preparation example Construction
[0041] Such as figure 2 As shown, the preparation method of the diaphragm comprises the following steps:
[0042] S1: Coating the first material to form a film and cross-linking and curing, or extruding the first material to form a porous film.
[0043] The first material is fiber, silicone, acrylic, rubber, polyethylene naphthalate, polyethylene terephthalate, polybutylene terephthalate, One of polyurethane, polyetheretherketone, polytetrafluoroethylene, polyvinylidene fluoride, polyimide, polyetherimide, and polyphenylene sulfide.
[0044] The first material is coated into a film, and a curing agent is added to cause a cross-linking reaction. The cross-linking reaction refers to the formation of two or more molecules (usually linear molecules) that are bonded and cross-linked to form a network structure. Reaction of more stable molecules (body molecules). This reaction transforms linear or slightly branched macromolecules into a three-dimensional network structure, there...
Embodiment 1
[0059] Such as image 3 As shown, the material 1 in the figure is made of synthetic fiber, and the material 2 is made of silica gel. Firstly, the synthetic fiber is made into a fiber cloth, and then the silica gel is coated on the surface of the synthetic fiber membrane, and the silica gel is infiltrated into the pores of the synthetic fiber, so that the pores of the fiber are filled with silica gel, and the synthetic fiber and silica gel interpenetrate each other. A diaphragm with a very good network interpenetrating structure is prepared.
[0060] The vibrating membrane is used as a vibrating membrane part of a sound generator, and can effectively improve the sound quality and fidelity effect of the generating device.
Embodiment 2
[0062] Such as image 3 As shown, material 1 in the figure can also be made of natural fiber cloth, and material 2 is made of natural rubber. First, the natural fiber is made into a natural fiber cloth, and then the natural rubber is coated on the surface of the natural fiber cloth, and the natural rubber is infiltrated into the natural fiber. In the pores of the cloth, the pores of the natural fiber cloth are filled with natural rubber, and the two materials of the natural fiber cloth and the natural rubber penetrate each other to prepare a diaphragm with a good network interpenetrating structure.
[0063] The vibrating membrane is used as a vibrating membrane part of a sound generator, and can effectively improve the sound quality and fidelity effect of the generating device.
