[0035] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] In some embodiments, users use TWS headphones in a variety of scenarios, such as making phone calls, watching videos, and holding video conferences; the environments in which TWS headphones are used include outdoors, offices, airports, stations, and other environments. Since TWS uses Bluetooth wireless communication technology, it has natural disadvantages compared to corded headphones. For example, the quality of the transmission signal is greatly affected by the transmission distance and is easily interfered by other electromagnetic wave signals around it. In particular, the Bluetooth signal uses the unlicensed Industrial, Scientific and Medical (ISM) 2.4 Gigabit (G) frequency band, and many devices also work in this frequency band, such as microwave ovens, cordless phones, infrared, wireless cameras, etc. Therefore, the Bluetooth signal is easily interfered by surrounding signals.

[0037] The Bluetooth headset in the related technology has only one earphone, because the mobile phone can only communicate with one peer device at the same time. In order to achieve that both earphones of the TWS headset can receive the data packets from the mobile phone and play them at the same time, the related technology maintains connection and interactive communication between the master ear and the mobile phone, and the slave ear maintains connection and interactive communication with the master ear while listening to the interactive data packets between the master ear and the mobile phone. When the slave ear successfully monitors the data packet, the slave ear sends a paging (page) confirmation packet to the master ear before the end time when the master ear receives the data packet and the start time of replying to the mobile phone. The master ear replies to the mobile phone based on whether the master and slave ears have successfully received the data packet. When the master and slave ears have successfully received the audio data packet sent by the mobile phone, the master ear replies with an acknowledgment character packet (Acknowledge character, ACK) to the mobile phone. The mobile phone does not need to retransmit, but prepares to send the next packet of data. When either the master or slave ear fails to successfully receive the data packet, the master ear will reply with a non-acknowledgement character packet (Negative Acknowledgement, NAK) to the mobile phone. After receiving the NAK, the mobile phone retransmits the data packet to the headset until it receives the headset reply ACK packet. Such as Figure 1 As shown, for data packet 0 (packet0), both the master ear 12 and the slave ear 13 receive successfully, so there is no need to retransmit. When receiving packet 1, the slave ear fails to receive, causing the master ear 12 to reply NAK to the mobile phone 11, and the mobile phone 11 retransmits packet 1 once; then the master ear 12 fails to receive, causing the master ear 12 to reply NAK to the mobile phone 11, and the mobile phone 11 retransmits packet 1 for the second time. The last time, both the master ear 12 and the slave ear 13 receive successfully, and the master ear replies ACK to the mobile phone, and the mobile phone will not retransmit. When receiving packet2, both the master ear 12 and the slave ear 13 receive successfully, so there is no need to retransmit.

[0038] In actual applications, due to the user's usage scenario, one earphone is more likely to receive successfully, while the other earphone is not, which causes the mobile phone to frequently retransmit, but still fails to transmit. For example, when holding the mobile phone in the right hand, the right ear is closer to the visual distance, so it is easier to transmit successfully, while the left ear is more likely to fail to transmit because the signal is severely attenuated because it has to pass through the head. Therefore, blindly requiring the mobile phone to retransmit cannot solve the problem of data transmission failure.

[0039] Based on this, an embodiment of the present application provides an audio data transmission method. When the main terminal does not receive the monitoring confirmation information from the slave terminal, the number of retransmissions of the audio data by the sending end is counted to determine whether the number of retransmissions reaches a preset threshold; if the number of retransmissions is high, the main terminal forwards the audio data to the slave terminal, thereby reducing the number of times the sending end retransmits the audio data and improving the success rate of audio data transmission.

[0040] The audio data transmission method provided in the embodiment of the present application can be applied to Figure 2In the application environment shown. Among them, the main terminal 101 is connected to the transmitting terminal 102, and the main terminal 101 is connected to the slave terminal 103. The transmitting terminal 102 sends audio data to the main terminal 101, and the slave terminal 103 monitors the communication link between the transmitting terminal and the main terminal. If the main terminal 101 does not receive the monitoring confirmation information from the slave terminal 103, the number of retransmissions of the audio data by the transmitting terminal 102 is counted; if the number of retransmissions reaches the preset number threshold, the main terminal 101 forwards the audio data to the slave terminal 103 to reduce the number of retransmissions of the audio data by the transmitting terminal. Among them, the transmitting terminal 102 can be but not limited to various personal computers, laptops, smart phones, tablet computers, Internet of Things devices and portable wearable devices, and the Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The main terminal 101 and the slave terminal 103 can be the master ear and slave ear in a pair of Bluetooth headsets, or the master speaker and slave speaker in a pair of Bluetooth speakers, etc.

