This application claims the priority of the Chinese patent application filed with the State Intellectual Property Office on October 20, 2022, with application number 202211288799.X, and invention name “A method for processing audio services, an electronic device, and a computer storage medium”, as well as the priority of the Chinese patent application filed with the State Intellectual Property Office on October 20, 2022, with application number 202211289367.0, and invention name “A method for processing audio services, an electronic device, and a computer storage medium”, the entire contents of which are incorporated by reference in this application.

Technical Field

The present application relates to the field of communication technology, and in particular to an audio service processing method, electronic equipment and computer storage medium.

Background technique

Bluetooth headsets are becoming more and more popular with users due to their portability and convenience, as they do not need to store or organize the headphone cables. The function of Bluetooth headsets is that they can establish a wireless connection with electronic devices, thereby cooperating with electronic devices to process audio services for users. For example, Bluetooth headsets can establish a wireless connection with mobile phones, and cooperate with mobile phones to play music, make/receive calls, etc. for users.

At present, users usually use multiple electronic devices, such as mobile phones, tablets, personal computers (PCs), etc. In order to facilitate work and life, Bluetooth headsets can be connected to multiple electronic devices at the same time. For example, there is a Bluetooth headset with a built-in Bluetooth audio transmission model protocol (Advanced Audio Distribution Profile, A2DP) audio device, and the A2DP audio device is used for high-definition media playback. The A2DP audio device of the headset can be connected to two electronic devices at the same time, and can automatically connect to the newly approached electronic device through the discovery connection mechanism, and randomly disconnect a previously connected electronic device to ensure that only two electronic devices are connected at the same time. For another example, there is a Bluetooth headset with two built-in audio input and output devices: a hands-free profile (HFP) for high-definition calls; an A2DP for high-definition media playback. The headset can be connected to up to three electronic devices. Specifically, as mentioned above, the A2DP audio device of the headset can be connected to two electronic devices at the same time, and the HFP device of the headset can be connected to one device.

In the prior art, a Bluetooth headset can only be used as an audio output device for an audio service. If a service conflict occurs in a Bluetooth headset, for example, multiple electronic devices initiate a request to the Bluetooth headset to process an audio service, or the Bluetooth headset is processing an audio service sent by an electronic device 1 connected to it, and at this time, it receives a request to process an audio service sent by another electronic device. Because the Bluetooth headset can only be used as an audio output device for an audio service, the audio service of another electronic device is put on hold, and the audio service sent by other electronic devices cannot be completed in time. If the audio service sent by other electronic devices is more important, the Bluetooth headset cannot complete the more important audio service in time, and the user experience is poor.

Summary of the invention

The present invention provides an audio service processing method, an electronic device and a computer storage medium for decoding In the prior art, the Bluetooth headset can only be used as an audio output device for an audio service. If a service conflict occurs in the Bluetooth headset, the Bluetooth headset can only be used as an audio output device for an audio service, and the audio service of another electronic device will be put on hold, and the audio service sent by other electronic devices cannot be completed in time. If the audio service sent by other electronic devices is more important, the Bluetooth headset cannot complete the more important audio service in time, resulting in a poor user experience.

To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

In a first aspect, a method for processing an audio service is provided, the method comprising: a first electronic device and a second electronic device both establish a wireless communication channel with a Bluetooth headset; the first electronic device uses the Bluetooth headset to process a first audio service; after the second electronic device detects the second audio service, it determines whether the service priority of the second audio service is greater than the service priority of the first audio service; if the service priority of the second audio service is greater than the service priority of the first audio service, the second electronic device requests the Bluetooth headset to suspend processing of the first audio service, and uses the Bluetooth headset to process the second audio service.

In this solution, the electronic device can control the Bluetooth headset to process more important audio services according to the pre-set service priority, thereby improving the user experience.

In a possible implementation of the first aspect, requesting a Bluetooth headset to suspend processing of a first audio service and using the Bluetooth headset to process a second audio service includes: the second electronic device sends a service suspension instruction to the first electronic device through the Bluetooth headset; the first electronic device receives the service suspension instruction and stops sending audio data of the first audio service to the Bluetooth headset; the second electronic device sends audio data of the second audio service to the Bluetooth headset; the Bluetooth headset receives audio data of the second audio service and processes the second audio service. In this implementation, the second electronic device can instruct the first electronic device to stop sending audio data of the first audio service to the Bluetooth headset and instruct the Bluetooth headset to suspend processing of the first audio service of the first electronic device by sending a service suspension instruction to the first electronic device.

In a possible implementation of the first aspect, before the second electronic device requests the Bluetooth headset to suspend processing of the first audio service and uses the Bluetooth headset to process the second audio service, the method further includes: the first electronic device indicates the service priority of the first audio service to the second electronic device through the Bluetooth headset. After the first electronic device synchronizes the priority of the first audio service to the second electronic device, after the second electronic device detects the second audio service, it can determine whether the service priority of the second audio service is greater than the service priority of the first audio service, and after determining that the service priority of the second audio service is greater than the service priority of the first audio service, it seizes the right to use the Bluetooth headset, requests the Bluetooth headset to suspend processing of the first audio service, and starts processing the second audio service.

In a possible implementation of the first aspect, the service pause instruction is used to indicate the service priority of the second audio service; the first electronic device receives the service pause instruction and stops sending audio data of the first audio service to the Bluetooth headset, including: the first electronic device receives the service pause instruction, and if the service priority of the second audio service indicated by the service pause instruction is greater than the service priority of the first audio service, stops sending audio data of the first audio service to the Bluetooth headset.

In this solution, after receiving the service suspension instruction, the first electronic device will reconfirm the service priorities of the second audio service and the first audio service, so as to further ensure the accuracy of the first electronic device in executing the service suspension instruction.

In a possible implementation manner of the first aspect, after requesting the Bluetooth headset to suspend processing of the first audio service and using the Bluetooth headset to process the second audio service, the method further includes: the first electronic device using an audio component of the first electronic device to process the first audio service.

In this solution, after the Bluetooth headset suspends processing of the first audio service, the first electronic device can also automatically process the first audio service to be processed, thereby improving the completion rate of the audio service.

In a possible implementation of the first aspect, the audio services processed by the Bluetooth headset include call services, multimedia services, and notification services; wherein the service priority of the call service is greater than the service priority of the multimedia service, and the service priority of the multimedia service is greater than the service priority of the notification service.

In a possible implementation of the first aspect, after using the Bluetooth headset to process the second audio service, the method also includes: the first electronic device displays a first prompt message after the Bluetooth headset suspends processing the first audio service; wherein the first prompt message is used to request the user to determine whether the first electronic device resumes using the Bluetooth headset to process the first audio service; the first electronic device responds to the user's first operation on the first prompt message, requests the Bluetooth headset to suspend processing the second audio service, and uses the Bluetooth headset to process the first audio service; wherein the first operation is used to trigger the first electronic device to resume using the Bluetooth headset to process the first audio service.

In this solution, the audio service of an electronic device with a higher service priority is not simply decided according to the service priority order set for the audio service. After pausing an audio service, the user can decide whether to continue the audio service. Afterwards, the user can choose whether to resume the preempted audio service according to his/her wishes. In this way, the flexibility of audio service switching is improved, and the user experience is improved.

In a possible implementation of the first aspect, the method also includes: if the service priority of the second audio service is equal to the service priority of the first audio service, the second electronic device displays a second prompt message; wherein the second prompt message is used to request the user to determine whether the second electronic device should preempt the Bluetooth headset to process the second audio service; the second electronic device responds to the user's third operation on the second prompt message, requests the Bluetooth headset to suspend processing the first audio service, and uses the Bluetooth headset to process the second audio service; wherein the third operation is used to trigger the second electronic device to preempt the Bluetooth headset to process the second audio service.

