[0071] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0072] Currently, many terminal devices can transmit audio to Bluetooth headsets through the Bluetooth audio transmission model protocol (Advanced Audio Distribution Profile, A2DP) to play audio. Bluetooth headsets support connecting to multiple Bluetooth devices at the same time. Each connection will maintain a Bluetooth connection and send and receive data. These Bluetooth connections occupy a certain amount of Bluetooth bandwidth. However, the Bluetooth bandwidth is limited. When the Bluetooth audio data stream bit rate is high and environmental interference causes retransmission, it may cause jamming. Generally, the impact is small when a Bluetooth headset is connected to two terminals at the same time. If three terminal devices are connected at the same time, it will affect audio transmission and cause jamming. Therefore, when the user configures a Bluetooth headset and turns on high-bitrate audio codec, the headset will actively limit the maximum number of connections, for example, connecting to a maximum of two devices. However, when a user has multiple Bluetooth devices, how to allow users to obtain better convenience and experience is an urgent problem to be solved today.

[0073] Based on at least one of the above technical problems, the present application provides a Bluetooth communication method, which is applied to a Bluetooth headset, and the Bluetooth headset establishes Bluetooth connections with a first electronic device, a second electronic device, and a third electronic device respectively; the method includes: obtaining a first request of a first application in the first device, and the first request is used to apply for audio focus; wherein the second application holds the audio focus, and the second application is installed in the second device or the third device; in response to the first request, comparing the priority of the first application with the priority of the second application; if the priority of the first application is less than or equal to the priority of the second application, blocking the application of the first application; if the priority of the first application is greater than the priority of the second application, seizing the audio focus of the second application. In the Bluetooth communication method of the embodiment of the present application, the Bluetooth headset is connected to at least three electronic devices, and when there is an electronic device applying for audio focus, the priority of the application of the front device and the application of the rear device is used to determine whether to block or seize the audio focus. In this way, the connection between the Bluetooth headset and multiple devices can be realized, so that users can get a better experience.

[0074] Figure 1A schematic flow chart of a Bluetooth communication method according to an embodiment of the present application is shown. Applied to a Bluetooth headset, the Bluetooth headset establishes Bluetooth connections with a first electronic device, a second electronic device, and a third electronic device respectively. The embodiment of the present application can connect three devices at the same time through the blocking and preemption strategy of the Bluetooth connection, so that the user can get a better experience.

[0075] The electronic devices of the embodiments of the present application may include personal computers, laptop computers, tablet computers, mobile phones, VR glasses and other portable electronic devices.

[0076] like Figure 1 As shown, the Bluetooth communication method 100 according to the embodiment of the present application may include the following steps S101, S102, S103 and S104:

[0077] In step S101, a first request of a first application in the first device is obtained, where the first request is used to apply for audio focus.

[0078] Many terminal devices can play audio by transmitting audio to Bluetooth headsets through the Bluetooth audio transmission model protocol (Advanced Audio Distribution Profile, A2DP). When two or more applications output audio streams to play audio at the same time, the system will mix all audio streams together. Therefore, in order to avoid all audio applications playing at the same time, "audio focus" is designed, that is, only one application can obtain audio focus at a time. When an application needs to output audio, it needs to request audio focus, and after obtaining focus, it can play sound. However, obtaining audio focus does not mean that the application can hold it until the playback is completed. Other applications can also request focus, thereby preempting the audio focus held by the application.

[0079] In one example, a second application holds the audio focus, and the second application is installed on the second device or the third device.

[0080] In step S102, in response to the first request, the priority of the first application is compared with the priority of the second application.

[0081] The application of the electronic device may include a telephone application or a media player application, and the priority of the telephone application is greater than the priority of the media player application.

[0082] In step S103, when the priority of the first application is less than or equal to the priority of the second application, the application of the first application is blocked.

[0083] As shown in FIG2(a), it is a schematic diagram of the audio focus of the media audio being on the second application of the second electronic device. The Bluetooth headset receives an audio stream (STREAMING) based on the Bluetooth audio transmission model protocol (Advanced Audio Distribution Profile, A2DP) sent by the second electronic device. The Bluetooth audio transmission model protocol (A2DP) can use the chip in the headset to stack data to achieve high-definition sound.