[0041] In one embodiment, Figure 3 As shown, a method for audio data transmission is provided, which is applied to Figure 2 The main terminal in the example is used as an example to illustrate, including the following steps:

[0042] Step 301, receiving the audio data sent by the sending end.

[0043] The audio data may be any type of audio, such as audio in Compact Disc (CD) format, audio in Waveform Audio File Format (WAV) format, audio in Media Player Three (MP3) format, audio in Windows Media Audio (WMA) format, or noise audio, etc. In some possible implementations, the master terminal receives the audio data first sent by the sender. Alternatively, the master terminal does not receive the audio data first sent by the sender, and returns a NAK to the sender, so that the sender retransmits the audio data until the master terminal receives the audio data.

[0044] Step 302: When no monitoring confirmation information is received from the slave terminal, determine the number of retransmissions of the audio data sent by the transmitting end to the master terminal.

[0045] The monitoring confirmation information is used to indicate that the slave terminal monitors that the master terminal receives the audio data sent by the transmitter. The number of retransmissions indicates the number of times the transmitter repeatedly sends the audio data to the master terminal. The transmitter is only connected to the master terminal, the slave terminal is connected to the master terminal, and the slave terminal is not connected to the transmitter. The slave terminal can monitor the communication link between the master terminal and the transmitter to monitor the data interaction between the master terminal and the transmitter.

[0046] Exemplarily, the transmitting end sends audio data to the main terminal, and the slave terminal monitors the audio data sent by the transmitting end to the main terminal. If the slave terminal monitors the audio data sent by the transmitting end to the main terminal, then the slave terminal transmits a monitoring confirmation message (e.g., a page packet) to the main terminal, so that the slave terminal informs the main terminal through the monitoring confirmation message that the audio data is successfully received from the slave terminal. In some possible implementations, if the main terminal does not receive the monitoring confirmation message from the slave terminal, it means that the slave terminal has not successfully monitored the audio data sent by the transmitting end to the main terminal. At this time, the main terminal returns the unconfirmed reception information to the transmitting end, so that the transmitting end retransmits the audio data; and starts to count the number of times the transmitting end retransmits the audio data. If the transmitting end still does not receive the monitoring confirmation message fed back by the slave terminal for the retransmitted audio data after retransmitting the audio data, then the number of retransmissions is increased by 1, so that the final number of retransmissions is obtained.

[0047] Step 303: when the number of retransmissions reaches a preset number threshold, forward the audio data to the slave terminal.

[0048] The preset number threshold can be user-defined or determined according to the data processing capability of the sending end. For example, if the data processing capability of the sending end is strong, the preset number threshold can be set to be slightly larger; if the data processing capability of the sending end is strong, the preset number threshold can be set to be slightly smaller.

[0049] Exemplarily, if the number of retransmissions reaches a preset number threshold, it means that the sender has repeatedly sent the audio data for a large number of times, and it also means that even if it is retransmitted many times, the slave terminal still cannot monitor the audio data. The master terminal returns confirmation information to the sender so that the sender will not continue to repeatedly transmit the audio data. And the master terminal forwards the received audio data to the slave terminal so that the slave terminal can receive the audio data and demodulate it. In this way, after the sender continues to retransmit, since the retransmission is invalid, further retransmission will waste more air interface resources. At this time, the master terminal directly forwards the audio data to the slave terminal, which can not only improve the data success rate, but also reduce the frequent transmission of audio data by the sender.

[0050] In an embodiment of the present application, if the master terminal does not receive the monitoring confirmation information from the slave terminal, it starts to count the number of retransmissions of the audio data by the sender to determine whether the number of retransmissions reaches a preset threshold; if the number of retransmissions is high, it means that after multiple retransmissions, the slave terminal still has not monitored the audio data. At this time, the master terminal forwards the audio data to the slave terminal; in this way, it can not only reduce the number of times the sender retransmits the audio data, but also improve the success rate of audio data transmission.

