an example, if the channel type of the candidate earphone is monaural, the candidate earphone can adjust the audio data sent by the audio source device to the monaural data corresponding to the monaural channel; If the channel type is binaural, the candidate earphone can adjust the audio data sent by the audio source device to the binaural data corresponding to the binaural.

In an optional embodiment, the candidate earphone may establish a wireless connection with the audio source device in the following manner:

sending second broadcast information to the audio source device, where the second broadcast information instructs the audio source device to feed back a connection request;

In response to the connection request from the audio source device, a wireless connection between the audio source device and the candidate headset is established.

By sending the second broadcast information to the audio source device, the candidate earphone can establish a wireless connection with the audio source device based on the received connection request, so as to realize data transmission between the audio source device and the candidate earphone. The second broadcast information refers to broadcast information sent by the candidate earphone to the audio source device. The connection request of the audio source device instructs the candidate headset to establish a wireless connection with the audio source device.

Optionally, after receiving the second broadcast information, the audio source device can also analyze whether the candidate earphone and the target earphone belong to the same CSIP combination, and if the candidate earphone and the target earphone belong to the same CSIP combination, the connection request is fed back to the candidate earphone, so that the The candidate earphone and the target earphone achieve the purpose of coordination and synchronization when interacting with the audio source device.

The above-mentioned second broadcast information may include the SIRK of the candidate earphone. The audio source device can analyze whether the candidate earphone and the target earphone belong to the same CSIP combination based on the SIRK of the candidate earphone and the SIRK of the target earphone. It can be understood that if the SIRK of the candidate earphone is the same as that of the target earphone, it can be determined that the candidate earphone and the target earphone belong to the same CSIP combination; if the SIRK of the candidate earphone and the SIRK of the target earphone are different, it can be determined that the candidate earphone and the target earphone belong to the same CSIP combination. The headsets do not belong to the same CSIP group.

After updating the audio playback parameters of the target headset, the target headset can adjust the playback audio of the audio source device through the following two optional embodiments.

An optional embodiment is: adjusting the audio data from the audio source device based on the updated audio playback parameters.

The audio source device can send audio data to the target earphone. After receiving the audio data from the audio source device, the target earphone can adjust the received audio data based on the updated audio playback parameters, so as to realize the audio data of the audio source device. Audio playback controls.

For example, the target headset in the TWS headset can transmit data with the mobile phone, the mobile phone sends audio data to the target headset, the target headset adjusts the received audio data based on the updated audio playback parameters, and can be based on the target headset and candidate headsets. The change of the connection state between them can adaptively adjust the audio data to improve the user experience.

In the case where the audio playback parameter is the channel type, for the target earphone in the TWS headset, if the updated channel type is two-channel, then by acquiring the corresponding two-channel data and playing the two-channel data, The loss of channel data can be avoided, so that the stereo effect can be realized based on the target earphone; if the updated channel type is mono, by obtaining the corresponding mono data, the target earphone and the candidate earphone can play the same channel as their own channel at the same time. Mono data corresponding to the type to achieve stereo effect.

For example, if the updated channel type of the target earphone is the left channel, the target earphone obtains the left channel data from the received audio data, the candidate earphone obtains the right channel data from the audio data forwarded by the target earphone, and the target earphone obtains the right channel data from the audio data forwarded by the target earphone. While playing the data of the left channel, the candidate earphone plays the data of the right channel, so as to realize the stereo effect.

Another optional embodiment is: sending the updated audio playback parameters to the audio source device, where the updated audio playback parameters are used to adjust the audio data sent by the audio source device to the target earphone.

The target headset sends the updated audio playback parameters to the audio source device. After receiving the updated audio playback parameters, the audio source device can adjust the audio data based on the updated audio playback parameters, and send the adjusted audio data to the target headset. Thereby, the audio playback control of the audio source device is realized.

For example, for a TWS earphone based on LE Audio technology, both earphones in the TWS earphone can transmit data with the mobile phone. Therefore, in this case, the mobile phone can first adjust the data sent to the two earphones based on the updated audio playback parameters. The audio data makes the two headphones work together to achieve a stereo effect.

In the case where the audio playback parameter is the channel type, if the updated channel type is two-channel, the first channel information is sent to the audio source device, and the first channel information is used to send the audio source device to the target earphone. The sent audio data is adjusted to the two-channel data corresponding to the two-channel;

Or, if the updated channel type is mono, the second channel information is sent to the audio source device, and the second channel information is used to adjust the audio data sent by the audio source device to the target earphone to correspond to mono. mono data.

