Abstract
The utility model discloses an electret capacitance-type microphone. The electret capacitance-type microphone comprises a parallel plate capacitor composed of a diaphragm, an isolating sheet and a pole plate, wherein the isolating sheet and the pole plate are designed as one integral entity. With the electret capacitance-type microphone of the utility adopted, the pole plate and the isolating sheet do not need to be assembled independently because that the isolating sheet and the pole plate are designed as the integral entity, thereby reducing operation steps and enabling simple technical process.
Description
Technical field
The utility model relates to a kind of acoustic-electric conversion equipment, relates in particular to a kind of electret capacitor microphone.
Background technology
Along with the progress of society and the development of technology, in recent years, along with the electronic product volumes such as mobile phone, notebook computer constantly reduce, people are also more and more higher to the performance requirement of these portable electronic products, thereby require also with it that the volume of supporting electronic component constantly reduces, performance and consistency improve constantly.Under this background, also released a lot of novel products as the microphone products field of one of strength member of above-mentioned portable electronic products, wherein take electret capacitor microphone as representative.The microphone of this kind structure comprises the plane-parallel capacitor that is comprised of diaphragm, spacer and pole plate, generally respectively separately design of diaphragm, spacer and pole plate, when assembling, install one by one according to a definite sequence respectively, operating procedure is comparatively loaded down with trivial details, technique is comparatively complicated, needs thus to design a kind of novel electret capacitor microphone.
The utility model content
In view of the above problems, the purpose of this utility model provides a kind of operating procedure that can reduce and makes the comparatively simple a kind of electret capacitor microphone of technique.
For addressing the above problem, the utility model by the following technical solutions: a kind of electret capacitor microphone comprises: the plane-parallel capacitor that is formed by diaphragm, spacer and pole plate, wherein, described spacer and described pole plate Integral design.
A kind of preferred technical scheme, the polar board surface relative with described diaphragm stretch out along the center and are provided with recessed groove, and the protuberance around the described recessed groove is described spacer.
A kind of preferred technical scheme, described spacer are to be coated with the insulating barrier that is located on the described pole plate.
Utilize above-mentionedly according to electret capacitor microphone of the present utility model, because with described spacer and described pole plate Integral design, do not need pole plate and spacer are installed separately when assembling, the operating procedure that has reduced assembling process makes technique comparatively simple.
Description of drawings
By the content of reference below in conjunction with the description of the drawings and claims, and along with understanding more comprehensively of the present utility model, other purpose of the present utility model and result will understand and easy to understand more.
Fig. 1 is the profile of the utility model embodiment electret capacitor microphone.
