Embodiment
To be fully understood by the purpose of this utility model, feature and effect, hereby by following specific embodiments, and coordinate attached
Figure, elaborates the utility model, illustrates as after：
Please refer to Fig.2 to Fig. 4, wherein Fig. 4 and do not show vibrating diaphragm, as shown in the figure, the utility model provides a kind of diaphragm structure,
It includes vibrating diaphragm 21, intermediate plate 22 and voice coil loudspeaker voice coil 23.
Vibrating diaphragm 21 has outstanding side 211.
22 top surface of intermediate plate is incorporated into the bottom surface of vibrating diaphragm 21, and strengthening portion 221 is equipped with intermediate plate 22, strengthening portion 221
Rigidity is more than the rigidity of vibrating diaphragm 21.
Voice coil loudspeaker voice coil 23 is incorporated into the bottom surface of intermediate plate 22 and the outer peripheral edge of neighbouring intermediate plate 22, and the outer peripheral edge of intermediate plate 22 is located at
Outside the outer peripheral edge of voice coil loudspeaker voice coil 23, and voice coil loudspeaker voice coil 23 is located at the outstanding lower section of side 211.
In the preferred embodiment of the utility model, the outer rim on outstanding side 211 can have outward flange 212, hang side 211
Inner edge can have central part 213, and central part 213 can be flat film, and intermediate plate 22 can be plane plate, the top of intermediate plate 22
Face is incorporated into the bottom surface of central part 213, and the outer peripheral edge of intermediate plate 22 is located at the outstanding lower section of side 211.
In addition, the strengthening portion 221 of intermediate plate 22 can include multiple carved pattern bodies 2211 (or multiple concave, convex point-like
Body, not shown), and intermediate plate 22 can be for made by macromolecule membrane, plastics, wooden or metal material.
When the utility model is when using, the stent 24 that can arrange in pairs or groups, magnetic return component 25 and U-shaped bottom seat 26, slim so as to forming
Loudspeaker 2；Wherein U-shaped bottom seat 26 is arranged on 24 bottom of stent, and magnetic returns component 25 and is arranged on U-shaped bottom seat 26, and magnetic is returned outside component 25 and lived
It is dynamic to be arranged with voice coil loudspeaker voice coil 23, and bottom surface of the top surface of intermediate plate 22 then with the central part 213 of vibrating diaphragm 21 is combined, when intermediate plate 22 is with shaking
When film 21 combines, there can be the one side for waiting carved pattern body 2211 to set upward with strengthening portion 221 intermediate plate 22, and make intermediary
The outer peripheral edge of plate 22 is located at the outstanding lower section of side 211, and the outward flange 212 of vibrating diaphragm 21 is incorporated into stent 24, and makes the top of voice coil loudspeaker voice coil 23
