步骤101、解码音频文件为第一声道音频信号和第二声道音频信号。 Step 101, decode an audio file into a first channel audio signal and a second channel audio signal.

容易理解地，所述音频文件可以是歌曲、视频文件中的音频等；所述音频文件可以是存储于第一电子设备中，或者也可以是第一电子设备的应用程序中包含的音频文件。在其他的一些实施方式中，所述音频文件也可以被称之为音源文件、音源信息、声音文件等。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 contained in an application program of the first electronic device. In some other implementation manners, the audio files may also be called audio source files, audio source information, sound files, and so on.

本步骤中，第一电子设备可以是在获取到音频文件的情况下，将所述音频文件解码为第一声道音频信号和第二声道音频信号。可选地，所述第一声道音频信号可以是指左声道音频信号，所述第二声道音频信号可以是指右声道音频信号。例如，第一电子设备可以是对获取的音频文件进行解码，将所述音频文件解码为左声道音频信号和右声道音频信号。要说明的是，所述音频文件中的每一个子文件都携带有左声道音源标识或是右声道音源标识，进而以方便第一电子设备对子文件的识别，以将音频文件解码为左声道音频信号和右声道音频信号。所述第一电子设备对音频文件的具体解码操作可以是参考相关技术，本实施例对此不做赘述。In this step, the first electronic device may decode the audio file into a first channel audio signal and a second channel audio signal if 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 that the first electronic device can easily identify the sub-file and decode the audio file into A left channel audio signal and a right channel audio signal. For the specific decoding operation of the audio file by the first electronic device, reference may be made to related technologies, which will not be described in detail in this embodiment.

步骤102、通过第一无线芯片对所述第一声道音频信号进行编码后发送给第二电子设备的第一声道播放装置。Step 102: Encode the audio signal of the first channel through the first wireless chip and send it to the first channel playing device of the second electronic device.

需要说明的是，所述第二电子设备可以是指能够接收所述音频文件，并对所述音频文件进行播放的音频播放设备，如耳机、音响等。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, stereos, and the like.

本发明实施例中，第一电子设备在将音频文件解码为第一声道音频信号和第二声道音频信号后，可以是将第一声道音频信号传输给第一无线芯片，并通过第一无线芯片对第一声道音频信号进行编码，并通过第一无线芯片将编码后的第一声道音频信号发送给第二电子设备的第一声道播放装置。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 playing device of the second electronic device through the first wireless chip.

步骤103、通过第二无线芯片对所述第二声道音频信号进行编码后发送给所述第二电子设备的第二声道播放装置。Step 103: Encode the audio signal of the second channel through the second wireless chip and send it to the second channel playing device of the second electronic device.

可以理解地，第一电子设备通过第二无线芯片对第二声道音频信号进行编码后发送给第二电子设备的第二声道播放装置，进而使得音频文件可以解码为两部分，并通过两个无线芯片来分别发送。这样，相比于现有的音频文件只能通过一个无线芯片来进行发送，本发明实施例提供的方案，也就将音频的传输通道扩展了一倍，也就更有利于数据量大的音频文件的传输，确保音频文件的传输质量。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 the Each wireless chip is sent separately. In this way, compared to the existing audio files that can only be sent through a wireless chip, the solution provided by the embodiment of the present invention doubles the audio transmission channel, which is more conducive to audio files with a large amount of data. The transmission of files ensures the transmission quality of audio files.

可选地，所述第一无线芯片和第二无线芯片均为蓝牙芯片。这样，在现有的蓝牙技术和蓝牙协议的基础上，第一电子设备通过设置两个蓝牙芯片，将音频文件能够解码为两部分，分别通过两个蓝牙芯片分别进行编码和传送，这样也就将第一电子设备中音频的传输通道扩展了一倍，传输带宽也提升了一倍，进而可以不用对音频文件进行压缩操作，不会造成音频文件的音质受损，保证了音频文件的传输质量，确保了音频文件的播放效果，为用户带来更好的听觉体验。Optionally, both the first wireless chip and the second wireless chip are 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 file respectively 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 can not be compressed, and the sound quality of the audio file will not be damaged, ensuring the transmission quality of the audio file , ensuring the playback effect of the audio file and bringing a better listening experience to the user.

