Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

Please refer to FIG. 1 and FIG. 2 , which are a schematic diagram of the structure of an embodiment of a transmission system of Bluetooth audio packets and a flow chart of steps of an embodiment of a sharing method of Bluetooth audio packets of the present invention, respectively. The Bluetooth audio packet transmission system 10 described in the embodiment of the present invention includes an electronic device 11 and a first Bluetooth sounding device 13. For example, the electronic device 11 can be a computer with a Bluetooth device, a notebook computer, a mobile phone, a smart phone, a tablet Computer or player etc., and the first bluetooth sound generating device 13 can be bluetooth speaker, bluetooth headset or bluetooth hands-free handset and so on. The electronic device 11 can perform Bluetooth pairing with the first Bluetooth sound generating device 13 and complete the Bluetooth connection between the two. Then the first Bluetooth sounding device 13 can receive at least one audio packet (audio packet) 12 transmitted by the electronic device 11 through Bluetooth, and the Bluetooth sounding device 13 can calculate and convert the received audio packet 12, and play the converted audio packet 12.

In the embodiment of the present invention, the electronic device 11 is a master device (Master), and the first Bluetooth sound generating device 13 is a slave device (Slave). The electronic device 11 has a Bluetooth connection data 14, for example, the Bluetooth connection data 14 includes a Bluetooth device address (BD_ADDR), a Bluetooth frequency (BT clock), a channel map (channel map) and a connection key (link key). During the pairing process between the electronic device 11 and the first Bluetooth sounding device 13, the electronic device 11 will transmit the Bluetooth connection data 14 to the first Bluetooth sounding device 13, and the first Bluetooth sounding device 13 will pass the received Bluetooth The connection data 14 establishes a Bluetooth connection with the electronic device 11 , as shown in step 21 .

Generally speaking, the frequency range used by the Bluetooth device is about 2.400 to 2.4825 GHz, wherein this frequency range is divided into 79 channels, each with a bandwidth of 1 MHz.

Bluetooth devices usually use frequency hopping (Frequency hopping) technology to determine the channel for transmitting data. The electronic device 11 (master device) and the first Bluetooth sounding device 13 (slave device) will calculate a group of nearly random hops according to the Bluetooth device address (BD_ADDR) of the electronic device 11 and the current Bluetooth frequency (BT clock) of the electronic device 11. Frequency sequence (Pseudo-random hopping sequence), and then the electronic device 11 and the first Bluetooth sounding device 13 will select the channel for transmitting the audio packet 12 according to the calculated sequence.

In addition, the electronic device 11 (main device) also includes a channel map, wherein the channel map can be used to indicate unused or uninterferenced channels among the 79 channels. For example, some of the 79 channels may be occupied or interfered, so that the electronic device 11 and the first Bluetooth sound generating device 13 cannot transmit data through these occupied or interfered channels.

For this reason, the electronic device 11 and the first Bluetooth sound generating device 13 not only select the channel for transmitting the audio packet 12 according to the calculated sequence, but also exclude channels that are currently occupied or interfered with according to the content of the channel map.

In addition, when the electronic device 11 and the first Bluetooth sound generating device 13 transmit the audio packet 12 through Bluetooth, they will also encrypt and decrypt the audio packet 12 with a corresponding key. For example, the electronic device 11 encrypts the audio packet 12 through the key and transmits the encrypted audio packet 12 , and the first Bluetooth sound generating device 13 decrypts the received audio packet 12 through the key.

After the electronic device 11 and the first Bluetooth sounding device 13 complete the Bluetooth connection, the electronic device 11 can transmit at least one audio packet 12 via Bluetooth, and the first Bluetooth sounding device 13 will return a response after receiving the audio packet 12 A signal (ACK; positive acknowledgment) 161 is sent to the electronic device 11 . After receiving the response signal 161 , the electronic device 11 can know that the first Bluetooth sound generating device 13 has indeed received the previously transmitted audio packet 12 , and can continue to transmit other audio packets 12 .

On the contrary, if the first Bluetooth sound generating device 13 does not receive the audio packet 12 , it may return a negative acknowledgment signal (NACK; negative acknowledgment) 163 to the electronic device 11 . After receiving the negative response signal 163 , the electronic device 11 will know that the first Bluetooth sound generating device 13 has not received the previously transmitted audio packet 12 , and will retransmit the previously transmitted audio packet 12 .

However, in another practical example of the present invention, when the first Bluetooth sound generating device 13 does not receive the audio packet 12 , it may not return the negative response signal 163 to the electronic device 11 . At this time, the electronic device 11 can be set such that when the response signal 161 returned by the first Bluetooth sound generating device 13 is not received, the electronic device 11 will consider that the first Bluetooth sound generating device 13 has not received the previously transmitted audio packet 12 , and transmit the previously transmitted audio packet 12 again.

