COMMUNICATION CONTROL METHOD, DEVICE AND SYSTEM, CHARGING BOX AND WIRELESS EARPIECE

Disclosed by the present invention are a communication control method, device and system, a charging box and a wireless earpiece, the method comprising: when charging a first wireless earpiece by means of two power pins, the charging box obtains first data to be sent if communication with the first wireless earpiece is needed; and according to the first data to be sent, the charging box controls the output voltages of the two power pins to be correspondingly exchanged, so that the first wireless earpiece switches according to the output voltage of a corresponding power pin so as to obtain the first data to be sent during the charging process. In the present method, the charging box controls the output voltages of the two power pins to be correspondingly exchanged according to the first data to be sent, so that the wireless earpiece may obtain the first data to be sent according to the switching of the charging voltages when using the switchable charging voltages of the two power pins to perform charging. Therefore, the wireless earpiece uses the two pins used for charging to communicate with the charging box during the charging process, thereby reducing the setup cost and taking both a small size and aesthetic appearance into account.
