Based on the aforementioned hardware structure of the electronic device 100, in the embodiments of the present application, the software system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiments of the present application take an Android system with a layered architecture as an example to exemplarily describe the software structure of the electronic device 100 . The Android system is only a system example of the electronic device 100 in the embodiment of the present application, and the present application can also be applied to other types of operating systems, such as IOS, windows, Hongmeng, etc., which is not limited in the present application. The following only takes the Android system as an example of the operating system of the electronic device 100 .

FIG. 4 is a block diagram of the software structure of the electronic device 100 according to the embodiment of the present application.

The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into three layers, which are an application layer, a middleware layer and an operating system layer from top to bottom.

The application layer can include a series of application packages.

As shown in Figure 4, the application package can include applications such as SMS, call, map, navigation, music, video, gallery and so on.

Middleware is a type of computer software that connects software components and applications, and includes a set of services. The main function is to provide a running and development environment for the application software (application package) in the upper layer, helping users to develop and integrate complex application software flexibly and efficiently; programming interface, API) and programming frameworks. Middleware is an independent system software or service program. Distributed application software uses this software to share resources among different technologies. Middleware is located on the client/server operating system to manage computer resources and network communication.

In the embodiment of the present application, the middleware provides a Bluetooth audio output service module, and the Bluetooth audio output service module includes a device information management module, an application information management module, and a decision management module. in,

The device information management module is used for discovering and recording devices and device information that have a Bluetooth connection relationship with the electronic device 100 and support audio output. Wherein, having a Bluetooth connection relationship means that a Bluetooth connection is in progress with the electronic device 100, or a Bluetooth connection has been established before. For example, in the system 10, the electronic device 100 establishes a Bluetooth connection with one or more Bluetooth devices 200, and the device information management module of the electronic device 100 can acquire the device information of one or more Bluetooth devices 200 that support audio output, and use the above devices to information is stored. The device information includes device identification (such as device name and/or device MAC address), device attributes (such as device audio capability, device interaction capability, etc.), device type (such as wearable device, vehicle-mounted device, home device, Bluetooth headset, etc.), the current status of the device (for example, the device is turned on or off, the screen is off or on, whether the device is worn on the user, etc.), the connection time of the device, and the priority information of the device, etc.

Exemplarily, as shown in Table 1,

Table 1

In some embodiments, the device information management module obtains the device information of the device that has a Bluetooth connection with the electronic device 100 and supports audio output from the operating system layer, and then uses the device identifier of the device (for example, the name of the device and/or the device ID of the device). MAC address) obtains the APP associated with the device from the application layer, and based on the APP associated with the device, the device information management module determines the device type of the device.

In Table 1, when the APP associated with the device is Sports Health, it can be judged that the device type corresponding to the device is a wearable device; when the APP associated with the device is Smart Life, it can be judged that the device type corresponding to the device is home equipment; when The device is not associated with other APPs, and the device type of the device can be determined through the device identification (eg, device name) or device attribute information. The device information in the device information management module may be updated periodically.

The application information management module is used to record application software installed on the electronic device 100 and software information corresponding to the application software. When new application software is installed in the electronic device 100 or the application software is uninstalled, the software information in the application information management module is updated. The software information includes an application name (or an application ID), an associated APP, whether it is necessary to call an audio device, and the like.

Specifically, when an APP is installed for the first time, it can be detected whether the APP needs to call the audio device by reading the content of the MANIFEST.XML file of the APP. If the file declares that audio permission is required, it is determined that the APP needs to call Audio device; it is also possible to determine whether the APP needs to call the audio device through the audio field of the APP. When a valid value is written in the audio field, it is determined that the APP needs to call the audio device.

The decision management module is used to combine the device information in the device information management module and the application software information in the application information management module to determine the device that outputs the audio of the application software according to a preset strategy.

