The technical solutions in the embodiments of the present application are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present application. It is a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without departing from the inventive scope are the scope of the present application.

The audio wireless communication method and apparatus provided by the embodiments of the present application are applicable to the application scenarios shown in FIG. 1a and FIG. 1b. In the application scenario shown in FIG. 1a and FIG. 1b, an audio playback device 10 and an audio source device 20 are included, wherein the audio source device 20 can be any suitable type of electronic device capable of providing one or more audio content. For example, smartphones, tablets, MP3 players, personal computers, CD players, etc. The audio playback device 10 includes a first playback device 11 and a second playback device 12. The audio playback device 10 can be any suitable electronic device capable of supporting multi-channel audio data, such as stereo headphones, 2.1 channel speakers, 5.1 sounds. Channel audio, stereo speakers or other suitable type of speaker set. The first playback device 11 and the second playback device 12 are only used to indicate a speaker portion for playing different channels. For example, for a stereo headset, the first playback device 11 may be a left channel headset, and the second playback device 12 For the right channel headphones.

In order to ensure the integrity of the data acquired by the second playback device 12, the embodiment of the present application is When the second playback device 12 acquires data through the interception mode (for example, receiving data error or losing data), the second playback device 12 sends an interference signal to prevent the audio source device 20 from receiving other signals. Therefore, when the second playback device 12 receives data errors or loses data, the audio source device 20 will not receive other signals due to the interference signals transmitted by the second playback device 12. Then, the audio source device 20 re-sends the data to the first playback device 11, and the second playback device 12 can obtain the data sent by the audio source device 20 by means of the interception, thereby ensuring the integrity of the data received by the second playback device 12. Sex.

The embodiment of the present application provides an audio wireless communication method, which may be performed by the audio playback device 10 in FIG. 1a and FIG. 1b. As shown in FIG. 3, the method includes:

101: The first playing device 11 performs wireless communication with the audio source device 20 to acquire data transmitted by the audio source device 20.

102: The second playback device 12 acquires data from the audio source device 20 by means of data interception during at least part of the wireless communication process.

Please refer to phase A in FIG. 2 and FIG. 4 (wherein T1 represents the timing of the audio source device 20, T2 represents the timing of the first playback device 11, and T3 represents the timing of the second playback device 12), the first playback device 11 and The audio source device 20 establishes a wireless communication connection through the connection information A and the connection information B. The first playback device 11 and the second playback device 12 establish a wireless communication connection by using the connection information C and the connection information D, and send information such as a connection key and an address of the audio source device 20 to the second playback device 12, and the second playback device The information of the audio source device 20 and the first playback device 11 can be monitored by the information, and the data sent by the audio source device 20 to the first playback device 11 can be obtained. Referring to the B phase in FIG. 4, the audio source device 20 starts to send data to the first playback device 11, the first playback device 11 receives the data sent by the audio source device 20, and the second playback device 12 acquires the audio source by means of interception. The data transmitted by the device 20 to the first playback device 11.

103: If the second playback device 12 acquires data incorrectly, the interference signal is sent out to prevent the audio source device from receiving the acknowledgement received signal.

In some embodiments, when the first playback device 11 successfully receives the data, an acknowledgment receipt signal is sent to the audio source device 20 to inform the audio source device 20 that the next packet of data can be transmitted. In other embodiments, the audio source device may also be notified by the other signal (eg, a clock signal) to transmit the next packet of data. When the second playback device 12 acquires data incorrectly, the interference signal is sent out. If the audio source device 20 does not receive the acknowledged received signal or other signal due to the presence of the interference signal, the data is retransmitted.

When the first playback device 11 successfully receives the data, an acknowledgment receiving signal is sent to the audio source device 20 to inform the audio source device 20 that the next packet data can be sent as an example.

Referring to the D phase in FIG. 4, when the first playback device 11 successfully receives the data sent by the audio source device 20, the first playback device 11 sends an acknowledgment reception signal (which can be sent by the ACK signal) to the audio source device 20, The audio source device 20 is required to transmit the next data packet. If the second playback device 12 does not successfully obtain the data that the audio source device 20 sends to the first playback device 11 (eg, receives data error or loses data), then the first playback device 11 transmits an acknowledgment received signal to the audio source device 20. During the same period, the second playback device 12 transmits an interference signal to the outside. Due to the presence of the interference signal, the audio source device 20 will not receive the acknowledgement received signal, so that the first playback device 11 does not receive the previous packet data, and the packet data is automatically retransmitted. In this way, the second playback device 12 can obtain the data retransmitted by the audio source device 20 by means of the interception to ensure that the second playback device 12 completely receives the data sent by the audio source device 20.