In this solution, when audio services that simultaneously require the right to use the Bluetooth headset are at the same service priority, the second electronic device that initiates the audio service later can display a prompt message requesting the user to determine whether the second electronic device should preempt the Bluetooth headset to process the second audio service. In this way, the user can decide whether to process the second audio service initiated later first based on his or her wishes, thereby improving the user experience.

In a possible implementation of the first aspect, the first electronic device, in response to a user's first operation on a first prompt message, requests the Bluetooth headset to suspend processing of a second audio service, and uses the Bluetooth headset to process the first audio service, including: if the first electronic device receives the user's first operation on the first prompt message within a first preset time period, the first electronic device, in response to the first operation, requests the Bluetooth headset to suspend processing of the second audio service, and uses the Bluetooth headset to process the first audio service.

In this solution, the display time of the first prompt information needs to be controlled within a certain time. If the user's first operation on the first prompt information is detected within the control time, the second electronic device resumes the originally suspended audio service. In this way, the efficiency of the second electronic device in resuming the originally suspended audio service is improved.

In this solution, the display time of the first prompt information needs to be controlled within a certain time. If the user's first operation on the first prompt information is detected within the control time, the second electronic device resumes the originally suspended audio service, thereby improving the efficiency of the second electronic device in resuming the originally suspended audio service. After the Bluetooth headset processes the second audio service, the first electronic device can automatically resume using the Bluetooth headset to process the first audio service without user operation, thereby improving the user experience.

In a possible implementation of the first aspect, the method also includes: the first electronic device responds to the user's second operation on the first prompt information, and if the second electronic device completes processing the second audio service using the Bluetooth headset within a second preset time period, the first electronic device uses the Bluetooth headset to process the first audio service after the Bluetooth headset completes processing the second audio service; or, the first electronic device responds to the user's second operation on the first prompt information, and if the second electronic device suspends processing the second audio service using the Bluetooth headset within the second preset time period, the first electronic device uses the Bluetooth headset to process the first audio service after the Bluetooth headset suspends processing the second audio service; wherein the second operation is used to trigger the first electronic device to not resume processing the first audio service using the Bluetooth headset.

Detailed ways

The illustrative embodiments of the present application include, but are not limited to, an audio service processing method, an audio device, and a storage medium.

The following describes the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the described embodiments are only embodiments of a part of the present application, rather than all embodiments. It is known to those skilled in the art that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

As described in the background technology above, if a service conflict occurs in a Bluetooth headset, the Bluetooth headset can only be used as an audio output device for an audio service, and the audio service of another electronic device will be put on hold, and the audio service sent by other electronic devices cannot be completed in time. If the audio service sent by other electronic devices is more important, the Bluetooth headset cannot complete the more important audio service in time, and the user experience is poor.

In order to solve the above technical problems, an embodiment of the present application provides an audio service processing method, which includes: electronic device 1 and electronic device 2 both establish wireless communication channels with a Bluetooth headset. If electronic device 1 is using a Bluetooth headset to process audio service 1, at this time, after electronic device 2 detects audio service 2, it will first determine whether the service priority of audio service 2 is greater than or equal to the service priority of audio service 1. If electronic device 2 determines that the service priority of audio service 2 is greater than or equal to the service priority of audio service 1, it will request the Bluetooth headset to suspend processing of audio service 1 and use the Bluetooth headset to process audio service 2. As a result, the Bluetooth headset will suspend processing of audio service 1 and process audio service 2.

In the embodiment of the present application, different audio services may correspond to different priorities. Audio services with higher priorities are usually important and critical audio services. Audio services with higher priorities can be processed preferentially by Bluetooth headsets. Exemplarily, audio services may include multiple types, for example, audio services may include call services, multimedia services, notification services, etc. Call services may include playing the voice data of the other end for the user in scenarios such as phone calls (including incoming and outgoing calls), video calls, audio calls, voice messages, games or voice assistants, or collecting the user's voice data and sending it to the other end, as well as playing incoming call ringtones, etc. Multimedia services may include playing music, videos, recordings, background music of games, text-to-speech sounds, etc. Notification services may include playing SMS prompts, push notification prompts, alarm ringtones, system sounds (such as sounds when adjusting the volume, shutter sounds when shooting, etc.). The priorities of notification services, multimedia services, and call services increase in sequence. In other embodiments, audio services may include more types, which are not specifically limited here. Among them, the priority of the audio service may be pre-set or actively set by the user, which is not specifically limited here. For example, the service priority of the call service is higher than the service priority of the multimedia service, and the service priority of the multimedia service is higher than the service priority of the notification service.

In this way, the electronic device can control the Bluetooth headset to process more important audio services according to the pre-set service priority, thereby improving the user experience.

For example, the electronic devices (such as electronic device 1 and electronic device 2) in the embodiments of the present application may be mobile phones, media players (such as MP3, MP4, etc.), tablet computers, laptop computers, ultra-mobile personal computers (UMPC), personal digital assistants (PDA), televisions, smart watches, and other devices. The embodiments of the present application do not impose any special restrictions on the specific form of the electronic devices. Electronic device 1 is the first electronic device, and electronic device 2 is the second electronic device.

The embodiments of the present application are described by taking the electronic device 1 as a tablet (such as the tablet 300) as an example. Fig. 1 shows a schematic diagram of the structure of a tablet 300 according to some embodiments of the present application.

As shown in FIG1 , the tablet 300 may include a processor 310, an external memory interface 320, an internal memory 321, a universal serial bus (USB) interface 330, a charging management module 340, a power management module 341, a battery 342, an antenna 1, an antenna 2, a mobile communication module 350, a wireless communication module 360, an audio module 370, a speaker 370A, a receiver 370B, a microphone 370C, an earphone interface 370D, a sensor module 380, a button 390, a motor 391, an indicator 392, a camera 393, a display screen (touch screen) 394, and a subscriber identification module (SIM) card interface 395, etc.

Among them, the above-mentioned sensor module 380 may include sensors such as pressure sensor, gyroscope sensor, air pressure sensor, magnetic sensor, acceleration sensor, distance sensor, proximity light sensor, fingerprint sensor, temperature sensor, touch sensor, ambient light sensor and bone conduction sensor.

It is understood that the structure shown in this embodiment does not constitute a specific limitation on the tablet 300. In other embodiments, the tablet 300 may include more or fewer components than shown in the figure, or combine some components, or separate some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

The processor 310 may include one or more processing units, for example, the processor 310 may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and/or a neural-network processing unit (NPU), etc. Different processing units may be independent devices or integrated into one or more processors.

The controller may be the nerve center and command center of the tablet 300. The controller may generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions.

A memory may also be provided in the processor 310 for storing instructions and data. In some embodiments, the memory in the processor 310 is a cache memory. The memory may store instructions or data that the processor 310 has just used or cyclically used. If the processor 310 needs to use the instruction or data again, it may be directly called from the memory. Repeated access is avoided, and the waiting time of the processor 310 is reduced, thereby improving the efficiency of the system. In the embodiment of the present application, both the electronic device 1 and the electronic device 2 establish a wireless communication channel with the Bluetooth headset. If the electronic device 1 is using the Bluetooth headset to process the audio service 1, at this time, after the processor 310 detects the audio service 2 again, it will first determine whether the service priority of the audio service 2 is greater than or equal to the service priority of the audio service 1. If the processor 310 determines that the service priority of the audio service 2 is greater than or equal to the service priority of the audio service 1, it will request the Bluetooth headset to suspend the processing of the audio service 1, and use the Bluetooth headset to process the audio service 2. Then, the Bluetooth headset will suspend the processing of the audio service 1 and process the audio service 2.

In some embodiments, the processor 310 may include one or more interfaces. The interfaces may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver/transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input/output (GPIO) interface, a subscriber identity module (Subscriber Identity Module) interface, a general-purpose input/output (GPIO ... module, SIM) interface, and/or universal serial bus (USB) interface, etc.

