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 audio.

In this embodiment of the present invention, both the first wireless audio playback device 210 and the second wireless audio playback device 220 may be Bluetooth speakers or Bluetooth headsets, and the first wireless audio playback device 210 and the second wireless audio playback device 220 can be enabled by enabling the Bluetooth function The connection with the electronic device 100 is realized, and after the connection is established, the electronic device 100 sends the voice to be played to the Bluetooth speaker, and the Bluetooth speaker realizes the 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 simultaneously connect to the first wireless audio playback device 210 and the second wireless audio playback device 220 through the Bluetooth module, as a In this embodiment, the Bluetooth module in the electronic device can support multi-point connection, so that the electronic device shown in FIG. After the connection, the electronic device 100 can obtain the identifiers of the first wireless audio playback device 210 and the second wireless audio playback device 220, and the identifiers may be MAC addresses. Specifically, when the Bluetooth function of the electronic device is turned on, the electronic device will scan the Bluetooth devices within a certain distance. For example, scan the common channels 1, 7, and 13 first, and then scan other uncommon channels, thereby obtaining the identifiers of all Bluetooth devices within the current range and displaying them in the Bluetooth list interface of the electronic device. .

If there is a bluetooth device that has been connected and has good signal strength in the scanned bluetooth device identifier, 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.

Specifically, the electronic device can simultaneously connect two wireless audio playback devices through the True Wireless Stereo (TWS) protocol. For example, a Bluetooth speaker and a mobile phone are used as an example. The mobile phone is connected to the main speaker, and then the main speaker is connected to the main speaker through Bluetooth wireless Connect from the speaker to achieve true Bluetooth left and right channel wireless separation.

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 be implemented to play different audio data, and of course, different audio playback devices can also be played.

Specifically, the electronic device sends a protocol inquiry instruction to the wireless audio playback device, and the protocol inquiry instruction includes the identifier of the target transmission protocol. After arriving at the protocol inquiry instruction, parse the protocol inquiry instruction to obtain the identifier of the target transmission protocol, and search for the identifiers of all protocols supported by the wireless audio playback device. identities of all protocols. It is determined whether the identifier of the target transmission protocol is included in the identifiers of all supported protocols. If so, it is determined that the wireless audio playback device supports the target transmission protocol. If not, it is determined that the wireless audio playback device does not support the target transmission protocol.

As another implementation manner, the electronic device may also send a protocol query instruction to the wireless audio playback device, instructing the wireless audio playback device to return the identifiers of all supported protocols based on the protocol query instruction. The electronic device acquires the identifiers of all protocols supported by the wireless audio playback device, and the electronic device determines whether the acquired identifiers of all protocols supported by the wireless audio playback device include the identifier of the target transmission protocol, if included, then determine The wireless audio playback device supports the target transmission protocol. If it is not included, it is determined that the wireless audio playback device does not support the target transmission protocol.

The type of audio playback device, after acquiring the device information, determine the supported protocol corresponding to the device information of the wireless audio playback device according to the corresponding relationship of the protocols supported by the preset device information, so as to determine the corresponding protocol of the device information. Whether the supported protocol includes the target transmission protocol, if so, it is determined that the wireless audio playback device supports the target transmission protocol, if not, it is determined that the wireless audio playback device does not support the target transmission protocol.

S3012: Obtain the query result returned by the wireless audio playback device.

Wherein, the inquiry result is the information returned based on the protocol inquiry instruction, specifically, it may be the result of whether the returned wireless audio playback device determines whether it supports the target transmission protocol, or it may be the supported data returned by the wireless audio playback device. The identifiers of all protocols can also be the device information of the wireless audio playback device.

S3013: Based on the query result, determine whether the wireless audio playback device to be connected supports the target transmission protocol.

Based on different query results, it is determined whether the wireless audio playback device to be connected supports the target transmission protocol in different ways. As an embodiment, the above-mentioned wireless audio playback device obtains that the protocol query request sent by the electronic device includes the identifier of the target transmission protocol, and then determines whether the identifier of the target transmission protocol is included in the identifiers of all supported protocols. , will return the first information and if not included, will return the second information, where the first information and the second information can be two different values, for example, the first information is 1, the second information is 0, then When the electronic device obtains the first information and the second information, it can determine whether the result corresponding to the first information or the second information indicates whether the wireless audio playback device supports the target transmission protocol according to the pre-agreed rule. For example, if the first information is 1, 1 indicates that the wireless audio playback device supports the target transmission protocol, and 0 indicates that the wireless audio playback device does not support the target transmission protocol.

As another implementation manner, the query result is the identifiers of all protocols supported by the wireless audio playback device returned by the wireless audio playback device. As another implementation manner, the query result is the wireless audio playback device returned by the wireless audio playback device. If the device information is determined, based on the query result, to determine whether the wireless audio playback device to be connected supports the target transmission protocol, reference may be made to the foregoing description.

