The second wireless communication chip is connected with the first control circuit and is also used for being connected with the mobile terminal so as to directly interact audio information with the mobile terminal.

As described in detail below.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a speaker device according to an embodiment of the present invention.
In one embodiment, the speaker device 1 includes a first control circuit 11 and a first wireless communication chip 12. The first wireless communication chip 12 is connected to the first control circuit 11, and the first control circuit 11 is further configured to be connected to a relay device, so as to perform audio information interaction with the mobile terminal through the relay device. The speaker device 1 further comprises a second wireless communication chip 13, the second wireless communication chip 13 is connected to the first control circuit 11, and the second wireless communication chip 13 is further used for connecting to a mobile terminal, so as to directly perform audio information interaction with the mobile terminal. The speaker device 1 may be an earphone or the like, and specifically includes an in-ear earphone, a headphone, a neck-worn earphone, and the like.
The first control circuit 11 is configured to control the first wireless communication chip 12 and/or the second wireless communication chip 13 to perform audio information interaction with the mobile terminal, and specifically includes:
when the first control circuit 11 controls the first wireless communication chip 12 and the mobile terminal to perform audio information interaction, the relay device serves as a medium for audio information interaction between the speaker device 1 and the mobile terminal, and audio information output by the speaker device 1 and the mobile terminal passes through the relay device and then is transmitted to a corresponding receiver.
Since the delay of the audio information transmission by the first wireless communication chip 12 is lower than the delay of the audio information transmission by the second wireless communication chip 13, the first wireless communication chip 12 is applied to the transmission of audio information requiring low transmission delay, such as the transmission of the audio of a game with high real-time performance. For example, when the speaker device 1, the relay device and the mobile terminal are applied to transmit game audio, specifically, the relay device may be a game pad or the like for controlling the mobile terminal to perform game experience, the speaker device 1 may be an earphone or the like, and the mobile terminal may be a smartphone or the like. The relay device is connected to the first wireless communication chip 12 of the loudspeaking device 1 and the mobile terminal, respectively, wherein the relay device and the first wireless communication chip 12 can be in wireless communication connection, and the relay device and the mobile terminal can be in wired connection. The game audio (including the background music of the game and the voice communication among the players, etc.) output by the mobile terminal passes through the transfer device, then reaches the first wireless communication chip 12 of the loudspeaking device 1, and is received by the user wearing the loudspeaking device 1; the audio information (in a form of voice communication with other players) input by the user to the first wireless communication chip 12 of the speaker device 1 is output to the relay device through the speaker device 1, and then reaches the mobile terminal, so as to be received by a corresponding receiving party (for example, other players except the user, etc.).
When the first control circuit 11 controls the second wireless communication chip 13 to perform audio information interaction with the mobile terminal, the audio information output by the speaker device 1 and the mobile terminal is directly transmitted to a corresponding receiver, that is, the second wireless communication chip 13 of the speaker device 1 directly performs audio information interaction with the mobile terminal.
The first wireless communication chip 12 of the speaker device 1 cannot directly interact with the mobile terminal for audio information, which will be explained below. Therefore, when the first wireless communication chip 12 is applied to the transmission of audio information requiring low transmission delay (requiring high transmission delay), the relay device and the mobile terminal need to be collocated for audio information interaction. When the speaker device 1 is applied to transmission of general audio information (the requirement for transmission delay is low), the speaker device 1 can directly perform audio information interaction with the mobile terminal through the second wireless communication chip 13, without using a relay device, so that devices required for audio information interaction can be reduced, and convenience of audio information interaction between the speaker device 1 and the mobile terminal is improved.
It should be noted that the speaker device 1 provided in this embodiment has the first wireless communication chip 12 and the second wireless communication chip 13, and can select an appropriate wireless communication chip according to the requirement of the audio information to be transmitted for the transmission delay. Specifically, when the audio information to be transmitted requires low transmission delay, the first control circuit 11 may control the first wireless communication chip 12 to perform audio information interaction, and meanwhile, a transfer device needs to be collocated; when the requirement of the audio information to be transmitted on transmission delay is low, the first control circuit 11 can control the second wireless communication chip 13 to perform audio information interaction, so that the use of a transfer device can be avoided, and the convenience of audio information interaction between the loudspeaker device 1 and the mobile terminal is improved.
