Starting to play music, the first earphone receives the audio file of the mobile phone, converts it into a broadcasted electronic signal, and sends an electronic signal that should be output by the second earphone to the second earphone, so that the second earphone outputs music according to the electronic signal. While playing music, the mobile phone APP obtains the power status of the first earphone in real time. Specifically, the percentage of the remaining power of the first earphone is obtained, and the first remaining power value is generated; and then it is determined whether it is greater than the first threshold, that is, whether the remaining power is It is sufficient. If it is smaller than the first threshold, it is determined that it is necessary to switch between the main earphone and the slave earphone; then it is judged whether the current time is suitable for switching, and whether the audio player in the current mobile phone is playing an audio file, if not, Then the main earphone and the slave earphone are switched, which has less negative impact on the user experience and minimizes interference to the user's use. If it is determined that the audio player is playing an audio file, the APP temporarily does not switch between the main earphone and the slave earphone, and obtains the playing state of the audio player of the mobile phone in real time, and determines whether a command to switch or pause is received, and the command of switching or suspending makes The currently playing audio file stops. When the played audio file stops switching, the second earphone is switched to the main earphone, and the first earphone is switched to the slave earphone, so that the switching does not appear abrupt, and the music is switched after the music is stopped. To improve the user experience. The pause command is an instruction that the user actively sends a pause to play the music generation pause, or an instruction that the user switches to another program when the mobile phone is operated, and the playback of the audio file is forced to be suspended to generate a pause.
