Among them, common audio playback devices include car music players, speakers, and headphones.

According to different connection methods, audio playback devices can be divided into wired audio playback devices and wireless audio playback devices. The electronic device can interact with the wireless audio playback device through a wireless network to transmit signals. The wireless network may be Bluetooth. , Wifi, LTE network or NFC, etc.

Exemplarily, as shown in FIG. 1, a block diagram of a voice system 1 provided by an embodiment of the present application is shown. Specifically, the voice system 1 includes an electronic device 100, a first wireless audio playback device 210, and a second wireless audio playback device 220. The electronic device 100 can be connected to the first wireless audio playback device 210 and the second wireless audio playback device 220 at the same time. .

In the embodiment of the present invention, an application capable of playing audio is installed in the electronic device 100. Specifically, the application may be audio playing software, video playing software, or calling software. The electronic device 100 sends the audio to be played to the first wireless audio playback device 210 or the second wireless audio playback device 220, and the first wireless audio playback device 210 or the second wireless audio playback device 220 plays the voice.

In the embodiment of the present invention, the first wireless audio playback device 210 and the second wireless audio playback device 220 may both be Bluetooth speakers or Bluetooth headsets. The first wireless audio playback device 210 and the second wireless audio playback device 220 may be enabled with the Bluetooth function. A connection with the electronic device 100 is achieved, and after the connection is established, the electronic device 100 sends the voice that it needs to play to the Bluetooth audio, and the Bluetooth audio implements voice playback.

When the first wireless audio playback device 210 and the second wireless audio playback device 220 are both Bluetooth devices, the electronic device 100 can be connected to the first wireless audio playback device 210 and the second wireless audio playback device 220 through the Bluetooth module at the same time. In an implementation manner, the Bluetooth module in the electronic device may support multipoint connection, so that the electronic device shown in FIG. 1 can be connected to the first wireless audio playback device 210 and the second wireless audio playback device 220, respectively. After the connection, the electronic device 100 can obtain the identities of the first wireless audio playback device 210 and the second wireless audio playback device 220, and the identifications may be MAC addresses. Specifically, when the Bluetooth function of the electronic device is turned on, the electronic device scans the Bluetooth devices within a certain distance from the surrounding area. Specifically, after receiving the scan command from the electronic device's Bluetooth chip or other underlying network module, the preset Scan in the order of channel scanning. For example, scan the common channels 1, 7, and 13 first, and then scan the other unused channels, so as to obtain the identification of all Bluetooth devices in the current range and display them in the Bluetooth list interface of the electronic device. .

If there is a connected Bluetooth device with a better signal strength in the scanned Bluetooth device identification, the electronic device will automatically connect with the Bluetooth device, and the user can also select a Bluetooth device in the Bluetooth list interface to connect.

When the electronic device is connected to an external Bluetooth device, the system of the electronic device obtains a status value, which indicates that the electronic device is currently connected to the Bluetooth device. Therefore, the electronic device can detect the Bluetooth device that has been connected, thereby obtaining the device identification of the Bluetooth device.

Therefore, the electronic device 100, The first wireless audio playback device 210 and the second wireless audio playback device 220 are connected at the same time through networking, that is, the first wireless audio playback device 210 serves as a repeater of the electronic device 100 and the second wireless audio playback device 220.

Therefore, after the electronic device 100 is connected to the first wireless audio playback device 210 and the second wireless audio playback device 220 at the same time, different audio playback devices can play different audio data. Of course, it can also be played by different audio playback devices. Same audio data to achieve effects like stereo. It is also possible to use one of the wireless audio playback devices to play audio data while the other wireless audio playback device is on standby without playing audio.

However, the inventor found in research that if one wireless audio playback device is switched to another wireless audio playback device and the other wireless audio playback device does not have audio data to play at this time, the electronic device is required to send the audio data To the wireless audio playback device, the audio data transmission process and decoding process need to take a certain amount of time, because if it is played inside after switching, it may cause another wireless audio playback device because the audio data has not been acquired or has not yet been acquired. If the decompression is complete, and it cannot be played, a freeze phenomenon will occur, which will affect the user experience.

Therefore, in order to solve the above technical defects, an embodiment of the present application provides an audio playback method, which is applied to the above-mentioned electronic device. Specifically, please refer to FIG. 3, which illustrates an audio playback method provided by an embodiment of the present application. A schematic flowchart of the method includes: S301 to S304.

S301: When it is detected that the electronic device is playing audio data through the first wireless audio playback device, determine whether a switching instruction is obtained.

