Abstract

The invention discloses a TypeC earphone switching cable and wired headset typec connection system and belongs to the technical field of an earphone interface circuit. The typeC earphone switching cable comprises a cable body, a TypeC plug and an earphone socket. The TypeC plug is set at one end of the cable body. The earphone socket is set at the other end of the cable body. According to the technical scheme provided by the invention, the TypeC connection of the wired earphone is realized through the TypeC earphone switching cable, so an earphone MIC and a GND analog handover switch do not need to be additionally added to a mobile terminal, and the cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of earphone interface circuits, in particular to a Type C earphone conversion cable and a wired earphone Type C connection system. Background technique [0002] With the gradual popularization of TYPE C sockets, many mobile terminals on the market have begun to cancel the traditional headphone sockets, and use Type C sockets to connect Type C headphones to realize the wired connection of headphones. However, since the TYPE C socket supports forward and reverse insertion, in order to adapt to the insertion of Type C earphones, it is necessary to add an analog switch between the earphone MIC (microphone) and GND in the mobile terminal, which is costly. However, single-type earphones are generally used on mobile terminals, such as American standard earphones or European standard earphones. In the existing technical solutions, even if single-type earphones are used, it is still necessary to add an analog switch ...
