Backboard is arranged at intervals and is located at side of the backboard away from the vibrating diaphragm, orthographic projection of each support column on the backboard
In the different acoustic aperture, one end of the support column is fixedly connected with the vibrating diaphragm, and the other end is consolidated with the position-limited rack
Fixed connection.
It is preferred that, each support column is located in the adjacent acoustic aperture along projection of the direction of vibration on the backboard.
It is preferred that, the position-limited rack is parallel with the backboard and spaced flat board.
It is preferred that, the position-limited rack includes parallel with the backboard and spaced main part and each support column
The fixed part and the connecting portion of the connection main part and the fixed part for corresponding and being connected with each support column.
It is preferred that, each fixed part and the connected connecting portion along direction of vibration on the backboard just
Projection is located in the same acoustic aperture.
It is preferred that, the microphone sets multiple protection structures.
It is preferred that, the quantity of the backboard is two, and backboard described in two is respectively arranged on the two opposite sides of the vibrating diaphragm.
It is preferred that, the both sides of the vibrating diaphragm are equipped with the protection structure.
Compared with correlation technique, the beneficial effect for the microphone that the utility model is provided is：
By being arranged at intervals the position-limited rack in side of the backboard away from the vibrating diaphragm, and the position-limited rack passes through institute
Support column is stated to be fixedly connected with the vibrating diaphragm, so as to realize the vibrating diaphragm twocouese it is spacing, and then wheat can be lifted
Gram wind reliability.
【Brief description of the drawings】
The part-structure schematic diagram of one preferred embodiment of the microphone that Fig. 1 provides for the utility model；
Fig. 2 is sectional view of the microphone along A-A directions shown in Fig. 1.
【Embodiment】
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1 and Fig. 2 are referred to, the microphone 100 includes capacitor system, and the capacitor system includes being provided with multiple acoustic aperture
It is 11 backboard 1, relative with the backboard 1 and be arranged at intervals to form the vibrating diaphragm 3 of electric capacity and vibrate for the vibrating diaphragm 3 spacing
Protection structure 5.The vibrating diaphragm 3 vibrates after receiving sound wave.
In the present embodiment, the quantity of the backboard 1 is one；Accordingly, the quantity of the protection structure 5 can be one
It is individual, or multiple.It is appreciated that in other embodiments, the quantity of the backboard 1 can be two, and described in two
Backboard 1 is respectively arranged on the two opposite sides of the vibrating diaphragm 3；The quantity of the protection structure 5 can be the two-phase located at the vibrating diaphragm 3
Two of offside, or multiple.
The protection structure 5 includes position-limited rack 51 and supports at least two support columns 53 of the position-limited rack 51, the limit
Position frame 51 is arranged at intervals with the backboard 1 and positioned at side of the backboard 1 away from the vibrating diaphragm 3, each edge of support column 53
Orthographic projection of the direction of vibration on the backboard 1 be located at the different acoustic aperture 11 in, one end of the support column 53 with it is described
Vibrating diaphragm 3 is fixedly connected, and the other end is fixedly connected with the position-limited rack 51.In the present embodiment, the quantity of the support column 53 is
Two, and along direction of vibration, projecting on the backboard 1 is located in the adjacent acoustic aperture 11 two support columns 53.
In other embodiments, a position-limited rack 51 can also connect multiple support columns 53, described to strengthen
The intensity of protection structure 5.
The position-limited rack 51 includes parallel with the backboard 1 and spaced main part 511 and each support column 53