It can be understood that the first channel information may include a dual channel identifier, and the dual channel identifier includes a mono channel identifier supported by the target earphone and the candidate earphone respectively. The second channel information may include the updated monophonic identification. For example, the monaural identifiers supported by the target earphone and the candidate earphone are Front Left (the identifier of the left channel) and FrontRight (the identifier of the right channel), then the first channel information may include Front Left and Front Right; if the earphone The updated channel type is left channel, then the second channel information may include Front Left.

If the updated channel type is two-channel, by sending the first channel information to the audio source device, the audio source device can feed back the corresponding two-channel data, and the target earphone plays the received two-channel data, The channel data loss can be avoided, so as to realize the stereo effect; if the updated channel type is mono, then by sending the second channel information to the audio source device, the audio source device can feedback the corresponding mono to the target earphone. The target earphone and the candidate earphone can play the mono data corresponding to their own channel type at the same time to realize the stereo effect.

For example, taking the target earphone and candidate earphone in a TWS earphone supporting LE Audio technology as an example, if the updated channel type of the target earphone is the left channel, the target earphone can send the first channel information to the audio source device to Make the audio source device feed back the two-channel data, and the target earphone will play the two-channel data, which can avoid the loss of the right channel data, so as to realize the stereo effect; if the updated channel type of the target earphone is the left channel, the audio source The device sends the second channel information, so that the audio source device feeds back the left channel data to the target earphone and the right channel data to the candidate earphone. While the target earphone is playing the left channel data, the candidate earphone plays the right channel data, thereby Stereo effect can be achieved.

In an optional embodiment, the updated audio playback parameters are sent to the audio source device, including:

If no audio data is transmitted between the target earphone and the audio source device, it is determined that the target earphone is in a non-service state, and the updated audio playback parameters are sent to the audio source device.

When the target headset is in a non-service state, the updated audio playback parameters are sent to the audio source device, which can reduce the impact of parameter transmission on the service of the target headset, and complete the parameter transmission without the user feeling it.

In an optional embodiment, it can be determined whether the target earphone is in a non-service state by detecting whether audio data is transmitted between the target earphone and the audio source device; if no audio data is transmitted between the target earphone and the audio source data, the target earphone is determined. The headset is in a non-service state, and if audio data is transmitted between the target headset and the audio source data, it is determined that the target headset is in a service state.

It can be understood that when the audio source device pauses the music, it stops transmitting audio data to the target earphone, that is, no audio data is transmitted between the target earphone and the audio source device, and the target earphone also pauses the music. Service state, in this state, the target headset sends the updated audio playback parameters to the audio source device. When the audio source device plays music, the audio data is transmitted to the target earphone, that is, the audio data is transmitted between the target earphone and the audio source device, and the target earphone also plays music. In this case, the target earphone is in a business state.

In another optional embodiment, sending the updated audio playback parameters to the audio source device includes:

In response to the parameter query instruction of the audio source device, the updated audio playback parameters are sent to the audio source device.

The parameter query instruction instructs the target headset to send the updated audio playback parameters to the audio source device. The parameter query command is sent by the audio source device under the condition that the connection state with the candidate earphone changes.

Optionally, when the connection status between the target headset and the candidate headset changes, the connection status between the audio source device and the candidate headset also changes. Therefore, when the connection status between the audio source device and the candidate headset changes, the target headset is based on the The connection state of the candidate headset changes to update its own audio playback parameters. In this case, the audio source device can actively send a parameter query command to the target headset to obtain the updated audio playback parameters of the target headset.

Optionally, in the case where the connection status between the target headset and the candidate headset changes, such as the target headset establishes a connection with the candidate headset, and the audio source device also establishes a connection with the candidate headset, the candidate headset can feedback that the target headset has been connected to the audio source. The device establishes a connection. Based on this, the target headset can actively send its own audio playback parameters to the audio source device, so that the audio source device can adjust its audio output scheme and output audio that is more in line with the audio playback parameters of the target headset.

In the embodiment of the present application, based on the change of the connection state between the earphones in the earphone combination, the audio playback parameters of the earphones that are wirelessly connected to the audio source device during the process of the above-mentioned connection state change can be dynamically updated, thereby realizing the automatic adjustment of the audio playback parameters. Adapt to updates and improve user experience.