The bluetooth connection data 14 and the method for establishing the bluetooth connection between the electronic device 11 and the first bluetooth sound generating device 13 described in the above-mentioned embodiments of the present invention are all bluetooth technologies commonly used at present. For this reason, in the above-mentioned embodiments of the present invention, the relevant technical content is only briefly described. Those with ordinary knowledge in the technical field of the present invention can refer to the currently published Bluetooth data to know the above-mentioned Bluetooth connection data 14 and the establishment of the Bluetooth connection. content.

The main technical feature of the present invention is that after the first Bluetooth sounding device (slave device) 13 learns the Bluetooth connection data 14 of the electronic device (master device) 11, or establishes a Bluetooth connection with the electronic device 11 through the Bluetooth connection data 14, The Bluetooth connection data 14 will be broadcast, as shown in step 23. For this reason, if there are other Bluetooth sounding devices in the vicinity of the electronic device 11 and the first Bluetooth sounding device 13, for example, other Bluetooth sounding devices are close to the electronic device 11 and the first Bluetooth sounding device 13, then the Bluetooth sounding device will be The Bluetooth connection data 14 broadcasted by the first Bluetooth sound generating device 13 is received, and the detailed content will be described in subsequent embodiments. Of course, in actual application, other bluetooth sound generating devices are not essential components of the present invention, nor are they limited by the scope of rights of the present invention.

Please refer to FIG. 3 and FIG. 4 , which are a structural diagram of an embodiment of a Bluetooth audio packet sharing system and a flow chart of steps in another embodiment of a Bluetooth audio packet sharing method according to the present invention, respectively. The Bluetooth audio packet sharing system 100 described in the embodiment of the present invention includes an electronic device 11, a first Bluetooth sounding device 13 and at least one second Bluetooth sounding device 15, for example, the electronic device 11 can be a computer or notebook with a Bluetooth device Computers, mobile phones, smart phones, tablet computers, or players, etc., while the first Bluetooth sound generating device 13 and the second Bluetooth sound generating device 15 can be Bluetooth speakers, Bluetooth earphones, or Bluetooth hands-free handsets.

The first Bluetooth sound generating device 13 establishes a Bluetooth connection with the electronic device 11 through the Bluetooth connection data 14 , as shown in step 21 . Then the first Bluetooth sounding device 13 will broadcast Bluetooth connection data 14, such as Bluetooth connection data 14 including Bluetooth device address (Bluetooth device address; BD_ADDR), Bluetooth frequency (BT clock), channel map (channel map) and connection key ( link key), as shown in step 23. The details of step 21 and step 23 have been disclosed in the above-mentioned embodiments of the present invention, and will not be repeated here.

When the second Bluetooth sounding device 15 is located in the vicinity of the electronic device 11 and the first Bluetooth sounding device 13, the second Bluetooth sounding device 15 will receive the Bluetooth connection data 14 broadcast by the first Bluetooth sounding device 13, as shown in step 25 . The main spirit and features of the present invention are that even if there is no second Bluetooth sounding device 15, the first Bluetooth sounding device 13 will still broadcast the Bluetooth connection data 14, and when the second Bluetooth sounding device 15 is close to the electronic device 11 and the first Bluetooth sounding device After the device 13, the Bluetooth connection data 14 will be received. Therefore, the second Bluetooth sound generating device 15 is not an essential component of the present invention, nor is it a limitation of the scope of the present invention.

Since the Bluetooth connection has been established between the electronic device 11 and the first Bluetooth sound generating device 13 , the first Bluetooth sound generating device 13 can receive the audio packet 12 transmitted by the electronic device 11 through Bluetooth. In addition, the second Bluetooth sound generating device 15 has already known the Bluetooth connection data 14 of the electronic device 11 and the first Bluetooth sound generating device 13, so the second Bluetooth sound generating device 15 can receive the audio packet 12 transmitted by the electronic device 11 through the Bluetooth connection data 14, such as Step 27 shows.

For the convenience of illustration, FIG. 3 of the present invention mainly takes one second Bluetooth sounding device 15 as an embodiment of the invention, but in actual application, the number of second Bluetooth sounding devices 15 may be multiple. Since the first Bluetooth sound generating device 13 transmits the Bluetooth connection data 14 by broadcasting, multiple second Bluetooth sound generating devices 15 can receive the Bluetooth connection data 14, and multiple second Bluetooth sound generating devices 15 can all be connected via Bluetooth. The data 14 receives the audio packet 12 transmitted by the electronic device 11 .

Through the content described in the present invention, although multiple Bluetooth sound generating devices can receive the audio packet 12 transmitted by the electronic device 11 . However, the method for the second Bluetooth sound generating device 15 to receive the audio packet 12 through the Bluetooth connection data 14 is similar to how the second Bluetooth sound generating device 15 eavesdrops on the audio packet 12 transmitted between the electronic device 11 and the first Bluetooth sound generating device 13 .