[0051] In one embodiment, in order to enable the main terminal connected to the transmitting end to receive the audio data with a stronger signal strength, Figure 4 The steps shown achieve:

[0052] Step 401 determines a first received signal strength of a signal received by the master terminal from a transmitting end and a second received signal strength of a signal received by the slave terminal from a transmitting end.

[0053] The first received signal strength is the signal strength of the transmitting end signal that can be received by the master terminal, and the second received signal strength is the signal strength of the transmitting end signal that can be received by the slave terminal. In some possible implementations, the master terminal receives the second received signal strength fed back by the slave terminal, and obtains the first received signal strength of the transmitting end signal received by itself.

[0054] Step 402: Determine whether to switch the master-slave relationship based on the first received signal strength and the second received signal strength.

[0055] In some possible implementations, by comparing the first received signal strength and the second received signal strength, the master-slave relationship between the master terminal and the slave terminal is switched according to the comparison result, so that the master-slave relationship between the master terminal and the slave terminal can match the respective received signal strengths. In this way, by analyzing the received signal strengths of the master terminal and the slave terminal respectively receiving the signal from the transmitting end, the master-slave relationship between the master terminal and the slave terminal is switched in real time, so that the master terminal connected to the transmitting end can always receive audio data with a stronger signal strength, thereby improving the accuracy of the master terminal receiving the audio data.

[0056] In some possible implementations, the above step 402 may be implemented by the following steps 421 (not shown):

[0057] Step 421: When the second received signal strength is greater than the first received signal strength, switching the master-slave relationship between the master terminal and the slave terminal.

[0058] Among them, after the master terminal receives the second received signal strength fed back from the slave terminal, it compares the numerical values ​​of the first received signal strength and the second received signal strength to obtain the numerical relationship. In this way, the numerical relationship includes: the first received signal strength is greater than the second received signal strength, or the first received signal strength is less than the second received signal strength. If the second received signal strength is greater than the first received signal strength, the master terminal switches to the slave terminal, disconnects from the transmitter, and monitors the audio data sent by the transmitter to the new master terminal; at the same time, the slave terminal receives the first received signal strength fed back from the master terminal, and by judging the numerical value between the first received signal strength and the second received signal strength, if the second received signal strength is greater than the first received signal strength, the slave terminal switches to the master terminal and connects to the transmitter.

[0059] Among them, if the numerical relationship indicates that the second received signal strength is greater than the first received signal strength, it means that the signal strength received from the terminal to the main terminal at the current moment is stronger, and the master-slave relationship between the main terminal and the slave terminal is switched in time. That is, the main terminal with a smaller received signal strength is switched to the slave terminal, and the slave terminal with a higher received signal strength is switched to the main terminal. In this way, when it is detected that the received signal strength of the slave terminal is greater than the received signal strength of the master terminal, the master-slave relationship between the master terminal and the slave terminal is switched in time, so that the master terminal is always the terminal with a larger received signal strength, thereby improving the success rate of the master terminal receiving audio data.

[0060] In one embodiment, in order to accurately count the number of times the master terminal retransmits the audio data, the above step 302 can be performed by Figure 5 The steps shown achieve:

[0061] Step 501: Returning non-acknowledgement information to the sending end when no monitoring confirmation information from the slave terminal is received, wherein the non-acknowledgement information is used to instruct the sending end to retransmit the audio data to the master terminal.

[0062] Among them, the unconfirmed information is used to indicate that at least one of the master terminal and the slave terminal has not obtained the audio data, and the sending end needs to retransmit the audio data. For example, the unconfirmed information can be a negative acknowledgement (NAK). If the master terminal does not receive the monitoring confirmation information from the slave terminal, it means that the slave terminal has not monitored the audio data and has not sent a page packet to the master terminal. While the monitoring confirmation information from the slave terminal is not received, the master terminal may have received the audio data or may not have received the audio data. In order to enable both the master terminal and the slave terminal to obtain the audio data, the master terminal sends the unconfirmed information to the sending end, and the sending end retransmits the audio data to the master terminal in response to the unconfirmed information. At the same time, the slave terminal monitors the retransmitted audio data, and may monitor the audio data or may not monitor the audio data. If the slave terminal monitors the audio data, the slave terminal feeds back monitoring confirmation information to the master terminal, the master terminal receives the monitoring confirmation information, and returns confirmation information to the sender. In this way, after receiving the confirmation information, the sender will not retransmit the audio data, but continue to send other audio data in the next clock cycle.