Of course, the first control circuit 11 may also control the first wireless communication chip 12 and the second wireless communication chip 13 to perform audio information interaction with the mobile terminal together, so as to transmit audio information with different transmission delay requirements, respectively. Specifically, the first wireless communication chip 12 and the mobile terminal perform interaction of first audio information, and the second wireless communication chip 13 and the mobile terminal perform interaction of second audio information. Wherein the required transmission delay of the first audio information is lower than the required transmission delay of the second audio information. Therefore, the workload of the first wireless communication chip 12 or the second wireless communication chip 13 can be prevented from being increased due to the fact that the first wireless communication chip 12 or the second wireless communication chip 13 is independently used for audio information interaction; and the problem that the requirement of the first audio information on transmission delay cannot be met because the audio information interaction is carried out by independently depending on the second wireless communication chip 13 can be avoided.
As can be seen from the above, in the loudspeaking device provided by the present invention, the first wireless communication chip and the second wireless communication chip implement audio information interaction between the loudspeaking device and the mobile terminal in a wireless communication manner, thereby avoiding adverse effects on the convenience of use of the user caused by the wired loudspeaking device, and improving the convenience of use of the loudspeaking device. And the time delay of the audio information transmission of the first wireless communication chip is lower than the time delay of the audio information transmission of the second wireless communication chip, so that compared with the second wireless communication chip, the audio information transmission of the first wireless communication chip can reduce the time delay of the audio information transmission between the loudspeaker device and the mobile terminal. And according to the requirement of the audio information to be transmitted on transmission delay, a proper wireless communication chip can be selected for audio information interaction.
In one embodiment, the first wireless communication chip 12 is a 2.4GHz communication chip, and the second wireless communication chip 13 is a bluetooth communication chip. The second wireless communication chip 13 is based on a bluetooth communication protocol, which is unified in the industry, and manufacturers cannot modify the bluetooth communication protocol according to requirements. The first wireless communication chip 12 is based on a 2.4GHz wireless audio private protocol, and the 2.4GHz wireless audio private protocol is based on a wireless communication technology with a working frequency band of 2402-2480 MHz, which allows a manufacturer to modify the protocol, and specifically, the wireless communication mode based on the 2.4GHz wireless audio private protocol has a lower transmission delay than the wireless communication mode based on the existing bluetooth communication protocol by adjusting the size of a data packet used for communication, a data verification mode, selecting a proper signal transceiver, and the like.
For the audio information requiring low transmission delay, the delay of transmitting the audio information in the wireless communication mode based on the existing Bluetooth communication protocol cannot meet the requirement, and the delay of transmitting the audio information in the wireless communication mode based on the 2.4GHz wireless audio private protocol can well meet the requirement.
Certainly, the first wireless communication chip 12 may also be a 5.8GHz communication chip, and the working frequency band of the 5.8GHz wireless audio private protocol based on the first wireless communication chip 12 is higher than the working frequency band of the 2.4GHz wireless audio private protocol. The 5.8GHz wireless audio private protocol also allows manufacturers to modify the protocol, and the wireless communication mode based on the 5.8GHz wireless audio private protocol has lower transmission delay than the wireless communication mode based on the existing bluetooth communication protocol by adjusting the size of the data packet used for communication, checking the data, and selecting a suitable signal transceiver.
For example, taking the first wireless communication chip 12 as a 2.4GHz communication chip and the second wireless communication chip 13 as a bluetooth communication chip as an example, when audio information (such as game audio) requiring low transmission delay needs to be transmitted between the speaker device 1 and the mobile terminal, the speaker device 1 and the relay device perform audio information interaction based on a 2.4GHz wireless audio private protocol, and further perform audio information interaction with the mobile terminal; when the requirement of the audio information transmitted between the speaker device 1 and the mobile terminal on transmission delay is low, the speaker device 1 and the mobile terminal directly perform audio information interaction through bluetooth, and at this time, the speaker device 1 is a bluetooth device, for example, a bluetooth headset.
