电子设备(例如智能手机、平板电脑等)，已经成为人们日常生活中最常用的消费型电子产品之一，随着无线通信技术的发展，用户在利用电子设备进行录音时，无线耳机因其方便携带等特点得到越来越广泛的应用。其中，真无线立体声(True Wireless Stereo，TWS)耳机由于其佩戴更为舒适、使用方便、不引人注目、更加小巧美观等优秀特性，TWS耳机在耳机市场的占有率逐渐提高。Electronic devices (such as smart phones, tablet computers, etc.) have become one of the most commonly used consumer electronics products in people's daily life. With the development of wireless communication technology, when users use electronic devices to record, wireless headphones are convenient. Features such as carrying are more and more widely used. Among them, True Wireless Stereo (TWS) earphones have gradually increased their share in the earphone market due to their excellent features such as more comfortable to wear, easier to use, unobtrusive, more compact and beautiful.
双耳立体声录音技术(Binaural Audio)是一种高度还原真实听感的录音技术，其通过在人工头部的两只耳朵位置配有麦克风，从而可以捕捉到达每只耳朵位置的声音，两个信号就可以分别在每只耳朵上重现。这种重现不适用单声道播放，如果用扬声器来播放也达不到预期的效果，所以通常会使用耳机，将两只耳朵接收的声信号完全隔离开，这种做法可以使人工头完全复刻听众所听到的内容。Binaural audio recording technology (Binaural Audio) is a recording technology that highly restores the real sense of hearing. It is equipped with microphones at the two ears of the artificial head, so that it can capture the sound reaching each ear. Two signals can be reproduced on each ear separately. This kind of reproduction is not suitable for monophonic playback, and if you use speakers to play it, it will not achieve the expected effect. Therefore, headphones are usually used to completely isolate the sound signals received by the two ears. This method can make the artificial head completely Replicate what the audience heard.
在实现双耳立体声录音时，可以使用TWS耳机的两个耳机分别设置的麦克风(Microphone，MIC)进行收音，可以达到以上双耳录音技术的效果。TWS耳机的两个耳机在采集音频数据后，需要通过蓝牙协议向手机蓝牙传输录制的双声道音频。由于需要保证录制的声场，录制音频的格式至少需要保证48khz(千赫兹)，16bit(比特)，2声道，此时压缩之后的带宽也至少需要400-500kbps(千比特每秒)，如果蓝牙的信号出现波动或者耳机距离手机较远时，传输的带宽就会变小，传输过程也容易出现卡顿或中断，从而导致录音出现卡顿或断续。When realizing binaural stereo recording, you can use the microphones (Microphone, MIC) set separately on the two earphones of the TWS earphone to collect sound, which can achieve the effect of the above binaural recording technology. After the two earphones of the TWS headset collect audio data, they need to transmit the recorded two-channel audio to the mobile phone Bluetooth through the Bluetooth protocol. Due to the need to ensure the recorded sound field, the format of the recorded audio must be at least 48khz (kilohertz), 16bit (bit), 2 channels. At this time, the bandwidth after compression also needs to be at least 400-500kbps (kilobits per second). If Bluetooth When the signal fluctuates or the earphone is far away from the mobile phone, the transmission bandwidth will become smaller, and the transmission process is also prone to stuttering or interruption, resulting in stuttering or intermittent recording.

在本申请实施例中，第一无线耳机获取的多种质量参数的每种质量参数可以对应的有一个预设参数条件，该预设参数条件用于确定该质量参数是否满足顺畅的传输音频数据至电子设备。第一无线耳机可以将每种质量参数与每种质量参数对应的预设参数条件进行匹配，然后确定出满足其对应的预设参数条件的质量参数的数量。可以理解地，满足预设参数条件的质量参数的数量越多，则表示第一无线耳机与电子设备之间无线通信的通信质量越好。In the embodiment of the present application, each quality parameter obtained by the first wireless earphone may correspond to a preset parameter condition, and the preset parameter condition is used to determine whether the quality parameter satisfies smooth transmission of audio data. to electronic equipment.