[0063] In some possible implementations, when the monitoring confirmation information of the slave terminal is not received and the master terminal itself has received the audio data, non-confirmation information is returned to the sending end, and a counter is started at the same time, and the counter counts to 1.

[0064] Step 502: if no monitoring confirmation information of the retransmitted audio data is received from the slave terminal, update the number of retransmissions.

[0065] If the monitoring confirmation information of the retransmitted audio data is not received from the slave terminal, it means that the slave terminal still has not monitored the retransmitted audio data of the sender. At this time, the count value is increased by 1, that is, the number of retransmissions is increased by 1, and so on, the number of retransmissions is increased one by one until the number of retransmissions reaches the preset number threshold. In this way, after the master terminal returns the unconfirmed information to the sender, the sender retransmits the audio data in response to the unconfirmed information. If the monitoring confirmation information from the slave terminal is still not received, the number of retransmissions is increased. In this way, the number of retransmissions of the audio data by the sender can be accurately counted.

[0066] If the monitoring confirmation information of the slave terminal is not received, the number of retransmissions of the audio data sent by the sender to the master terminal is counted. In order to reduce the frequent retransmission of the audio data by the sender, the above step 303 can be performed by Figure 6 Steps 601 and 602 shown implement:

[0067] Step 601: When the number of retransmissions reaches the preset number threshold, return confirmation information to the sending end.

[0068] The confirmation information is used to indicate that both the master terminal and the slave terminal have obtained the audio data, and the sender does not need to retransmit the audio data. In this way, the number of retransmissions reaches the preset number threshold, indicating that although the sender has retransmitted the audio data many times, the slave terminal still has not heard it, which means that the sender retransmitting the audio data cannot effectively solve the problem that the slave terminal cannot hear the audio data. Therefore, in order to reduce the frequent retransmission of the sender, the master terminal returns the confirmation information to the sender, so that the sender stops retransmitting the audio data in response to the confirmation information.

[0069] Step 602: forwarding the audio data to the slave terminal via a preset channel negotiated with the slave terminal.

[0070] Among them, the preset channel is the channel negotiated by the master terminal and the slave terminal, and the preset channel is different from the channel for transmitting data between the master terminal and the transmitter; in this way, although the transmitter stops retransmitting audio data and continues to transmit other audio data in the next clock cycle, the preset channel is different from the communication channel corresponding to the transmitter, so the master terminal will not be affected by the transmitter sending other audio data to the master terminal during the process of forwarding audio data to the slave terminal, which can improve the accuracy of the master terminal forwarding audio data. In this way, if the number of retransmissions has reached the preset number threshold, it means that the slave terminal still cannot monitor the audio data after the transmitter retransmits the audio data for many times, then the master terminal forwards the audio data to the slave terminal through the preset channel to improve the success rate of the slave terminal monitoring the audio data, and can control the transmitter from continuing to retransmit frequently.

[0071] After the above step 602, if the confirmation information is still not received, the master terminal continues to forward the audio data to the slave terminal so that the slave terminal can accurately receive the audio data, which can be achieved through step 603:

[0072] Step 603: In response to not receiving the confirmation information fed back by the slave terminal, continue to forward the audio data to the slave terminal until receiving the confirmation information fed back by the slave terminal.

[0073] If the master terminal still does not receive the confirmation information fed back by the slave terminal after forwarding the audio data to the slave terminal, it means that the slave terminal still has not received the forwarded audio data. At this time, the master terminal continues to send the audio data to the slave terminal until the slave terminal receives the audio data and transmits the confirmation information to the master terminal. In this way, it can ensure that the slave terminal successfully receives the audio data, so as to improve the accuracy of receiving the audio data from the slave terminal.

[0074] After the above step 602, if the master terminal receives the confirmation information, the master terminal switches from the preset channel to the communication channel for receiving the audio data to effectively receive the audio data sent by the transmitter in each clock cycle, which can be achieved by the following steps 604 and 605:

[0075] Step 604: In response to receiving the acknowledgement information fed back from the terminal, switching from the preset channel to the communication channel with the transmitting end.

[0076] If the master terminal receives the confirmation information fed back by the slave terminal, it means that the slave terminal has successfully received the audio data forwarded by the master terminal, and after successful demodulation, it feeds back ACK to the master terminal to indicate normal reception. In response to the confirmation information, the master terminal exits from the current preset channel and enters the communication channel with the transmitter; and after feeding back the confirmation information to the master terminal, the slave terminal also exits from the preset channel so as to correctly monitor the audio data sent by the transmitter to the master terminal.