The decision management module stores the corresponding relationship between the application software, the push scene, and the push device type. When the decision management module detects that the application software needs to call the audio device, it determines the current scene. Wherein, in different scenarios, the same application software can correspond to different audio output devices; in the same scenario, different application software can also correspond to different audio output devices. The decision management module can determine the audio output device among the currently connected devices in combination with the application software that needs to output audio and the current scene.

In the embodiment of the present application, exemplary, the push scene may include the following four categories: a driving scene, a sleeping scene, an indoor scene, and an outdoor scene. As shown in table 2,

Table 2

In Table 2, taking music software (eg, Huawei Music) as an example, the correspondence between application software, push scenarios, and push device types is exemplarily shown. For Huawei Music, in the driving scenario, the corresponding push device types can be in-vehicle devices and wearable devices. When the electronic device is connected to the in-vehicle device and the wearable device at the same time, the final push device is determined by priority as the in-vehicle device (in-vehicle device). The device has a higher priority); in the sleeping scenario, the corresponding push device type can be a Bluetooth headset; in the indoor scenario, the corresponding push device type can be a home device and a wearable device. When the electronic device is connected to the home device and wearable device at the same time When the device is selected, the final push device is determined by priority as a home device (home device has a higher priority).

In some embodiments, when the optional push device types include two or more types, the final push device may also be determined according to the number of pushes. Optionally, the device that has been pushed more times is the final pushed device.

Among them, the push method includes direct playback and voice confirmation. For example, the push method of home equipment is voice confirmation, that is, before the home equipment outputs the audio data of Huawei Music, it will output voice to the user to confirm whether to confirm the playback. After the command, output the audio data of Huawei Music.

The correspondence between the application software, the push scenario, and the push device type may be configured by the user, or may be configured by default in the electronic device 100 .

Optionally, in some embodiments, the decision management module further stores the corresponding relationship between environmental information, user status information, and output volume. The decision management module can determine the output volume of the audio data through environmental information and user status information. The environmental information includes information such as noise, weather, and temperature, and the user state includes information such as stress state and emotional state. Exemplarily, as shown in Table 3,

table 3

Current environment (e.g. noise, weather, temperature)	User stress state	Recommended output volume
Quiet, heavy rain, 25 degrees Celsius	normal	too small
Quiet, heavy rain, 25 degrees Celsius	Relax	too small
Normal, sunny, 25 degrees Celsius	Relax	normal
Noisy, sunny, 25 degrees Celsius	normal	too large

In Table 3, the corresponding relationship between the environmental information, the user state information, and the output volume is exemplarily shown. If the current ambient noise is quiet and the user's stress state is normal, the output volume is low (for example, 10-40 decibels); if the current ambient noise is quiet and the user's stress state is relaxed, the output volume is low (for example, 10-40 decibels). 30 decibels); the current ambient noise is normal, the user's stress state is relaxed, and the output volume is normal (for example, 40-60 decibels); and so on.

Optionally, in some embodiments, the decision management module further stores the corresponding relationship between the scene information and the output volume range. For example, in the driving scene, the interior of the car is a closed space, and the maximum output volume does not exceed 80 decibels; for example, in the sleeping scene, the maximum output volume does not exceed 50 decibels; for example, in the outdoor scene, the output volume is not limited. ;etc.

Optionally, in some embodiments of the present application, the decision management module may dynamically change the volume of the output sound according to the loudness of the ambient noise.

Optionally, in some embodiments, the decision management module can also determine the audio playback duration according to the user's navigation/track information. For example, the decision management module obtains the start time and expected end time of the navigation/track information, and determines the time or duration of the output audio.

The operating system layer provides a hardware management function, and is used to manage and allocate various resources (CPU, memory, input and output devices, etc.) of the electronic device 100 used by the application program. For example, when an application needs to be run, the operating system calls it into memory, and allocates memory space for the application to run and store data. For another example, when an application needs to output audio data, the operating system calls the audio output device to provide the application with a control service for the audio output device, and the like.

