Abstract
The utility model discloses a microphone including a packaging structure defined by a shell and a circuit board. The packaging structure is provided with a sound hole receiving sound signals. The periphery of the sound hole is provided with a dust shield on the external part of the packaging structure. A channel communicating the sound hole and the external is arranged in the surface of the dust shield corresponding to the sound hole or in the horizontal direction in the dust shield. Impacts of air flows entering into the microphone can be reduced through the channel, thereby preventing components in the microphone from damages. At the same time, a dustproof effect is realized. And the performance of the microphone is guaranteed without influencing a sound input effect.
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; Comprise by shell and wiring board and surround the encapsulating structure that forms that said encapsulating structure is provided with the sound hole that receives voice signal, wherein; The outside said sound of said encapsulating structure is provided with dust excluding plate around the hole, and said dust excluding plate surface or the dust excluding plate inner horizontal direction relative with said sound hole are provided with the passage that extraneous and said sound hole is communicated with.
A kind of preferred version, said sound hole is arranged on the said wiring board.
A kind of preferred version, said passage are arranged on the dust excluding plate surface relative with said wiring board.
A kind of preferred version, said microphone are the MEMS microphone.
Utilize above-mentioned microphone according to the utility model; Owing to around the outside said sound of said encapsulating structure hole, be provided with dust excluding plate, said dust excluding plate surface or the dust excluding plate inner horizontal direction relative with said sound hole are provided with the passage that extraneous and said sound hole is communicated with.Through the impact that this passage can reduce to get into the microphone internal gas flow, prevent that the inner components and parts of microphone from sustaining damage, play the dustproof effect simultaneously, guaranteed properties of product in the sound effective value not influencing into.
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.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the upward view of the utility model embodiment dust excluding plate.

Embodiment
Below will combine accompanying drawing that the specific embodiment of the utility model is described in detail.
Fig. 1 is the structural representation of the utility model embodiment; Fig. 2 is the upward view of the utility model embodiment dust excluding plate; Fig. 3 is the profile of the utility model embodiment microphone; To shown in Figure 3, a kind of microphone comprises by shell 1 and wiring board 2 and surrounds the encapsulating structure that forms like Fig. 1; The wiring board 2 of said encapsulating structure is provided with the sound hole 3 that receives voice signal; Wherein, be provided with dust excluding plate 4 around the outside said sound of the said encapsulating structure hole 3, be provided with the passage 41 that extraneous and said sound hole 3 is communicated with said sound hole 3 relative said dust excluding plate 4 surface level directions.
For the consistency that makes passage 41 well can be arranged on passage 41 on dust excluding plate 4 surfaces relative with said wiring board 2 through etching method; Through the impact that this passage 41 can reduce to get into the microphone internal gas flow, prevent that the inner components and parts of microphone from sustaining damage.
Microphone in the present embodiment is the MEMS microphone, can certainly be the microphone of other structure.
Utilize above-mentioned microphone according to the utility model; Owing to around the outside said sound of said encapsulating structure hole, be provided with dust excluding plate; Be provided with the passage that extraneous and said sound hole is communicated with the relative said dust excluding plate surface level direction in said sound hole,, prevent that the inner components and parts of microphone from sustaining damage through the impact that this passage can reduce to get into the microphone internal gas flow; Play the dustproof effect simultaneously, guaranteed properties of product in the sound effective value not influencing into.
More than show and described the basic principle and the principal character of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; Strutting piece in the utility model is a pad, also can be other fixture in the reality, under the prerequisite that does not break away from the utility model spirit and scope; The utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
