Description

Technical Field

[0001] The present application relates to the field of Bluetooth communications, and more specifically, to a Bluetooth audio playback method, electronic device, and storage medium. Background Art

[0002] When existing mobile phone applications use Bluetooth devices to play audio, audio data and audio status control commands are transmitted using two protocols. Audio status control commands are transmitted using the Audio / Video Remote Control Profile (AVRCP), while audio data is transmitted using the Audio / Video Distribution Transport Protocol (AVDTP). Typically, on Android, applications can only transmit audio status via AVRCP after registering for a multimedia session. However, the current situation is that applications registered with Mediasession can send audio data through AVDTP and transmit audio status control instructions through AVRCP. However, applications not registered with Mediasession can only send audio data through AVDTP and cannot transmit audio status control instructions through AVRCP. As a result, the audio status control instructions sent to Bluetooth devices by applications registered with Mediasession and applications not registered with Mediasession are inconsistent, causing Bluetooth devices to be incompatible with applications registered with Mediasession and applications not registered with Mediasession, resulting in playback anomalies when Bluetooth devices play audio data from applications not registered with Mediasession. For example, a mobile phone music player application registered with Mediasession sends audio status control instructions to a Bluetooth device, and the Bluetooth device can receive the audio status control instructions sent by the mobile phone music player application to control the played audio data. However, when a Bluetooth device is connected to a car audio application that has not registered with Mediasession, the car audio application cannot send audio status control instructions to the Bluetooth device, making it impossible for the Bluetooth device to play the audio data of the car audio application. Summary of the Invention

[0029] To facilitate the description of each embodiment below, a brief description of the user interface (UI) involved in the embodiments of the present application is first given. UI is a medium interface for interaction and information exchange between an application or operating system and a user, which can realize the conversion between the internal form of information and the form acceptable to the user. The user interface of an application is a source code written in a specific computer language such as JAVA and extensible markup language (XML). The interface source code is parsed and rendered on an electronic device, and finally presented as content that the user can recognize, such as pictures, text, buttons and other controls. Controls are the basic elements of the user interface. Typical controls include buttons, widgets, toolbars, menu bars, text boxes, scroll bars, images and text. The properties and contents of controls in the interface are defined by tags or nodes, such as XML through <textview> 、 <imgview> 、 <videoview>The controls contained in the interface are specified by nodes such as <head> and <body>. A node corresponds to a control or attribute in the interface, and the node is presented as user-visible content after parsing and rendering. In addition, many applications, such as hybrid applications, usually also contain web pages in their interfaces. A web page, also known as a page, can be understood as a special control embedded in the application interface. A web page is a source code written in a specific computer language, such as hypertext markup language (HTML), cascading style sheets (CSS), JAVA scripts (JavaScript, JS), etc. The web page source code can be loaded and displayed as user-recognizable content by a browser or a web page display component with similar functions to a browser. The specific content contained in a web page is also defined by tags or nodes in the web page source code, such as HTML through <body>. 、 、 <video> 、 <canvas>To define the elements and attributes of a web page.

[0030] A common form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operations that uses graphics to display. It can be an icon, window, control, or other interface element displayed on the display of an electronic device.

[0031] When an existing audio application or video application plays audio data, it creates a Track in the audio management system in the audio framework layer. The number of Tracks can be controlled by the audio application or video application. Figure 1A-1B , which is a schematic diagram of an electronic device playing audio data stream and audio status in one embodiment of the present application.

[0032] Figure 1A Schematic diagram of the audio data stream and audio status played by an application registered with Mediasession in an electronic device. In this embodiment, when playing a Track audio track, the audio management system of the application registered with Mediasession sends audio data to the Bluetooth device through the Audio / Video Distribution Transport Protocol (AVDTP) for transmission between Bluetooth devices, and sends audio status control instructions to the Bluetooth device through the Audio / Video Remote Control Profile (AVRCP). For example, when transmitting audio data, the application registered with Mediasession sends a play instruction T1 to the Bluetooth device through AVRCP or sends a pause instruction T2 to the Bluetooth device through AVRCP.

[0033] Figure 1B This diagram illustrates the audio data stream and audio status of an unregistered Mediasession application in an electronic device. In this embodiment, when playing a Track, the audio management system of an unregistered Mediasession application only sends audio data to the Bluetooth device via AVDTP and cannot send audio status control instructions to the Bluetooth device via AVRCP. This results in inconsistent audio status and audio data streams when the electronic device plays audio data from different applications, causing playback anomalies on the Bluetooth device.

[0034] In view of this, the present application provides a Bluetooth audio playback method to keep the audio data and audio status consistent. The Bluetooth audio playback method is applied in the electronic device 100. Figure 2 , which is a software structure block diagram of the electronic device 100 in one embodiment of the present application. The layered architecture divides the software into the application layer, application framework layer, hardware abstraction layer (HAL), and kernel layer from top to bottom.

[0035] The application layer can include a series of application packages. Figure 2 As shown, the application package may include an audio application or a video application.

[0036] The application framework layer provides an application programming interface (API) and programming framework for applications in the application layer. The application framework layer includes some predefined functions. As shown in Figure 1, the application framework layer can include a Bluetooth framework layer and an audio framework layer.

