Abstract

PURPOSE:To produce a speaker diaphragm having an even quality through a simple process, by realizing a one-shot working for both formation of diaphragm is which diaphragm member is molded with heat and pressure and the formation of an edge member. CONSTITUTION:The diaphragm member S is formed by cutting a light-weight material having the same mass over the entire surface into a fan shape. A resin layer is coated over the base fabric and then cut into a preformation shape to obtain the edge member E. The fixed mold 10 and mobile mold 20 are kept at the temperatures suited for each forming secured by the heaters 18 and 23, and then the member S is put onto the diaphragm formation part 11 with the both edges of the fan shape are connected together with an adhesion. The edge member E is put on the port of the edge formation part so that the resin layer is set at the upper side. Then the mold 20 is shifted toward the mold 10, and the members S and 11 are formed with heat and pressure at the formation parts 11 and 21 plus 12 and 22 each. At the same time, the both members are unified within the hollow groove 12c to obtain a diaphragm.