[0084] As shown in Figure 2(b), it is a schematic diagram of the Bluetooth headset blocking the first application's request to obtain audio focus. When the first application of the first electronic device sends a request to obtain audio focus to the Bluetooth headset, since the priority of the first application is less than or equal to the second application of the second electronic device, the Bluetooth headset rejects the request of the first application (REJECT REQUEST), but still receives the Bluetooth audio transmission model protocol audio stream (A2DPSTREAMING) sent by the second application of the second electronic device, and the audio focus is still on the second application of the second electronic device.

[0085] In step S104, when the priority of the first application is greater than the priority of the second application, the audio focus of the second application is seized.

[0086] In one embodiment of the present application, Figure 3 As shown, when the priority of the first application is greater than the priority of the second application, after seizing the audio focus of the second application, the method further includes step S301:

[0087] In step S301, audio data of the first application is played based on the audio focus.

[0088] The audio data of the second application is paused; or the audio data of the second application is played in another playback mode, wherein the another playback mode includes the default preferred playback mode of the electronic device to which the second application belongs.

[0089] In one example, if Figure 4 As shown, it is a schematic diagram of media audio grabbing media audio focus according to an embodiment of the present application. Figure 4The second electronic device in the is in the media audio playback state, and the headphone audio focus is on the second electronic device. When the first application of the first electronic device initiates media audio, if the Bluetooth headset is configured as the media audio preempts the media audio option, the Bluetooth headset will issue a Bluetooth command to pause (PAUSE) the audio playback of the second application of the second electronic device (front device), so that the audio transmission model protocol of the second electronic device is in a suspended state (A2DP SUSPEND), and then switch the audio focus to the first application audio of the first electronic device (rear device), and the Bluetooth headset receives the audio transmission model protocol audio stream (A2DP STREAMING) of the first application of the first electronic device (rear device) to play the audio. Of course, if the Bluetooth headset is configured as the media audio does not preempt the media audio option, the headset will reject the Bluetooth playback request of the first electronic device (rear device) or disconnect the Bluetooth audio transmission model protocol (A2DP), so that the first electronic device (rear device) does not play or uses the speaker of the first electronic device to play the media audio.

[0090] In other embodiments, some enhanced options may also be configured in the Bluetooth headset, for example, the first electronic device seizes the audio focus of the second electronic device, and then when the first electronic device (rear device) pauses playing the media audio, the Bluetooth headset resumes playing the audio of the second electronic device (front device).

[0091] In another example, as shown in FIG5(a), it is a schematic diagram that the audio focus of the telephone audio is on the second electronic device. The Bluetooth headset receives the audio stream (STREAMING) of the connection-oriented synchronous transmission mode (Synchronous Connection Oriented, SCO) sent by the second electronic device. The audio stream (SCO STREAMING) of the connection-oriented synchronous transmission mode can provide lower latency and higher transmission rate.

[0092] As shown in Figure 5(b), it is a schematic diagram of the telephone audio preempting the audio focus of the telephone audio of an embodiment of the present application. The second electronic device is in the telephone state, and the headset audio focus is on the second electronic device (front device). When the first electronic device (rear device) initiates the telephone audio, if it is configured as the telephone audio preempts the telephone audio option, the Bluetooth headset will issue a Bluetooth instruction to hold (HOLD) the telephone state of the second electronic device (front device), for example, the synchronous transmission mode audio stream (SCO STREAMING) received by the second electronic device is in the hold state (HOLD), and then the audio focus is switched to the audio of the first electronic device (rear device), and the synchronous transmission mode audio stream (SCO STREAMING) of the first electronic device is received to play the audio, and the Bluetooth hands-free protocol (Hands-Free, HFP) of the third electronic device is in the disconnected state (DISCONNECTED). If it is configured that the telephone audio does not preempt the telephone audio option, the Bluetooth headset will reject the Bluetooth audio channel establishment instruction of the first electronic device (rear device), so that the first electronic device (rear device) does not play or uses the speaker of the first electronic device to play the telephone audio.