In fact, the electronic device 11 only establishes a Bluetooth connection with the first Bluetooth sound generating device 13 , while the other second Bluetooth sound generating devices 15 do not actually establish a Bluetooth connection with the electronic device 11 . Therefore, the electronic device 11 will not be aware that the second Bluetooth sounding device 15 is also receiving audio packets, and there is no need to change the method of Bluetooth connection and the method of transmitting the audio packet 12, so that multiple Bluetooth sounding devices can receive the audio packets transmitted by the electronic device 11. For example, the first Bluetooth sound generating device 13 and at least one second Bluetooth sound generating device 15 in the adjacent area will all receive the audio packet 12 transmitted by the electronic device 11 .

Generally speaking, after receiving the audio packet 12, the first Bluetooth sound generating device (slave device) 13 will perform a cyclic redundancy check (Cyclic redundancy check, CRC) to confirm whether the received audio packet 12 is correct. When the first Bluetooth sound generating device 13 receives the correct audio packet 12 sent by the electronic device 11 , it will return a response signal (ACK; positive acknowledgment) 161 to the electronic device 11 . After receiving the response signal 161 , the electronic device 11 will know that the first Bluetooth sound generating device 13 has received the previously transmitted audio packet 12 , and can continue to transmit other audio packets 12 to the first Bluetooth sound generating device 13 .

Conversely, if the first Bluetooth sound generating device 13 does not receive the audio packet 12 or receives a wrong audio packet 12, the first Bluetooth sound generating device 13 will not return the response signal 161 to the electronic device 11, or may return a response signal 161 to the electronic device 11. negative acknowledgment signal (NACK; negative acknowledgment) 163 to the electronic device 11 . When the electronic device 11 does not receive the response signal 161, or after receiving the negative response signal 163, it will know that the first Bluetooth sound generating device 13 has not received the previously transmitted audio packet 12, and will retransmit the previously transmitted audio packet 12. The audio packet 12 is sent to the first Bluetooth sound generating device 13 .

However, the second Bluetooth sound generating device 15 has not actually established a Bluetooth connection with the electronic device 11 , so the second Bluetooth sound generating device 15 cannot transmit the response signal 161 or the negative response signal 163 to the electronic device 11 . In this way, when the second Bluetooth sound generating device 15 does not receive the audio packet 12 or receives a wrong audio packet 12 , the electronic device 11 will not retransmit the previously transmitted audio packet 12 .

In order to avoid the above problems, the present invention further provides two methods, which can increase the probability that the second Bluetooth sound generating device 15 receives the audio packet. The first method is as follows: no matter whether the first Bluetooth sound generating device 13 actually receives the audio packet 12 sent by the electronic device 11, the first Bluetooth sound generating device 13 will send a negative response signal 163 to the electronic device 11 at least once, so that The electronic device 11 retransmits the same audio packet 12 .

The difference between the first method and the prior art is that even if the first Bluetooth sound generating device 13 has indeed received the correct audio packet 12 from the electronic device 11 , it will return at least one negative response signal 163 to the electronic device 11 . Of course, in actual application, the first Bluetooth sound generating device 13 may transmit the negative response signal 163 once or more than once, while the electronic device 11 may transmit the same audio packet 12 twice or more. In addition, when the first Bluetooth sound generating device 13 determines that it has received the correct audio packet 12 and has sent back one or more negative response signals 163, it will send a response signal 161 to the electronic device 11, so that the electronic device 11 can continue to transmit other The audio package 12.

Of course, in different embodiments, the first Bluetooth sound generating device 13 does not have to return the negative response signal 163 at least once to the electronic device 11 . For example, the electronic device 11 can be set such that when the response signal 161 returned by the first Bluetooth sound generating device 13 is not received, the electronic device 11 will consider that the first Bluetooth sound generating device 13 has not received the previously transmitted audio packet 12, And retransmit the audio packet 12 that has been transmitted before. For this reason, the first Bluetooth sound generating device 13 can be set to return the response signal 161 to the electronic device 11 after receiving two or more identical audio packets 12 . For example, when the first Bluetooth sounding device 13 receives the correct audio packet 12, it will not return the response signal 161 to the electronic device 11 immediately, and the electronic device 11 will think that the first Bluetooth sounding device 13 has not received the previous transmission. audio packet 12, and retransmit the previously transmitted audio packet 12.

Through the above-mentioned first method, the electronic device 11 will repeatedly transmit the same audio packet 12 twice or more, thereby effectively increasing the probability that each second Bluetooth sound generating device 15 actually receives the audio packet 12 .