The electronic device is connected to the first wireless audio playback device and the second wireless audio playback device at the same time. When the user plays audio data, the user can select the music to be played on the audio playback interface of the electronic device, as shown in Figures 1 and 2. The displayed interface of the electronic device shown below, select one or more audio data, and click the play button to play the selected audio data. In addition, the user can also select a wireless audio playback device for playing audio data through the electronic device.

For example, as shown in FIG. 4, a device management interface of an electronic device is shown. In the device management interface, an operation interface of two wireless audio playback devices connected to the electronic device is displayed, and specifically includes two wireless audio playback devices. A device selection button, which is a selection button corresponding to each device in FIG. 4, for example, when the round button is on the left, the electronic device selects a wireless audio playback device to play audio data. After the connection is established, the audio data played by the electronic device can play the audio data through the connected wireless audio playback device.

In addition, in this interface, each wireless audio playback device also corresponds to a drop-down menu. The user can use the drop-down menu to configure the user's audio playback application for the wireless audio playback device. For example, configure the first application for device 1 as Device 2 is configured with a second application program, and if the electronic device can control the first application program to play the first audio data and control the second application program to play the second audio data, the device 1 can cause the device 1 to play the first application program. The first audio data causes the device 2 to play the second audio data of the second application.

Therefore, whether the electronic device is connected to the first wireless audio playback device can be determined through the button status in the interface. In addition, whether the device connected by the electronic device through Bluetooth is an audio playback device can be detected. In an electronic device, the type of the device currently connected via Bluetooth can be determined based on the return value obtained by instantiating the BluetoothClass.Device class. If the returned value is AUDIO_VIDEO_CAMCORDER, it is characterized as an image capture device; if the returned value is AUDIO_VIDEO_CAR_AUDIO, it is characterized as a car device; if the returned value is AUDIO_VIDEO_HIFI_AUDIO, it is characterized as an audio playback device or a video playback device, such as a Bluetooth headset; If the returned value is AUDIO_VIDEO_MICROPHONE, it indicates that it is a microphone.

When it is determined that the electronic device is connected to the wireless audio playback device, that is, after the electronic device is connected to the wireless audio playback device, it is detected whether the electronic device has received a playback request, and the playback request is a request for playing audio data. When the electronic device is connected to the first wireless audio playback device and the first wireless audio playback device is selected as a device for playing audio data of the electronic device, it is determined whether a playback request for audio data of the data is obtained when the user operates the electronic device, and if Upon the playback request, it is determined that the electronic device is playing audio data through the first wireless audio playback device.

Specifically, the playback request may be reminder information or a voice playback request. The reminder information includes call reminder information, short message reminder information, and alarm reminder information to remind the user that certain events have been triggered. For example, the call reminder information is used to remind the user of an incoming call.

As another implementation manner, the utterance request may be a request to play a voice each time during the utterance of the electronic device. The utterance request may be an audio utterance request, or a video utterance request or a call utterance request.

Specifically, if multiple audio playback software is installed in the electronic device, the software may be a music playback APP, a video playback APP, a recording APP, or the like. For example, the video playback interface is provided with a video playback button. By detecting the touch of the video playback button, it can be determined whether the electronic device currently receives a playback request for audio data. For example, the user selects a video, enters the video playback interface, and clicks. The playback button of the playback interface allows the application to detect what type of video the user is currently clicking by monitoring the user ’s touch operation. Specifically, the playback button is set with preset attributes to detect the acquired touch By operating the properties of the corresponding playback button, the user can determine the video to be played selected by the user, and then obtain a playback request and the audio corresponding to the playback request.

Then, it is detected whether the electronic device obtains the switching instruction. Specifically, when the electronic device uses one wireless audio playback device to play audio data, the user can use another wireless audio playback device to play audio data. For example, the electronic device is using the first wireless audio playback device. When the wireless audio playback device plays audio data, it is detected whether the second wireless audio playback device is requested to play audio data, and if so, it is determined that a switching instruction is obtained.

As an implementation manner, the audio data of the electronic device may be switched in an interface of the electronic device. As shown in FIG. 4, when the user uses the first wireless audio playback device, the user selects the selected data in the interface. The first wireless audio playback device, and when the second wireless audio playback device is selected when switching, by detecting the selection button corresponding to the second wireless audio playback device, it can be determined whether the second wireless audio playback device is requested to play audio Data, if yes, it is determined that a switching instruction is obtained.