S302: Send an update instruction to the wireless audio playback device, instructing the wireless audio playback device to update the supported transmission protocol and be able to support the target transmission protocol.

If the wireless audio playback device supports the target transmission protocol, execute S303, and if the wireless audio playback device does not support the target transmission protocol, send an update instruction to the wireless audio playback device.

As an embodiment, the update instruction is instruction information, which is used to instruct the wireless audio playback device to download a data packet corresponding to the target transmission protocol on the data server, and the installation of the data packet enables the wireless audio playback device to support the target transmission protocol. Wherein, if the target transmission protocol has been sent to the wireless audio playback device when the electronic device sends the protocol inquiry command to the wireless audio playback device, then when the update command is sent, the target transmission protocol can be updated by the update command. The identifier is sent to the wireless audio playback device, instructing the wireless audio playback device to download the data packet corresponding to the target transmission protocol in the data server, wherein the data server can be the server corresponding to the wireless audio playback device, and the data server stores the corresponding data of the wireless audio playback device. Some of the data used to upgrade the system or the Bluetooth transmission protocol, the wireless audio playback device can access the data server through the specified domain name address, and obtain data packets corresponding to the required target transmission protocol in the data server.

In addition, if the electronic device does not send the target transmission protocol to the wireless audio playback device when the electronic device sends the protocol inquiry command to the wireless audio playback device, then when sending the update command, the identifier of the target transmission protocol is sent to the wireless audio playback device. device, instructing the wireless audio playback device to download the data packet corresponding to the target transmission protocol in the data server.

Specifically, the electronic device can also send the version number of the target transmission protocol supported by itself to the wireless audio playback device, and the wireless audio playback device downloads the data package corresponding to the version number in the data server according to the version number, so that the wireless audio playback device downloads the data package corresponding to the version number in the data server. The audio playback device is updated to enable the wireless audio playback device to support the target transport protocol.

As another implementation, it is not necessary for the wireless audio playback device to download the data packet corresponding to the target transmission protocol in the data server, and the electronic device directly sends the data packet to the wireless audio playback device. Specifically, the update instruction is sent to The wireless audio playback device instructs the wireless audio playback device to update the supported transmission protocol so as to be able to support the target transmission protocol. The specific implementation is: sending an update packet to the wireless audio playback device, instructing the The wireless audio playback device updates the supported transmission protocol according to the update data packet, so as to be able to support the target transmission protocol. Specifically, the content of the sent update data packet is the data packet of the target transmission protocol, and the data packet of the target transmission protocol is used for the wireless audio playback device to update the supported Bluetooth transmission protocol so as to be able to support the target transmission protocol. Then the above update request includes the update data package.

Specifically, after determining that the wireless audio playback device does not support the target transmission protocol, the electronic device determines whether a data packet of the target transmission protocol is stored in the electronic device, and if a data packet of the target transmission protocol is stored, sends an update data packet to the The wireless audio playback device instructs the wireless audio playback device to update the supported transmission protocol according to the update data packet, so as to be able to support the target transmission protocol, wherein the update data packet is a data packet of the target transmission protocol. If the data packet of the target transmission protocol is not stored, send instruction information to the wireless audio playback device, instructing the wireless audio playback device to download the data packet corresponding to the target transmission protocol to update the Bluetooth of the wireless audio playback device transport protocol, so that the target transport protocol can be supported.

Furthermore, it can also be determined according to the channel quality of the channel between the electronic device and the wireless audio playback device which method is used to update the Bluetooth transmission protocol of the wireless audio playback device. Specifically, when the electronic device determines that the wireless audio playback device does not support the target transmission After the agreement, obtain the channel quality of the channel between the electronic device and the wireless audio playback device, if the channel quality meets the preset conditions, send an update packet to the wireless audio playback device, instructing the wireless audio playback device according to the The update data packet updates the supported transmission protocol so as to be able to support the target transmission protocol, wherein the update data packet is the data packet of the target transmission protocol, and if the preset conditions are not met, send instruction information to the wireless audio player device, instructing the wireless audio playback device to download the data packet corresponding to the target transmission protocol, so as to update the Bluetooth transmission protocol of the wireless audio playback device, so as to be able to support the target transmission protocol.