In an embodiment, the first control circuit 11 may be a chip integrated with a logic operation circuit, and is used as a main control portion of the loudspeaker apparatus 1 for controlling the components of the loudspeaker apparatus 1 to work in coordination. The figure shows the case where the second wireless communication chip 13 is integrated with the first control circuit 11. Of course, in other embodiments of the present invention, the second wireless communication chip 13 may also be independent of the first control circuit 11, and is not limited herein. Moreover, the first wireless communication chip 12 and/or the second wireless communication chip 13 may have not only the function of transmitting and receiving signals but also the function of encoding and decoding; alternatively, the first wireless communication chip 12 and/or the second wireless communication chip 13 may only have the function of transmitting and receiving signals, and the function of encoding and decoding is implemented by the first control circuit 11, which is not limited herein.
In an embodiment, the speaker device 1 further includes a mode switch 14, the mode switch 14 is connected to the first control circuit 11, and the mode switch 14 is configured to instruct the first control circuit 11 to control the first wireless communication chip 12 and/or the second wireless communication chip 13 to perform audio information interaction, so as to switch a transmission mode of the audio information of the speaker device 1.
The mode switch 14 is a medium for the speaker apparatus 1 to provide the user with switching the transmission mode of the audio information of the speaker apparatus 1. By operating the mode switch 14, the user enables the loudspeaker device 1 to perform audio information interaction through the first wireless communication chip 12, or perform audio information interaction through the second wireless communication chip 13, or perform audio information interaction through both the first wireless communication chip 12 and the second wireless communication chip 13.
Specifically, when the user needs the audio output device 1 to be applied to transmission of audio information requiring low transmission delay, such as game audio, the user operates the mode switch 14, so that the audio output device 1 is switched to perform audio information interaction through the first wireless communication chip 12; when the user needs the audio output device 1 to be applied to the transmission of audio information with low requirement on transmission delay, for example, transmitting a call voice, the user operates the mode switch 14, so that the audio output device 1 is switched to perform audio information interaction through the second wireless communication chip 13; or the user needs the loud speaker device 1 to be applied to jointly transmit the audio information with higher transmission delay requirement and lower transmission delay requirement, the user operates the mode switch 14, so that the loud speaker device 1 is switched to jointly perform audio information interaction through the first wireless communication chip 12 and the second wireless communication chip 13, for example, the user simultaneously answers the call in the game process, and interacts the audio information with higher transmission delay requirement through the first wireless communication chip 12, and interacts the audio information with lower transmission delay requirement through the second wireless communication chip 13.
In one embodiment, the speaker device 1 further includes an audio output circuit 15, and the audio output circuit 15 is configured to output audio information from the relay device or the mobile terminal to the user. The audio output circuit 15 may include a speaker such as a speaker, which may be a moving-coil speaker, a moving-iron speaker, a coil-iron speaker, etc., but is not limited thereto.
Normally, only one set of audio output circuits 15 is provided in the speaker device 1, and therefore the first wireless communication chip 12 and the second wireless communication chip 13 share the audio output circuits 15. Meanwhile, the speaker device 1 further includes a first switch 151, and the first switch 151 is configured to selectively turn on the first wireless communication chip 12 and the audio output circuit 15 and/or turn on the second wireless communication chip 13 and the audio output circuit 15, so as to output the audio information transmitted by the first wireless communication chip 12 and the second wireless communication chip 13.
Specifically, the control terminal 1511 of the first switch 151 is connected to the first control circuit 11, the output terminal 1512 of the first switch 151 is connected to the audio output circuit 15, the first input terminal 1513 of the first switch 151 is connected to the first wireless communication chip 12, and the second input terminal 1514 of the first switch 151 is connected to the second wireless communication chip 13.
When the mode switch 14 instructs the first control circuit 11 to control the first wireless communication chip 12 to perform audio information interaction, the first control circuit 11 controls the first input terminal 1513 of the first switch 151 and the output terminal 1512 of the first switch 151 to be turned on through the first switch 151, i.e. the first wireless communication chip 12 and the audio output circuit 15 are turned on; when the mode switch 14 instructs the first control circuit 11 to control the second wireless communication chip 13 to perform audio information interaction, the first control circuit 11 controls the second input 1514 of the first switch 151 and the output 1512 of the first switch 151 to be turned on through the first switch 151, that is, the second wireless communication chip 13 and the audio output circuit 15 are turned on.