After the electronic device 100 and the Bluetooth device 1 establish a Bluetooth connection, the electronic device 100 obtains the device information of the Bluetooth device 1. The device information includes device identification (such as the name of the device and/or the MAC address of the device), device attributes (such as the audio capability of the device) , the interaction capability of the device, etc.), the type of the device (such as wearable devices, car devices, home devices, Bluetooth headsets, etc.), the current state of the device (such as the device is turned on or off, the screen is off or on, whether the device is worn on the user, etc. ), the connection time of the device, etc.

The electronic device 100 includes a device information management module, and the device information management module stores devices and device information that have a Bluetooth connection relationship with the electronic device 100 and support audio output. When the electronic device 100 establishes a Bluetooth connection with the Bluetooth device 1, the electronic device 100 acquires the device information of the Bluetooth device 1, and updates the information in the device information management module.

The above is a related description of the electronic device 100 acquiring the device information of the Bluetooth device 1 . It can be understood that the same is true for the electronic device 100 acquiring the device information of the Bluetooth device 2 .

Step S103: The electronic device 100 detects that the first application needs to output audio data.

The first application may be a third-party application, such as an instant messaging APP, an online shopping APP, a music APP, a game APP, etc.; it may also be a system application, such as an incoming call, a short message, an alarm clock, and the like. During the running process of the first application, the audio device may need to be called. For example: during the running of the instant messaging APP, the speaker playback device may be called to play the received voice messages; during the running of the music APP, the speaker playback device may be called to play the audio file; when there is an incoming call, it may be called Invoke the speaker playback device to play the ringtone for incoming calls; and so on.

Optionally, in some embodiments, during the running process of the first application, when the electronic device 100 detects that the first application starts an audio policy service (Audio Policy Service), the electronic device 100 may determine that the first application needs to output audio data. In this embodiment of the present application, the electronic device 100 detects that the first application needs to output audio data, which may be referred to as the electronic device 100 detecting the first play instruction of the first application. For example, the first play instruction of the first application may start an audio policy service for the first application.

Step S104: The electronic device 100 detects that the current scene information is the first scene.

The electronic device 100 determines the current scene information, that is, the scene in which the electronic device 100 detects that the electronic device 100 is currently located is the first scene. The scene information indicates the scene where the user using the electronic device 100 is currently located, for example, it may be in a car, at home, in a library, outdoors, and so on. Further, the scene information may also indicate the current scene and state of the user using the electronic device 100, such as driving, sleeping at home, reading in the library, exercising in the gym, and the like.

The following introduces several ways to determine the current scene information.

In a first manner, the electronic device 100 determines the scene information through device information connected by Bluetooth and the like.

For example, when the name of the Bluetooth device 1 connected to the electronic device 100 has the "Car" keyword, the electronic device 100 determines that the current scene is driving; or the device type of the Bluetooth device 1 connected to the electronic device 100 includes a vehicle-mounted device, then The electronic device 100 determines that the current scene is driving. When the device information of the Bluetooth device 1 connected to the electronic device 100 includes a home device, the electronic device 100 determines that the current scene is indoor or home.

In a second manner, the electronic device 100 determines the scene information through the state information of the electronic device 100 .

For example, the electronic device detects that the Smart Life App is activated, and the desk lamp is activated, and the current Bluetooth-connected devices include home devices, and the current scene is reading at home. For example, the electronic device detects that it is currently moving rapidly, and the current Bluetooth-connected device includes a vehicle-mounted device, and the current scene is driving.

In a third method, the scene information is determined by using the image collected by the camera.

When the electronic device 100 turns on the camera, the display interface of the electronic device 100 may not display the image captured by the camera. The electronic device 100 performs image recognition on the image captured by the camera to determine the current scene.

In a fourth manner, the location information of the electronic device 100 is acquired through GPS information, so as to determine the scene information.

For example, when the electronic device 100 determines that the current location is a library through GPS positioning, and detects that the ambient noise is lower than the threshold, the electronic device 100 determines that the current scene is in the library.

