[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this application without creative efforts shall fall within the scope of protection of this application.

[0052] Please refer to Figure 1 , Figure 1 , which is a flowchart of a control method for a Bluetooth headset provided by an embodiment of this application.

[0053] The specific steps may include:

[0054] S101: Receive an audio data packet and determine the data bit rate corresponding to the audio data packet;

[0055] Among them, this embodiment can be applied to the processor of the Bluetooth headset (such as, a microcontroller unit MCU). When the Bluetooth headset includes a left earphone and a right earphone, this embodiment can be applied to the processors of the main earphones in the left earphone and the right earphone. The Bluetooth headset can be connected to a main control device such as a smart phone or a tablet computer, and the main control device can transmit the audio data packet to the Bluetooth headset through Bluetooth.

[0056] After receiving the audio data packet, the Bluetooth headset can perform encoding and decoding operations on the audio data packet to obtain the data bit rate corresponding to the audio data packet. Specifically, the host device can transmit multiple frames of audio data packets to the Bluetooth headset, and the Bluetooth headset determines the data bit rate of each frame of audio data packet.

[0057] As a feasible implementation, before determining the audio quality mode of the Bluetooth headset according to the data bit rate, the bit rate control mode of the Bluetooth headset can also be determined. The bit rate control mode includes a fixed bit rate mode and an adaptive bit rate mode. The bit rate for encoding and decoding in the fixed bit rate mode is a fixed value such as 990 kbps, 660 kbps, etc., and the bit rate for encoding and decoding in the adaptive bit rate mode is adaptively adjusted according to the retransmission rate. Correspondingly, if the bit rate control mode of the Bluetooth headset is the fixed bit rate mode, then enter the steps of S102 and S103 in this step: if the bit rate control mode of the Bluetooth headset is the adaptive bit rate mode, then the main control device can adjust the data bit rate according to the retransmission rate.

[0058] S102: Determine the audio quality mode of the Bluetooth headset according to the data bit rate, and determine the scanning strategy corresponding to the audio quality mode;

[0059] Among them, in this step, the current audio quality mode of the Bluetooth headset can be determined according to the data bit rate; as a feasible implementation, the audio quality mode of the Bluetooth headset can be determined according to the data bit rate of the current frame of audio data, or the audio quality mode of the Bluetooth headset can be determined according to the data bit rates of multiple recent frames of audio data.

[0060] Specifically, the audio quality mode of the Bluetooth headset can include a normal mode and a high-fidelity mode. In the normal mode, the scanning strategy is to turn on the page scan function of the Bluetooth headset; in the high-fidelity mode, the scanning strategy can be further determined in combination with the Bluetooth connection status.

[0061] S103: Turn on or off the page scan function of the Bluetooth headset according to the scanning strategy.

[0062] In this embodiment, after receiving the audio data packet, the data bit rate of the audio data packet is determined, and then the current audio quality mode of the Bluetooth headset is determined according to the data bit rate. Enabling the page scan function of the Bluetooth headset will occupy a certain data transmission bandwidth. In this embodiment, the corresponding scanning strategy is determined according to the audio quality mode, and then the page scan function of the Bluetooth headset is turned on or off according to the scanning strategy, so as to avoid the situation that the Bluetooth headset plays audio with jitter due to enabling the page scan function. Therefore, this embodiment can reduce the jitter phenomenon when the Bluetooth headset plays audio and improve the audio playback quality.

[0063] As a further introduction to Figure 1 the corresponding embodiment, the audio quality mode of the Bluetooth headset can be determined in the following way: Determine the magnitude relationship between the data bit rate of the audio data packet and the threshold bit rate; if the data bit rate of the current frame of audio data packet is less than or equal to the threshold bit rate, it is determined that the audio quality mode of the Bluetooth headset is the normal mode; if the data bit rates of consecutive N frames of audio data packets including the current frame are all greater than the threshold bit rate, it is determined that the audio quality mode of the Bluetooth headset is the high-fidelity mode.