It is understandable that the interface connection relationship between the modules shown in this embodiment is only a schematic illustration and does not constitute a structural limitation on the tablet 300. In other embodiments, the tablet 300 may also adopt different interface connection methods in the above embodiments, or a combination of multiple interface connection methods.

The charging management module 340 is used to receive charging input from a charger. The charger can be a wireless charger or a wired charger. While the charging management module 340 is charging the battery 342, it can also power the electronic device through the power management module 341.

The power management module 341 is used to connect the battery 342, the charging management module 340 and the processor 310. The power management module 341 receives input from the battery 342 and/or the charging management module 340, and supplies power to the processor 310, the internal memory 321, the external memory, the display screen 394, the camera 393, and the wireless communication module 360. In some embodiments, the power management module 341 and the charging management module 340 can also be set in the same device.

The wireless communication function of the tablet 300 can be implemented through antenna 1, antenna 2, mobile communication module 350, wireless communication module 360, modem processor and baseband processor. In some embodiments, the antenna 1 of the tablet 300 is coupled with the mobile communication module 350, and the antenna 2 is coupled with the wireless communication module 360, so that the tablet 300 can communicate with the network and other devices through wireless communication technology.

Antenna 1 and antenna 2 are used to transmit and receive electromagnetic wave signals. Each antenna in the flat panel 300 can be used to cover a single or multiple communication frequency bands. Different antennas can also be reused to improve the utilization of the antennas. For example, antenna 1 can be reused as a diversity antenna for a wireless local area network.

It can be understood that the structure of the mobile phone 200 may be the same as or different from that of the tablet 300, and will not be described in detail here.

For example, in the embodiment of the present application, the method of the embodiment of the present application is introduced by taking the electronic device 1 (i.e., the first electronic device) as a mobile phone 200, the electronic device 2 (i.e., the second electronic device) as a tablet 300, and the Bluetooth headset as a Bluetooth headset 100 as an example. Among them, the audio service 1 is the first audio service, and the audio service 2 is the second audio service.

For example, Fig. 2 shows a schematic diagram of an application scenario of an audio service processing method according to some embodiments of the present application. Fig. 3 shows a schematic diagram of an application scenario of an audio service processing method according to some embodiments of the present application.

As shown in FIG2 , the application scenario includes a mobile phone 200, a tablet 300, a user, and a Bluetooth headset worn by the user. 100. Both the mobile phone 200 and the tablet 300 establish wireless communication channels with the Bluetooth headset 100. Among them, the mobile phone 200 uses the Bluetooth headset 100 to process audio service 1, for example, using the Bluetooth headset 100 to play music. Afterwards, as shown in Figure 3, the tablet 300 may detect music service 2, for example, the tablet 300 may need to use the Bluetooth headset 100 to play music. At this time, the service priority of audio service 2 may be greater than or equal to the service priority of audio service 1. For example, when audio service 2 is playing music and audio service 1 is playing music, the service priority of audio service 2 is equal to the service priority of audio service 1. The subsequent embodiments of the present application will introduce the priority of each audio service, which will not be repeated here.

When the tablet 300 determines that the service priority of audio service 2 is greater than or equal to the service priority of audio service 1, the tablet 300 may request the Bluetooth headset 100 to suspend processing of audio service 1 (such as playing music of the mobile phone 200) and use the Bluetooth headset 100 to process audio service 2 (such as playing music of the tablet 300). At this time, the audio service 1 of the mobile phone 200 is preempted by the audio service 2 of the tablet 300. Among them, the mobile phone 200 and the tablet 300 can respectively establish a wireless communication channel with the Bluetooth headset 100 through a physical connection, and the physical connection can include an asynchronous link (asynchronous connection-oriented link, ACL) connection in the wireless connection.

As another example, FIG4 shows a schematic diagram of an application scenario of an audio service processing method according to some embodiments of the present application. As shown in FIG4, the application scenario includes a mobile phone 200, a tablet 300, a user, and a Bluetooth headset 100 worn by the user. Among them, as shown in FIG2, the mobile phone 200 uses the Bluetooth headset 100 to process audio service 1, for example, using the Bluetooth headset 100 to play music. Afterwards, as shown in FIG4, the tablet 300 may detect music service 2, for example, the tablet 300 may receive an incoming call and needs to answer the call using the Bluetooth headset 100. At this time, the service priority of audio service 2 may be greater than or equal to the service priority of audio service 1. For example, when audio service 2 is answering an incoming call and audio service 1 is playing music, the service priority of audio service 2 is higher than the service priority of audio service 1.

When the tablet 300 determines that the service priority of audio service 2 is greater than or equal to the service priority of audio service 1, the tablet 300 can request the Bluetooth headset 100 to suspend processing of audio service 1 (such as playing music from the mobile phone 200) and use the Bluetooth headset 100 to process audio service 2 (such as answering a call from the tablet 300). At this time, the audio service 1 of the mobile phone 200 is preempted by the audio service 2 of the tablet 300.

In this way, the tablet 300 can control the Bluetooth headset to process more important audio services according to the pre-set service priority, thereby improving the user experience.

Although the above solution takes the priority of audio services into consideration and improves the user experience, if a service conflict occurs in the Bluetooth headset, the Bluetooth headset will only process an audio service with a higher service priority, and suspend the processing of other audio services with lower service priorities. Other audio services with lower service priorities will be shelved and not processed, which will also affect the user experience.

In order to solve this technical problem, in the audio service processing method provided in the embodiment of the present application, after the electronic device 2 requests the Bluetooth headset to suspend processing of the audio service 1 and uses the Bluetooth headset to process the audio service 2, the method further includes: the electronic device 1 uses its own audio component to process the audio service 1. In this way, when the Bluetooth headset is connected to multiple electronic devices and multiple audio services are sent to the Bluetooth headset in parallel, the multiple audio services can be allocated to the corresponding audio playback devices, which solves the problem of selecting a suitable audio playback device under the concurrent transmission of multiple audio services and improves the user experience.

For example, for the application scenario in FIG. 4 , the tablet 300 requests the Bluetooth headset 100 to pause playing the music of the mobile phone 200, and uses the Bluetooth headset 100 to play the call of the tablet 300, and the Bluetooth headset 100 pauses playing the music of the mobile phone 200. After playing the call on the tablet 300, the mobile phone 200 plays the music using its own speaker, plugging in or unplugging headphones or a receiver.

In some embodiments, after the tablet 300 detects the audio service 2, it requests the Bluetooth headset 100 to suspend processing the audio service 1, and uses the Bluetooth headset 100 to process the audio service 2. Specifically, the following implementation scheme is included: FIG. 5 shows a schematic diagram of an application scenario of an audio service processing method according to some embodiments of the present application. As shown in FIG. 5, the tablet 300 detects the audio service 2. For example, the tablet 300 may receive an incoming call and needs to use the Bluetooth headset 100 to answer the call; or, the tablet 300 may need to use the Bluetooth headset 100 to play music. The tablet 300 sends a service suspension instruction to the mobile phone 200 through the Bluetooth headset 100. The mobile phone 200 can receive the service suspension instruction. After receiving the service suspension instruction, the mobile phone 200 can stop sending audio data of the audio service 1 to the Bluetooth headset 100, such as playing the audio data corresponding to the music of the mobile phone 200. In addition, the tablet 300 can send audio data of the audio service 2 to the Bluetooth headset 100. The Bluetooth headset 100 receives the audio data of the audio service 2 and processes the audio service 2, such as using the Bluetooth headset 100 to play the music of the tablet 300.

In this embodiment, the tablet 300 can request the Bluetooth headset 100 to suspend processing of the audio service 1 through a service suspension instruction, and use the Bluetooth headset 100 to process the audio service 2, so that the audio service 2 preempts the audio service 1.