可选地，在一种具体的实施方式中，所述第一声道音频信号为左声道音频信号，所述第二声道音频信号为右声道音频信号，所述第二电子设备为音频播放设备，所述第二电子设备的第一声道播放装置为左声道播放装置，第二声道播放装置为右声道播放装置。例如，第一无线芯片为第一蓝牙芯片，第二无线芯片为第二蓝牙芯片，音频播放设备为蓝牙耳机，那么蓝牙耳机的左声道播放装置为左耳机，右声道播放装置为右耳机。本实施方式中，第一电子设备能够将音频文件解码为左声道音频信号和右声道音频信号，并通过第一蓝牙芯片对左声道音频信号进行编码后发送给蓝牙耳机的左耳机，通过第二蓝牙芯片对右声道音频信号进行编码后发送给蓝牙耳机的右耳机。Optionally, in a specific implementation manner, 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 In the audio playback device, 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 earphone, then the left channel playback device of the bluetooth earphone is the left earphone, and the right channel playback device is the right earphone . 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 right channel audio signal is encoded by the second bluetooth chip and sent to the right earphone of the bluetooth earphone.

需要说明的是，蓝牙的传输带宽大约为3Mbps，在只有一个蓝牙芯片的情况下，这就限定了左右声道音频信号所能获得的传输带宽最大为1.5Mbps。而本发明实施例提供的方案，第一电子设备能够通过两个独立的蓝牙芯片，分别向蓝牙耳机的左耳机发送左声道音频信号，向蓝牙耳机的右耳机发送右声道音频信号，使得左右声道音频信号都能享受3Mbps的传输带宽，这样也就提升了音频文件的传输带宽，保证了音频文件的传输质量，避免音频文件音质受损。It should be noted that the transmission bandwidth of Bluetooth is about 3Mbps. In the case of only one Bluetooth chip, this limits the transmission bandwidth of the left and right channel audio signals to a maximum of 1.5Mbps. In the solution provided by the embodiment of the present invention, the first electronic device can send the left channel audio signal to the left earphone of the Bluetooth earphone and the right channel audio signal to the right earphone of the Bluetooth earphone 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.

另外，第一电子设备能够根据蓝牙耳机的播放特征，将左右声道音频信号分别发送至对应的左右耳机，相比于现有蓝牙耳机的左右耳机接收的是压缩在一起的包括左右声道音频信号的打包文件，本发明提供的方案也就使得蓝牙耳机无需对音频文件进行解压操作，也无需在解压之后再提取对应的左右声道音频信号，简化了蓝牙耳机对音频文件的处理操作。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. Signal packaging files, the solution provided by the present invention also makes it unnecessary for the Bluetooth headset to decompress the audio file, and does not need to extract the corresponding left and right channel audio signals after decompression, which simplifies the processing operation of the Bluetooth headset on the audio file.

需要说明的是，以上只是以蓝牙芯片、蓝牙耳机为例作为本发明的一种具体实施方式作为说明，本发明中的第一无线芯片、第二无线芯片以及音频播放设备还可以是其他的实施方式，例如第一无线芯片及第二无线芯片还可以是无线保真(Wireless-Fidelity，WIFI)芯片，或者是超宽带(Ultra Wide Band，UWB)芯片等；所述第二电子设备还可以是无线音响，如蓝牙音响等。It should be noted that the above is just an example of a bluetooth chip and a bluetooth earphone as a specific embodiment of the present invention as an illustration, and the first wireless chip, the second wireless chip and the audio playback device in the present invention can also be other implementations For example, the first wireless chip and the second wireless chip can also be a wireless fidelity (Wireless-Fidelity, WIFI) chip, or an ultra-wideband (Ultra Wide Band, UWB) chip, etc.; the second electronic device can also be Wireless speakers, such as Bluetooth speakers, etc.

可选地，由于第一声道音频信号和第二声道音频信号分别是通过第一无线芯片和第二无线芯片进行编码和发送，那么第一无线芯片对第一声道音频信号的编码和发送，可以是与第二无线芯片对第二声道音频信号的编码和发送同时进行，或者也可以是基于第二电子设备的工作状态分别进行。Optionally, since the audio signal of the first channel and the audio signal of the second channel are encoded and sent through the first wireless chip and the second wireless chip respectively, the first wireless chip encodes and transmits the audio signal of the first channel The sending may be performed simultaneously with the encoding and sending of the second channel audio signal by the second wireless chip, or may be performed separately based on the working state of the second electronic device.