[0037] The hardware abstraction layer provides a unified access interface for different hardware devices. Figure 2 As shown, the HAL may include a Bluetooth protocol stack.

[0038] The kernel layer is the layer between hardware and software. The kernel layer includes at least various drivers, e.g. Figure 2 The Bluetooth driver shown.

[0039] refer to Figure 3 , which is an application environment diagram of a Bluetooth audio playback method in an embodiment of the present application. The Bluetooth audio playback method is applied in an electronic device 100. The electronic device 100 is communicatively connected to a Bluetooth device 200 via a Bluetooth communication module. In one embodiment, the electronic device 100 includes, but is not limited to, a smartphone, a laptop, a desktop, a handheld PC, a personal digital assistant, an embedded processor, a digital signal processor (DSP), a graphics device, a video game device, a set-top box, a microcontroller, a cellular phone, a portable media player, a handheld device, a wearable device (e.g., display glasses or goggles, a head-mounted display (HMD), a watch, a head-mounted device, an armband, jewelry, etc.), a virtual reality (VR) and / or augmented reality (AR) device, an Internet of Things (IoT) device, a smart audio system, an in-vehicle infotainment device, a streaming client device, an e-book reading device, a POS machine, a control system for an electric vehicle, and various other electronic devices. In one embodiment, the Bluetooth device 200 includes a Bluetooth device with Bluetooth audio playback capability, such as a Bluetooth headset and a Bluetooth speaker.

[0040] Please refer to Figure 4 FIG. 1 is a flow chart of a Bluetooth audio playback method according to an embodiment of the present invention. The method comprises the following steps.

[0041] Step S401: An application at the application layer obtains audio data according to a play command.

[0042] In this embodiment, the application of the application layer includes an audio application or a video application. The following describes the Bluetooth audio playback method provided by this application by taking the application as a music player, the electronic device 100 as a mobile phone, and the Bluetooth device 200 as a Bluetooth headset as an example.

[0043] refer to Figure 5 As shown, when the user clicks the play / pause button 51 on the music player interface 50 of the mobile phone, the music player generates a play command in response to the user's operation of clicking the play / pause button 51 on the music player interface 50. The music player obtains audio data according to the play command.

[0044] Step S402: The audio manager of the audio framework layer obtains a play or pause command from the application, creates a Track audio track of the audio data according to the play or pause command, and determines the number of Track audio tracks.

[0045] In this embodiment, the determination of the number of Track tracks includes: the audio manager deleting the Track track when determining that the playback of the audio data has ended. In this embodiment, the Track track is created when the audio data is acquired; and the Track track is deleted when the audio data has finished playing. For example, when the music player of a mobile phone acquires a play command for a song, the audio manager of the audio framework layer creates the Track track, and when the music player finishes playing the audio data of the song, the audio manager of the audio framework layer deletes the Track track.

[0046] In one embodiment, determining the number of Track tracks includes: the audio manager obtaining a pause command from the application, and deleting the Track track according to the pause command. Figure 5 When the user clicks the play / pause button 51 on the music player interface 50 of the mobile phone, the music player generates a pause command in response to the user clicking the play / pause button 51 on the music player interface 50. The audio manager obtains the pause command from the music player and deletes the Track audio track according to the pause command.

[0047] In one embodiment, determining the number of Track audio tracks includes: in response to an operation of switching the audio data of a first playback scene of an audio application or a video application to the audio data of a second playback scene, deleting the Track audio track of the audio data of the first playback scene, and creating a Track audio track of the audio data of the second playback scene, wherein the audio data of the first playback scene is discontinuous with the audio data of the second playback scene.

[0048] For example, reference Figure 6 As shown, the music playback interface 50 includes a previous button 52 and a next button 53, wherein the audio data of the currently playing music is the audio data of the first playback scene, and the audio data of the music played by the previous button 52 or the next button 53 is the audio data of the second playback scene. When the user clicks the previous button 52 or the next button 53 on the music playback interface 60 of the mobile phone's music player, the audio manager responds to the user's operation of clicking the previous button 52 or the next button 53 on the music playback interface 50, deletes the Track of the audio data of the currently playing music, and creates the Track of the audio data of the music played by the previous button 52 or the next button 53. The audio data of the currently playing music is not continuous with the audio data of the music played by the previous button 52 or the next button 53.

[0049] Step S403: The Hal layer obtains the number of Track audio tracks from the audio framework layer.

[0050] In one embodiment, the audio manager generates Track track quantity update information when creating a Track track or deleting a Track track, and the audio framework layer sends the Track track quantity update information to the Hal layer. The Hal layer obtains the Track track quantity update information sent by the audio framework layer to determine the number of Track tracks.

[0051] Step S404: The Hal layer determines whether the number of Track audio tracks is increased or decreased according to the number of Track audio tracks.

[0052] In this embodiment, if it is determined that the number of Track tracks is increased, step S405 is executed; otherwise, if it is determined that the number of Track tracks is decreased, step S406 is executed.