It should be noted that, in this embodiment, the Bluetooth headset 100 can play the role of transferring data or signaling (such as the above-mentioned service suspension instruction) between the tablet 300 and the mobile phone 200. The Bluetooth headset 100 can transparently transmit the data or signaling received from the tablet 300 to the mobile phone 200, and can also transparently transmit the data or signaling received from the mobile phone 200 to the tablet 300.

In other embodiments, after receiving data or signaling from the tablet 300 or the mobile phone 200, the Bluetooth headset 100 will also respond to the data or signaling and perform some corresponding operations. For example, after receiving a service suspension instruction from the tablet 300, the Bluetooth headset 100 will not only transmit the service suspension instruction to the mobile phone 200, but also stop processing the audio service 1 of the mobile phone 200 in response to the service suspension instruction.

In some embodiments, after the tablet 300 detects the audio service 2, it requests the Bluetooth headset 100 to suspend processing the audio service 1, and uses the Bluetooth headset 100 to process the audio service 2, including the following specific implementation scheme: the mobile phone 200 indicates the service priority of the audio service 1 to the tablet 300 through the Bluetooth headset 100; after the tablet 300 detects the audio service 2, it compares the service priority of the audio service 2 with that of the audio service 1; if the service priority of the audio service 2 is greater than the service priority of the audio service 1, the tablet 300 requests the Bluetooth headset 100 to suspend processing the audio service 1, and uses the Bluetooth headset 100 to process the audio service 2.

In some embodiments, the service pause instruction is used to indicate the service priority of audio service 2; the mobile phone 200 receives the service pause instruction and stops sending audio data of audio service 1 to the Bluetooth headset 100, including the following specific implementation scheme: the mobile phone 200 receives the service pause instruction, if the service priority of audio service 2 indicated by the service pause instruction is greater than the service priority of audio service 1, stops sending audio data of audio service 1 to the Bluetooth headset 100.

In this solution, after receiving the service suspension instruction, the mobile phone 200 will reconfirm the service priorities of the audio service 2 and the audio service 1, so as to further ensure the accuracy of the execution of the service suspension instruction by the mobile phone 200.

815 : The audio service 302 sends the music data to the Bluetooth headset 100 via the Bluetooth service 301 .

816: The Bluetooth headset 100 plays music based on the music data.

In some embodiments, the tablet 300 requests the Bluetooth headset 100 to pause playing the music of the mobile phone 200, and uses the Bluetooth headset 100 to play the music of the tablet 300. The Bluetooth headset 100 pauses playing the music of the mobile phone 200. After playing the call of the tablet 300, the mobile phone 200 uses its own speaker, plugs in and out headphones or receivers, etc. to play music, and at the same time displays the current audio service processing device (audio input and output device) on the display interface of the mobile phone 200. For example, FIG9 shows a schematic diagram of a notification management interface according to some embodiments of the present application. As shown in FIG9, the display interface of the mobile phone 200 shows that the current audio service processing device (audio input and output device) is the local device.

FIG10 shows a schematic diagram of the structure of a Bluetooth headset 100 according to some embodiments of the present application. As shown in FIG10 , the Bluetooth headset 100 may include at least one processor 101, at least one memory 102, a wireless communication module 103, an audio module 104, a power module 105, and an input/output interface 106, etc. The processor may include one or more interfaces for connecting to other components of the Bluetooth headset 100. The Bluetooth headset 100 is stored in an earphone box. The various components of the Bluetooth headset 100 are specifically introduced below in conjunction with FIG10 .

The memory 102 can be used to store program codes, such as for physically connecting the Bluetooth headset 100 with multiple electronic devices, and for connecting with electronic devices in accordance with business regulations, processing audio services of electronic devices (such as music playback, answering/calling, etc.), and for charging the Bluetooth headset 100. The memory 102 may also be used to store other information, such as the priority of the electronic device.

The processor 101 can be used to execute the above application code and call related modules to implement the functions of the Bluetooth headset 100 in the embodiment of the present application. For example, the Bluetooth headset 100 can be connected physically to multiple electronic devices (such as electronic device 1 and electronic device 2), and can be connected to different electronic devices according to device priority. The physical connection is a connection based on a physical link, which may include an ACL connection or a low energy asynchronous connection link (low energy asynchronous connection link/logical transport, LE ACL) connection. Exemplarily, when the Bluetooth headset establishes a physical connection with the electronic device 1 and is processing the audio service 1 of the electronic device 1 (such as playing music), if the Bluetooth headset receives the connection request information of the electronic device 2, the Bluetooth headset can process the audio service 2 of the electronic device 2 (such as answering/making a call) based on the physical connection with the electronic device 2, so as to realize the service preemption function of the audio service 2 of the electronic device 2.

The processor 101 may include one or more processing units, and different processing units may be independent devices or integrated into one or more processors 101. The processor 101 may specifically be an integrated control chip, or may be composed of a circuit including various active and/or passive components, and the circuit is configured to perform the functions of the processor 101 described in the embodiments of the present application.

The wireless communication module 103 can be used to support data exchange between the Bluetooth headset 100 and other electronic devices or earphone boxes through wireless communication technology, such as BT, WLAN (such as Wi-Fi), Zigbee, FM, NFC, IR, or general 2.4G/5G wireless communication technology.

In some embodiments, the wireless communication module 103 may be a Bluetooth chip. The Bluetooth headset 100 may be paired with a Bluetooth chip of another electronic device through the Bluetooth chip and establish a wireless connection to achieve wireless communication and service processing between the Bluetooth headset 100 and the other electronic device through the wireless connection. Generally, the Bluetooth chip may support basic rate (BR)/enhanced data rate (EDR) Bluetooth and BLE, for example, it may receive/send paging information, receive/send BLE broadcast messages, etc.

In addition, the wireless communication module 103 may also include an antenna, and the wireless communication module 103 receives electromagnetic waves via the antenna, modulates the electromagnetic wave signal and performs filtering, and sends the processed signal to the processor 101. The wireless communication module 103 may also receive a signal to be sent from the processor 101, modulate the frequency of the signal, amplify the signal, and convert it into an electromagnetic wave for radiation through the antenna.

The audio module 104 can be used to manage audio data and implement the input and output audio streams of the Bluetooth headset 100. For example, the audio module 104 can obtain an audio stream from the wireless communication module 103, or transmit an audio stream to the wireless communication module 103, to implement functions such as making and receiving calls, playing music, starting/turning off the voice assistant of the electronic device connected to the headset, and receiving/sending the user's voice data through the Bluetooth headset. The audio module 104 may include a speaker (or earpiece, receiver) component for outputting an audio stream, a microphone (or microphone, microphone), a microphone receiving circuit matched with the microphone, etc. The speaker can be used to convert an audio electrical signal into a sound signal and play it. The microphone can be used to convert a sound signal into an audio electrical signal.

The power module 105 can be used to provide system power for the Bluetooth headset 100, power each module of the Bluetooth headset 100, and support the Bluetooth headset 100 to receive charging input. The power module 105 may include a power management unit (PMU) and a battery. The power management unit can receive external charging input; transform the electrical signal input from the charging circuit and provide it to the battery for charging; and can also transform the electrical signal provided by the battery and provide it to the battery for charging. Supplying other modules such as the audio module 104 and the wireless communication module 103; and preventing the battery from being overcharged, over-discharged, short-circuited or over-current, etc. In some embodiments, the power module 105 may also include a wireless charging coil for wirelessly charging the Bluetooth headset 100. In addition, the power management unit may also be used to monitor parameters such as battery capacity, battery cycle number, battery health status (leakage, impedance), etc.

