Embodiment 1

[0046] figure 2It is a cross-sectional view of a silicone diaphragm assembly structure provided in the embodiment of the present application. Wherein, the support ring 2 is a frame, which supports and positions the silicone diaphragm 1 . The silicone diaphragm 1 includes an edge portion 11, a surrounding ring 12 and a central portion 13, which are integrally structured without gaps between each other, and can completely avoid gaps between the edge portion 11 and the surrounding ring 12, and between the central portion 13 and the surrounding ring 12. Waterproof problem.

[0047] The edge portion 11 wraps the outer surface of the support ring 2, and is integrally attached to the outer surface of the support ring 2, so that there is no gap between the edge portion 11 and the support ring 2, and the waterproof performance between the edge portion 11 and the support ring 2 is enhanced. And it can save accessories such as sealing foam and rubber pads pasted on the front cover of ...

Embodiment 2

[0051] image 3 It is a cross-sectional view of a silicone diaphragm assembly structure provided in the embodiment of the present application. The support ring 2 is a frame, which supports and positions the silicone diaphragm 1 . At the same time, the support ring 2 replaces the front cover, which simplifies the product structure. The inner side of the support ring 2 is formed with a plurality of slopes, and the edge portion 11 is closely bonded to the multiple slopes with angles inside the support ring 2 , which is stronger than a single plane bonding, and the waterproof performance can also be improved.

[0052] The edge part of the middle sticker 4 is formed as a folded edge 41, and the folded edge 41 is bonded to the central part 13, thereby increasing the bonding area between the central part 13 and the middle sticker 4, and also increasing different bonding surfaces. Compared with the traditional process, only one plane of the middle sticker 4 is bonded, and the waterp...

Embodiment 3

[0055] Figure 4 A cross-sectional view of a silicone diaphragm assembly structure provided in an embodiment of the present application, Figure 5 is an exploded view of the silicone diaphragm assembly structure. The supporting ring 2 is a frame, and plays a role of positioning and supporting the silicone diaphragm 1 during assembly. The edge portion 11 is attached to the upper surface and the inner surface of the support ring 2, and the central portion 13 is bonded to the upper surface and part of the side edges of the middle sticker 4. On the surface, the waterproof performance and adhesion can be improved by increasing the vertical bonding surface or bonding surface.

[0056] The size of the support ring 2 can match the design size of the loudspeaker, or can be larger than the design size of the loudspeaker. When it is larger than the design size of the speaker, after the speaker assembly is completed, it can be cut along the Figure 4 Cut at the position indicated by t...

Abstract

The invention provides a silica gel diaphragm assembly structure for a loudspeaker, and a preparation method. The structure comprises a central paster; a silica gel diaphragm which generates a sound signal through vibration deformation; a supporting part which supports the silica gel diaphragm. The silica gel diaphragm further comprises an edge part which has a plurality of attaching surfaces with the supporting part; a central part which has a plurality of attaching surfaces with the central paster; and a folded ring which is integrated with the edge part and the central part. The structure is simple and compact in structure, can improve the waterproof performance of the silica gel diaphragm, and is convenient to take and locate.

Description

technical field [0001] The present application relates to the field of loudspeakers, in particular to a silicone diaphragm assembly structure and preparation method for loudspeakers. Background technique [0002] The loudspeaker is an electric-force-acoustic transducer, which is an important component in audio equipment. Loudspeakers are widely used in people's daily life and bring a lot of convenience. In the fields of electronic products such as automobiles, radios, TVs, speakers, mobile phones, MP4, computers, etc., the application of speakers can be seen almost everywhere. [0003] With the continuous improvement of people's requirements for waterproof and heat resistance of electro-acoustic devices such as speakers, speakers with silicone diaphragms and other electro-acoustic products have advantages in waterproof and thermal stability, and are being used more and more. [0004] figure 1 It is a schematic diagram of the bonding structure of the existing silicone diap...