[0053] Step S405: The Hal layer determines that the audio state of the audio data is playing, and sends the playing audio state to the Bluetooth protocol stack of the Hal layer.

[0054] In one embodiment, the Hal layer determines that the audio status of the audio data is playing, and sends the playing audio status to the Bluetooth protocol stack of the Hal layer, including: when it is determined that the number of the Track audio track changes from 0 to 1, the Hal layer determines that the audio status of the audio data is playing, and sends the playing audio status to the Bluetooth protocol stack of the Hal layer.

[0055] Step S406: The Hal layer determines that the audio state of the audio data is paused, and sends the paused audio state to the Bluetooth protocol stack of the Hal layer.

[0056] In one embodiment, the Hal layer determines that the audio state of the audio data is paused, and sends the paused audio state to the Bluetooth protocol stack of the Hal layer, including: when the Hal layer determines that the number of Track audio tracks changes from 1 to 0, the paused audio state is sent to the Bluetooth protocol stack.

[0057] In step S407, the Bluetooth protocol stack sends a play instruction to the Bluetooth device 200 according to the audio state of the playing audio, or sends a pause instruction to the Bluetooth device 200 according to the audio state of the paused audio. The play instruction is used to set the audio state of the Bluetooth device 200 to the play state, and the pause instruction is used to set the audio state of the Bluetooth device 200 to the pause state.

[0058] In this embodiment, the Bluetooth protocol stack sends a play instruction or a pause instruction to the Bluetooth device 200 through AVRCP.

[0059] In this application, when the Hal layer detects that the number of Track audio tracks increases by one, a play instruction is sent to the Bluetooth device through the Bluetooth protocol stack to set the audio state of the Bluetooth device to play, and when the Hal layer detects that the number of Track audio tracks decreases by one, a pause instruction is sent to the Bluetooth device through the Bluetooth protocol stack to set the audio state of the Bluetooth device to pause, thereby avoiding abnormal playback problems of the Bluetooth device due to chaotic audio state management of different applications.

[0060] It should be noted that, in another embodiment of the present application, after the Hal layer obtains the number of Track tracks from the audio framework layer, it sends the number of Track tracks to the Bluetooth protocol stack. When the Bluetooth protocol stack determines that the number of Track tracks has increased based on the number of Track tracks, it determines that the audio state of the audio data is playing, and sends a play instruction to the Bluetooth device 200 based on the playing audio state; when the Bluetooth protocol stack determines that the number of Track tracks has decreased based on the number of Track tracks, it determines that the audio state of the audio data is paused, and sends a pause instruction to the Bluetooth device 200 based on the paused audio state.

[0061] The electronic device 100 involved in the embodiment of the present application is introduced below. Figure 7 , which is a schematic diagram of the hardware structure of an electronic device 100 in an embodiment of the present application.

[0065] The controller can generate operation control signals according to the instruction operation code and timing signal to complete the control of instruction fetching and execution.

[0066] Processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in processor 110 is a cache memory. This memory can store instructions or data that have just been used or are being recycled by processor 110. If processor 110 needs to use the same instruction or data again, it can directly access the memory. This avoids duplicate accesses, reduces processor 110 latency, and thus improves system efficiency.

The processor 110 may be coupled to the touch sensor 180K, the charger, the flash, the camera 193, and the like via different I2C bus interfaces. For example, the processor 110 may be coupled to the touch sensor 180K via the I2C interface, enabling communication between the processor 110 and the touch sensor 180K via the I2C bus interface, thereby implementing the touch function of the electronic device 100.

[0069] The I2S interface can be used for audio communication. In some embodiments, the processor 110 can include multiple I2S buses. The processor 110 can be coupled to the audio module 170 via the I2S bus to enable communication between the processor 110 and the audio module 170. In some embodiments, the audio module 170 can transmit audio signals to the wireless communication module 160 via the I2S interface, enabling the function of answering calls through a Bluetooth headset.

[0070] The PCM interface can also be used for audio communication, sampling, quantizing, and encoding analog signals. In some embodiments, the audio module 170 and the wireless communication module 160 can be coupled via a PCM bus interface. In some embodiments, the audio module 170 can also transmit audio signals to the wireless communication module 160 via the PCM interface, enabling the function of answering calls via a Bluetooth headset. Both the I2S interface and the PCM interface can be used for audio communication.

[0071] The UART interface is a universal serial data bus used for asynchronous communication. This bus can be a bidirectional communication bus. It converts the data to be transmitted between serial communication and parallel communication. In some embodiments, the UART interface is typically used to connect the processor 110 and the wireless communication module 160. For example, the processor 110 communicates with the Bluetooth module in the wireless communication module 160 via the UART interface to implement Bluetooth functionality. In some embodiments, the audio module 170 can transmit audio signals to the wireless communication module 160 via the UART interface, enabling the function of playing music through Bluetooth headphones.

[0072] The MIPI interface can be used to connect the processor 110 to peripheral devices such as the display 194 and the camera 193. MIPI interfaces include the camera serial interface (CSI) and the display serial interface (DSI). In some embodiments, the processor 110 and the camera 193 communicate via the CSI interface to implement the camera function of the electronic device 100.