FIG. 5 is a schematic flowchart of an implementation of an audio data adjustment method provided by an embodiment of the present application, where the audio data adjustment method is applied to an audio source device. As shown in Figure 5, the audio data adjustment method may include the following steps:

Step 501: Receive updated audio playback parameters from the target earphone, where the updated audio playback parameters are obtained based on changes in the connection state between the earphones in the earphone combination.

The target earphone is an earphone that maintains a wireless connection with the audio source device in the process of changing the connection state.

For the solution of obtaining the updated audio playback parameters based on the change of the connection state between the earphones in the earphone combination, reference may be made to the above method embodiments, which will not be repeated here.

After the target headset obtains the updated audio playback parameters, it can actively send the updated audio playback parameters to the audio source device, or it can send the updated audio to the audio source device when it receives a parameter query command from the audio source device. The playback parameters are not limited here. The parameter query instruction instructs the target headset to send the updated audio playback parameters to the audio source device.

In an optional embodiment, if the connection state with the candidate earphone changes, a parameter query instruction is sent to the target earphone.

When the connection status between the target headset and the candidate headset changes, the connection status between the audio source device and the candidate headset also changes. Therefore, when the connection status between the audio source device and the candidate headset changes, the target headset has already changed based on the connection status with the candidate headset. The connection state changes to update its own audio playback parameters. In this case, the audio source device can actively send a parameter query command to the target headset to obtain the updated audio playback parameters of the target headset.

In an optional embodiment, if the connection state with the candidate earphone changes, a parameter query instruction is sent to the target earphone, including:

If the connection state with the candidate earphone changes, the parameter query instruction is sent to the target earphone when it is in the no-service state.

The audio source device can only play audio based on the updated audio playback parameters when the audio source device is in a non-service state. Therefore, when the audio source device is in a non-service state, a parameter query command can be sent to the target headset, so as to obtain the updated audio playback parameters, which is convenient for the next time. When playing audio, it can be played based on the updated audio playing parameters.

In an optional embodiment, by detecting whether audio data is transmitted between the audio source device and the earphone in the earphone combination, it can be determined whether the audio source device and the earphone in the earphone combination are in a no-service state, if the audio source device and the earphone in the earphone combination are in a no-service state If no audio data is transmitted between the earphones in the earphone combination, it is determined that the audio source device is in a non-service state. If audio data is transmitted between the audio source device and the earphones in the earphone combination, it is determined that the audio source device is in a service state.

In an optional embodiment, when receiving the second broadcast information from the candidate headset, the audio source device may feed back a connection request to the candidate headset, where the connection request instructs the candidate headset to establish a wireless connection with the audio source device.

Wherein, the second broadcast information may include the SIRK of the candidate earphone.

When the audio source device establishes a wireless connection with the target earphone, if it receives the second broadcast information from the candidate earphone, it can compare the SIRK of the target earphone and the SIRK of the candidate earphone. If the SIRK of the target earphone is the same as the SIRK of the candidate earphone, Then it is determined that the target earphone and the candidate earphone belong to the same CSIP combination, and the audio source device can send a connection request to the candidate earphone to establish a wireless connection with the candidate earphone, so as to realize the switch from one ear to both ears, that is, to switch from one earphone to the other. If the SIRK of the target earphone is different from that of the candidate earphone, it is determined that the target earphone and the candidate earphone do not belong to the same CSIP combination, and the audio source device does not establish a wireless connection with the candidate earphone and still maintains a single earphone. use.

In an optional embodiment, after establishing the wireless connection with the candidate headset, the method further includes:

Get the audio playback parameters of the candidate headset;

Based on the audio playback parameters of the candidate earphones, the audio data is adjusted, and the adjusted audio data is sent to the candidate earphones.

The adjusted audio data is audio data corresponding to the audio playback parameters of the candidate earphones. For example, if the audio playback parameter of the candidate earphone is the right channel, the adjusted audio data is the right channel data, and the audio source device sends the right channel data to the candidate earphone.

Step 502: Adjust the audio data sent to the target earphone based on the updated audio playback parameters.

Through step 502, the audio playback control of the audio source device can be realized.

In an optional embodiment, when the audio playback parameter is a channel type, the above step 502 includes:

If the updated audio playback parameter is mono, send the corresponding mono data to the target earphone;

Or, if the updated audio playback parameter is two-channel, the corresponding two-channel data is sent to the target earphone.

