A method of producing cone diaphragm having color patterns includes steps of using a fiber-made thin sheet as a base material; printing the base material with a high molecular ink; soaking the printed base material in a high molecular resin material; or alternatively, first soaking the base material in the high molecular resin material and drying the base material, and then printing the base material wish the high molecular ink; so that the base material is coated with a layer of the high molecular resin to maintain a desired brilliance of the color patterns; drying the base material and positioning it in a high-temperature mold, so that the base material is molded into a cone having a predetermined shape; painting outer surfaces of the molded cone with a paint; and trimming the molded and painted cone to produce a finished cone diaphragm having color patterns.