Understandably, the more quality parameters satisfying the preset parameter condition, the better the communication quality of the wireless communication between the first wireless earphone and the electronic device.
在一些实施方式中，预设参数条件可以为参数值条件。每种质量参数可以对应有多个参数值，例如，每种质量参数为预设时长内获取到的该类型的质量参数的多个参数值。第一无线耳机可以基于每种质量参数对应的多个参数值，获取每种质量参数对应的目标参数值；将每种质量参数对应的目标参数值与对应的参数值条件进行匹配，其中，每种质量参数对应一个参数值条件；获取多种质量参数中目标质量参数的数量，其中，目标质量参数的目标参数值与对应的参数值条件匹配。可选地，第一无线耳机基于每种质量参数对应的多个参数值，获取每种质量参数对应的目标参数值，可以是，获取每种质量参数对应的多个参数值的平均值，作为每种质量参数对应的目标参数值。In some implementations, the preset parameter condition may be a parameter value condition.

Since the greater the determined above quantity, it means that the communication quality between the first wireless earphone and the electronic device is better, so the coding bit rate can be positively correlated with the quantity, that is to say, the larger the quantity, the better the communication quality , so the encoding rate is higher.
在一些实施方式中，第一无线耳机中存储有编码码率与该数量之间的对应关系，第一无线耳机可以通过查找该对应关系，确定出与以上确定的数量所对应的编码码率，并将该编码码率作为目标码率。In some implementation manners, the first wireless earphone stores the correspondence between the encoding code rate and the quantity, and the first wireless earphone can determine the encoding code rate corresponding to the above-determined quantity by searching for the correspondence, And use the encoding bit rate as the target bit rate.

Among them, the encoding bit rate includes three ranges, 100~200kbps, 200~300kbps, and 300~400kbps; when starting to record, the initial compression bit rate is set to the highest, that is, under normal circumstances, the communication quality is better , at this time, a high bit rate is used for encoding, and the recorded sound quality is the best; in the subsequent recording process, the encoding can be determined according to the received signal strength and the number of parameters in the retransmission rate that meet the corresponding preset parameter conditions.

在本申请实施例中，第一无线耳机在获取到以上通信质量参数后，还可以将通信质量参数对应的参数值与第一阈值进行比较；根据比较结果，确定该参数值是否低于第一阈值；若低于第一阈值，表示第一无线耳机与电子设备之间的通信质量不佳，而通信质量不佳大多数情况下由于第一无线耳机与电子设备之间相距较远所致，因此，可以检测第一无线耳机相对电子设备的距离，以确定当前通信质量不佳是否由第一无线耳机与电子设备之间相距较远所致；若不低于第一阈值，则表示一无线耳机与电子设备之间的通信质量良好，因此可以不做处理。In the embodiment of the present application, after the first wireless earphone acquires the above communication quality parameters, it can also compare the parameter value corresponding to the communication quality parameter with the first threshold; and determine whether the parameter value is lower than the first threshold according to the comparison result. Threshold; if it is lower than the first threshold, it means that the communication quality between the first wireless earphone and the electronic device is not good, and the poor communication quality is mostly caused by the distance between the first wireless earphone and the electronic device, Therefore, the distance between the first wireless earphone and the electronic device can be detected to determine whether the current poor communication quality is caused by the distance between the first wireless earphone and the electronic device; if it is not lower than the first threshold, it indicates a wireless The communication quality between the headset and the electronic device is good, so it can be left alone.

When the obtained distance between the first wireless earphone and the electronic device is not less than the distance threshold, it means that the current communication quality of the wireless communication between the first wireless earphone and the electronic device is not good, not because of the distance between the first wireless earphone and the electronic device In this case, the current poor communication quality may be caused by the signal transmission being blocked due to the electronic device being in the pocket. Therefore, if the first wireless headset is worn, a prompt message can be output to prompt the user to place the electronic device Take it out from the pocket to improve the communication quality of the wireless communication between the first wireless earphone and the electronic device.
在一些实施方式中，由于增大无线通信的发射功率，会带来功耗的增加，因此，第一无线耳机在确定出其相对电子设备的距离小于距离阈值时，还可以获取第一无线耳机的剩余电量；若剩余电量大于电量阈值，表示当前剩余电量充足，因此增大第一无线耳机的无线通信的发射功率。若剩余电量小于或等于电量阈值，表示当前的剩余电量不充足，此时，可以获取第一无线耳机的佩戴状态；若第一无线耳机处于佩戴状态，输出目标提示信息，该目标提示信息用于提示用户减小第一无线耳机与电子设备之间的距离。In some implementations, increasing the transmission power of wireless communication will lead to an increase in power consumption. Therefore, when the first wireless headset determines that its distance from the electronic device is less than the distance threshold, the first wireless headset may also acquire the If the remaining power is greater than the power threshold, it means that the current remaining power is sufficient, so the transmission power of the wireless communication of the first wireless earphone is increased.