The channel quality may be the error vector magnitude of the channel, the number of access points, the signal strength, and the like. Among them, Error Vector Magnitude (EVM for short) refers to the vector difference between the ideal error-free reference signal and the actual transmitted signal at a given moment, which is used to measure the amplitude error and phase error of the modulated signal. EVM specifically represents the signal received by the receiving terminal. The closeness of the IQ component generated during demodulation to the ideal signal component is an index to consider the quality of the modulated signal. The smaller the EVM, the better the channel quality of the channel. The number of access points can also be obtained by acquiring the access points on each channel during channel scanning, so that the number of access points on each channel can be determined. The worse the channel quality, and vice versa, the better. Similarly, the signal strength can also be obtained during channel scanning. The higher the signal strength, the higher the channel quality, and vice versa.

Then the channel quality satisfies the preset condition, which may be that the EVM value of the channel is less than the preset value. The preset value may be set by the user according to actual needs. Since the smaller the EVM value is, the higher the channel quality will be. If the EVM value is smaller than the preset value, it can indicate that the channel quality of the current channel is ideal, and an update data packet is sent. When it reaches the wireless audio playback device, the transmission will not be too slow due to poor channel. If the EVM is greater than or equal to the preset value, it means that the channel quality of the current channel is poor. The wireless audio playback device can communicate with the data server. The link between them downloads the data packets corresponding to the target transport protocol.

S303: Connect with the wireless audio playback device based on the target transmission protocol.

Then after sending an update instruction to the wireless audio playback device to instruct the wireless audio playback device to update the supported transmission protocol, the electronic device sends a connection request to the wireless audio playback device, and the connection request includes the name of the target transmission protocol, Then the wireless audio playback device and the electronic device transmit data based on the target transmission protocol.

Then considering that it takes a certain time for the wireless audio playback device to update the supported Bluetooth transmission protocol, if, after sending the update instruction to the wireless audio playback device, it is connected to the wireless audio playback device based on the target transmission protocol, then It is possible that the wireless audio playback device has not been updated, and the target transmission protocol is still not supported. At this time, a connection is established, and the electronic device and the wireless audio playback device still cannot establish a connection through the target transmission protocol.

Therefore, as an implementation manner, the specific implementation of the connection with the wireless audio playback device based on the target transmission protocol may be: judging whether to receive the successfully updated information fed back by the wireless audio playback device; if received, then connect with the wireless audio playback device based on the target transmission protocol.

Specifically, when the wireless audio playback device successfully updates the Bluetooth transmission protocol and can support the target transmission protocol, it will feed back an update success message to the electronic device, where the update success message can be a text message or a parameter value, the electronic device By parsing the text information or the parameter value, the device can determine that the wireless audio playback device has successfully updated the Bluetooth transmission protocol and can support the target transmission protocol. In addition, the update success information may also be a connection establishment request fed back by the wireless audio playback device when the Bluetooth transmission protocol has been successfully updated and can support the target transmission protocol. The protocol is connected with the wireless audio playback device.

As another implementation manner, after the electronic device sends the update instruction to the wireless audio playback device, it delays for a certain period of time and then connects with the wireless audio playback device based on the target transmission protocol. Specifically, please refer to FIG. 6 example shown.

FIG. 6 shows a device connection method provided by another embodiment of the present application, which is applied to the above electronic device. Specifically, the method includes: S601 to S605.

S601: Detect whether the wireless audio playback device to be connected supports the target transmission protocol.

S602: Send an update instruction to the wireless audio playback device, instructing the wireless audio playback device to update the supported transmission protocol and be able to support the target transmission protocol.

Wherein, if the wireless audio playback device supports the target transmission protocol, then perform S605, if the wireless audio playback device does not support the target transmission protocol, then perform S603, in addition, considering that if the audio data to be played is urgent, then S603 may not be performed, Instead, choose to use another transport protocol to establish the connection.

Specifically, it is determined that the audio data that the electronic device currently wants to play through the wireless audio playback device is used as the target audio data. Specifically, it may be that the electronic device is currently playing audio data, but the audio data is not played through the wireless audio playback device, but It is to play audio data through other playback devices, such as speakers of electronic devices or wired headphones. At this time, the user stops using the other playback devices, establishes a connection between the electronic device and the wireless audio playback device, and continues to play the audio data through the wireless audio playback device. audio data.

The electronic device determines the real-time level of the target audio data, and if the real-time level of the target audio data is higher than a preset level, connects with the wireless audio playback device based on a preset transmission protocol. The preset transmission protocol is the transmission protocol used when the electronic device was once connected to the wireless audio playback device. Specifically, it may be that the electronic device is provided with a connection record between the electronic device and the wireless audio playback device, and the connection record records the electronic device. The time point of each connection between the device and the wireless audio playback device and the transmission protocol used, then one of the transmission protocols in the connection record is used as the default transmission protocol. The transport protocol is used as the default transport protocol. In addition, the preset transmission protocol may also be a basic transmission protocol, for example, may be a basic transmission protocol supported by all devices supporting Bluetooth connection.