[0077] Step 605: Receive the audio data sent by the transmitter on the communication channel.

[0078] After the master terminal enters the communication channel, it continues to receive the audio data sent by the sender in the next clock cycle. In this way, after receiving the confirmation information, the master terminal returns to the communication channel corresponding to the sender, so that the audio data sent by the sender can be received more effectively on the communication channel.

[0079] In some possible implementations, in order to reduce the impact of the data packet sent by the sending end on the forwarding of the audio data by the main terminal, the above step 602 can be implemented by the following steps 621 and 622 (not shown):

[0080] Step 621: Determine a difference between a third received signal strength and a second received signal strength of the master terminal signal received by the slave terminal.

[0081] The second received signal strength is the received signal strength of the sender signal received by the slave terminal. In this way, the difference can reflect the difference between the signal strength of the slave terminal receiving the data forwarded by the master terminal and the signal strength of the sender signal received by the slave terminal.

[0082] Step 622: When the difference is greater than a preset difference threshold, forward the audio data to the slave terminal through the preset channel.

[0083] Among them, the preset difference threshold can be set by the anti-channel interference capability and the anti-adjacent channel interference capability of the communication rate. For example, the signal-to-noise ratio is calculated according to the anti-channel interference capability and the anti-adjacent channel interference capability, and the preset difference threshold is set by the signal-to-noise ratio. If the difference is greater than the preset difference threshold, it means that the difference can reflect the signal strength of the data forwarded by the slave terminal received from the main terminal, which is higher than the signal strength received by the slave terminal from the transmitting end. At this time, the main terminal forwards the audio data to the slave terminal through the preset channel. In this way, although the main terminal will continue to send the next data packet after replying the confirmation information to the transmitting end, the main terminal is also forwarding the audio data at this time, and the sending end may interfere with the forwarding of the data packet by the main terminal. If the slave terminal is affected by the strong signal of the main terminal, even if the data packet sent by the transmitting end is interfered, the slave terminal can still resist the interference and the normal demodulation will not be affected. In this way, when the signal strength received by the slave terminal from the main terminal is greater than a certain range of the second received signal strength, the audio data is forwarded to the slave terminal, which can reduce the interference of the data sent by the transmitting end to the data forwarded by the slave terminal, thereby improving the success rate of receiving audio data from the terminal.

[0084] An embodiment of the present application provides an audio data transmission method, which is described below by taking the example of adaptively selecting an optimal communication path according to signal source quality.

[0085] First, the mobile phone is connected to the TWS dual-ears as follows: only the master ear is connected, the slave ear is connected to the master ear, and the slave ear is not connected to the mobile phone. The master ear and the slave ear periodically interact with each other for n seconds or milliseconds to receive the received signal strength (ReceivedSignal Strength Indication, RSSI) received by both parties. The slave ear receives RSSI_s from the mobile phone, and the master ear receives RSSI_m from the mobile phone. Compare RSSI_s and RSSI_m. If RSSI_m is greater than or equal to RSSI_s, the master ear remains unchanged; if RSSI_m is less than RSSI_s, the master-slave switch is performed, the slave ear switches to the master ear, and the master ear switches to the slave ear.

[0086] like Figure 7 As shown in Figure (a), the mobile phone 71 is connected to the earphone 72 as the master ear to establish a communication path; the earphone 72 is connected to the earphone 73 as the slave ear, the earphone 73 is not connected to the mobile phone 71, and a monitoring path is established between the earphone 73 and the mobile phone 71. If RSSI_m is less than RSSI_s, the master and slave earphones are switched, as shown in Figure (b), the earphone 71 is used as the slave ear, the earphone 7 is used as the master ear, the earphone 73 is connected to the mobile phone 71, and the earphone 72 is disconnected from the mobile phone 71 to form a monitoring path.

[0087] Secondly, the master ear establishes a communication link with the slave ear. The signal strength of the master ear receiving the slave ear packet is RSSI_f_s, and the signal strength of the slave ear receiving the master ear packet is RSSI_f_m.

