Having some examples, as shown in Figure 8, rough surface can also be arranged to lobe 2011 and protrude from folding
The surface at ring portion 2 place, the portion concave of depression is in the surface at place, described ring portion 2.This side
Formula adhesion zone has bigger specific surface area.
Process for convenience, improve yields and specific surface area is controlled, at a kind of tool of the present utility model
In the embodiment of body, vibrating diaphragm uses the mode being molded one-body molded.During injection, first, according to setting
The specific surface area that fixed structure and wanting reaches manufactures mould, and mould is pre-in the position corresponding with adhesion zone
First make roughening to process；Then, the raw material of vibrating diaphragm, such as plastics, silica gel etc. are molded into mould
In, to be solidified after the i.e. available vibrating diaphragm with adhesion zone.
It is connected with the fixing of ring portion 2 for the ease of lead-in wire 301, concrete in one of the present utility model
Embodiment in, as shown in Figure 3-4, adhesion zone is arranged on the surface of the close coil in ring portion 2.
Such as, ring portion 2 protrudes near the side of coil, and for the ease of installing, adhesion zone is arranged on
On the surface of the outside being positioned at ring portion 2.Such as, in water proof type loudspeaker monomer, ring portion 2
Protruding to the side away from coil, for the ease of installing, adhesion zone is arranged on the inside in ring portion 2
On surface.
For the ease of processing and ensure to go between 301 adhesive strength, concrete in one of the present utility model
Embodiment in, as shown in Figure 1-2, adhesion zone is arranged to rectangle, the long limit of adhesion zone put down
Row is in the bearing of trend of lead-in wire 301, and the length of the broadside of adhesion zone is more than or equal to the diameter of lead-in wire 301.
The pliable of vibrating diaphragm can be improved in rectangular adhesion zone.Certainly, the shape of adhesion zone can be but not office
It is limited to circle, parallelogram, as long as being provided that enough adhesive strengths.
It is understood that the area of adhesion zone is the biggest, then the area taking ring portion 2 is the biggest, right
The vibrating effect in ring portion 2 produces the biggest adverse effect.The area of adhesion zone is the least, then go between 301
Bond area the least, lead-in wire is 301 the most insecure.So should select according to actual needs suitably
Bond area.
In order to ensure to go between 301 adhesive strength, and ensure that vibrating diaphragm has good vibrating effect, as
Shown in Fig. 1-2, one of the present utility model preferred embodiment in, vibrating diaphragm is rectangular ring,
The length on the long limit of adhesion zone is less than or equal to the 1/4 of the length of side on limit, place, adhesion zone.
