[0032] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present disclosure.

[0033] The audio switching method provided by the present disclosure is applied to the scenario where an electronic device is connected to an external audio playback device for audio playback. When using an electronic device for audio playback, it is often necessary to connect an external device to meet the user's usage needs. When an electronic device runs an audio playback program for audio playback, it is usually necessary to assign audio playback permissions to the corresponding audio playback application. When using an electronic device to make calls and switch between audio playback applications, the audio playback permissions of the electronic device will be transferred, and the connection status with the external device and the audio playback mode will change. Because the transfer of audio playback permissions is usually faster than the change of the connection status of the external device and the audio playback mode, switching between calls and audio playback applications at this time may cause the sound on the electronic device to be played externally.

[0034] The electronic devices in the embodiments of the present disclosure include mobile phones, computers, televisions and other electronic devices that can be connected to external devices for audio playback. The external devices include LAN connection devices, wired connection devices, Bluetooth connection devices and other external devices, such as Bluetooth headsets, wired headsets, etc.

[0035] For example, when a mobile phone is connected to a Bluetooth headset and an audio and video playback application is used, the audio playback permission will be occupied, and the connection status between the mobile phone and the Bluetooth headset will change to the A2DP (Advanced Audio Distribution Profile, Bluetooth audio transmission model protocol) state. At this time, if a call is received, the audio playback permission will be transferred to the call application when answering the call, and the connection status between the mobile phone and the Bluetooth headset will change to the SCO (Synchronous Connection Oriented link, connection-oriented synchronous link, usually used for voice data transmission) state. When the call is over, the system of the electronic device will automatically transfer the music playback permission to the previously used audio and video playback program, and switch the connection status and audio mode to the corresponding state of audio playback. However, due to the system's own processing method, the music playback permission is transferred to the previously used audio and video playback program before the connection status and audio mode are switched, and because there is a time interval in the process of switching the connection status from SCO to A2DP and the audio mode has not been switched, the sound will be emitted from the mobile phone instead of from the external Bluetooth headset, resulting in the phenomenon of external sound.

[0036] In view of this, the present disclosure proposes an audio switching method, device and storage medium. The connection status between the electronic device and the external device and the audio mode playback status are determined when the audio playback permission is released after the voice call of the electronic device ends, and then the audio playback permission is transferred. The audio playback permission is transferred after the connection status and the audio mode playback status are switched, thereby solving the problem of external sound caused by the too fast transfer of audio playback permission.

[0037] The following describes how to switch audio.

[0038] Figure 1 is a flow chart of an audio switching method according to an exemplary embodiment. Figure 1 As shown, the audio switching method is used in an electronic device and includes the following steps.

[0039] In step S11, in response to the electronic device releasing the audio play permission when a call ends, the connection state of an external play device of the electronic device and the audio mode play state are determined.

[0040] In the disclosed embodiment, the audio playback permission is the permission allowed by the electronic device system to play audio, and the audio and video playback application needs to obtain the audio playback permission to play audio. During a call, the call application will occupy the audio playback permission, and when the call ends, the audio playback permission will be released, at which time the audio playback permission can be occupied again. The connection status of the external playback device of the electronic device has different corresponding connection states according to different external playback devices and different applications. The audio mode playback state may also have different audio mode playback states corresponding to different applications.

[0041] In step S12, based on the connection state and the audio mode play state, the audio play permission is sent to the first application running on the electronic device, where the first application is the application that holds the audio play permission before the electronic device executes the call.

[0042] In the disclosed embodiment, the audio playback permission is released after the call is over and is not occupied by other applications. After determining the connection status and the audio mode playback status, the electronic device system will send the music playback permission to the application that occupied the audio playback permission before the call, thereby avoiding the phenomenon of external sound playback caused by the system sending the music playback permission before the connection status and the audio mode playback status are switched.

[0043] In one implementation, when a call on an electronic device ends, the audio playback permission is released, and the electronic device system determines the connection status of an external playback device of the electronic device and the audio mode playback status, and makes a judgment based on the connection status and the audio mode playback status to decide whether to send the audio playback permission to the application before the call to achieve audio switching.

[0044] Figure 2 The invention is a flowchart showing delayed audio switching according to an exemplary embodiment.

[0045] In step S21, in response to the electronic device releasing the audio play permission when a call ends, the connection state of an external play device of the electronic device and the audio mode play state are determined.

[0046] In the embodiment of the present disclosure, step S21 is the same as step S11 in the above embodiment, so it will not be described again.

