Abstract
A vibrating diaphragm includes a diaphragm body and a suspension edge. The diaphragm body is made by acrylonitrile butadiene styrene materials. A surface of the diaphragm body is electroplated a layer of nanoscale materials. The suspension edge is made by room temperature vulcanized silicone rubber materials. The suspension edge is molded an outer periphery of the diaphragm body. The vibrating diaphragm can improve the high frequency effect of the speaker.
Claims4
A vibrating diaphragm mounted on a speaker, comprising:
- a diaphragm body made by acrylonitrile butadiene styrene materials, a surface of the diaphragm body being electroplated a layer of nanoscale materials;
- and
- a suspension edge made by room temperature vulcanized silicone rubber materials, the suspension edge being molded with an outer periphery of the diaphragm body.
A manufacture method of the vibrating diaphragm, comprising:
- step one:
- molding a circular-shaped diaphragm body using acrylonitrile butadiene styrene materials;
- step two:
- electroplating a layer of nanoscale materials to the surface of the diaphragm body;
- step three:
- placing the diaphragm body in a mould, and molding the room temperature vulcanization silicone rubber on the outer periphery of the diaphragm body to form an annular-shaped suspended edge, the inner periphery of the suspension edge having an annular-shaped slot, the outer periphery of the diaphragm body fixed in the slot of the suspension edge, and the centers of the diaphragm body and the suspension edge being the same.
