WIRELESS EARBUD, CHARGING BOX, AND CHARGING SYSTEM FOR WIRELESS EARBUD

摘要

Disclosed are a wireless earbud, a charging box, and a charging system for a wireless earbud. The wireless earbud comprises: a charging port configured to connect to a charge voltage of the earbud, and receive/transmit a communication signal; a communication switching circuit comprising a first input/output end and a second input/output end, wherein the first input/output end is connected to the charging port; when connecting to the charge voltage of the earbud at the charging port, the communication switching circuit is switched to an off state, and when connecting to the communication signal at the charging port, the communication switching circuit is switched to an on state; a communication switch circuit connected to a second input/output end of the communication switch circuit; and an earbud control circuit configured to perform in-box detection on the wireless earbud and generate a corresponding detection signal to control the communication switching circuit according to the detection signal to turn on/off the electrical connection between the earbud control circuit and the communication switch circuit. According to the present invention, the functioning of charging and communication is achieved by the charging port, which can reduce contacts between the wireless earbud and the charging box.