[0047] In step S22, if the connection state is a call connection state, and the audio mode playing state is a call playing state, then sending the audio playing permission to the first application running on the electronic device is delayed.

[0048] In the embodiment of the present disclosure, if the connection state is a call connection state, and the audio mode playback state is a call playback state, it means that the connection state and the audio mode playback state have not switched to the state required by the audio playback application. Therefore, it is necessary to delay sending the audio playback permission to the audio playback application to avoid the phenomenon of external sound playback.

[0049] In one embodiment, when a call of the electronic device ends, if the connection state is the call connection state and the audio mode playback state is the call playback state, the audio playback permission cannot be transferred. The sending of the audio playback permission can be delayed so that the transfer of the audio playback permission is after the switching of the connection state and the audio mode playback state, thereby avoiding the phenomenon of external sound playback.

[0050] In the above embodiment, it is mentioned that the phenomenon of sound being played outward can be avoided by delaying the sending of audio playback permission. The following describes the process of how to delay the sending of audio playback permission to achieve delayed audio switching.

[0051] Figure 3 The invention is a flowchart showing a method of delaying the sending of audio playing permission according to a delay time according to an exemplary embodiment.

[0052] In step S31, after delaying according to the delay time, the connection status and the audio mode playing status are determined.

[0053] In the embodiment of the present disclosure, the delay time is a fixed time duration pre-set according to actual needs. Determining the connection state and the audio mode playing state is to determine the connection state and the audio mode playing state after delaying the sending of the audio playing permission.

[0054] In step S32, if the connection state is an audio playing connection state, and the audio mode playing state is a state of playing the audio of the first application, an audio playing permission is sent to the first application running on the electronic device.

[0055] In the disclosed embodiment, if the connection state is an audio playback connection state, and the audio mode playback state is a state of playing the audio of the first application, the transfer of audio playback authority by the electronic device system will not cause the electronic device to produce sound externally.

[0056] In one implementation, after releasing the audio playback permission in response to the end of a call, the sending of the audio playback permission is delayed according to a preset delay time. After the delay, the connection status and the audio mode playback status are determined. If the connection status is the audio playback connection status, and the audio mode playback status is the status of playing the audio of the audio playback program before the call, the system sends the audio playback permission to the audio of the audio playback program before the call. By setting the delay time for delay, the phenomenon of sound being played outward can be prevented.

[0057] Sometimes after the delay time, the connection status and audio mode playback status may not be switched. In this case, it is necessary to delay sending the audio playback permission to avoid the sound being played out. The following will explain how to delay sending the audio playback permission once or multiple times.

[0058] Figure 4 The invention is a flowchart showing one or more delayed sending of audio playing permission according to an exemplary embodiment.

[0059] In step S41, at the i-th delay, after delaying for the i-th delay time, the connection state and the audio mode playing state are determined, where i is a positive integer greater than or equal to 1.

[0060] In the disclosed embodiment, determining the connection status and the audio mode playing status is to judge the connection status and the audio mode playing status after the i-th delayed sending of the audio playing permission to determine the subsequent processing. The i-th delay time is obtained by repeated test experience and is preset in the electronic device system.

[0061] In step S42, if the connection state is a call connection state or the audio mode playback state is a call playback state, an (i+1)th delay is performed.

[0062] In the disclosed embodiment, if the connection state is a call connection state, or the audio mode playback state is a call playback state, sending the audio playback permission at this time will cause the sound to be played outward, so a delay is required.

[0063] In step S43, during the i+1th delay, after delaying for the i+1th delay time, the connection status and the audio mode playback status are repeatedly determined until the connection status is the audio playback connection status, and the audio mode playback status is the status of playing the first application audio, and the duration corresponding to the i+1th delay time is less than the duration corresponding to the i-th delay time.

[0064] In the disclosed embodiment, the connection state is the audio playback connection state, and the audio mode playback state is the state of playing the audio of the first application, which means that the connection state and the audio mode playback state have both switched to the state of the corresponding application for audio playback. At this time, the transfer of audio playback authority will not cause the sound to be played out, and no delay is required. The delay time of each delay is less than the delay time of the previous delay.

[0065] In step S44, if the connection state is an audio playback connection state, and the audio mode playback state is a state of playing the audio of the first application, an audio playback permission is sent to the first application running on the electronic device.

[0066] In the disclosed embodiment, the state of playing the audio of the first application is determined by the system and the first application, and the corresponding audio mode playback state is determined according to the corresponding state when the first application is running. The audio playback permission is sent by the electronic device system. If the connection state is the audio playback connection state, and the audio mode playback state is the state of playing the audio of the first application, it means that the requirements for sending the audio playback permission are met. At this time, the audio playback permission is sent to the first application running on the electronic device to avoid the phenomenon of external sound.