[0088] Again, the mobile phone sends a packet to the master ear, and the slave ear still monitors. The slave ear monitors successfully and sends a paging packet to the master ear. After the master ear receives the page packet and successfully receives the mobile phone packet, it replies ACK to the mobile phone and indicates that it has been successfully received. Figure 8 As shown, the mobile phone 81 sends packet 0 to the master ear 82, and the master ear 82 receives it successfully (i.e., Rx succeeds). The slave ear 83 monitors "Rx succeeds" and sends page to the master ear 82. After the master ear 82 receives the page and receives it successfully, it returns ACK to the mobile phone 81. After that, the mobile phone continues to send packet 1 to the master ear, and the slave ear monitors "Rx succeeds", sends page to the master ear 82. After the master ear 82 receives the page and receives it successfully, it returns ACK to the mobile phone.

[0089] Since the master ear signal is always the best, when the master ear cannot correctly receive the data packets sent by the mobile phone, the slave ear 83 can basically not correctly monitor the data packets sent by the mobile phone. Fig. 9 The process shown realizes that the master ear receives the data packet and the slave ear also receives the data packet:

[0090] A: The master ear 91 cannot correctly receive packet 0 sent by mobile phone 90. The master ear directly returns NAK or does not respond in the next reply time slot, asking the mobile phone to retransmit.

[0091] B: Initially, slave ear 92 cannot correctly receive packet 0 sent by the mobile phone, but master ear 91 has successfully received packet 0. Slave ear 92 does not send page to master ear 91, that is, the slave ear thinks "Rx is unsuccessful". The master ear cannot receive the page packet, starts the counter, and calculates to 1, that is, counter + 1. Master ear 91 sends NAK to mobile phone 90, and the mobile phone receives NAK and retransmits packet 0 in the next clock cycle.

[0092] C: If the mobile phone initiates to retransmit packet0, and the slave ear 92 still fails to receive it successfully, the counter is incremented by 1. When the counter value reaches the preset condition M, the master ear 91 no longer returns NAK to the mobile phone 90, but returns ACK to the mobile phone 90 to indicate successful receipt.

[0093] D: After the master ear 91 sends ACK, it enters the channel negotiated with the slave ear 92 in the next clock cycle and sends the mobile phone packet0 received by the master ear 91 to the slave ear 92.

[0094] Here, after receiving ACK, mobile phone 90 sends packe1 to the master ear 91 in the next clock cycle. Since the master ear 91 will not feedback ACK to mobile phone 90 in the next clock cycle, mobile phone 90 will continue to send packe1 repeatedly until it receives ACK feedback from the master ear, and then send other data packets in the next clock cycle.

[0095] E: Since the slave ear 92 knows the counter M, after M meets the counting threshold, the slave ear 92 will enter the channel (channel) negotiated with the master ear 91 in the next clock cycle (this channel can avoid the mobile phone's next time slot transmission channel) to receive packet0 transmitted by the master ear.

[0096] F: After receiving packet0 forwarded by master ear 91, slave ear 92 replies ACK to master ear 91 to indicate normal reception.

[0097] G: If the master ear 91 forwards the message to the slave ear 92 for the first time, and the slave ear fails to receive the message and returns NAK or does not reply, the master ear continues to forward the message until the slave ear receives the message successfully.

[0098] H: After the master ear forwards successfully, both the master ear and the slave ear return to the clock cycle of the mobile phone and continue to receive packet1 from the mobile phone.

[0099] I: Forwarding mechanism can also be configured to be triggered only when the value of RSSI_f_m is greater than RSSI_s and reaches a certain range. For example, the threshold can be set according to the communication rate's ability to resist intra-channel interference or adjacent channel interference. It can effectively solve the problem of mobile phone data packets interfering with forwarded data packets when mobile phone packets are sent and forwarded at the same time.

[0100] In the embodiment of the present application, the master-slave switching is realized through RSSI judgment, and the earphone with the best signal is always kept as the master ear, so as to maintain the highest reception success rate of the master ear. Then the signal is adaptively forwarded from the master ear to the slave ear according to the conditions, which solves the problem of continuous retransmission due to poor reception of one earphone; in this way, the best transmission path is selected in real time when the TWS earphone plays mobile music, which can solve the problem of transmission failure and audio jamming caused by poor signal of one of the earphones in actual use. In particular, it solves the problem of audio jamming caused by severe attenuation of the left earphone (or right earphone) due to the mobile phone being placed in the right pocket (or left pocket).
