Problems solved by technology
However, in fact, the charging box of this design only has the function of charging, and does not have the function of communicating with the earphones
[0004] However, if three or more thimbles are used, not only does the structure look extremely complicated, but it is not simple and beautiful enough, and it will also lead to a decrease in user experience.

The embodiment of the invention discloses a charging box, a wireless earphone and a wireless earphone charging system, the charging box comprises a chip system, a first switch, a second switch, a first electrode, a second electrode and a charging port, the chip system comprises a UART and an MCU, the MCU is connected with the UART, and a signal receiving port of the UART is connected with a firstselection end of the first switch. A signal sending port of the UART is connected with a second selection end of the first switch; the common end of the first switch is connected with the first selection end of the second switch, the charging port is connected with the second selection end of the second switch, the common end of the second switch is connected with the first electrode, and the second electrode is grounded; and the MCU is used for controlling the first switch to switch between a data receiving function and a data sending function and controlling the second switch to switch between a data communication mode and a charging mode. By adopting the charging box, the charging box is simple in structure and convenient in function switching.
Description
technical field [0001] The present application relates to the field of electronic technology, and in particular to a charging box, a wireless earphone and a wireless earphone charging system. Background technique [0002] With the popularity of wireless earphones, people have higher and higher requirements for wireless earphones and charging boxes for charging the wireless earphones. Not only the charging box is required to charge the wireless earphones, but also the two are required to communicate. In order to make the appearance of the charging box simple and beautiful, and save resources, the structural design of double thimbles is mostly used in the market now. [0003] In the structural design of the double thimble, the two thimbles are positive and negative respectively. This structure determines that the communication mode between the charging box and the earphone is a single line, and the charging line and communication line must be shared. However, in fact, the ch...
