Seen from the above description, the first thin slice, the second thin slice can adopt metal or other high-strength materials, it is to avoid vibrating diaphragm
When moving away from voice coil loudspeaker voice coil direction, depression occurs in barrier sheet causes air return.
Further, the vibrating diaphragm is adhesively fixed with the stiffening plate.
Seen from the above description, vibrating diaphragm is connected with stiffening plate simply, conveniently, is conducive to producing in enormous quantities；And work as vibrating diaphragm or
Stiffening plate can be individually replaced vibrating diaphragm or stiffening plate when damaging, and advantageously reduce use cost.
Embodiment one
Fig. 2 to Fig. 4 is refer to, embodiment of the present utility model is：Incorporated by reference to Fig. 2 and Fig. 3, a kind of speaker, including
The stiffening plate 3 of voice coil loudspeaker voice coil 1, the vibrating diaphragm 2, barrier sheet 4 and an annular of annular above voice coil loudspeaker voice coil 1,3 edge of the stiffening plate of annular
The vibrating diaphragm 2 it is circumferentially disposed, the barrier sheet 4 located at the stiffening plate 3 away from voice coil loudspeaker voice coil 1 one side and will annular described in
The hollow region of stiffening plate 3 is covered.
4 part of the barrier sheet is fixed on the stiffening plate 3, in the present embodiment, and barrier sheet 4 is passed through with stiffening plate 3
It is adhesively fixed.In other embodiments, barrier sheet and stiffening plate by way of fusion can carry out part and fix, and can pass through
Fastening structure carries out part and fixes, or even barrier sheet can be adopted with stiffening plate and is integrally formed.Further, the barrier sheet 4
Folding line is provided with, the barrier sheet 4 can turn down setting towards the direction away from voice coil loudspeaker voice coil 1 around the folding line, folding is set on barrier sheet 4
Trace, turns down can barrier sheet 4 more smooth.Used as optimization, the folding line is near barrier sheet 4 and the fixed area of stiffening plate 3
Arrange.
The barrier sheet 4 be with made by the material with certain elasticity, metal material and nonmetallic materials can, only
It is to need to realize turnover, such as copper than relatively thin, relatively thin metal barrier piece using the barrier sheet 4 that metal material is made
Paper tinsel, native silver etc.；Can have various using nonmetallic materials, for example rubber, plastics.
As shown in figure 4, in the present embodiment, the stiffening plate 3 is a rectangle frame, the side of 4 bottom surface of the barrier sheet with
The top surface of a line of the rectangle frame is adhesively fixed (bonding region 5, as shown in the figure).Further, the vibrating diaphragm 2 is hollow
Region is overlapped with the hollow region of the stiffening plate 3, so, is conducive to the circulation of inside loudspeakers air.
The vibrating diaphragm 2 is adhesively fixed with the stiffening plate 3.
This utility model speaker radiation processes are as follows：When voice coil loudspeaker voice coil 1 drive vibrating diaphragm 2 towards move away from 4 direction of barrier sheet when,
4 most of region of barrier sheet can be turned down along the folding line on barrier sheet 4, so that 2 top cavity of 2 lower cavity of vibrating diaphragm and vibrating diaphragm
Communicate, vibrating diaphragm 2 continues towards moving away from 4 direction of barrier sheet, force the air flow of 2 lower cavity of vibrating diaphragm empty to above vibrating diaphragm 2
Chamber；When voice coil loudspeaker voice coil 1 drives vibrating diaphragm 2 towards near the movement of 4 direction of barrier sheet, barrier sheet 4 is fitted with stiffening plate 3, is separated below vibrating diaphragm 2
2 top cavity of cavity and vibrating diaphragm, vibrating diaphragm 2 continue towards near the movement of 4 direction of barrier sheet, and barrier sheet 4 extrudes 2 top cavity of vibrating diaphragm
Air, forces the air that is squeezed to flow out from speaker voice giving hole.So, heat just with air from 2 lower cavity of vibrating diaphragm via
2 top cavity of vibrating diaphragm is discharged.
Embodiment two
Fig. 5 is refer to, embodiment of the present utility model two is the structure of barrier sheet to be made on the basis of embodiment one
Further improvement, the difference with embodiment one is：The barrier sheet 4 include the first thin slice 41, the second thin slice 42 with
And film 43；First thin slice 41 is adhesively fixed with the stiffening plate 3, and second thin slice 42 passes through the film 43 and the
One thin slice 41 connects.The effect of film 43 is similar to the effect of folding line in embodiment one, connects the first thin slice 41 and the second thin slice
42, and the first thin slice 41 is relatively rotated with the second thin slice 42.The film 43 can adopt polyester material, polyimides
The material with good bending performance such as material is made, simpler, and the film 43 can be exactly adhesive tape.
The so design of barrier sheet 4 is advantageous in that：The material that first thin slice 41, the second thin slice 42 can adopt intensity higher
Make, it is not necessary to which the material possesses certain elasticity, such as copper, ferrum, PVC etc., so as to avoid vibrating diaphragm 2 towards away from the shifting of 1 direction of voice coil loudspeaker voice coil
When dynamic, depression occurs in barrier sheet 4 causes the situation of air return to occur.
In sum, the speaker that this utility model is provided, by arranging a barrier sheet, is pushed away using the reciprocating motion of voice coil loudspeaker voice coil
The air of dynamic inside loudspeakers, forms heat exchange air-flow, greatly improves speaker heat-sinking capability；Barrier sheet takes up room and almost may be used
To ignore, so as to allow speaker to be more suitable for super-thin electronic equipment；Connect between barrier sheet and stiffening plate, between stiffening plate and vibrating diaphragm
Connect simple, convenient, be conducive to producing in enormous quantities；Durable in use, use cost is low.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalents made using this utility model description and accompanying drawing content, or directly or indirectly it is used in the technology neck of correlation
