Description

Skin contact piezoelectric microphone

The utility model relates to a kind of microphone, particularly a kind of skin contact piezoelectric microphone.

General known skin contact microphone, it is to be installed with a source of sound receiver on an end of a hoop body, this source of sound receiver is to be connected with an end of a signal line, this signal line end in addition then is provided with a plug, to be plugged on the sound source follower by this plug, so, can this microphone can be fixed on the sound source part by this hoop body, make this source of sound receiver can be attached to contiguous this sound source part place, when this sound source part is sounded the generation sound wave, can convert this sound wave to a signal by this source of sound receiver and import this signal line, by this signal line this signal is reached this sound source follower again, to convert this signal to voice output by this sound source follower.

But, this microphone there is no and closely is attached on this sound source part, the sound wave that source of sound produces that this sound source part is sent can't reach on this source of sound receiver fully, even this sound source follower can't be exported the sound that sends near this sound source part, and make this source of sound confused, be difficult for making the people to listen and distinguish this sound.

In addition, a kind of Handless that is used on the mobile phone, it is that a end in one first signal line is provided with an earphone, end in one second signal line is provided with microphone, the end in addition of this two signal line is to connect to establish a plug, this plug is to be plugged on the jack of mobile phone, make and by this first signal line the signal that mobile phone sends to be reached earphone, to convert this signal to voice output by this earphone, and the sound that the user sends can convert signal to by microphone, by this second signal line this signal is exported on the mobile phone again.

But, can be except that the sound that the user sends by this microphone, outside second signal line exports on the mobile phone, outside sound also can be passed through this microphone, second signal line exports on the mobile phone, make the listener and except that hearing the sound that the user sends, also can hear the sound that the external world is imported into, make and talked about quality variation, and can't know the sound of hearing that the user sends, especially as user during at steering vehicle, the extraneous sound of the wind that noise and steering vehicle produced or the sound of sound equipment very easily import this microphone into, make the more difficult clear sound that the user sends of hearing of listener.

In view of this, for improving used shortcoming, the creator is through the permanent research and experiment of making great efforts, and development and Design goes out a kind of skin contact piezoelectric microphone of the present utility model finally.

The purpose of this utility model provides a kind ofly sends sound clearly, and does not have the skin contact piezoelectric microphone of other noises.

Above-mentioned purpose of the present utility model is realized by following technical scheme.
