Abstract

PURPOSE:To obtain the diaphragm plate possible for thin speaker mounting and higher in sound effect, by forming ribbed oscillation plate with a pair of press molds easy for manufacture. CONSTITUTION:The press mold 11 is constituted with the upper mold 12 and the lower mold 13. The upper mold 12 has the projection 14 of cone shape at the center of the axial direction of cylindrical shape and the cylindrical projection 15 at the outside of circumference direction. The cone surface 16 of cone shape is provided with the rib mold section 17 of radial shape. The lower mold 13 has cylinder and has the concave 18 of cone shape at the axial center. The external circumferential wall is formed so that it fits to the internal circumferential wall of the projection 15. The flexible resin film 19 is inserted between the upper and lower molds 12 and 13 for heat pressuing. Thus, the diaphragm can be manufactured with economy.