[0093] In other embodiments, some enhanced options can also be configured in the Bluetooth headset. For example, the first electronic device seizes the audio focus of the second electronic device. When the first electronic device (the rear device) hangs up the phone, the Bluetooth headset will actively initiate the establishment of a telephone audio channel to restore the telephone audio of the second electronic device (the front device) that has lost the audio focus.

[0094] In another example, Figure 6As shown, it is a schematic diagram of telephone audio preempting media audio in an embodiment of the present application. In the connection structure of the Bluetooth headset and the first electronic device, the second electronic device and the third electronic device as shown in Figure 2 (a), since the priority of telephone audio is higher than that of media audio, the telephone audio preempts the media audio option by default. The second electronic device is in the media audio state, at which time the Bluetooth headset receives the audio stream (STREAMING) based on the Bluetooth audio transmission model protocol (Advanced Audio Distribution Profile, A2DP) sent by the second electronic device. The audio focus of the Bluetooth headset is on the second electronic device. When the first electronic device initiates telephone audio, the Bluetooth headset will issue a Bluetooth command to pause transmission (PAUSE) of the audio stream (A2DP STREAMING) based on the Bluetooth audio transmission model protocol of the second electronic device (front device), and then switch the audio focus to the synchronous transmission mode audio stream (SCO STREAMING) of the first electronic device (rear device), and the Bluetooth hands-free protocol (Hands-Free, HFP) of the third electronic device is in a disconnected state (DISCONNECTED). Enhanced options can also be configured, for example, the first electronic device seizes the focus audio of the second electronic device. After the first electronic device (front device) hangs up the call, the Bluetooth headset will restore the media audio of the device that has lost focus due to the first electronic device (front device).

[0095] In one embodiment of the present application, Figure 7 As shown, after playing the audio data of the first application based on the audio focus, the method further includes step S801:

[0096] In step S701, after the audio data of the first application is played, the audio focus is switched back to the second application.

[0097] As shown above, some enhanced options can be configured in the Bluetooth headset, for example, the first electronic device seizes the audio focus of the second electronic device. When the first electronic device (the rear device) hangs up the phone, the Bluetooth headset will actively initiate the establishment of a phone audio channel and restore the phone audio of the second electronic device (the front device) that has lost the audio focus. For another example, the first electronic device seizes the audio focus of the second electronic device, and then when the first electronic device (the rear device) pauses playing the media audio, the Bluetooth headset resumes playing the audio of the second electronic device (the front device).

[0098] In one embodiment of the present application, Figure 8 , which is a schematic flow chart of a process of switching a Bluetooth headset from a non-connection mode to a connection mode. The process 800 of switching a Bluetooth headset from a non-connection mode to a connection mode includes steps S801 and S802:

[0099] In step S801, when the Bluetooth headset is switched from the non-connection mode to the connection mode, detecting whether the Bluetooth headset has established Bluetooth connections with the first electronic device, the second electronic device, and the third electronic device;

[0100] In step S802, when the Bluetooth headset has not established a Bluetooth connection with any one of the first electronic device, the second electronic device and the third electronic device, the Bluetooth headset is enabled to establish a Bluetooth connection with the electronic device with which the connection has not been established.

[0101] In one embodiment of the present application, the Bluetooth headset comprises a true wireless stereo headset, and the true wireless stereo headset comprises a first earplug and a second earplug. Fig. 9 The figure shows a schematic diagram of establishing a Bluetooth connection between a true wireless stereo headset and the first electronic device, the second electronic device, and the third electronic device. In one example, the first Bluetooth connection includes an asynchronous Bluetooth link connection (ACL); the second Bluetooth connection includes an intelligent Bluetooth retransmission technology (IBRT) link connection.

