Description

Microphone device

[technical field]

The utility model relates to electroacoustic switch technology field more particularly to a kind of microphone devices.

[background technique]

In recent years, Information technology is grown rapidly, and the popularity rate of audio frequency apparatus is higher and higher, requirement of the people to audio frequency apparatus It is not limited only to the broadcasting of video/audio, more requires to propose more requirements, especially 5G epoch to the reliability of audio frequency apparatus It arrives, Technology of Mobile Multimedia also develops therewith, and many audio frequency apparatuses have a variety of amusement functions, as video playing, number are taken the photograph Picture, game, GPS navigation etc., as functional requirement is more and more, in component integration degree it is higher and higher, to product Quality also require to be increasingly stringenter.

In audio frequency apparatus, microphone device is a kind of common electronic component, is mainly used for the broadcasting of audio signal, Structure design directly affects audio playback quality.The microphone device of the relevant technologies includes shell, Yi Jishou with receiving cavity It is dissolved in the intracorporal sounding monomer of the shell, sounding monomer is separated into corresponding ante-chamber and back cavity for cavity is accommodated, and shell is equipped with Through the acoustic aperture that goes out of its side wall, the sound that ante-chamber generates sounding monomer is exported from acoustic aperture is gone out.

In the microphone device of the relevant technologies, shell generallys use plastic casing, and plastic casing needs to have quite Thickness could effectively support sounding monomer, therefore usually steel disc is embedded in shell, to improve the intensity of shell, forms institute The housing plastic for stating out the steel disc edge of acoustic aperture will form a protrusion, to occupy part ante-chamber channel, influence the logical of air-flow Freely, acoustical behavior is reduced.

Therefore, a kind of new microphone device solution above-mentioned technical problem must be provided by having in fact.

[utility model content]

The purpose of this utility model is to provide one kind can guarantee that sounding channel is smooth, increases sounding channel height, changes The microphone device of kind acoustical behavior.

In order to achieve the above object, the utility model provides a kind of microphone device, including have receiving cavity shell, And be contained in the intracorporal sounding monomer of the shell, the sounding monomer by the receiving cavity be divided into corresponding ante-chamber with Back cavity, the microphone device further include the steel disc fixed with the shell gluing, and the edge of the steel disc includes and the shell The part of acoustic aperture and the remainder with the shell gluing are formed out, the acoustic aperture out is connected to the hair with the ante-chamber The sound that sound monomer generates is exported from the acoustic aperture out.

Preferably, the shell includes upper cover and surrounds the lower cover of the receiving cavity, the steel disc with the upper cover It is fixed with the upper cover gluing.

Preferably, the upper cover includes being recessed to be formed from its surface far from the lower cover to the direction close to the lower cover Sealing face, the steel disc fixes with the sealing face gluing.

Preferably, the steel disc is fixed with the sealing face by two-sided glue glued adhesion.

Compared with the relevant technologies, microphone device provided by the utility model eliminates the steel disc edge to form out acoustic aperture Shell can effectively increase the height in sounding channel to ensure that the smooth of sounding channel, improve acoustical behavior, even if When sounding monomer is amesiality, the opening of sounding monomer side can also be done greatly, the sounding monomer is effectively reduced and is biased to Influence of the air-flow to acoustics behind side.

[Detailed description of the invention]

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings, in which:

Fig. 1 is the perspective exploded view of microphone device provided by the utility model；