[0067] In one implementation, when the sending of audio playback permission is delayed, after a certain delay, it is determined whether the connection state and the audio mode playback state meet the conditions. If the connection state is a call connection state or the audio mode playback state is a state of playing a call, it means that the conditions are not fully met, and the next delay will be performed at this time. Among them, the delay time of the next delay is less than the delay time of the delay of this delay. If after the next delay, the connection state is a call connection state or the audio mode playback state is a state of playing a call, the above delay process is repeated, and the next delay is performed again until the connection state and the audio mode playback state are switched to the state corresponding to the audio playback. After determining that the connection state and the audio mode playback state are switched to the state corresponding to the audio playback, the electronic device system sends the audio playback permission to the application running before the call, thereby avoiding the phenomenon of sound being played outward. In the above-mentioned delayed sending of audio playback permission, by setting shorter and shorter delay times, the delay time before sending the audio playback permission can be minimized to improve the user experience.

[0068] In one implementation, if the audio mode playback state corresponding to the first application is the same as during a call, there is no need to wait for the audio mode playback state to switch after the call ends, and the audio playback permission is sent to the first application after determining that the connection state has switched.

[0069] In one implementation, if the connection state corresponding to the first application is the same as that during the call, there is no need to wait for the connection mode to switch after the call ends, and the audio playback permission is sent to the first application after determining that the audio mode playback state has switched.

[0070] In one implementation, if the connection status and audio mode playback status corresponding to the first application are the same as during a call, the audio playback permission is directly sent to the first application.

[0071] In one implementation of the audio switching method provided by the present disclosure, in the process of delaying the sending of audio playback permission, when the number of delays reaches a delay number threshold, the audio playback permission is sent to the first application running on the electronic device after the delay ends.

[0072] In the disclosed embodiment, the delay times threshold is a preset threshold value, which is determined by the empirical value of repeated tests. By presetting the delay times threshold value, it is possible to avoid the audio mode playback state and the connection state not switching normally due to the system or the electronic device hardware, thereby avoiding excessive delays and affecting the user experience. The audio playback permission is sent by the electronic device system.

[0073] In one implementation, during the process of delaying the audio playback permission, if the number of delays reaches a preset delay number threshold, after the delay ends, no further delay will be performed, and the system will send the audio playback permission to the first application.

[0074] In one implementation, during the process of delaying the audio playback permission, if the number of delays reaches a preset delay threshold, after the delay ends, the audio mode playback status and connection status will no longer be judged, and the system will send the audio playback permission to the first application.

[0075] In one implementation of the audio switching method provided by the present disclosure, if the connection state is an audio playback connection state, and the audio mode playback state is a state of playing the audio of the first application, an audio playback permission is sent to the first application running on the electronic device.

[0076] In one embodiment, after the call is over, it is determined whether the connection status between the electronic device and the external device and the audio mode playback status have been switched accordingly. If the connection status is an audio playback connection status, and the audio mode playback status is a status of playing the audio of the first application, the system sends the audio playback permission to the first application running on the electronic device to switch the audio. Sending the audio playback permission at this time can avoid the phenomenon of external sound playback.

[0077] In one implementation of the audio switching method provided by the present disclosure, in response to a second application of the electronic device requesting audio playback permission, the audio playback permission is sent to the second application running on the electronic device, where the second application is an application other than the first application.

[0078] In the disclosed embodiment, sending the audio playback permission to the second application is an operation before sending the audio playback permission to the first application, and there is no delay. The second application requests the audio playback permission, and the audio playback permission is sent to the second application running on the electronic device without delay, thereby increasing the speed of system switching applications, preventing system freezes caused by delays, and improving user experience.

[0079] In one implementation, after the call ends, if the connection status between the electronic device and the external device and the audio mode playback status have completed the corresponding switching, there is no need to delay sending the audio playback permission to the first application, i.e., the application running before the call. Before sending the audio playback permission to the first application, if a new application requests the audio playback permission at this time, the system sends the audio playback permission to the new application requesting the audio playback permission, and the new application, i.e., the second application, performs the audio playback.

[0080] In one implementation, after the call ends, if the connection status between the electronic device and the external device and the audio mode playback status have not completed the corresponding switching, it is necessary to delay sending the audio playback permission. If a new application requests the audio playback permission at this time, the system sends the audio playback permission to the new application requesting the audio playback permission, and the new application, i.e., the second application, performs the audio playback.

