Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Referring to Fig. 1, the utility model provides a kind of TYPE-C charging earphone, including TYPE-C plugs 1, earphone 2 and Charger 3, earphone 2 and TYPE-C plugs 1 are electrically connected with, and charger 3 includes power supply adaptor 31 and USB interface 32, TYPE-C Plug 1 is internally provided with control chip 11, and earphone 2 is electrically connected by DAC 4 with control chip 11, DAC 4 That is digital analog converter, analog signal is converted to for data signal, facilitates earphone 2 that signal is identified, power adaptation Device 31 is electrically connected by USB interface 32 with control chip 11, and power supply adaptor 31 can be to mobile terminal by control chip 11 Or electronic equipment is individually powered.

For the ease of the positive and negative grafting and power supply of TYPE-C charging earphones, further, DAC 4 and control chip CC interfaces on 11 are electrically connected with, and CC interfaces are used for collocation channel, and CC interfaces are the critical passages increased newly in USB Type-C, it Effect have detection USB connections, detect positive anti-plug, between USB device data and VBUS connection establish and manage etc..DAC is changed Device 4 is electrically connected with VCONN interfaces on control chip 11, and VCONN interfaces are used to give cable chip power supply.