[0102] Here, the Bluetooth Asynchronous Link Connection (ACL) is an asynchronous connectionless link, which is mainly used for packet data transmission. Bluetooth operation commands are transmitted through this link. The Bluetooth Asynchronous Link Connection (ACL) is a packet-oriented connection. It supports both symmetric and asymmetric transmission traffic, and also supports broadcast information. Here, the Bluetooth Asynchronous Link Connection (ACL) is mainly used for transmission scenarios where real-time requirements are not very high, such as listening to music. Intelligent Bluetooth Transmission Technology (IBRT) is an in-ear transmission technology that can support left and right simultaneous sound, and is extremely comfortable to use with one ear. In-ear transmission technology can greatly reduce the delay problem of the left and right ears, and truly achieve split simultaneous sound. At the same time, the left and right ears are used alternately, which can avoid the discomfort caused by long-term wearing of one side, increase the degree of use, and effectively protect our hearing.

[0103] like Fig.10 As shown, the method further includes step S1001, step S1002 and step S1003:

[0104] In step S1001, the first earplug establishes a first Bluetooth connection with the second application to receive and play audio data of the second application;

[0105] In step S1002, the first earplug establishes a True Wireless Stereo (TWS) connection with the second earplug;

[0106] In step S1003, the first earbud sends connection parameters of the first Bluetooth connection to the second earbud through the true wireless stereo (TWS) connection, so that the second earbud establishes a second Bluetooth connection with the second application based on the connection parameters of the first Bluetooth connection.

[0107] The second earplug monitors the second application through the second Bluetooth connection, and receives and plays the audio data of the second application.

[0108] True Wireless Stereo (TWS) is a technology used in audio devices, especially headphones. It allows users to achieve wireless transmission of sound without cables, greatly improving the convenience and freedom of use. True Wireless Stereo (TWS) headphones usually contain two independent earbuds, each of which can communicate directly with the device to achieve wireless separation of left and right channels, providing a more immersive listening experience. The working principle of True Wireless Stereo (TWS) mainly includes two parts: first, the mobile phone or other audio device connects to the main headset via Bluetooth; then, the main headset quickly connects to the secondary headset wirelessly to achieve binaural stereo effect. In this process, the Bluetooth protocol ensures efficient and stable transmission of audio signals. With the continuous advancement of Bluetooth technology, the connection stability and sound quality performance of TWS headphones have also been significantly improved.

[0109] In one example, the first earplug of the true wireless stereo headset stores Bluetooth connection information with any electronic device. Fig.11 , which is a schematic flow chart of a true wireless stereo headset reconnection process 1100 according to an embodiment of the present application. The true wireless stereo headset reconnection process 1100 includes step S1101, step S1102 and step S1103:

[0110] In step S1101, when the true wireless stereo headset is switched from a non-connection mode to a connection mode, establishing a true wireless stereo (TWS) connection between the first earplug and the second earplug;

[0111] In step S1102, it is detected whether the true wireless stereo headset has established a Bluetooth connection with the first electronic device, the second electronic device, and the third electronic device; if not, step S1003 is executed; otherwise, the process ends;

[0112] In step S1103, when the true wireless stereo headset has not established a Bluetooth connection with any of the first electronic device, the second electronic device and the third electronic device, based on the Bluetooth connection information between the first earbud and any of the electronic devices stored in the first earbud, an asynchronous link connection (ACL) is established between the first earbud and the electronic device with which the connection has not been established, and an intelligent Bluetooth transmission technology (IBRT) link connection is established between the second earbud and the electronic device with which the connection has not been established.

[0113] In another embodiment of the present application, the Bluetooth headset further comprises a stereo headset, the stereo headset comprises a Bluetooth module and a distribution module, and the Bluetooth module is used to connect to an electronic device. Fig.12 FIG. 1 is a schematic flow chart of a stereo headset reconnection process 1200 according to an embodiment of the present application. The stereo headset reconnection process 1200 includes step S1201 and step S1202:

[0114] In step S1201, the Bluetooth module receives audio data of the second application;

[0115] In step S1202, the distribution module distributes the audio data of the second application to the left channel device and the right channel device of the stereo headset.

[0116] In one example, if Fig.13 As shown, Fig.13 , which is a schematic flow chart of a Bluetooth module reconnection process 1300 of a stereo headset according to an embodiment of the present application. The method further includes step S1301 and step S1302:
