The utility model provides a microphone, small in noise, the pickup is effectual.
Description
Technical field
This utility model relates to electroacoustic apparatus technology, particularly relates to a kind of technology vibrating pickup microphone.
Background technology
Traditional mike is mainly made up of shell and installation microphone in the enclosure, shell offers pickup and leads to
Hole, external voice enters enclosure by pickup through hole, microphone passes to audio frequency apparatus after picking up.Tradition
When mike uses, microphone can pick up noise and normal sound simultaneously, due to the noise that comprises in original pickup relatively
Greatly, the effect of later stage noise reduction process is the most limited, when especially using in the environment of noise is relatively big, and substantially cannot be
Clear sound transfers out.In sum, it is big that conventional microphone also exists noise, the defect of pickup effect difference.
Utility model content
For defect present in above-mentioned prior art, technical problem to be solved in the utility model is to provide one
Noise is little, the vibration pickup microphone that pickup effect is good.
In order to solve above-mentioned technical problem, a kind of vibration pickup microphone provided by the utility model, its feature exists
In: include fixing seat, and be fixed on the fore shell on fixing seat, back cover, described fore shell is fixed with one there is elasticity
Vibrating diaphragm；
Described fore shell, vibrating diaphragm, fixing seat enclose a front pickup chamber, and described back cover, fixing seat enclose
Pickup chamber after one；
Offering a sound transmission aperture on described fixing seat, described front pickup chamber is connected with rear pickup chamber by sound transmission aperture, front
Pickup chamber, sound transmission aperture, the transaudient passage of rear pickup chamber one integrally closed of composition；
Described rear pickup intracavity is provided with a microphone, and the pickup end seal of this microphone covers the rear aperture of sound transmission aperture.
Further, the aperture of described sound transmission aperture is less than the internal diameter in front pickup chamber.
Further, described front pickup intracavity is provided with a vibration wave filter block, and this vibration wave filter block is fixed on vibration
The medial surface of diaphragm, vibration wave filter block is a metal derby.
Further, described vibration wave filter block is the one in copper billet, iron block, bloom, aluminium block, lead.
The vibration pickup microphone that this utility model provides, fixing seat, fore shell, back cover are empty with outside by transaudient passage
Air bound is opened, and can be prevented effectively from the interference to transaudient passage of the surrounding enviroment noise, and sound transmission aperture can ensure that vibration signal is accurate
True is transferred to microphone, and microphone can absorb the vibration signal leaking into rear pickup intracavity, has noise
Little, that pickup effect is good feature.
Accompanying drawing explanation
Fig. 1 is the structural representation of the vibration pickup microphone of this utility model embodiment.
Detailed description of the invention
Illustrate embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing, but the present embodiment is not
For limiting this utility model, every employing analog structure of the present utility model and similar change thereof, all should be listed this in
The protection domain of utility model, the pause mark in this utility model all represents the relation of sum.
As it is shown in figure 1, a kind of vibration pickup microphone that this utility model embodiment is provided, it is characterised in that:
Including fixing seat 1, and it is fixed on the fore shell 2 on fixing seat 1, back cover 3, described fore shell 2 is fixed with one and has
Elastic vibrating diaphragm 4；
Described fore shell 2, vibrating diaphragm 4, fixing seat 1 enclose a front pickup chamber 6, described back cover 3, fixing
Seat 1 enclose one after pickup chamber 7；
Offering a sound transmission aperture 8 on described fixing seat 1, described front pickup chamber 6 is by sound transmission aperture 8 and rear pickup chamber 7
Connection, front pickup chamber 6, sound transmission aperture 8, rear pickup chamber 7 constitute the transaudient passage of an integrally closed；
It is provided with a microphone 5, after the pickup end seal of this microphone 5 covers sound transmission aperture 8 in described rear pickup chamber 7
Aperture.
In this utility model embodiment, the aperture of described sound transmission aperture 8 is less than the internal diameter in front pickup chamber 6.
In this utility model embodiment, it is provided with a vibration wave filter block 9 in described front pickup chamber 6, this vibration wave mistake
Filter block 9 is fixed on the medial surface of vibrating diaphragm 4, and vibration wave filter block 9 uses copper billet, arranges vibration wave mistake
The purpose of filter block 9 is to filter out external environment condition (such as wind sometimes results in vibrating diaphragm to the interference of vibrating diaphragm 4
There is the slightest vibration) thus improve the pickup quality of mike, in this utility model other embodiments, vibration
Ripple filter block can also use iron block, bloom, aluminium block, lead etc., and other can realize identical function and (filters out outside
The environment interference to vibrating diaphragm) metal derby.
When this utility model embodiment uses, vibrating diaphragm 4 is attached to neck (comprising) any of the above position,
Vibrating diaphragm 4 is utilized to pick up the vibration signal that when people talks, head skeleton produces so that the air in front pickup chamber 6
Producing vibration, this air vibration arrives at microphone 5 by sound transmission aperture 8, microphone 5 be converted into the signal of telecommunication；
Fixing seat, fore shell, back cover can be prevented effectively from the interference to transaudient passage of the surrounding enviroment noise, and sound transmission aperture 8 can be protected
Barrier vibration signal is transferred to microphone 5 accurately, and microphone 5 can absorb and leak in rear pickup chamber 7
Vibration signal, can improve pickup effect.