In a fifth manner, the electronic device 100 determines scene information in combination with sensor information/motion information detected by the wearable device.

The electronic device 100 detects that a connection is established with the wearable device, and the electronic device 100 obtains current motion information from the wearable device, thereby judging the scene information. For example, sports watches basically include running, cycling, walking, swimming and other sports modes, covering everything from daily sports to triathlons, which can meet the needs of sports enthusiasts at all levels. Wherein, the exercise mode may also include modes such as sleep and sitting.

For example, if the current exercise mode is elliptical machine, indoor running, indoor cycling, rowing machine, etc., and the current location is in the gym, the current scene is gym exercise; if the current exercise mode is outdoor running, outdoor walking, outdoor cycling, swimming, Mountaineering, cross-country, triathlon, etc., the current scene is outdoor sports; when the wearable device detects that the user is in sleep mode, the current scene is sleep.

Specifically, the electronic device 100 sends a request message to the wearable device, and in response to the request message, the wearable device sends the current exercise information to the electronic device. Optionally, the wearable device periodically provides the user's movement information to the electronic device.

Wherein, the above five ways are only exemplary ways, and the electronic device 100 can choose any one of the five ways listed, or the electronic device 100 can also freely combine at least one of the five ways listed above. Two, comprehensively judge the scene information to improve the accuracy of the scene information. Optionally, it is not limited to the above five methods, and the present application may also use other methods to obtain scene information, which is not limited in this application.

Step S105 : According to the first scenario, the electronic device 100 determines, among the connected Bluetooth devices, that the audio output device that supports outputting the audio data of the first application is the Bluetooth device 1 .

The electronic device stores the correspondence between application software, scene information and device types. After the electronic device determines that the current scene information is the first scene, it determines the audio output of the audio data of the first application in the connected Bluetooth device. The output device is Bluetooth device 1. The first application, the first scenario and the first device type correspond, and the device type of the Bluetooth device 1 is the first device type.

For example, the first application is Huawei Music, and the Bluetooth device 1 is an in-vehicle device. As shown in Table 2 above, in the "driving" scenario, the device types that support the audio output of Huawei Music are vehicle-mounted devices and wearable devices; if the current scenario is driving, the audio output device is Bluetooth device 1. For another example, the first application is Huawei Music, and the Bluetooth device 1 is a Bluetooth headset. In the "sleep" scenario, the device type that supports the audio output of Huawei Music is a Bluetooth headset; if the current scenario is sleeping, the audio output device is Bluetooth device 1.

The electronic device 100 determines an audio output device that supports audio output of the first application among the connected Bluetooth devices. That is to say, the audio output device is a device that has established a Bluetooth connection with the electronic device 100 and is a device that supports audio output of the first application.

In some embodiments, if in the same scenario, an application supports two or more device types of Bluetooth devices to output audio data, and the two or more device types of Bluetooth devices are established with the electronic device 100 For connection, the electronic device 100 can determine the only audio output device that outputs audio data through the priority information. For example, as shown in Table 2 above, in the "driving" scenario, the types of devices that support the audio output of Huawei Music are in-vehicle devices and wearable devices. The priority of in-vehicle devices is higher than that of wearable devices. When the in-vehicle device and the wearable device are connected to the electronic device 100 at the same time, the electronic device 100 selects the in-vehicle device to output the audio data of Huawei Music in the driving scenario. In this embodiment, the in-vehicle device is the first Bluetooth device, the device type of the in-vehicle device may be referred to as the first device type, the wearable device is the fourth Bluetooth device, and the device type of the wearable device may be referred to as the fourth device type.

Optionally, the only audio output device that outputs audio data may be determined according to the physical distance from the electronic device 100 . The electronic device 100 preferentially selects a device with a closer physical distance to the electronic device 100 as the audio output device; optionally, the only audio output device that outputs audio data can be determined according to the number of historical pushes, and the electronic device 100 preferentially selects the number of historical pushes More devices are used as audio output devices; optionally, the electronic device 100 can arbitrarily select one device as the audio output device.