The multiple input/output interfaces 106 can be used to provide a wired connection for charging or communication between the Bluetooth headset 100 and the headset box. In some embodiments, the input/output interface can be a USB interface. In other embodiments, the input/output interface 106 can be a headset electrical connector. When the Bluetooth headset 100 is placed in the headset box, the Bluetooth headset 100 can establish an electrical connection with the electrical connector in the headset box through the headset electrical connector, thereby charging the battery in the Bluetooth headset 100. In other embodiments, after the electrical connection is established, the Bluetooth headset 100 can also communicate data with the headset box, for example, it can receive a pairing instruction from the headset box.

In addition, the Bluetooth headset 100 may further include a sensor 107. For example, the sensor 107 may be a distance sensor or a proximity light sensor, which may be used to determine whether the Bluetooth headset 100 is worn by the user. Exemplarily, the Bluetooth headset 100 may use the distance sensor to detect whether there is an object near the Bluetooth headset 100, thereby determining whether the Bluetooth headset 100 is worn by the user. When it is determined that the Bluetooth headset 100 is worn, the Bluetooth headset 100 may turn on the speaker.

For another example, the sensor 107 may also include a bone conduction sensor, combined into a bone conduction headset. Using the bone conduction sensor, the Bluetooth headset 100 can obtain the vibration signal of the human vocal bone, parse the voice signal, implement the voice function, and thus receive the user's voice command. The Bluetooth headset 100 can also perform voice authentication based on the user's voice signal obtained by the bone conduction headset to authenticate the user's identity in business scenarios such as payment transactions.

For another example, the sensor 107 may also include: a touch sensor for detecting a user's touch operation; a fingerprint sensor for detecting a user's fingerprint and identifying the user's identity; an ambient light sensor that can adaptively adjust some parameters (such as volume) according to the perceived brightness of the ambient light; and other possible sensors.

In some embodiments, the touch sensor can detect the user's touch operations such as single click, double click, multiple clicks, long press, and heavy pressure, and can also perform user fingerprint recognition to authenticate the user's identity in business scenarios such as payment transactions.

It is understandable that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the Bluetooth headset 100. It may have more or fewer components than those shown in FIG. 10, may combine two or more components, or may have different component configurations. For example, the outer surface of the Bluetooth headset 100 may also include a button 108, an indicator light (which may indicate battery level, incoming/outgoing call, pairing mode, etc.), a display screen (which may prompt the user with relevant information), a dust screen (which may be used in conjunction with a handset), and other components. Among them, the button 108 may be a physical button or a touch button (used in conjunction with a touch sensor), etc., which is used to trigger operations such as power on, power off, pause, play, record, start pairing, and reset.

The various components shown in Figure 10 can be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing or application-specific integrated circuits. Exemplarily, when the Bluetooth headset is a TWS headset, the Bluetooth headset 100 may include an earphone body (also called the left earplug, or the first part) worn on the left ear and an earphone body (also called the right earplug, or the second part) worn on the right ear. The earphone body may include a housing and internal components. The internal components are arranged in a cavity formed by the housing. The internal components may include devices in modules such as the above-mentioned audio module, power module, and wireless communication module.

When the Bluetooth headset is a TWS headset, the user can use the TWS headset in binaural mode or monaural mode. In monaural mode, the user wears the left earbud or the right earbud to listen to music or answer/make phone calls and other audio services. In binaural mode, the user can wear two earbuds to enjoy music or perform other audio services. In binaural mode, the two earbuds are divided into main earbuds and auxiliary earbuds. Moreover, during the use of TWS headphones, the main and auxiliary roles of the two earbuds can also be switched based on different conditions. For example, the earbud with higher power can be switched to the main earbud, and the earbud with lower power can be switched to the auxiliary earbud.

In some embodiments, the Bluetooth headset is usually stored in an earphone box. The earphone box may have one or more magnets inside to attract the earphone body into the cavity in the earphone box. The earphone box may include a battery and multiple input/output interfaces. In some embodiments, the input/output interface may be a box electrical connector. When a pair of box electrical connectors in the earphone box are electrically connected to two earphone electrical connectors in the earphone body, the earphone box can charge the battery in the earphone body through its own battery.

In other embodiments, the headset box may be provided with at least one touch control, which can be used to trigger the Bluetooth headset to perform pairing reset or charge the Bluetooth headset. The headset box may also be provided with one or more power indicator lights to prompt the user the power level of the battery in the headset box and the power level of the battery in each headset body in the headset box.

In other embodiments, the earphone box may further include components such as a processor and a memory. The memory may be used to store application code, and the processor of the earphone box controls execution to implement various functions of the earphone box. For example, the processor of the earphone box executes the application code stored in the memory, and charges the Bluetooth headset after detecting that the Bluetooth headset is placed in the earphone box and the lid of the earphone box is closed.

In addition, the earphone box may be provided with a charging interface for charging the battery of the earphone box. The earphone box may also include a wireless charging coil for wirelessly charging the battery of the earphone box. It is understandable that the earphone box may also include other components, which will not be described one by one here.

It can be understood that the components shown in FIG. 10 do not constitute a specific limitation on the Bluetooth headset 100 , and the Bluetooth headset 100 may also include more or fewer components than shown in the figure, or combine certain components, or separate certain components, or arrange the components differently.

It is understandable that Bluetooth headsets can connect to multiple electronic devices, but they can only process the audio service of an electronic device with a higher service priority according to the service priority order set for the audio service, but cannot process the audio service of other electronic devices according to the user's wishes. The flexibility of audio service switching is poor and the user experience is poor.

For example, as shown in FIG2 , the application scenario includes a Bluetooth headset 100, a mobile phone 200, and a tablet 300. The Bluetooth headset 100 simultaneously establishes wireless communication connections with the mobile phone 200 and the tablet 300, thereby cooperating with the mobile phone 200 and the tablet 300 to process audio services for the user. Currently, after the mobile phone 200 initiates a request to play music to the Bluetooth headset 100, the Bluetooth headset 100 plays the music of the mobile phone 200.

As shown in FIG3 , if the tablet 300 detects an audio service of playing music and determines that the service priority of the tablet 300 playing music is greater than or equal to the service priority of the mobile phone 200 playing music, it requests the Bluetooth headset 100 to pause playing the music of the mobile phone 200 and play the music of the tablet 300, so that the Bluetooth headset 100 pauses playing the music of the mobile phone 200 and plays the music of the tablet 300. In this process, the Bluetooth headset 100 cannot switch to playing the music of the mobile phone 200 again according to the user's wishes, the flexibility of audio service switching is poor, and the user experience is poor.

In order to solve the above technical problems, the embodiment of the present application provides an audio service recovery processing method. In this method, both electronic device 1 and electronic device 2 establish a wireless communication channel with a Bluetooth headset. Then, when electronic device 1 uses the Bluetooth headset to process audio service 1, and electronic device 2 detects audio service 2, it can request the Bluetooth headset to The processing of audio service 1 is suspended, and the Bluetooth headset is used to process audio service 2. The audio service priority of audio service 2 is greater than or equal to the audio service priority of audio service 1. The electronic device 1 described in the embodiment of the present application is a first electronic device, the electronic device 2 is a second electronic device, the audio service 1 is a first audio service, and the audio service 2 is a second audio service.

Furthermore, after the Bluetooth headset suspends processing of the audio service 1, the electronic device 1 may display a first prompt message, wherein the first prompt message is used to request the user to determine whether the electronic device 1 resumes processing the audio service 1 using the Bluetooth headset. After the electronic device 1 responds to the user's confirmation operation on the first prompt message, the Bluetooth headset is requested to suspend processing of the audio service 2, and the Bluetooth headset is used to process the audio service 1, wherein the first operation is used to trigger the electronic device 1 to resume processing the audio service 1 using the Bluetooth headset. Then, the electronic device 1 resumes processing the audio service 1 using the Bluetooth headset.