[0064] Specifically, before determining the audio quality mode of the Bluetooth headset according to the data bit rate, the desired bit rate set by the user can also be determined, and the product of the desired bit rate and the preset coefficient a is set as the threshold bit rate; 0 < a < 1. For example, if the user's desired bit rate is 990 kbps and a is 0.8, then the threshold bit rate is 792 kbps.

[0065] As a further introduction to Figure 1 the corresponding embodiment, the above Bluetooth headset includes a main headset and a slave headset, and the scanning strategy can be determined by at least the following two methods.

[0066] Method 1: Determine the scanning strategy according to the audio quality mode and the Bluetooth connection status; wherein, the Bluetooth connection status describes whether the master earphone and the slave earphone establish a Bluetooth connection.

[0067] The above scanning strategy is specifically as follows:

[0068] If the audio quality mode is the high-fidelity mode and the master earphone and the slave earphone have established a Bluetooth connection, then generate the scanning strategy for turning off the page scan function;

[0069] If the audio quality mode is the high-fidelity mode and the master earphone and the slave earphone have not established a Bluetooth connection, then generate the scanning strategy for turning on the page scan function;

[0070] If the audio quality mode is the normal mode and the master earphone and the slave earphone have established a Bluetooth connection, then generate the scanning strategy for turning on the page scan function;

[0071] If the audio quality mode is the normal mode and the master earphone and the slave earphone have not established a Bluetooth connection, then generate the scanning strategy for turning on the page scan function;

[0072] Wherein, the data rate of the Bluetooth earphone in the normal mode is lower than the data rate of the Bluetooth earphone in the high-fidelity mode.

[0073] Method 2: Determine whether the master earphone and the slave earphone establish a Bluetooth connection; if not, then generate the scanning strategy for turning on the page scan function; if so, then determine the audio quality mode of the Bluetooth earphone according to the data rate, and determine the scanning strategy corresponding to the audio quality mode according to the following rules: if the audio quality mode is the high-fidelity mode, then generate the scanning strategy for turning off the page scan function; if the audio quality mode is the normal mode, then generate the scanning strategy for turning on the page scan function; wherein, the data rate of the Bluetooth earphone in the normal mode is lower than the data rate of the Bluetooth earphone in the high-fidelity mode.

[0074] The following uses examples in actual applications to illustrate the process described in the above embodiments.

[0075] TWS earphones can be connected to two mobile phones simultaneously, while maintaining three ACL links: one ACL link for the master and slave earphones, and one ACL link for each of the two mobile phones. During normal operations, BLE broadcasts are also performed to adapt some features to the mobile phones. The bitrate of the audio data packets received by the Bluetooth earphones is determined by the mobile phone. There is no such parameter information during the A2DP (Advanced Audio Distribution Profile) process, and the mobile phone can dynamically adjust the bitrate during playback. Usually, the mobile phone can set the bitrate to 990 kbps, 660 kbps, 330 kbps, or an adaptive bitrate. The first three bitrates are fixed bitrates, and the adaptive bitrate is the bitrate adjusted by the mobile phone according to the retransmission rate in a timely manner.

[0076] The bandwidth of the Bluetooth earphones themselves is limited. While maintaining dual connections and performing BLE broadcasts, the bandwidth available for audio data transmission is fixed. In this scenario, it is basically easy to experience stuttering during high-definition audio encoding and decoding, especially at a bitrate of 990 kbps, and there are basically no scenarios where it can be used. In the dual-connection scenario, a slight interference at a bitrate of 660 kbps will cause stuttering, seriously affecting the user experience.

[0077] To solve the above stuttering phenomenon in TWS earphones, the embodiments of this application provide a solution to reduce stuttering during high-definition audio encoding and decoding in the music service state. In this solution, during the process of providing high-quality audio at a high bitrate, the scanning strategy is adjusted in a timely manner to reduce the occurrence of stuttering, thereby greatly improving the user experience.