It should be noted that the first switch 151 may be a single-pole double-throw switch, etc., and the first switch 151 cannot simultaneously turn on the first wireless communication chip 12 and the audio output circuit 15, and the second wireless communication chip 13 and the audio output circuit 15, and if the first switch 151 is simultaneously turned on, the normal transmission of the audio information is necessarily affected. Therefore, the output of the audio information transmitted by the first wireless communication chip 12 and the second wireless communication chip 13 is time-division alternated, that is, the conduction of the first wireless communication chip 12 and the audio output circuit 15 and the conduction of the second wireless communication chip 13 and the audio output circuit 15 are time-division alternated. When the mode switch 14 instructs the first control circuit 11 to control the first wireless communication chip 12 and the second wireless communication chip 13 to perform audio information interaction together, the conduction of the first wireless communication chip 12 and the audio output circuit 15 and the conduction of the second wireless communication chip 13 and the audio output circuit 15 are performed alternately in a time-sharing manner, so that the audio information transmitted by the first wireless communication chip 12 and the second wireless communication chip 13 can be output through the audio output circuit 15. Moreover, because the first wireless communication chip 12 and the audio output circuit 15, and the second wireless communication chip 13 and the audio output circuit 15 are alternately turned on at a high frequency in a time-sharing manner, the user cannot perceive the time delay caused by outputting the audio information transmitted by the first wireless communication chip 12 and the second wireless communication chip 13 at a time-sharing manner, and the normal use experience of the user is not influenced.
In an embodiment, the speaker device 1 further includes an audio input circuit 16, and the audio input circuit 16 is configured to collect sound of a user wearing the speaker device 1, and transmit audio information collected by the sound to the mobile terminal through the first wireless communication chip 12 and/or the second wireless communication chip 13, so that a corresponding receiving party can receive audio information conveyed by the user wearing the speaker device 1. The audio input circuit 16 may include a microphone or the like. For the speaker device 1 in the form of a headphone, it is generally equipped with a microphone as an element for picking up audio in the audio input circuit 16.
Normally, only one set of audio input circuits 16 is provided in the speaker device 1, and therefore the first wireless communication chip 12 and the second wireless communication chip 13 share the audio input circuits 16. Meanwhile, the speaker device 1 further includes a second switch 161, and the second switch 161 is configured to selectively conduct the first wireless communication chip 12 and the audio input circuit 16, or conduct the second wireless communication chip 13 and the audio input circuit 16, so as to enable input of audio information transmitted by the first wireless communication chip 12 and the second wireless communication chip 13.
Specifically, the control terminal 1611 of the second switch 161 is connected to the first control circuit 11, the input terminal 1612 of the second switch 161 is connected to the audio input circuit 16, the first output terminal 1613 of the second switch 161 is connected to the first wireless communication chip 12, and the second output terminal 1614 of the second switch 161 is connected to the second wireless communication chip 13.
When the mode switch 14 instructs the first control circuit 11 to control the first wireless communication chip 12 to perform audio information interaction, the first control circuit 11 controls the first output 1613 of the second switch 161 and the input 1612 of the second switch 161 to be conducted through the second switch 161, i.e. to make the first wireless communication chip 12 and the audio input circuit 16 be conducted; when the mode switch 14 instructs the first control circuit 11 to control the second wireless communication chip 13 to perform audio information interaction, the first control circuit 11 controls the second output 1614 of the second switch 161 and the input 1612 of the second switch 161 to be turned on through the second switch 161, that is, the second wireless communication chip 13 and the audio input circuit 16 are turned on.
In an embodiment, the speaker device 1 further includes a first antenna 171 and a second antenna 172, the first antenna 171 is connected to the first wireless communication chip 12, the second antenna 172 is connected to the second wireless communication chip 13, the first wireless communication chip 12 performs audio information interaction through the first antenna 171, and the second wireless communication chip 13 performs audio information interaction through the second antenna 172.
