<p>A cone diaphragm having color patterns is produced by soaking the printed base material in high molecular weight resin material, printing a layer of high molecular ink over the base material to produce predetermined color patterns on the base material, and drying and molding the resin coated and printed base material to attach the high molecular ink with the base material. Production of a cone diaphragm having color patterns, comprises selecting a base material of thin sheet fiber material, soaking the printed base material in a high molecular weight resin material, printing a layer of high molecular ink over the base material to produce predetermined color patterns on the base material, drying the resin coated and printed base material to attach the high molecular ink with the base material, molding the dried base material in a high-temperature mold to form a molded cone having a predetermined shape, coating surfaces of the molded cone with a layer of paint, drying the molded and painted cone, and trimming the dried cone to produce a finished product.</p> |
