Please refer to FIG. 1. FIG. 1 is a flowchart of an audio transmission method according to an embodiment of the present invention. As shown in FIG. 1, the audio transmission method includes the following steps:

Step 101: Decode audio files into a first channel audio signal and a second channel audio signal.

It is easy to understand that the audio file may be a song, audio in a video file, etc.; the audio file may be stored in the first electronic device, or may also be an audio file included in an application program of the first electronic device. In some other implementation manners, the audio file may also be referred to as a sound source file, sound source information, sound file, and so on.

In this step, the first electronic device may decode the audio file into a first channel audio signal and a second channel audio signal when the audio file is acquired. Optionally, the first channel audio signal may refer to a left channel audio signal, and the second channel audio signal may refer to a right channel audio signal. For example, the first electronic device may decode the acquired audio file, and decode the audio file into a left channel audio signal and a right channel audio signal. It should be noted that each sub-file in the audio file carries a left-channel audio source identifier or a right-channel audio source identifier, so as to facilitate the identification of the sub-file by the first electronic device to decode the audio file into Left channel audio signal and right channel audio signal. The specific decoding operation of the audio file by the first electronic device may refer to related technologies, which is not described in detail in this embodiment.

Step 102: Encode the first channel audio signal through the first wireless chip and send it to the first channel playback device of the second electronic device.

It should be noted that the second electronic device may refer to an audio playback device capable of receiving the audio file and playing the audio file, such as earphones and speakers.

In the embodiment of the present invention, after the first electronic device decodes the audio file into the first channel audio signal and the second channel audio signal, it may transmit the first channel audio signal to the first wireless chip and pass the first channel audio signal to the first wireless chip. A wireless chip encodes the first channel audio signal, and sends the encoded first channel audio signal to the first channel playback device of the second electronic device through the first wireless chip.

Step 103: Encode the second channel audio signal through a second wireless chip and send it to the second channel playback device of the second electronic device.

Understandably, the first electronic device encodes the second channel audio signal through the second wireless chip and sends it to the second channel playback device of the second electronic device, so that the audio file can be decoded into two parts and passed through the two parts. A wireless chip to send separately. In this way, compared with the existing audio files that can only be sent through a wireless chip, the solution provided by the embodiment of the present invention also doubles the audio transmission channel, which is more conducive to audio with a large amount of data. File transfer to ensure the transfer quality of audio files.

Optionally, the first wireless chip and the second wireless chip are both Bluetooth chips. In this way, on the basis of the existing Bluetooth technology and Bluetooth protocol, the first electronic device can decode the audio file into two parts by setting two Bluetooth chips, and encode and transmit the audio files separately through the two Bluetooth chips. The audio transmission channel in the first electronic device is doubled, and the transmission bandwidth is also doubled, so that the audio file does not need to be compressed, the sound quality of the audio file is not damaged, and the transmission quality of the audio file is guaranteed , To ensure the playback effect of audio files, and bring a better listening experience for users.

Optionally, in a specific embodiment, the first channel audio signal is a left channel audio signal, the second channel audio signal is a right channel audio signal, and the second electronic device is For audio playback equipment, the first channel playback device of the second electronic device is a left channel playback device, and the second channel playback device is a right channel playback device. For example, the first wireless chip is the first Bluetooth chip, the second wireless chip is the second Bluetooth chip, and the audio playback device is a Bluetooth headset, then the left channel playback device of the Bluetooth headset is the left headset, and the right channel playback device is the right headset . In this embodiment, the first electronic device can decode the audio file into a left-channel audio signal and a right-channel audio signal, and encode the left-channel audio signal through the first Bluetooth chip and send it to the left earphone of the Bluetooth earphone, The audio signal of the right channel is encoded by the second Bluetooth chip and then sent to the right earphone of the Bluetooth earphone.

It should be noted that the transmission bandwidth of Bluetooth is about 3 Mbps. In the case of only one Bluetooth chip, this limits the maximum transmission bandwidth that can be obtained for the left and right channel audio signals to 1.5 Mbps. In the solution provided by the embodiment of the present invention, the first electronic device can respectively send the left channel audio signal to the left earphone of the Bluetooth headset and the right channel audio signal to the right earphone of the Bluetooth headset through two independent Bluetooth chips, so that Both left and right channel audio signals can enjoy a transmission bandwidth of 3Mbps, which increases the transmission bandwidth of audio files, ensures the transmission quality of audio files, and avoids damage to the sound quality of audio files.

In addition, the first electronic device can send the left and right channel audio signals to the corresponding left and right earphones respectively according to the playback characteristics of the Bluetooth earphones. Compared with the existing Bluetooth earphones, the left and right earphones receive compressed together including left and right channel audio. The packaged file of the signal, the solution provided by the present invention also eliminates the need for the Bluetooth headset to decompress the audio file or extract the corresponding left and right channel audio signals after decompression, which simplifies the processing operation of the Bluetooth headset on the audio file.

It should be noted that the above is just taking the Bluetooth chip and the Bluetooth headset as an example of a specific implementation of the present invention as an illustration.

Optionally, since the first channel audio signal and the second channel audio signal are encoded and transmitted through the first wireless chip and the second wireless chip, respectively, the first wireless chip encodes and transmits the first channel audio signal. The transmission may be performed simultaneously with the encoding and transmission of the second channel audio signal by the second wireless chip, or may also be performed separately based on the working state of the second electronic device.

For example, in the case where the second electronic device is a headset, the left channel playback device is a left headset, and the right channel playback device is a right headset, the first electronic device may acquire the left headset and the right headset. The working state of the earphone, and then perform corresponding operations according to the working state of the left earphone and the right earphone. Specifically, the step 102 may include:

When the left earphone of the earphone is in use and the right earphone of the earphone is not in use, the left channel audio signal is encoded by the first wireless chip and then sent to the left earphone;

For example, when it is detected that the left earphone is in contact with the user's left ear and the right earphone is separated from the user's right ear, it means that the user is using or needs to use the left earphone at this time, and the first electronic device transmits the left channel audio signal through the first wireless chip. It is encoded and sent to the left earphone; when it is detected that the right earphone is in contact with the user’s right ear and the left earphone is separated from the user’s left ear, it means that the user is using or needs to use the right earphone at this time, and the first electronic device passes through the second wireless The chip encodes the right channel audio signal and sends it to the right earphone. In this way, the corresponding left and right channel audio signals can be sent according to the working state of the left and right earphones in the earphone. When the left earphone or the right earphone is not in use, the audio signal can not be sent to the left earphone or the right earphone, and then The use of unnecessary transmission bandwidth can be avoided, and the power consumption of the first electronic device can be reduced. Of course, if both the left earphone and the right earphone are in use, the first electronic device can send the encoded left channel audio signal to the left earphone through the first wireless chip, and at the same time send the encoded left channel audio signal to the right earphone through the second wireless chip. Right channel audio signal.