Optionally, if there is no device type that supports outputting the audio data of the first application in the connected Bluetooth device, the electronic device 100 directly outputs the audio data of the application.

Step S106: Send the first instruction and the audio data of the first application.

When the electronic device 100 determines that the audio output device is the Bluetooth device 1, the electronic device 100 sends a first instruction and audio data of the first application to the Bluetooth device 1, where the first instruction is used to instruct the Bluetooth device 1 to output the audio data.

Step S107: The Bluetooth device 1 plays the audio data of the first application.

Based on the first instruction, the Bluetooth device 1 plays the audio data of the first application.

In some embodiments, after the electronic device 100 determines that the audio output device is the Bluetooth device 1, the electronic device 100 records that the number of historical pushes of the first application by the Bluetooth device 1 in the first scenario is increased by one.

Step S108: The electronic device 100 detects that the current scene information is the second scene.

In some embodiments, the electronic device 100 periodically detects the current scene information. The electronic device 100 detects that the current scene information is the second scene at the next moment in step S104.

The manner of detecting the current scene information by the electronic device 100 may refer to the relevant description of the manner of detecting the current scene information in the foregoing step S104 , which will not be repeated here.

Step S109 : According to the second scenario, the electronic device 100 determines, among the connected Bluetooth devices, that the audio output device that supports outputting the audio data of the first application is the Bluetooth device 2 .

The electronic device 100 stores the correspondence between application software, scene information and device types. After the electronic device 100 determines that the current scene information is the second scene, it determines that the audio output device that outputs the audio data of the first application is a Bluetooth device. 2. The first application, the second scenario and the second device type correspond, and the device type of the Bluetooth device 2 is the second device type.

Step S110: Send the second instruction and the audio data of the second application.

When the electronic device 100 determines that the audio output device is the Bluetooth device 2, the electronic device sends a second command and the audio data of the first application to the Bluetooth device 2, where the second command is used to instruct the Bluetooth device 2 to output the audio data.

Step S111: The Bluetooth device 2 plays the audio data of the first application.

Based on the second instruction, the Bluetooth device 2 plays the audio data of the first application.

In some embodiments, after the electronic device 100 determines that the audio output device is the Bluetooth device 2, the electronic device 100 records that the number of historical pushes of the first application by the Bluetooth device 2 in the second scenario is increased by one.

In the audio push method provided by the above embodiment, the electronic device establishes a connection with the Bluetooth device 1 and the Bluetooth device 2 . When the application software is running, the electronic device 100 continuously detects whether the application software needs to call the audio device. When the electronic device 100 detects the audio data of the first application, the electronic device 100 determines that the current scene information is the first scene. The corresponding relationship between application software, scene information and device type, it is determined that in the first scene, the Bluetooth device 1 outputs the audio data of the first application; when the electronic device 100 detects that the current scene information becomes the second scene, the electronic device 100 according to The stored correspondence between the application software, the scene information and the device type determines that in the second scene, the Bluetooth device 2 outputs the audio data of the first application. In this embodiment of the present application, in different scenarios, the audio data of the same application can be output by calling different devices. For example, when the user is at home, the user's smartphone establishes a Bluetooth connection with the Bluetooth headset, and when the user uses the music software (the first application) to play music, the smartphone detects that the current scene is home (the first scene), According to the corresponding relationship, the Bluetooth headset plays music; when the user comes out of the home wearing the Bluetooth headset and enters the car, the user's smartphone establishes a connection with the in-vehicle device, and the smartphone detects that the current scene is in the car (the second scene ), the smartphone calls the car device to play music, and the Bluetooth headset no longer plays music. There is no need for manual adjustment by the user, which improves the user experience.