The software system of the mobile phone 200 may adopt a layered architecture, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes the Android system of a layered architecture as an example to exemplify the software structure of the mobile phone 200.

FIG. 11 shows a software structure diagram of a mobile phone 200 according to some embodiments of the present application. The layered architecture divides the software into several layers, each with clear roles and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, namely, from top to bottom, the application layer, the application framework layer, the Android Runtime and the system library, and the kernel layer.

As shown in Figure 11, the application layer may include applications such as music, video, call, ringtone, alarm, Bluetooth, navigation, audio manager, gallery, recording, etc. Of course, the application layer may also include other applications, such as payment applications, shopping applications, banking applications, chat applications or financial management applications, etc., which are not limited in this application. Among them, the audio manager is used to sense the state of the Bluetooth headset processing audio services: idle, processing audio services. The audio manager is also used to sense the preemption event of the audio service and the state recovery event of the audio service. Among them, the preemption of the audio service refers to the process of suspending the processing of the audio service being processed and processing the audio service initiated by another electronic device when the Bluetooth headset processes the audio service, and then suspending the processing of the audio service being processed and processing the audio service initiated by another electronic device. The state recovery event of the audio service refers to the process of the Bluetooth headset suspending the processing of the audio service initiated by another electronic device after the preemption event of the audio service occurs, and processing the audio service that was previously suspended. The audio manager is also used to display a first prompt message, which is used to instruct the user to select the preemption processing of the audio service and the state recovery processing of the audio service. For example, the audio manager is used to display the aforementioned "one-key grab back" pop-up window.

The application framework layer provides an application programming interface (API) and a programming framework for the applications of the application layer. The application framework layer includes some predefined functions. For example, it may include a phone manager, a computing engine, a notification manager, a multimedia framework, a state perception module, a process manager, etc., and the embodiments of the present application do not impose any restrictions on this.

Among them, the process manager is used to create and terminate processes and threads.

The phone manager is used to provide the communication functions of the mobile phone 200. For example, the management of the call status (including connecting, hanging up, etc.) wait).

The notification manager enables applications to display notification information in the status bar. It can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify download completion, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as notifications of applications running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is displayed in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

The state perception module is mainly responsible for confirming the state of the mobile phone 200 itself and the state of the wireless device (e.g., Bluetooth headset 100) connected to the mobile phone 200 via Bluetooth. Among them, the state of the mobile phone 200 itself may include an activated state and an inactivated state, and the state of the device connected to the mobile phone via Bluetooth may include an idle state or a non-idle state. The state perception module can confirm the state of the mobile phone 200 itself by monitoring various application processes and threads. The state perception module can determine the state of the device connected to the mobile phone 200 via Bluetooth through the received broadcast information (e.g., BLE broadcast).

The multimedia framework can receive audio services sent by various applications in the application layer, identify the type of audio services, and perform service arbitration and preemption. In an embodiment of the present application, the multimedia framework is used to determine the type of audio service based on the audio stream type in the audio service request when receiving a request to process an audio service sent by an application, and then select an audio playback device based on the state of the Bluetooth headset processing the audio service. The multimedia framework is also used to send an audio service preemption notification to the Bluetooth module when receiving an audio service preemption notification sent by an audio manager.

The system library can include multiple functional modules, such as surface manager, media library, 3D graphics processing library (e.g., OpenGL ES), 2D graphics processing library (e.g., SGL), etc.

The surface manager is used to manage the display subsystem and provide the fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

OpenGL ES is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

SGL is a graphics engine for 2D graphics.

Android Runtime includes core libraries and virtual machines. Android Runtime is responsible for scheduling and management of the Android system. The core library consists of two parts: one is the function that the Java language needs to call, and the other is the Android core library. The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform object life cycle management, stack management, thread management, security and exception management, and garbage collection.

The kernel layer is the layer between hardware and software. The kernel layer contains at least display driver, camera driver, audio driver, sensor driver, and Bluetooth module.

In addition, there is a hardware layer between the system library and the kernel layer, which includes a display, camera, speaker (also called loudspeaker) and Bluetooth module. The Bluetooth module may include hardware units for Bluetooth connection and data interaction: wireless radio unit (Radio), baseband or link control unit (link controller), link management unit (link manager), etc. The wireless radio unit is used to realize the wireless radio unit (Radio) for sending/receiving data and voice; the link management unit is used to convert radio frequency signals into digital or voice signals to realize Baseband protocol and other underlying connection procedures; the link management unit is responsible for managing the communication between Bluetooth devices and implementing operations such as link establishment, verification, and link configuration.

The following embodiments introduce the application scenarios of the embodiments of the present application and the methods of the embodiments of the present application in conjunction with the accompanying drawings.

In the embodiment of the present application, as shown in FIG2, both the mobile phone 200 and the tablet 300 can establish a wireless communication channel (such as a physical connection) with the Bluetooth headset 100. The mobile phone 200 can use the Bluetooth headset 100 to process the audio service 1, such as using the Bluetooth headset 100 to play the music of the mobile phone 200. Afterwards, as shown in FIG3, the tablet 300 may detect the audio service 2. For example, the tablet 300 may receive an incoming call and need to answer the call using the Bluetooth headset 100; or, the tablet 300 may need to play music using the Bluetooth headset 100. At this time, the service priority of the audio service 2 may be greater than or equal to the service priority of the audio service 1. For example, when the audio service 2 is answering the incoming call and the audio service 1 is playing music, the service priority of the audio service 2 is higher than the service priority of the audio service 1. For another example, when the audio service 2 is playing music and the audio service 1 is playing music, the service priority of the audio service 2 is equal to the service priority of the audio service 1. The embodiment of the present application will later introduce the priority of each audio service, which will not be repeated here.

When the service priority of audio service 2 is greater than or equal to the service priority of audio service 1, tablet 300 can request Bluetooth headset 100 to suspend processing of audio service 1 (such as playing music from mobile phone 200) and use Bluetooth headset 100 to process audio service 2 (such as answering a call from tablet 300). At this time, audio service 1 of mobile phone 200 is preempted by audio service 2 of tablet 300.

In order to ensure that the audio service 1 of the mobile phone 200 can re-seize the right to use the Bluetooth headset 100 after being preempted by the audio service 2 of the tablet 300. The mobile phone 200 can provide the user with a "one-key retake" service. Specifically, the mobile phone 200 can display a first prompt message after the Bluetooth headset 100 suspends processing of the audio service 1. The first prompt message is used to request the user to determine whether the mobile phone 200 resumes using the Bluetooth headset 100 to process the audio service 1. In other words, the first prompt message is used to request the user to determine whether the audio service 1 is to re-seize the right to use the Bluetooth headset 100. For example, FIG. 12 shows a schematic diagram of an application scenario of an audio service recovery processing method according to some embodiments of the present application. As shown in FIG. 12, after the Bluetooth headset 100 pauses playing the music of the mobile phone 200 and plays the music of the tablet 300, the mobile phone 200 displays a "one-key retake" pop-up window. FIG. 13 shows a schematic diagram of an operation interface of a "one-key retake" window according to some embodiments of the present application. As shown in FIG. 13, the mobile phone 200 displays a "one-key retake" pop-up window 1. The "one-click reclaim" pop-up window 1 includes a prompt message: "Do you want to resume using the Bluetooth headset 100 to process the audio service 1?", as well as a confirmation option and a cancel option. When the mobile phone 200 detects that the user clicks the confirmation option in the "one-click reclaim" pop-up window 1, the audio service 1 of the mobile phone 200 can re-seize the right to use the Bluetooth headset 100. Figure 14 shows an application scenario schematic diagram of an audio service recovery processing method according to some embodiments of the present application. As shown in Figure 14, after the mobile phone 200 detects that the user clicks the confirmation option in the "one-click reclaim" pop-up window, the mobile phone 200 can request the Bluetooth headset 100 to pause playing the music of the tablet 300, and use the Bluetooth headset 100 to play the music of the mobile phone 200, so that the Bluetooth headset 100 resumes playing the music of the mobile phone 200. The first prompt message can be displayed on the desktop of the mobile phone 200, can also be displayed in the interface of the audio application, and can also be displayed in the drop-down notification management menu of the mobile phone 200.