Specifically, when the mode switch 14 instructs the first control circuit 11 to control the first wireless communication chip 12 to perform audio information interaction, the first wireless communication chip 12 performs audio information interaction through the first antenna 171; or when the mode switch 14 instructs the first control circuit 11 to control the second wireless communication chip 13 to perform audio information interaction, the second wireless communication chip 13 performs audio information interaction through the second antenna 172; or when the mode switch 14 instructs the first control circuit 11 to control the first wireless communication chip 12 and the second wireless communication chip 13 to perform audio information interaction together, the first wireless communication chip 12 performs audio information interaction through the first antenna 171, and the second wireless communication chip 13 performs audio information interaction through the second antenna 172.
It should be noted that the working frequency bands of the first wireless communication chip 12 and the second wireless communication chip 13 for performing audio information interaction may be the same, for example, the first wireless communication chip 12 is a 2.4GHz communication chip based on a 2.4GHz wireless audio private protocol, and the second wireless communication chip 13 is a bluetooth communication chip. The first wireless communication chip 12 can avoid the mutual interference between the first wireless communication chip 12 and the second wireless communication chip 13 by modifying the communication protocol on which the first wireless communication chip 12 is based so that the channel for transmitting the audio information of the first wireless communication chip 12 is different from the channel for transmitting the audio information of the second wireless communication chip 13.
Of course, the working frequency bands of the first wireless communication chip 12 and the second wireless communication chip 13 for audio information interaction may also be different, for example, the first wireless communication chip 12 is a 5.8GHz communication chip based on a 5.8GHz wireless audio proprietary protocol, and the second wireless communication chip 13 is a bluetooth communication chip. In this case, the working frequency bands of the first wireless communication chip 12 and the second wireless communication chip 13 for performing audio information interaction are different, so that the first wireless communication chip 12 and the second wireless communication chip 13 do not interfere with each other.
Please refer to fig. 2. In an alternative embodiment, when the first wireless communication chip 12 is a 2.4GHz communication chip and the second wireless communication chip 13 is a bluetooth communication chip, it means that the operating frequency bands of the first wireless communication chip 12 and the second wireless communication chip 13 for audio information interaction are the same, so that the first wireless communication chip 12 and the second wireless communication chip 13 can share one antenna, thereby reducing the use of the antenna in the speaker device 1, facilitating the miniaturization of the speaker device 1 and reducing the manufacturing cost of the speaker device 1.
Further, the speaker device 1 further includes a common antenna 173 and a third switch 174. The first wireless communication chip 12 and the second wireless communication chip 13 both perform audio information interaction through the common antenna 173. Since the audio information transmitted by the first wireless communication chip 12 and the second wireless communication chip 13 will interfere with each other when the common antenna 173 simultaneously receives the audio information transmitted by the first wireless communication chip 12 and the second wireless communication chip 13, the third switch 174 is required to selectively turn on the first wireless communication chip 12 and the common antenna 173 or turn on the second wireless communication chip 13 and the common antenna 173, i.e. the first wireless communication chip 12 and the common antenna 173 and the second wireless communication chip 13 and the common antenna 173 are alternately turned on at different times, so that the common antenna 173 only receives the audio information transmitted by the first wireless communication chip 12 or the second wireless communication chip 13 at the same time.
Specifically, the control terminal 1741 of the third switch 174 is connected to the first control circuit 11, the first terminal 1742 of the third switch 174 is connected to the common antenna 173, the second terminal 1743 of the third switch 174 is connected to the first wireless communication chip 12, and the third terminal 1744 of the third switch 174 is connected to the second wireless communication chip 13.
When the mode switch 14 instructs the first control circuit 11 to control the first wireless communication chip 12 to perform audio information interaction, the first control circuit 11 turns on the first terminal 1742 and the second terminal 1743 through the control terminal 1741 of the third switch 174, i.e., turns on the first wireless communication chip 12 and the common antenna 173; or when the mode switch 14 instructs the first control circuit 11 to control the second wireless communication chip 13 to perform audio information interaction, the first control circuit 11 turns on the first terminal 1742 and the third terminal 1744 through the control terminal 1741 of the third switch 174, that is, turns on the second wireless communication chip 13 and the common antenna 173; or when the mode switch 14 instructs the first control circuit 11 to control the first wireless communication chip 12 and the second wireless communication chip 13 to perform audio information interaction together, the first terminal 1742 and the second terminal 1743, and the first terminal 1742 and the third terminal 1744 are alternately turned on in time division, that is, the first wireless communication chip 12 and the common antenna 173, and the second wireless communication chip 13 and the common antenna 173 are alternately turned on in time division.