When the first playback device 11 and the second playback device 12 successfully receive the data, please refer to the C stage in FIG. 4, and the audio source device 20 will receive the first playback device 11 because there is no interference signal. The received signal is acknowledged and the next packet of data is started to be transmitted, and both the first playback device 11 and the second playback device 12 are ready to receive the next packet of data. The interference signal may be in various forms, for example, a signal with the same frequency and a higher power is used, which is not limited in this embodiment.

Since there is a process of interaction between the first playback device 11 and the audio source device 20, the communication process between the two is normal point-to-point communication, and therefore, the integrity of the data received by the first playback device 11 has a certain Protection.

Send a reception failure signal. Specifically, the reception failure signal may be sent by using an ACK signal.

Thus, when the second playback device 12 successfully receives the data and the first playback device 11 does not successfully receive the data, since the audio source device 20 receives the reception failure signal transmitted by the first playback device 11, the data packet is retransmitted. The first playback device 11 already knows that the previous packet data has a problem and needs to receive the retransmitted data packet, and when the second playback device 12 acquires the data packet retransmitted by the audio source device 20, the packet data is found to be the same as the previous packet data. The packet data will be automatically discarded or overwritten without affecting the reception of the previous packet of data.

When the data received by the first playback device 11 and the second playback device 12 are both incorrect, the first playback device 11 sends a reception failure signal to the audio source device 20, and the second playback device 12 transmits the interference signal. Due to the presence of the interfering signal, the audio source device 20 will not receive any signal from the first playback device 11, and will therefore retransmit the data packet. The first playback device 11 and the second playback device 12 both know that there is a problem with the previous packet data, and receive the data packet retransmitted by the audio source device 20, so that both the first playback device 11 and the second playback device 12 can receive the packet normally. data.

In some embodiments of the present application, referring to the B stage of FIG. 4, the first playing device 11 transmits the acknowledgment receiving signal or the receiving failure signal to the audio source device 20, and the second playing device listens through the data. The method obtains the acknowledgement receiving signal or the receiving failure signal. When the second playback device 12 receives the data incorrectly, the first playback device 11 transmits the interference signal to the audio source device 20 while transmitting the acknowledgement signal or the reception failure signal, and the second playback device 12 successfully receives the interference signal. During the same period of time when the first playback device 11 sends the acknowledgment received signal or the received failure signal to the audio source device 20, the second playback device 12 is also in the receiving state, and the first playback device is acquired by means of data interception. 11 acknowledging the received signal or receiving the failure signal to confirm that the first playback device 11 receives the previous packet data, thereby determining whether the audio source device 20 transmits the new data packet or the retransmitted data packet again to determine the pair. The obtained data packet is discarded, covered, or received.

In other embodiments of the present application, referring to the C stage of FIG. 4, the first playback device 11 transmits only the acknowledgment reception signal or the reception failure signal to the audio source device 20. When the second playback device 12 receives the data incorrectly, the first playback device 11 transmits the interference signal to the audio source device 20 during the same period of time to send the acknowledgement received signal or the receive failure signal, and the second playback device 12 successfully receives the interference signal. When you get to the data, do nothing. The second playback device 12 does not confirm the case where the first playback device 11 receives the data packet, and only determines the data packet when the data packet sent by the audio source device 20 is acquired, if the data packet is followed by the received previous data packet. If the packet is the same, the packet is discarded or overwritten, otherwise it is received.

Of course, in other embodiments of the present application, the first playback device 11 may also send an acknowledgment received signal to the second playback device 12 only when transmitting the acknowledgment received signal to the audio source device 20, or only to the audio source. The device 20 transmits a reception failure signal to the second playback device 12 while transmitting the reception failure signal. The second playback device 12 confirms that the first playback device 11 receives the previous packet data only by the acknowledge receipt signal or only the reception failure signal, thereby determining that the audio source device 20 transmits the new packet again. It is also a resent packet to determine whether to discard, overwrite, or receive the obtained packet.

The embodiment of the present application can enable the second playback device to completely receive data sent by the audio source device, and ensure the integrity of the data received by the second playback device.