In this solution, the priority of processing services is not determined simply according to the service priority order set for audio services. The audio service of an electronic device with a higher frequency. After pausing the music played by the mobile phone 200, the user can decide whether to continue the audio service. Afterwards, the user can choose whether to resume the preempted music played by the mobile phone 200 according to the user's wishes. In this way, the flexibility of audio service switching is improved, and the user experience is improved.

In the embodiment of the present application, different audio services may correspond to different priorities. Audio services with higher priorities are usually important and critical audio services, and audio services with higher priorities may be processed preferentially by Bluetooth headsets. Exemplarily, audio services may include multiple types, such as audio services may include call services, multimedia services, notification services, etc. Call services may include playing the voice data of the other end for the user in scenarios such as phone calls (including incoming and outgoing calls), video calls, audio calls, voice messages, games or voice assistants, or collecting the user's voice data and sending it to the other end, as well as playing incoming call ringtones, etc. Multimedia services may include playing music, videos, recordings, background music for games, text-to-speech sounds, etc. Notification services may include playing SMS prompts, push notification prompts, alarm ringtones, system sounds (such as sounds when adjusting the volume, shutter sounds when shooting, etc.). The priorities of notification services, multimedia services, and call services increase in sequence. In other embodiments, audio services may include more types, which are not specifically limited here. Among them, the priority of the audio service may be pre-set or actively set by the user, which is not specifically limited here. For example, the service priority of the call service is higher than the service priority of the multimedia service, and the service priority of the multimedia service is higher than the service priority of the notification service.

In some embodiments, after the tablet 300 detects the audio service 2, it requests the Bluetooth headset 100 to suspend processing the audio service 1, and uses the Bluetooth headset 100 to process the audio service 2. Specifically, the following implementation schemes are included: FIG. 15 shows a schematic diagram of an application scenario of an audio service recovery processing method according to some embodiments of the present application. As shown in FIG. 15, the tablet 300 detects the audio service 2. For example, the tablet 300 may receive an incoming call and needs to use the Bluetooth headset 100 to answer the call; or, the tablet 300 may need to use the Bluetooth headset 100 to play music. The tablet 300 sends a service suspension instruction to the mobile phone 200 through the Bluetooth headset 100. The mobile phone 200 can receive the service suspension instruction. After receiving the service suspension instruction, the mobile phone 200 can stop sending audio data of the audio service 1 to the Bluetooth headset 100, such as playing the audio data corresponding to the music of the mobile phone 200. In addition, the tablet 300 can send audio data of the audio service 2 to the Bluetooth headset 100. The Bluetooth headset 100 receives the audio data of the audio service 2 and processes the audio service 2, such as using the Bluetooth headset 100 to play the music of the tablet 300.

In some embodiments, after the tablet 300 detects the audio service 2, it requests the Bluetooth headset 100 to suspend processing the audio service 1, and uses the Bluetooth headset 100 to process the audio service 2, including the following specific implementation scheme: the mobile phone 200 indicates the service priority of the audio service 1 to the tablet 300 through the Bluetooth headset 100; the tablet 300 detects the audio service 2, and the Bluetooth headset 100 suspends processing the audio service 1. After processing audio service 2, the tablet 300 compares the service priorities of audio service 2 and audio service 1; if the service priority of audio service 2 is greater than the service priority of audio service 1, the tablet 300 requests the Bluetooth headset 100 to suspend processing audio service 1 and use the Bluetooth headset 100 to process audio service 2.

In some embodiments, the service suspension instruction is used to indicate the service priority of audio service 2; the mobile phone 200 receives the service suspension instruction and stops sending the audio data of audio service 1 to the Bluetooth headset 100, including the following specific implementation scheme: the mobile phone 200 receives the service suspension instruction, and if the service priority of audio service 2 indicated by the service suspension instruction is greater than the service priority of audio service 1, stops sending the audio data of audio service 1 to the Bluetooth headset 100. In this scheme, after receiving the service suspension instruction, the mobile phone 200 will reconfirm the service priorities of audio service 2 and audio service 1, further ensuring the accuracy of the mobile phone 200 executing the service suspension instruction.

It can be understood that when the audio services that require the right to use the Bluetooth headset 100 at the same time are at the same service priority, the tablet 300 that initiates the audio service later can display a prompt message for requesting the user to determine whether the tablet 300 preempts the Bluetooth headset 100 to process the audio service 2. In this way, the user's willingness can determine whether to process the audio service 2 initiated later first, thereby improving the user experience. Specifically, in some embodiments, if the service priority of the audio service 2 is equal to the service priority of the audio service 1, the tablet 300 displays a second prompt message; wherein the second prompt message is used to request the user to determine whether the tablet 300 preempts the Bluetooth headset 100 to process the audio service 2; the tablet 300 responds to the user's third operation on the second prompt message, requests the Bluetooth headset 100 to suspend the processing of the audio service 1, and uses the Bluetooth headset 100 to process the audio service 2; wherein the third operation is used to trigger the tablet 300 to preempt the Bluetooth headset 100 to process the audio service 2. The second prompt message can be displayed on the desktop of the tablet 300, can also be displayed on the interface of the audio application of the tablet 300, and can also be displayed in the drop-down notification management menu of the tablet 300. The operation interface of the tablet 300 may include the second prompt information and a corresponding confirmation option button at the same time, and the third operation may be a selection operation of the user on the confirmation option button corresponding to the second prompt information, for example, the user clicks the confirmation option button.

It can be understood that in order to improve the efficiency of mobile phone 200 in resuming the originally suspended audio service, the display time of the first prompt information needs to be controlled within a certain time. If the user's first operation on the first prompt information is detected within the control time, mobile phone 200 resumes the originally suspended audio service.

Specifically, in some embodiments, if the mobile phone 200 receives a first operation of the user on the first prompt information within a first preset time, the mobile phone 200, in response to the first operation, requests the Bluetooth headset 100 to suspend processing of audio service 2, and uses the Bluetooth headset 100 to process audio service 1. The first preset time can be any time from 10 seconds to 1 minute.

In some other embodiments, even if the mobile phone 200 does not detect that the user has timely selected to resume the originally suspended audio service, the mobile phone 200 can automatically resume using the Bluetooth headset 100 to process the audio service 1 after the Bluetooth headset 100 has processed the audio service 2. Specifically, if the mobile phone 200 does not receive the user's operation on the first prompt information within the first preset time, the mobile phone 200 can automatically resume using the Bluetooth headset 100 to process the audio service 1 after the Bluetooth headset 100 has processed the audio service 2. In this way, after the Bluetooth headset 100 has processed the audio service 2, the mobile phone 200 can automatically resume using the Bluetooth headset 100 to process the audio service 1 without the user's operation, thereby improving the user experience.

In some other embodiments, even if the mobile phone 200 detects that the user promptly selects not to resume the originally paused audio service, the mobile phone 200 can automatically resume processing the audio service 1 using the Bluetooth headset 100 after the Bluetooth headset 100 completes processing the audio service 2.

