Abstract
Disclosed is an earphone system. The earphone system includes a charging box and an earphone, which is detachably assembled in the charging box. The charging box includes a processing module provided with a first identification time period, a power outputting module and a first switch module. During the first identification time period when the earphone is connected to the charging box, the earphone system is in a test mode, and the first switch module is switched for the charging box to transmit power to the earphone through the power outputting module and the first switch module. After the earphone is connected to the charging box for more than the first identification time period, the earphone system is in a communication mode, and the first switch module is switched for the charging box to transmit a data signal to the earphone through the processing module and the first switch module.