[0078] In the high-fidelity audio encoding and decoding music playback scenario, the TWS earphones can obtain the data bitrate corresponding to the audio data packet during the unpacking process of each frame of the audio data packet. If the data bitrate is lower than the threshold bitrate Threshold (such as 600 kbps, which can be adjusted according to actual requirements), it is determined that the current mode is the normal mode. When 50 consecutive frames are greater than the threshold bitrate, it is determined that the current mode is the high-fidelity (HD) mode. When the TWS earphones detect a switch from the normal mode to the high-fidelity mode, or from the high-fidelity mode to the normal mode, the scanning strategy (i.e., the page scan strategy) is triggered. For the adaptive bitrate scenario, the mobile phone will adjust the bitrate in real time, and there will basically be no stuttering. Most of the stuttering occurs in the fixed bitrate scenario, such as 660 kbps or 990 kbps. By continuously detecting that 50 consecutive frames are greater than the bitrate threshold, it is determined that the current is a continuous high-bitrate scenario, and an updated scanning strategy needs to be triggered.

[0079] After the Page scan function is enabled, the TWS earphones need to reserve a certain time slot to monitor the page data packet (reconnection request). When the Page scan function is enabled, the mobile phone or the paired earphone can successfully reconnect. In the scenario where Page scan is disabled, the paired earphone (i.e., the other TWS earphone) or the mobile phone cannot reconnect successfully. Add a policy to the Page scan policy: when the earphone is in the high-fidelity mode and a Bluetooth connection has been established, turn off the Page scan function. This policy does not affect the master-slave reconnection: when no Bluetooth connection is established between the master earphone and the slave earphone, Page scan is enabled, and the master earphone and the slave earphone can successfully reconnect. In the above process, when a Bluetooth connection has been established between the master earphone and the slave earphone and the Page scan function is turned off in the high-fidelity mode, more bandwidth is reserved for the downlink audio data transmission in this scenario, and other mobile phones cannot connect to the earphone, greatly reducing the jitter in the high bit rate and optimizing the user experience.

[0080] Please refer to Figure 2 , Figure 2 which is a flowchart for determining an audio quality mode provided by an embodiment of the present application, and the process shown is as follows:

[0081] S201: Play music;

[0082] S202: Set the audio quality mode to the normal mode and clear the counter;

[0083] S203: Obtain the bit rate;

[0084] S204: Determine whether the bit rate is less than or equal to the bit rate threshold; if so, go to S205; if not, go to S207;

[0085] S205: Determine whether the current mode is the normal mode; if so, go to S203; if not, go to S206;

[0086] S206: Set the audio quality mode to the normal mode and clear the counter;

[0087] S207: Determine whether the current mode is the high-fidelity mode; if so, go to S203; if not, go to S208;

[0088] S208: Increment the value of the counter by 1;

[0089] S209: Determine whether the value of the counter exceeds 50; if so, go to S210; if not, go to S203;

[0090] S210: Set the audio quality mode to the high-fidelity mode and clear the counter.

[0091] Please refer to Figure 3, Figure 3 This is a schematic diagram of the principle for determining a scanning strategy provided by an embodiment of the present application. When the audio quality mode switches from the normal mode to the high-fidelity mode, or from the normal mode to the high-fidelity mode, the scanning strategy is triggered. If the TWS earphone is in the high-fidelity mode and a Bluetooth connection has been established, the page scan function is turned off; if the TWS earphone is in the high-fidelity mode and no Bluetooth connection has been established, the page scan function is turned on; if the TWS earphone is in the normal mode and a Bluetooth connection has been established, the page scan function is turned on; if the TWS earphone is in the normal mode and no Bluetooth connection has been established, the page scan function is turned on.

[0092] In the process of providing high-quality audio at a high bit rate in the above embodiment, the scanning strategy is adjusted in a timely manner to reduce the occurrence of stuttering. After introducing this solution, the data retransmission rate in the high-bit-rate scenario is reduced from 10% to 6%. There is basically no stuttering in the general usage scenario with a single ACL connection of 990 kbps, greatly improving the user experience.