In the case where the mode switch 14 instructs the first control circuit 11 to control the first wireless communication chip 12 and the second wireless communication chip 13 to perform audio information interaction together, since the frequency of the time-sharing alternative conduction between the first end 1742 and the second end 1743 and between the first end 1742 and the third end 1744 is very high, the user cannot perceive the delay caused by the time-sharing alternative audio information interaction between the first wireless communication chip 12 and the second wireless communication chip 13, and the normal use experience of the user is not affected.
When the working frequency bands of the first wireless communication chip 12 and the second wireless communication chip 13 for audio information interaction are different, for example, the first wireless communication chip 12 is a 5.8GHz communication chip, and the second wireless communication chip 13 is a bluetooth communication chip, the antenna structures adapted to the first wireless communication chip 12 and the second wireless communication chip 13 will be different, so that the first wireless communication chip 12 and the second wireless communication chip 13 cannot share the antenna in this case.
Please continue to refer to fig. 1. In one embodiment, the speaker device 1 further includes a first interface 181, a charging chip 182, and a battery 183. The first interface 181 is respectively connected to the first control circuit 11 and the charging chip 182, so that data can be exchanged between the first interface 181 and the first control circuit 11, and the first interface 181 can output the received electric energy to the charging chip 182, so as to charge the battery 183. The charging chip 182 is further connected to the battery 183, and the charging chip 182 can use the power from the first interface 181 to charge the battery 183 and adjust a charging mode of the battery 183, such as a constant current to constant voltage charging mode. The battery 183 is also connected to the first control circuit 11 and the charging chip 182, respectively, for supplying power to the first control circuit 11 and the charging chip 182. The first interface 181 may be a Type-C interface or the like.
The speaker device 1 further includes a first Power Management Unit 184, which may be a Power Management Unit (PMU), where the first Power Management Unit 184 is connected to the first wireless communication chip 12 for performing Power Management on the first wireless communication chip 12. The first power management unit 184 is further connected to a battery 183 for supplying power to the first power management unit 184.
The speaker device 1 further includes a power key 185, a volume up key 186, a volume down key 187, and an LED lamp group 188. The power key 185, the volume up key 186, the volume down key 187 and the LED lamp set 188 are respectively connected to the first control circuit 11. The power key 185 is used to control the on and off of the speaker device 1; the volume up key 186 is used to increase the volume of the audio output from the speaker device 1, and the volume down key 187 is used to decrease the volume of the audio output from the speaker device 1; the LED lamp group 188 is used to display the current state of the loudspeaker device 1, including the current remaining power of the loudspeaker device 1, whether the loudspeaker device 1 is in an on or off state, the current audio information transmission mode of the loudspeaker device 1, and the like.
In summary, in the speaker device provided by the present invention, the first wireless communication chip and the second wireless communication chip implement audio information interaction between the speaker device and the mobile terminal through a wireless communication manner, so as to avoid adverse effects on the convenience of use of the user caused by the wired speaker device, and improve the convenience of use of the speaker device. And the time delay of the audio information transmission of the first wireless communication chip is lower than the time delay of the audio information transmission of the second wireless communication chip, so that compared with the second wireless communication chip, the audio information transmission of the first wireless communication chip can reduce the time delay of the audio information transmission between the loudspeaker device and the mobile terminal. And according to the requirement of the audio information to be transmitted on transmission delay, a proper wireless communication chip can be selected for audio information interaction.
Referring to fig. 3, fig. 3 is a schematic structural diagram of an embodiment of a transfer apparatus in the present invention.
In one embodiment, the relay device 2 includes a second control circuit 21 and a third wireless communication chip 22. The third wireless communication chip 22 is connected to the second control circuit 21, and the third wireless communication chip 22 is further used for connecting a speaker device, so that the speaker device performs audio information interaction with the mobile terminal through the relay device 2.
As described in the foregoing embodiment, when the speaker device, the relay device 2 and the mobile terminal are applied to transmission of audio information requiring low transmission delay, for example, audio of a game with high real-time performance is transmitted, the relay device 2 may be a game pad, which provides a richer and more convenient control experience to a user while serving as a medium for audio information interaction between the speaker device and the mobile terminal. Of course, in other application environments, the relay device 2 may only serve as a medium for audio information interaction between the speaker device and the mobile terminal, similar to a signal transceiver, and is not limited herein.