[0081] In one implementation of the audio switching method provided by the present disclosure, electronic device calls include calls initiated by an application and calls initiated by the electronic device's own call program, the external playback device of the electronic device is a Bluetooth external device, the connection state is a Bluetooth connection state, and the first application is an audio and video playback application.

[0082] In one implementation, the electronic device call may also include a call initiated by a default call application of the electronic device system or a third-party call application. The external playback device may include a Bluetooth external device, a wired connection device, a local area network external device, etc. When the electronic device is connected to the external playback device, audio playback is performed from the external playback device. The connection status is jointly determined by the external device, the electronic device system, and the running application, including a wireless connection status, a wired connection status, etc.

[0083] In one implementation, when the connection state is a Bluetooth connection state, the call connection state may be a SCO connection state, and the audio playback connection state may be an A2DP connection state. Which Bluetooth connection state to use is determined by the Bluetooth external device, the electronic device system, and the running application.

[0084] In the embodiments of the present disclosure, the audio switching method involved in the above embodiments is described below by taking the electronic device as a mobile phone terminal and the external device as a Bluetooth headset as an example.

[0085] Figure 5 The present invention is a flowchart of performing audio switching according to an exemplary embodiment.

[0086] In one embodiment, if Figure 5As shown, when using a Bluetooth headset, in response to the end of a call, the audio focus is released, and it is determined whether the Bluetooth is in a call. Among them, the audio focus is the audio playback permission occupied by the application. Determining whether the Bluetooth is in a call is to determine whether it is the Bluetooth connection state and audio mode playback state corresponding to the call state. If the Bluetooth is not in a call, it means that the Bluetooth connection state and the audio mode playback state have been set to the audio playback state corresponding to the audio and video playback application, and the system will allocate the audio focus to the audio and video playback application. At this time, the Bluetooth headset can normally perform the audio playback of the corresponding audio and video playback application, and the sound will not be played out. If the Bluetooth is still in a call, it means that the Bluetooth connection state and the audio mode playback state have not been fully set, and the system will delay the allocation of the audio focus. If a new application makes a new audio focus application during the delay time, the system will process the new application normally, that is, the audio focus is allocated to the new application. If there is no new application to apply for audio focus and the single delay ends, the relevant state will be judged. Among them, the relevant state includes the Bluetooth connection state, the audio mode playback state, and the delay number state. If the Bluetooth and audio mode are not set, that is, the Bluetooth connection state and the audio mode playback state have not completed the corresponding settings, the above-mentioned delayed allocation of audio focus process is repeated. If the Bluetooth and audio modes are set up, that is, the Bluetooth connection status and the audio mode playback status are set up accordingly, the system will assign the audio focus to the corresponding audio and video playback application to complete the audio switching. Among them, when the delay times are equal to the preset delay times threshold, after this delay ends, there is no need to determine whether the Bluetooth and audio modes are set up, and the system will assign the audio focus to the corresponding audio and video playback application.

[0087] Through the audio switching method in the above embodiment, after the corresponding settings of the Bluetooth connection state and the audio mode playback state are completed, the audio playback permission is sent to avoid the phenomenon of external sound when the call and the application transfer the audio playback permission. By setting multiple delays with different delay times, the delay time is minimized to improve the user experience. And set a preset delay number threshold to prevent system or hardware problems from making the Bluetooth connection state and the audio mode playback state unable to complete the corresponding settings, and avoid the situation of no response causing the delay state.

[0088] Based on the same concept, an embodiment of the present disclosure also provides an audio switching device.

[0089] It is understandable that in order to realize the above functions, the audio switching device provided by the embodiment of the present disclosure includes hardware structures and / or software modules corresponding to the execution of each function. In combination with the units and algorithm steps of each example disclosed in the embodiment of the present disclosure, the embodiment of the present disclosure can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the technical solution of the embodiment of the present disclosure.

[0090] Figure 6 FIG. 1 is a block diagram of an audio switching device according to an exemplary embodiment. Figure 6 , the device includes a detection unit 101 and a processing unit 102.

[0091] The detection unit 101 is configured to determine the connection status of an external playback device of the electronic device and the audio mode playback status in response to the electronic device releasing the audio playback permission when a call ends.

[0092] The processing unit 102 is configured to send audio playback permission to a first application running on the electronic device based on the connection status and the audio mode playback status; the first application is an application that holds the audio playback permission before the electronic device executes a call.