例如，在所述第二电子设备为耳机，所述左声道播放装置为左耳机，所述右声道播放装置为右耳机的情况下，所述第一电子设备可以是获取左耳机和右耳机的工作状态，再根据左耳机和右耳机的工作状态来执行相应的操作。具体地，所述步骤102可以包括：For example, in the case where the second electronic device is an earphone, the left-channel playing device is a left earphone, and the right-channel playing device is a right earphone, the first electronic device may obtain the left earphone and the right earphone. The working status of the earphone, and then perform corresponding operations according to the working status of the left earphone and the right earphone. Specifically, the step 102 may include:

在所述耳机的左耳机处于使用状态且所述耳机的右耳机处于未使用状态的情况下，通过所述第一无线芯片对所述左声道音频信号进行编码后发送给所述左耳机；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;

所述步骤103包括：The step 103 includes:

在所述耳机的右耳机处于使用状态且所述耳机的左耳机处于未使用状态的情况下，通过所述第二无线芯片对所述右声道音频信号进行编码后发送给所述右耳机。When the right earphone of the earphone is in use and the left earphone of the earphone is not in use, the right channel audio signal is encoded by the second wireless chip and sent to the right earphone.

可选地，左耳机及右耳机可以是分别设置有启动开关，若启动开关开启，则对应的左耳机或右耳机处于使用状态，若启动开关未开启，则对应的左耳机或右耳机处于未使用状态。第一电子设备可以是通过耳机发送的信号来获知耳机的工作状态。或者，耳机的左耳机和右耳机可以是分别安装有红外传感器，通过红外传感器来检测左耳机或右耳机是否与用户的左耳或右耳接触，以确定左耳机及右耳机是处于使用状态还是处于非使用状态。Optionally, the left earphone and the right earphone can be respectively provided with start switches, if the start switch is turned on, then the corresponding left earphone or right earphone is in use state, if the start switch is not turned on, then the corresponding left earphone or right earphone is in the off state. status of use. The first electronic device may learn the working state of the earphone through a signal sent by the earphone. Or, the left earphone and the right earphone of the earphone can be equipped with infrared sensors respectively, and detect whether the left earphone or the right earphone is in contact with the user's left ear or right ear through the infrared sensor, so as to determine whether the left earphone and the right earphone are in use or not. is not in use.

例如，当检测到左耳机与用户的左耳接触且右耳机脱离用户右耳时，则说明用户此时正在或者需要使用左耳机，则第一电子设备通过第一无线芯片对左声道音频信号进行编码后发送给所述左耳机；当检测到右耳机与用户的右耳接触且左耳机脱离用户左耳时，说明用户此时正在或者需要使用右耳机，则第一电子设备通过第二无线芯片对右声道音频信号进行编码后发送给所述右耳机。这样，也就能够根据对耳机中左右耳机的工作状态，来发送对应的左右声道音频信号，在左耳机或右耳机处于未使用状态时，可以不向左耳机或右耳机发送音频信号，进而能够避免使用不必要的传输带宽，降低第一电子设备的使用功耗。当然，若左耳机和右耳机都处于使用状态，则第一电子设备能够通过第一无线芯片向左耳机发送编码后的左声道音频信号，同时通过第二无线芯片向右耳机发送编码后的右声道音频信号。For example, when it is detected that the left earphone is in contact with the user's left ear and the right earphone is out of 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. After encoding, send it 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 out of the user's left ear, it means that the user is using or needs to use the right earphone at this time, then the first electronic device passes the second wireless The chip encodes the right channel audio signal and sends it to the right earphone. In this way, it is also possible to send the corresponding left and right channel audio signals according to the working status of the left and right earphones in the earphone. 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 audio signal to the right earphone through the second wireless chip. Right channel audio signal.

In this way, the audio transmission channel in the first electronic device is also doubled, and the transmission bandwidth is also doubled, thereby improving the transmission quality of audio files, ensuring the playback effect of audio files, and bringing users better auditory experience.