If the updated audio playback parameter is monaural, it means that it has been switched from monaural to binaural. In this case, the audio source device sends the corresponding monaural data to the target earphone and the candidate earphone. Play audio with candidate headphones and achieve stereo effect. If the updated audio playback parameter is two-channel, it means that it has been switched from binaural to mono-aural. In this case, the audio source device sends two-channel data to the target earphone, so that one earphone can be used to achieve stereo effect.

In the embodiment of the present application, by receiving the updated audio playback parameters from the target earphone, the audio data sent to the target earphone can be adjusted based on the updated audio playback parameters, thereby realizing the adaptive adjustment of the audio data and improving the user experience. sense.

The situation where the target headset needs to update the audio playback parameters is mainly divided into two scenarios. The left headset in the TWS headset supporting the LE Audio technology is used as the target headset and the right headset is used as the candidate headset as an example for description.

As shown in Figure 6, the first scenario is when the TWS headset is switched from two headsets to use only one headset:

Open the earphone box, the left earphone and the right earphone establish a wireless connection, the left earphone and the right earphone broadcast LE Audio respectively, the user can turn on the scanning function on the mobile phone, if the mobile phone receives the broadcast 1 from the left earphone, it is determined that the mobile phone scans to the left earphone Headphone, the user can click connect on the mobile phone to establish a LE Audio connection between the mobile phone and the left earphone, and obtain the SIRK of the left earphone and the supported channel type Front Left. When the mobile phone receives the broadcast 2 from the right earphone, it can be based on The SIRK of the left earphone and the SIRK of the right earphone analyze whether the right earphone and the left earphone belong to the same CSIP combination. If the right earphone and the left earphone belong to the same CSIP combination, the mobile phone initiates a LE Audio connection to the right earphone to establish a LEAudio connection with the right earphone. After the connection is successfully established, get the channel type Front Right supported by the right earphone. If the user puts the right earphone into the earphone box and closes the cover, in this case, the connection state between the left earphone and the right earphone changes from the connected state to the disconnected state, and the left earphone updates the channel type supported by itself, from only Support Front Left update to support FrontLeft and Front Right at the same time, and send the updated channel types Front Left and FrontRight to the mobile phone when there is no service state, after the mobile phone receives the updated channel types Front Left and Front Right of the left earphone, If music is played, two-channel data is sent to the left earphone, and the left earphone plays music based on the two-channel data, which can achieve a stereo effect.

As shown in Figure 7, the second scenario is when the TWS headset is switched from using one headset to using two headsets at the same time:

When the connection between the left earphone and the right earphone is disconnected (for example, the left earphone is taken out of the earphone box for use, but the right earphone is not taken out and the earphone box is closed), the left earphone broadcasts LE Audio, and the user can turn on the mobile phone If the mobile phone receives the broadcast 1 from the left earphone, it is determined that the mobile phone scans the left earphone, and the user can click connect on the mobile phone to make the mobile phone establish the LE Audio connection with the left earphone, and obtain the SIRK and Supported channel types. The left earphone returns the supported channel types Front Left and Front Right to the mobile phone when it is in a non-service state. When the mobile phone is playing music, it sends two-channel data to the left earphone, and plays based on the two-channel data. Music, in this case, if the user takes out the right earphone from the earphone box and uses it, the connection state between the left earphone and the right earphone changes from disconnected to connected, the right earphone broadcasts LE Audio, and the mobile phone is in When the broadcast 2 from the right earphone is received, it can be analyzed whether the right earphone and the left earphone belong to the same CSIP combination based on the SIRK of the left earphone and the SIRK of the right earphone. If the right earphone and the left earphone belong to the same CSIP combination, the mobile phone initiates the right earphone LE Audio connection to establish a LEAudio connection with the right earphone. After the connection is successfully established, the channel type Front Right supported by the right earphone is obtained, the right channel data is sent to the right earphone, and the right earphone plays music based on the right channel data; When the music is paused (for example, the user clicks the music pause button on the mobile phone), the mobile phone stops sending audio data to the left earphone and the right earphone, and both the left earphone and the right earphone pause the music; If a wireless connection is established, the left earphone can update the channel type it supports, from Front Left and Front Right to Front Left, and when there is no service, it sends the updated channel type Front Left to the phone, and the phone continues When playing music, the left channel data is sent to the left earphone, and the right channel data is sent to the right earphone. The left earphone and the right earphone play music based on the channel data received by themselves, which can achieve a stereo effect.
