It can be seen that themain headset 1 of the present application can also be used separately from theaccessory device 3, as a common wireless headset application that does not require a low latency scenario.

It can be seen that theslave earphone 2 of the present application can also be used separately from themaster earphone 1, as a common wireless earphone application that does not require a low latency scenario.

Further, themain headset 1 of the present application further includes afirst battery 17 and a first Power Management chip 18(PMIC (Power Management IC)); theslave earphone 2 further comprises asecond battery 24 and a secondpower management chip 25, and the working principle is as follows:

As an alternative embodiment, the process of playing audio based on two-channel audio data includes:
the timing is started when the two-channel audio data is transmitted to theslave earphone 2 through the NFMI communication, and when the timing time reaches the preset transmission waiting time, the audio playing is performed based on the two-channel audio data to synchronize the audio playing of the master earphone and the slave earphone.
Specifically, considering that it takes some time for themaster earphone 1 to transmit the binaural audio data to theslave earphone 2, if themaster earphone 1 performs audio playing based on the binaural audio data immediately after receiving the binaural audio data, the audio playing of themaster earphone 1 and theslave earphone 2 will be asynchronous, so the present application sets a transmission waiting time in advance (approximately equal to the time taken for themaster earphone 1 to transmit the binaural audio data to the slave earphone 2), themaster earphone 1 starts timing from transmitting the binaural audio data to theslave earphone 2 through NFMI communication, and performs audio playing based on the binaural audio data when the timing time reaches the preset transmission waiting time, thereby eliminating the time difference between the audio playing of themaster earphone 1 and theslave earphone 2, and synchronizing the audio playing of the master earphone and the slave earphones.
The application also provides an earphone system, which comprises the accessory device and the earphone.
It should be noted that the accessory device of the headset system can be plugged into the host device, and can also be integrated into the host device, for example, into the mobile phone, thereby implementing low-latency wireless headset application in cooperation with the mobile phone.