As another implementation manner, it is also possible to select which wireless audio playback device is used to play audio data in the audio playback interface of the electronic device. Specifically, as shown in FIG. 5, the wireless audio selected in the selection menu bar The playback device is used to play audio data, and the user switches from device 1 to device 2 and inputs a request to play audio data using the second wireless audio playback device, that is, a switching instruction is input.

S302: Keep the first wireless audio playback device to continue playing the audio data, and send the audio data to the second wireless audio playback device, and instruct the second wireless audio playback device to send the acquired audio data. storage.

After detecting the acquisition switching instruction, the first wireless audio playback device does not pause the audio data playback, that is, the user can still listen to the audio data in the first wireless audio playback device.

Perform audio decoding to obtain audio decoded audio data, and then store the audio decoded audio data into a preset storage space. Then, when the second audio playback device is playing, the decoded audio data can be obtained directly from the preset storage space and played directly, reducing the delay caused by the audio decoding process.

In some embodiments, the electronic device is currently connected to the first wireless audio playback device and the second wireless audio playback device at the same time, that is, when it is determined that the switching instruction is obtained, the electronic device is already connected to the second wireless audio playback device. When connected, the operations of maintaining the first wireless audio playback device to continue playing the audio data and sending the audio data to the second wireless audio playback device may be performed.

In other embodiments, if the electronic device is not connected to the second wireless audio playback device, it is necessary to first establish a connection, and then execute and keep the first wireless audio playback device to continue playing the audio data, and Operation of sending audio data to the second wireless audio playback device. Because a certain point of time is required in the process of establishing a connection, and audio data is being played, after the connection is established, the first wireless audio playback device is maintained to continue playing the audio data, and the The operation of sending audio data to the second wireless audio playback device can avoid the time required to establish the connection and increase the time delay added by the handover.

Specifically, the first wireless audio playback device is kept playing the audio data, and the audio data is sent to the second wireless audio playback device, and the second wireless audio playback device is instructed to send the acquired audio data. The specific implementation of data storage is:

Determine whether the electronic device and the second wireless audio playback device are connected, and if connected, keep the first wireless audio playback device to continue playing the audio data, and send the audio data to the first Two wireless audio playback devices, instructing the second wireless audio playback device to store the acquired audio data; if not connected, sending a connection playback instruction to the second wireless audio playback device to maintain the first wireless audio playback The device continues to play the audio data, and sends the audio data to the second wireless audio playback device, instructing the second wireless audio playback device to store the acquired audio data, wherein the connection playback instruction is used for And instructing the second wireless audio playback device to be connected to the electronic device. Specifically, when not connected, it may send a connection play instruction to the second wireless audio playback device, instructing the second wireless audio playback device to connect to the electronic device, and detecting whether a return from the second wireless audio playback device is received. Successful connection information, which is used to indicate that the second wireless audio playback device has successfully connected with the electronic device, and if the successful connection information is received, executing and maintaining the first wireless audio playback device to continue playing the audio data And sending the audio data to the second wireless audio playback device, instructing the second wireless audio playback device to store the acquired audio data.

S303: Acquire the playback progress of the audio data.

After the audio data is sent to the second wireless audio playback device, a playback progress of the audio data currently played by the electronic device is obtained.

As shown in FIG. 6, t1 is the current playback time point of the audio data, and then the current playback time point of the audio data is obtained as the playback progress of the audio data obtained this time. For example, if the total playback time of an audio data is 3:56, the current playback time point is 1:03, and 0 to 1:03 is the current playback progress.

As another implementation manner, a specific implementation manner of acquiring the playback progress of the audio data is: acquiring the current playback time point of the audio data, and using the current playback time point minus a preset value as the current time point. Playing progress of the acquired audio data. As shown in FIG. 7, t1 is the current playback time point of the audio data, and t2 is the playback time point before the current playback time point of the audio data. Then the time difference between t1 and t2 is Δt, and the time length of Δt is Set value. The preset value is a value set by the user according to requirements. For example, the value is 4-10 seconds, and specifically, it can be 6 seconds.

For example, a piece of speech is "I am from Sichuan, I love hot and sour noodles", the current playback time point is the time point corresponding to "Person", and the preset playback time point before the current playback time point is "I" Corresponding time point, the playback progress of the audio data obtained this time is not the time point corresponding to "person", but the time point corresponding to "me". Although the current time has been played to "person", it is switched to When the second audio playback device is used, it will rewind to "I" to start playback, so that when the user plays the voice using the second audio playback device, the user can recall the previously played content and improve the user experience.