Optionally, in some embodiments, at time T1, when the electronic device 100 detects the audio data of the first application, the electronic device 100 determines that the current scene information is the first scene, and the electronic device 100 determines the current scene information as the first scene according to the stored application software and scene information. The corresponding relationship with the device type, it is determined that in the first scenario, the first Bluetooth device outputs the audio data of the first application; at time T2, when the electronic device 100 detects the audio data of the second application, the electronic device 100 according to the stored application The correspondence between the software, the scene information and the device type determines that in the first scene, the third Bluetooth device outputs the audio data of the second application. In this embodiment of the present application, in the same scenario, audio data of different applications can be output by calling different devices. For example, when the user is sitting in the car, the first Bluetooth device is the in-vehicle device, the third Bluetooth device is the Bluetooth headset, and the user's smartphone establishes a Bluetooth connection with the in-vehicle device and the Bluetooth headset; when the user uses the music software (No. 1 application) when playing music, the smartphone detects that the current scene is in the car (the first scene), according to the corresponding relationship, the smartphone calls the vehicle device to play music, and when there is an incoming call (the second application), the Bluetooth headset gives priority to the incoming call The in-vehicle device will not output the ringtone to avoid the situation where everyone in the car hears the ringtone and improve the user experience.

In combination with the foregoing embodiments, optionally, in some embodiments, the electronic device 100 may further store the corresponding relationship between environmental information, user status information, and output volume. The foregoing Table 3 exemplarily shows the correspondence between the environment information, the user state information, and the output volume.

Then, step S104 (step S109 ) further includes determining the current environment information or user status information.

The electronic device 100 can collect ambient sound by invoking the microphone recording device, and detect the decibel size of the collected ambient sound, and the size of the noise is the decibel size of the ambient sound. Information such as weather and temperature may be acquired through a network, or acquired through an environmental sensor in the electronic device 100 .

The user state information includes information such as the user's stress index and mood index. If the Bluetooth device connected to the electronic device 100 includes a wearable device, the electronic device 100 requests the wearable device to acquire user status information. The wearable device can obtain the user's stress index, emotional index, etc. through biosensors (eg, electrodermal sensors, body temperature sensors, etc.). The wearable device sends the user state information to the electronic device 100 based on the request message obtained from the electronic device 100; or, the wearable device continuously or periodically provides the user state information to the electronic device 100.

The electronic device 100 obtains the current environment information and/or user state information, and determines that the audio data of the first application (the second application) is in the Bluetooth device 1 (Bluetooth device 1 (Bluetooth device) based on the correspondence between the environment information, the user state information, and the output volume. 2) on the output volume.

Correspondingly, in step S106, the electronic device 100 sends the first command and the audio data of the first application to the Bluetooth device 1, and the electronic device 100 also sends the output volume to the Bluetooth device 1; the first command is used to instruct the Bluetooth device 1 to use the output volume. The volume outputs audio data of the first application. In this embodiment of the present application, the output volume may also be referred to as the first volume.

Similarly, in step S111, the electronic device 100 sends the second command and the audio data of the first application to the Bluetooth device 2, and the electronic device 100 also sends the output volume to the Bluetooth device 2; the second command is used to instruct the Bluetooth device 2 to use this The output volume outputs audio data of the first application.

In some embodiments, the electronic device 100 may also determine the audio output duration based on the user's navigation/track information. When the user is driving, the electronic device 100 obtains the start time and the expected end time of the current navigation/track information, and determines the time or duration of the audio output. Correspondingly, in step S106, the electronic device 100 sends the first command and the audio data of the first application to the Bluetooth device 1, and the electronic device 100 also sends the output time or duration to the Bluetooth device 1; the first command is used to indicate the Bluetooth device 1. The audio data of the first application is output at the output time or duration.

Similarly, in step S111, the electronic device 100 sends the second command and the audio data of the first application to the Bluetooth device 2, and the electronic device 100 also sends the output time or duration to the Bluetooth device 1; the second command is used to instruct the Bluetooth device 2 The audio data of the second application is output at the output time or duration.
