Earphone and wireless communication system

Abstract

The application relates to the technical field of wireless earphones, in particular to an earphone and a wireless communication system. The earphone comprises an antenna module and a first circuit board. The antenna module at least comprises a first radiator for transmitting a first wireless signal and a second radiator for transmitting a second wireless signal, so that the earphone can perform wireless communication in at least two frequency bands, thereby improving the wireless communication capability of the earphone. The first circuit board at least comprises a first transceiver and a first circuit for transmitting a first electric signal and a second transceiver and a second circuit for transmitting a second electric signal. The first antenna is connected with the first circuit through a first switch to make the first antenna transmit the first wireless signal. The second antenna is connected with the second circuit through a second switch to make the second antenna transmit the second wireless signal. The wireless communication mode of the earphone can be adjusted through the first switch and the second switch, and the wireless communication performance of the earphone can be further improved.
