Abstract
The utility model discloses a microphone. The microphone comprises a package structure which is formed in a manner that a shell and a circuit board are enclosed, wherein the package structure is provided with a sound hole which is used for receiving sound signals. Supporting members are arranged around the sound hole outside the package structure, and a flexible thin plate is fixedly arranged on the supporting members and covers above the sound hole. When airflow entering the interior of the microphone is greater, the flexible thin plate can locally or fully block the sound hole through the impact on the flexible thin plate by the airflow, so that the greater airflow is prevented from entering the interior of the microphone through the sound hole, and the components and devices inside the microphone are further prevented from being impacted by the greater airflow; and when the airflow is appropriate, the airflow can enter the interior of the microphone through gaps among the supporting members, so that the acoustical-electric conversion is realized, and the performance of the microphone is ensured.
Description
Technical field
The utility model relates to the acoustical-electrical transducer technical field, more particularly, relates to a kind of microphone.
Background technology
Along with the progress of society and the development of technology; In recent years; Along with electronic product volumes such as mobile phone, notebook computer constantly reduce; People are also increasingly high to the performance requirement of these portable electronic products, thereby also require the volume of supporting with it electronic component constantly to reduce, performance and consistency improve constantly.Under this background; A lot of novel products has also been released in microphone products field as one of strength member of above-mentioned portable electronic products; The microphone of which kind of form all has a sound hole that is used to receive voice signal; Outer gas stream gets into microphone inside through the sound hole, thereby affacts realization sound on the inner electronic devices and components of microphone-electricity conversion, but the microphone of this form can cause the inner electronic devices and components of microphone to suffer damage when the air-flow that gets into microphone inside is big; Simultaneously owing to the user at first removes with the air gun dust that microphone is inner in use; When removing dust, sustain damage, thereby influence performance of products, need design a kind of novel microphone thus owing to the air gun wind speed also possibly make the inner components and parts of microphone greatly.
The utility model content
In view of the above problems, the purpose of the utility model provides that a kind of can to prevent to get into the inner air-flow of microphone excessive and damage a kind of microphone of inner components and parts.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: a kind of microphone comprises by shell and wiring board and surrounds the encapsulating structure that forms that said encapsulating structure is provided with and receives voice signal is hole; Wherein, The outside said sound of said encapsulating structure is provided with strutting piece around the hole, is fixed with flexible thin on the said strutting piece, and said flexible thin covers top, said sound hole.
A kind of preferred version, said sound hole is arranged on the said wiring board, and the said strutting piece around the said sound hole is a pad, and the quantity of said pad is four.
A kind of preferred version, said flexible thin are FPCB, and said FPCB is provided with through pad and said wiring board fixed intervals.
A kind of preferred version, being shaped as of said shell and said wiring board is square.
A kind of preferred version, said microphone are the MEMS microphone.
Utilize above-mentioned microphone,, be fixed with flexible thin on the said strutting piece through around the outside said sound of said encapsulating structure hole, being provided with strutting piece according to the utility model; Said flexible thin covers top, said sound hole; When the air-flow that gets into microphone inside was big, through the impact of air-flow to flexible thin, flexible thin can or all be blocked part, sound hole; It is inner to prevent to get into microphone than air flow through the sound hole; Prevented that the inner components and parts of microphone from receiving the impact than air flow, when air-flow is suitable, can get into the inner realization sound of microphone-electricity conversion, guaranteed properties of product through the space between the strutting piece.
Description of drawings
Through with reference to below in conjunction with the explanation of accompanying drawing and the content of claims, and along with the more complete understanding to the utility model, other purpose of the utility model and result will understand more and reach easy to understand.