Audio data has a real-time level, and some data have high real-time requirements, for example, audio data in voice chat or video chat, or voice during a call, or audio played synchronously with video. However, some data have low real-time requirements, such as playing songs, etc., that is, pure songs instead of videos.

As an implementation manner, the identifier of the application program corresponding to the audio data is determined, and then the real-time level of the audio data is determined according to the identifier of the application program. Specifically, the identifier of the target application that sends the playback request of the audio data is determined, and then the type of the application corresponding to the identifier of the target application is determined.

After the identifier of the target application is acquired, the type of the target application is determined according to the identifier, where the identifier of the target application may be the package name, name, etc. of the application. For example, the identification of the application program and the corresponding relationship with the category of the application program are pre-stored in the electronic device, as shown in Table 1 below:

Table 1

Application ID category of application Apk1 game Apk2 video Apk3 audio

In this way, according to the corresponding relationship between the identifier of the application program and the category of the application program shown in Table 1, the category of the application program corresponding to the target application program can be determined. For example, in the embodiment of the present application, the game screen of the game software of the electronic device is played through the wireless audio playback device, and the game screen includes images and music, and the music may be game music, game sound effects, etc. For example, the game sound effects may be Gunshots or footsteps. As an example, the audio data may be game sound effects, the application program corresponding to the game sound effects is a certain game APP, and the category to which it belongs is a game type, and then the type of the audio data is determined according to the type of the application program. The type of the application can be used as the type of the audio data. For example, if the type of the application is a game, the type of the audio data is also a game.

Then, the real-time level corresponding to the audio data is determined according to the type of the application. Specifically, the real-time level corresponding to the type of application stored in the electronic device is shown in Table 2 below:

Table 2

Application ID category of application real-time level Apk1 game J1 Apk2 video J2 Apk3 audio J3 Apk4 social contact J1

Thus, the real-time level corresponding to the audio data can be determined. In addition, if it is determined that the category of the application program corresponding to the audio data is audio, the application program that can play audio may also play video, and it is necessary to determine whether the audio data is audio in the video.

Specifically, in some embodiments, it is determined whether a video is currently being played. Specifically, when the electronic device is playing a video, it will extract the audio data in the video and send it to the audio processing module in the system to call the electronic device. The audio processing circuit sends the audio data to the audio processing circuit for audio encoding and other operations. Therefore, after receiving the playback request of the audio data, it determines whether the video is currently being played. If so, it means that the audio to be played currently belongs to The audio data in the video currently being played, that is, the audio data belongs to the audio in the video.

In some other embodiments, the process of the electronic device playing the video is: after data de-protocol and de-encapsulation, it is divided into audio decoding and video decoding, the decoded audio data is sent to the audio playback device for playback, and the video data is sent to Video playback device playback. Therefore, in order to facilitate the simultaneous playback of video and audio, the audio and video frames in the video will be set with similar identifiers. For example, both audio and video frames use the A+B identifier format, where A is the preamble, which is used for Indicates that it belongs to a certain video, then when the audio data to be played is acquired, it can be determined whether the audio corresponds to a video frame, that is, whether it belongs to the audio in the video, according to the format of the identification of the audio data.

However, if it is determined that the category of the application corresponding to the audio data is the audio category, it is then determined whether the audio data is audio in the video, and if so, it is determined that the real-time level of the audio data is changed to the real-time level corresponding to the video-type application. level, rather than the real-time level corresponding to audio applications.

After acquiring the real-time level of the target audio data, it is determined whether the real-time level is higher than a preset level. It is judged whether the real-time level of the audio data belongs to a level greater than a preset level. The preset level is a preset real-time level corresponding to the type of audio playback delay that needs to be reduced, and may be set by the user according to requirements. For example, the preset level is J2 and above. Then, if the real-time level corresponding to the audio data is J1, the real-time level of the audio data is greater than the preset level; otherwise, it is determined to be less than or equal to the preset level. If it is greater than the preset level, connect to the wireless audio playback device based on the preset transmission protocol, thereby giving up executing this method.

S603: Starting from an update time point, time a preset time length, where the update time point is the time point at which the update instruction is sent.

Among them, the preset time length can be set by the user according to the needs. Generally, a long time value can be set, but the user's feeling must be taken into consideration, and the time cannot be too long. If the preset time length is set, the preset time length is less than or equal to the desired time.

In addition, considering that if the channel quality of the channel between the electronic device and the wireless audio playback device is too poor, the time required for the electronic device to send to the wireless audio playback device is longer, and the preset needs to be determined according to the channel quality. length of time. Specifically, for the acquisition method of the channel quality of the channel between the electronic device and the wireless audio playback device, reference may be made to the foregoing embodiments, and details are not described herein again. After the channel quality is obtained, the preset time length is determined according to the channel quality.
