Document Type and Number:
WIPO Patent Application WO/2019/196056
Kind Code:
A1
Abstract:
The present application provides an earphone control apparatus and a wired earphone. The earphone control apparatus comprises: a countercurrent detection control circuit; the microphone end of the earphone is connected to an energy storage circuit of the earphone by means of the countercurrent detection control circuit; the countercurrent detection control circuit is used for comparing a voltage in the energy storage circuit with a voltage of the microphone end of the earphone, and according to the comparison result, electrically connecting or electrically disconnecting the energy storage circuit and the microphone end. In the embodiments of the present invention, if the voltage of the energy storage circuit is higher than the voltage of the microphone end of the earphone, then the control apparatus effectively prevents the charge in the energy storage circuit from being lost to the power supply end of the terminal device, thus reducing the waste of electric charge and further avoiding sudden loss of power of the earphone as a result of a loss of charge in the energy storage circuit.