The time delay of the third wireless communication chip 22 for transmitting the audio information is shorter than the time delay of the bluetooth communication chip for transmitting the audio information. Specifically, the third wireless communication chip 22 may be a 2.4GHz communication chip, which is based on a 2.4GHz wireless audio private protocol; or the third wireless communication chip 22 may also be a 5.8GHz communication chip, etc., and is based on a 5.8GHz wireless audio proprietary protocol. The reason why the delay of the 2.4GHz communication chip and the 5.8GHz communication chip for transmitting the audio information is low has been described in the above embodiments, and will not be described herein again. Of course, the third wireless communication chip 22 is preferably connected with an antenna for transmitting audio information with the speaker device.
Therefore, when the audio information requiring low transmission delay is transmitted between the speaker device and the mobile terminal, the audio information requiring low transmission delay interacted between the speaker device and the mobile terminal is forwarded to the corresponding speaker device or the mobile terminal via the third wireless communication chip 22 of the relay device 2. Therefore, the audio information is transmitted between the speaker device and the mobile terminal through the third wireless communication chip 22 of the relay device 2, so that the delay of transmitting the audio information between the speaker device and the mobile terminal can be reduced, and the requirement of the audio information on the transmission delay can be met.
Alternatively, the second control circuit 21 may be a chip integrated with a logic operation circuit, such as an MCU (micro controller Unit) or LAM2, and may be capable of acquiring authority authentication of different operating systems (e.g., Android or IOS), so that the relay device 2 has a function of performing audio information interaction with mobile terminals of different operating systems. The third wireless communication chip 22 may have not only the function of transmitting and receiving signals but also the function of encoding and decoding; or the third wireless communication chip 22 may only have the function of transmitting and receiving signals, and the function of encoding and decoding is implemented by the second control circuit 21, which is not limited herein.
Further, the relay device 2 further includes a second interface 23, the second interface 23 is connected to the second control circuit 21, and the second interface 23 is further used for connecting the mobile terminal, so as to transmit the audio information from the mobile terminal to the third wireless communication chip 22 via the second control circuit 21, or transmit the audio information from the speaker device to the mobile terminal via the third wireless communication chip 22 and the second control circuit 21; and the second interface 23 is also used to charge the relay device 2 with power from the mobile terminal or to supply power received by the relay device 2 to the mobile terminal for charging. The second interface 23 may be a Type-C interface, a Lightning interface, or the like.
Further, the relay device 2 further includes a third interface 24, the third interface 24 is connected to the second control circuit 21, and the third interface 24 is also used for connecting an external power supply and the like. In this way, the third interface 24 can obtain power from the external power source and transmit the power to the mobile terminal through the second control circuit 21 and the second interface 23, so that the mobile terminal can be charged through the relay device 2 during the use of the relay device 2, and the mobile terminal can be connected to the relay device 2 and can be charged. The third interface 24 may be a Type-C interface, a Lightning interface, or the like.
In the prior art, a mobile terminal usually only has one interface designed to be connected with an external device (including an external power supply, a transfer device, etc.), which results in that the external power supply cannot be connected after the second interface of the mobile terminal and the transfer device is connected, i.e., the mobile terminal cannot be charged in the using process, and thus the duration of the mobile terminal is short. In the embodiment, by designing the third interface 24 on the relay device 2, the mobile terminal can be connected to the relay device 2 and can perform a charging function.
Further, the relay device 2 further comprises a second power management unit 25, which may also be PMU in nature. The second power management unit 25 is connected between the second interface 23 and the second control circuit 21, and both the power from the second interface 23 or the third interface 24 can be used to power the second power management unit 25. The relay device 2 further includes a human-computer interaction circuit 26, and the second power management unit 25 is further connected to the third wireless communication chip 22 and the human-computer interaction circuit 26, respectively, so as to supply power to the third wireless communication chip 22 and the human-computer interaction circuit 26 and perform power management. When the relay device 2 is a joystick, the handle and the keys connected to the man-machine interaction circuit 26 are provided for the user to operate, and thus operate the mobile terminal. The man-machine interaction circuit 26 is further connected to the third wireless communication chip 22, and a command input by the user through the man-machine interaction circuit 26 passes through the third wireless communication chip 22 and is transmitted to the mobile terminal through the second control circuit 21 and the second interface 23, so that the function of controlling the mobile terminal is realized.
