1. A method of manufacturing a 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 a surface of the diaphragm body; step three: placing the diaphragm body in a mold, and molding a room temperature vulcanization silicone rubber on an outer periphery of the diaphragm body to form an annular-shaped suspended edge, an inner periphery of the suspension edge having an annular-shaped slot, an 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.