The second method is as follows: when a second bluetooth sounding device 15 does not receive the audio packet 12 or receives a wrong audio packet 12, it will send an interference signal 18, wherein the frequency band of the interference signal 18 is the same as the response signal 161 the same frequency band. In addition, the time at which the second Bluetooth sounding device 15 transmits the interference signal is also the same as the time at which the first Bluetooth sounding device 13 transmits the response signal 161, so the interference signal 18 can interfere with the response signal 161 that the first Bluetooth sounding device 13 transmits to the electronic device 11. , and cause the electronic device 11 to fail to receive the response signal 161 transmitted by the first Bluetooth sound generating device 13 , so that the electronic device 11 retransmits the same audio packet 12 . In this way, although the second Bluetooth sound generating device 15 still cannot transmit the negative response signal 163 to the electronic device 11 , the electronic device 11 can still achieve the purpose of retransmitting the audio packet 12 that has already been transmitted.

Since the second Bluetooth sounding device 15 has already known the Bluetooth connection data 14 between the electronic device 11 and the first Bluetooth sounding device 13, the second Bluetooth sounding device 15 will naturally know the frequency and frequency of the response signal 161 sent back by the first Bluetooth sounding device 13. The time of transmitting the response signal 161 may therefore interfere with the response signal 161 , so that the electronic device 11 cannot receive the response signal 161 transmitted by the first Bluetooth sound generating device 13 .

Of course, in practical applications, the number of times that the second Bluetooth sounding device 15 continuously transmits the interference signal 18 can be limited, so as to avoid causing the entire Bluetooth audio packet to The sharing system 100 does not work.

In addition, in actual application, the above first method and the second method can also be executed at the same time, thereby further reducing the probability that the second Bluetooth sound generating device 15 fails to receive the audio packet 12 .

Since the second Bluetooth sound generating device 15 has not actually established an actual Bluetooth connection with the electronic device 11 and the first Bluetooth sound generating device 13 , the first Bluetooth sound generating device 13 and the second Bluetooth sound generating device 15 may not be able to play the audio packet 12 synchronously.

In another embodiment of the present invention, the first Bluetooth sound generating device 13 and the second Bluetooth sound generating device 15 can be further synchronized through the following method. Generally speaking, the audio packet 12 includes a plurality of samples, wherein the first Bluetooth sound generating device 13 and the second Bluetooth sound generating device 15 decode and/or convert the audio packet 12 .

The first bluetooth sound generating device 13 can capture the sample quantity of the converted audio packet 12 at the first time point, and generate a first sample quantity 171 , and the first bluetooth sound producing device 13 can further broadcast the first sample quantity 171 . The second bluetooth sound generating device 15 can capture the sample quantity of the converted audio packet 12 at the first time point, and generate a second sample quantity 173. In addition, the second bluetooth sound producing device 15 will receive the first bluetooth sound producing device 13 broadcast. The sample size is 171. Since the first Bluetooth sounding device 13 and the second Bluetooth sounding device 15 of the present invention have the same frequency, the first time point of the first Bluetooth sounding device 13 and the second Bluetooth sounding device 15 will be the same time point .

Then the second bluetooth sounding device 15 can further compare the first sample number 171 and the second sample number 173, if the first sample number 171 and the second sample number 173 at the same time point are the same, it means that the first bluetooth sounding device 13 Synchronize with the second Bluetooth sound generating device 15. Conversely, if the first sample number 171 and the second sample number 173 at the same time point are different, it means that the first Bluetooth sound generating device 13 and the second Bluetooth sound generating device 15 play the audio packet 12 out of sync. For this reason, the second bluetooth sounding device 15 can adjust the sample rate or sample rate (sample rate) of the conversion audio packet 12 according to the first sample quantity 171 and the second sample quantity 173, so that the first bluetooth sounding device 13 and the second The Bluetooth sound generating device 15 can play the audio package 12 synchronously.

Of course, in actual application, the above-mentioned synchronization method can be repeated, for example, it can be preset to repeat the above-mentioned synchronization method at a certain time interval, so that the first Bluetooth sound generating device 13 and the second Bluetooth sound generating device 15 can be continuously maintained. Synchronize. In addition, for the convenience of description, the above-mentioned embodiment of the present invention uses a second bluetooth sounding device 15 as an embodiment for illustration, but in actual application, the quantity of the second bluetooth sounding device 15 can also be multiple, and can Receive the first sample number 171 broadcast by the first Bluetooth sounding device 13, and use the rate or sampling rate of the first Bluetooth sounding device 13 to convert samples as a calibration benchmark, so that the first Bluetooth sounding device 13 and multiple second Bluetooth sounding The device 15 can play the audio package 12 synchronously.

The connection mentioned in the present invention refers to a direct connection or an indirect connection between one or more objects or components, for example, there may be one or more intermediate connections between one or more objects or components.