As can be seen from the above, the relay device provided by the present invention is connected to the mobile terminal through the second interface, so that the delay of data transmission (including audio information) between the relay device and the mobile terminal is low; and the relay device performs audio information interaction with the speaker device through the third wireless communication chip, so that the delay of data transmission (including audio information) between the relay device and the speaker device is low. By combining the two points, the audio information interaction mode between the loudspeaker device and the mobile terminal by the aid of the transfer device has lower transmission delay, and the delay of audio information transmission between the loudspeaker device and the mobile terminal can be reduced.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a mobile terminal according to an embodiment of the present invention.
In an embodiment, the mobile terminal 3 includes a third control circuit 31 and a communication circuit 32, the communication circuit 32 is connected to the third control circuit 31, and the communication circuit 32 is further configured to be connected to a relay device, so as to perform audio information interaction through the relay device and a speaker device. Or the communication circuit 32 is also used for connecting with a loudspeaker device so as to directly interact audio information with the loudspeaker device.
When the communication circuit 32 is connected to the relay device, the communication circuit 32 of the mobile terminal 3 performs audio information interaction with the speaker device through the relay device; when the communication circuit 32 is connected to the speaker device, the communication circuit 32 of the mobile terminal 3 directly performs audio information interaction with the speaker device; when the communication circuit 32 is connected to the relay device and the speaker device, the communication circuit 32 performs interaction of the first audio information through the relay device and the speaker device, and the second wireless communication chip performs interaction of the second audio information with the mobile terminal 3. Wherein the required transmission delay of the first audio information is lower than the required transmission delay of the second audio information.
Since the first wireless communication chip of the speaker device is based on the 2.4GHz wireless audio private protocol or the 5.8GHz wireless audio private protocol, and the protocol based on which the communication circuit 32 of the mobile terminal 3 wirelessly transmits signals is usually a bluetooth communication protocol, the first wireless communication chip of the speaker device cannot directly perform audio information interaction with the communication circuit 32 of the mobile terminal 3, and a relay device is needed.
Alternatively, the third control circuit 31 may be a chip integrated with a logic operation circuit, and the communication circuit 32 is integrated with a bluetooth communication chip. The third control circuit 31 is configured to control the communication circuit 32 to screen the transmitted audio information, specifically, to screen out audio information (for example, game audio) requiring low transmission delay, and transmit the audio information to the relay device (for example, to the second interface of the relay device in the foregoing embodiment) through the communication circuit 32, where the communication circuit 32 is provided with a corresponding interface and is in butt joint with the second interface, and wired data transmission between the interfaces also has low transmission delay), so as to transmit the audio information to the speaker device through the relay device; and other audio information is directly transmitted to the loudspeaker equipment by using Bluetooth through the Bluetooth communication chip.
Further, when the communication circuit 32 is connected to the relay device and the speaker device at the same time, and when the first audio information and the second audio information simultaneously and directly transmitted to the relay device and the speaker device by the communication circuit 32 interfere with each other, the first wireless communication chip and the second wireless communication chip of the speaker device in the above embodiment have the same frequency band for audio information interaction, and the first wireless communication chip and the second wireless communication chip share one antenna, the process of transmitting the first audio information and the second audio information by the communication circuit 32 can be performed alternately in time sharing to avoid mutual interference between the first audio information and the second audio information, meanwhile, due to the fact that the frequency of the time-sharing alternation is very high, a user cannot perceive the time delay caused by the time-sharing alternation of the first audio information and the second audio information, and the normal use experience of the user is not influenced.
As can be seen from the above, in the mobile terminal provided by the present invention, the time delay for the communication circuit to transmit the audio information through the relay device and the speaker device is shorter than the time delay for the communication circuit to directly transmit the audio information through the speaker device, so that the mobile terminal can reduce the time delay for transmitting the audio information between the speaker device and the mobile terminal by transmitting the audio information through the relay device and the speaker device.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
