Specific embodiment
Specific embodiment of the utility model is described in detail below with reference to accompanying drawing.
For foregoing, existing TypeC adapters cannot test earphone whether taken off from the earphone interface of TypeC adapters
Resistance value between the problem for falling, the voltage of sound channel contact that the utility model is arranged in earphone interface by detection and ground come
Determine whether earphone is inserted in the earphone interface of TypeC adapters, if earphone is not inserted into when in earphone interface, by controlling mould
Block control analog switch is closed, to block the audio signal that the terminal device being connected with TypeC interfaces sends.It is new by this practicality
Type can be detected to whether the earphone in the earphone interface for inserting TypeC adapters comes off, when earphone is from earphone interface
When coming off, the audio signal that blocking terminal device sends, so as to improve the experience of user.
To illustrate the headset transfer device based on TypeC that the utility model is provided, Fig. 1 is shown according to the utility model
The planar structure of the headset transfer device based on TypeC of embodiment；Fig. 2 show according to the utility model embodiment based on
The headset transfer device logical construction of TypeC.