Specifically, if the mobile phone 200 receives the second operation of the user on the first prompt information within the first preset time, the second operation is used to trigger the mobile phone 200 not to resume using the Bluetooth headset 100 to process the audio service 1, and the mobile phone 200 automatically resumes using the Bluetooth headset 100 to process the audio service 1 after the Bluetooth headset 100 completes the processing of the audio service 2. Among them, the first prompt information can be displayed on the desktop of the mobile phone 200, or can be displayed on the interface of the audio application, or can be displayed in the drop-down notification management menu of the mobile phone 200. The operation interface of the mobile phone 200 can include the first prompt information and the corresponding cancel option button at the same time, and the second operation can be the user's selection operation of the cancel option button corresponding to the first prompt information, for example, the user clicks the cancel option button. In this way, after the Bluetooth headset 100 completes the processing of the audio service 2, the mobile phone 200 can automatically resume using the Bluetooth headset 100 to process the audio service 1 without the need for user operation, thereby improving the user experience.

In some other embodiments, even if the mobile phone 200 detects an instruction not to resume the originally paused audio service, if it detects that the tablet 300 suspends processing of the audio service 2 within the first preset time period, the idle Bluetooth headset 100 can be fully utilized to resume processing of the audio service 1, thereby improving the user experience.

Specifically, if the mobile phone 200 does not receive the user's operation on the first prompt information within the first preset time period, or the mobile phone 200 receives the user's second operation on the first prompt information within the first preset time period, the mobile phone 200 uses the Bluetooth headset to process the first audio service after the Bluetooth headset suspends processing the second audio service; wherein the second operation is used to trigger the mobile phone 200 not to resume using the Bluetooth headset to process the first audio service.

In some other embodiments, regardless of whether the mobile phone 200 detects that the user has selected to resume the originally paused audio service, the mobile phone 200 can automatically resume using the Bluetooth headset 100 to process audio service 1 after the Bluetooth headset 100 has completed processing audio service 2, or when the processing of audio service 2 is paused, thereby improving the user experience.

Specifically, the mobile phone 200 responds to the user's second operation on the first prompt information. If the tablet 300 uses the Bluetooth headset 100 to process the audio service 2 within the second preset time, the mobile phone 200 uses the Bluetooth headset 100 to process the audio service 1 after the Bluetooth headset 100 processes the audio service 2; or, the mobile phone 200 responds to the user's second operation on the first prompt information. If the tablet 300 pauses using the Bluetooth headset 100 to process the audio service 2 within the second preset time, the mobile phone 200 uses the Bluetooth headset 100 to process the audio service 1 after the Bluetooth headset 100 pauses processing the audio service 2; wherein the second operation is used to trigger the mobile phone 200 not to resume using the Bluetooth headset 100 to process the audio service 1. The second preset time can be any time between 3 minutes and 4 minutes. For example, the Bluetooth headset 100 pauses playing the media of the mobile phone 200 and plays the call of the tablet 300. If the call on the tablet 300 is hung up, if the media of the mobile phone 200 is still in a waiting state, and the duration from when the Bluetooth headset 100 paused playing the media of the mobile phone 200 to the current time is less than 3 minutes, the Bluetooth headset 100 resumes playing the media of the mobile phone 200.

In some embodiments, after the Bluetooth headset 100 suspends processing of audio service 1, the mobile phone 200 can also automatically process the pending audio service 1 to improve the completion of the audio service. After the tablet 300 detects the audio service 2, it requests the Bluetooth headset 100 to suspend processing of the audio service 1, and after using the Bluetooth headset 100 to process the audio service 2, the method also includes the following steps: the mobile phone 200 can mute or suspend the audio service 1, or use the audio component of the mobile phone 200 to process the audio service 1. The audio component can be a speaker, a plug-in headset, or a receiver. Specifically, if the audio service 1 is audio such as a call, Bluetooth recording, notification, or system, it can be directly switched to the audio component of the mobile phone 200 to continue the audio service. If the audio service 1 is a media type service, it can be paused (such as music, video), or muted (such as a game).

FIG20 shows a flowchart of an audio service recovery processing method according to some embodiments of the present application, corresponding to the application scenarios corresponding to FIG2, FIG3, FIG12 and FIG14. As shown in FIG20, the process includes the following: step:

131: The Bluetooth headset 100 establishes wireless communication channels with the mobile phone 200 and the tablet 300 respectively.

132: The Bluetooth headset 100 plays music from the mobile phone 200.

133: The tablet 300 detects that music is being played.

In some embodiments, the tablet 300 can detect a music service initiated by the user in response to the user's operation of playing selected music.

134: The Bluetooth headset 100 determines that the audio service priority of playing the music of the tablet 300 is greater than the audio service priority of playing the music of the mobile phone 200, and requests to pause playing the music of the mobile phone 200 and play the music of the tablet 300.

In the embodiment of the present application, different audio services of the electronic device may correspond to different priorities. Audio services with higher priorities are usually important and critical audio services, and audio services with higher priorities may be processed preferentially by Bluetooth headsets. Exemplarily, audio services may include multiple types, for example, audio services may include call services, multimedia services, notification services, etc. Call services may include playing the voice data of the other end for the user in scenarios such as phone calls (including incoming and outgoing calls), video calls, audio calls, voice messages, games or voice assistants, or collecting the user's voice data and sending it to the other end, as well as playing incoming call ringtones, etc. Multimedia services may include playing music, videos, recordings, background music of games, text-to-speech sounds, etc. Notification services may include playing SMS prompts, push notification prompts, alarm ringtones, system sounds (such as sounds when adjusting the volume, shutter sounds when shooting, etc.). The priorities of notification services, multimedia services, and call services increase in sequence. In other embodiments, audio services may include more types, which are not specifically limited here. Among them, the priority of the audio service may be pre-set or actively set by the user, which is not specifically limited here. For example, the service priority of the call service is higher than the service priority of the multimedia service, and the service priority of the multimedia service is higher than the service priority of the notification service.

135: The Bluetooth headset 100 pauses playing the music on the mobile phone 200 and plays the music on the tablet 300.

136: The Bluetooth headset 100 sends a pause notification message to the mobile phone 200.

137: The mobile phone 200 displays a first prompt message, where the first prompt message is used to request the user whether to resume using the Bluetooth headset 100 to play the music audio service of the mobile phone 200.

138: The mobile phone 200 responds to the user's confirmation operation on the first prompt information.

The first prompt information is used to request the user to determine whether the mobile phone 200 resumes playing music using the Bluetooth headset 100.

The first prompt information may be a pop-up window of "One-click Retrieval". The confirmation operation may be that the user clicks on the confirmation option in the pop-up window of "One-click Retrieval".

139: The mobile phone 200 requests the Bluetooth headset 100 to pause playing the music on the tablet 300.

In some embodiments, after the mobile phone 200 requests the Bluetooth headset 100 to pause playing the music of the tablet 300, the Bluetooth headset 100 pauses playing the music of the tablet 300. After playing the music of the mobile phone 200, the tablet 300 can play the music using its own speakers, plugging and unplugging headphones or receivers, etc. Specifically, if the audio service 1 is audio such as calls, Bluetooth recordings, notifications, or systems, the audio service can be directly switched to the audio component of the tablet 300 to continue. If the audio service 1 is a media type service, it can be paused (such as music, video), or muted (such as games).

In some embodiments, when the tablet 300 is using the Bluetooth headset 100 to play music and is preempted by the music playing service initiated by the mobile phone 200, the Bluetooth headset 100 will record the music playing status of the mobile phone 200 in order to resume the tablet 300 using the Bluetooth headset 100 to play music when the Bluetooth headset 100 is released. For example, as shown in FIG. 19: When the board 300 detects the user's operation of pausing music playing, it pauses the use of the Bluetooth headset 100 to play music. The Bluetooth headset 100 is idle, and notifies the mobile phone 200 of a notification of resuming music playing (referred to as the resume notification in the figure) and the headset status. The Bluetooth headset 100 forwards the notification of resuming music playing and the headset status to the audio manager 202 and the multimedia framework 203 respectively. The audio manager 202 calls the interface of the multimedia framework 203, and then the multimedia framework 203 notifies the audio application 201 to play music.

1310: The Bluetooth headset 100 plays music from the mobile phone 200.