S304: Send the playback progress to the second wireless audio playback device, and instruct the second wireless audio playback device to play the stored audio data according to the playback progress.

After the second wireless audio playback device obtains the playback progress, it locates a time point corresponding to the playback progress, and continues to play the audio data with the time point as a starting point. Therefore, before the second wireless audio playback device is instructed to play audio data, the audio data has been stored in the storage space in the second wireless audio playback device, to avoid delaying the acquisition of audio data from the electronic device when the playback is instructed to play. , And cause the phenomenon of stuttering.

In addition, when the electronic device sends the playback progress to the second wireless audio playback device, a reminder message is sent, and the reminder information is used to instruct the user to switch the audio playback device, for example, the above-mentioned "Please switch headphones" voice. At this time, the user gives up using the first wireless audio playback device to play audio data, and uses the second wireless audio playback device to seamlessly switch audio playback. Taking a Bluetooth headset as an example, when the electronic device sends the playback progress to the second wireless audio playback device, the first Bluetooth headset sends a reminder message of "Please switch the headset", and the user removes the first Bluetooth headset Or turn off, and then the second Bluetooth headset can continue to play following the playback progress of the first Bluetooth headset.

In addition, although in the operation of S302, when the first Bluetooth headset is kept playing the audio data, the user may not turn off the first Bluetooth headset when the first Bluetooth headset can hear sound. In order to prevent the user from taking off the first Bluetooth headset when switching, a warning voice may be played in the first wireless audio playback device when it is determined that a switching instruction is obtained, so as to remind the user to switch the wireless audio playback device later according to the prompt. .

Furthermore, after switching to the second wireless remote playback device to play audio data, the first wireless audio playback device may also be controlled to no longer output a sound corresponding to the audio data. Specifically, the specific implementation manner of controlling the first wireless audio playback device to no longer output the sound corresponding to the audio data may be:

As an implementation manner, the first wireless audio playback device may be muted. Specifically, the electronic device may send a sound suppression instruction to the first wireless audio playback device, so as to minimize the volume output by the first wireless audio playback device. Of course, it is also possible that the user clicks the mute button in FIG. 4 and enters a mute instruction, and the electronic device sends the mute instruction to the first wireless audio playback device to minimize the volume output by the first wireless audio playback device. The first wireless audio playback device is muted.

As another implementation manner, the first wireless audio playback device may be controlled to stop playing audio data, and specifically, a pause instruction is sent to the first wireless audio playback device, so that the first wireless audio playback device pauses playing audio data. It may be that, when the user operates the selection button corresponding to the first wireless audio device in the interface shown in FIG. 4, the selection button is switched to an unselected state, and the electronic device sends a pause instruction to the change when it detects the change. A first wireless audio playback device.

As another implementation manner, the first wireless audio playback device may also be turned off. Specifically, the electronic device sends a shutdown instruction to the first wireless audio playback device, so that the first wireless audio playback device is turned off.

Exemplarily, if the first wireless audio playback device and the second wireless audio playback device are both Bluetooth speakers, when the user inputs a switching instruction, the first wireless audio playback device continues to play audio data, and the user can continue to listen to the audio At the same time, the electronic device sends the audio data to the second wireless audio playback device for storage, and then obtains the playback progress of the audio data played by the first wireless audio playback device, and then controls the second wireless audio playback device to continue playing audio according to the playback progress. Data, it enables users to listen to audio data uninterruptedly and continuously.

As another example, if the first wireless audio playback device and the second wireless audio playback device are both Bluetooth headsets, when the user inputs a switching instruction, the first wireless audio playback device continues to play audio data, and the user can continue to pass the first The wireless audio playback device plays audio data, so the user will not take off, turn off or mute the first wireless audio playback device. Further, the above warning voice may be used to remind the user not to switch, and at the same time, the electronic device sends audio data Save to the second wireless audio playback device, and then obtain the playback progress of the audio data played by the first wireless audio playback device, and then control the second wireless audio playback device to continue playing audio data according to the playback progress, and then the user can save the first wireless audio The playback device is taken off, turned off, or muted, so that the user can also listen to the audio data uninterruptedly and continuously.

In addition, for a specific implementation manner of turning off the first wireless audio playback device, reference may be made to the steps shown in FIG. 8. Specifically, FIG. 8 illustrates an audio playback method provided by another embodiment of the present application, which is applied to the foregoing. The electronic device, specifically, the method includes: S801 to S806.
