| titleOfInvention | Vibrating diaphragm and manufacturing method thereof |
| abstract | The invention relates to a diaphragm and a manufacturing method thereof, wherein the manufacturing method comprises the following steps: s1: providing a silica gel film; s2: treating the silica gel film to obtain silica gelThinning the film to form a silica gel film; s3: providing graphene, graphite powder, a diluent and glue; s4: adding graphene or a mixture of graphene and graphite powder into a diluent, and uniformly mixing to form a graphene suspension or a graphene-graphite powder suspension; s5: uniformly coating a graphene suspension or a graphene-graphite powder suspension on the surface of a silica gel film, and drying to form a middle layer, wherein the middle layer is a graphene layer or a graphene-graphite powder layer; s6: uniformly coating glue on the surface of the middle layer and drying the glue to enable the glue to be solidified on the surface of the middle layer to form a glue layer, and finally forming a film; and S7, forming and dividing the film into finished diaphragms in a hot pressing mode. The vibrating diaphragm adopts the silica gel film as a base material, so that the resonance problem is better inhibited, the distortion degree of the vibrating diaphragm is reduced, and the resonance frequency f 0 Lower, better low frequency characteristics. |
