Abstract

PURPOSE:To form a diaphragm for electroacoustic conversion with good conversion characteristics, by molding a composite member in which carbon fiber is thermally meet-stuck with nylon 12. CONSTITUTION:Film-shape nylon 12B is heated and meet-stuck to carbon fibers A formed into a sheet shape to obtain a composite sheet. This sheet is molded by using a heating metallic mold to obtain a cone type speaker diaphragm plate. The Young's modulus of the composite member is large with the carbon fiber A and the ratio of the Young's modulus to the density can be increased. Suitable internal loss can be given to the composite member with nylon 12B. Thus, a diaphragm for electroacoustic conversion which has the greater ratio of Young's modulus to density, the suitable internal loss and the good conversion characteristics can be formed.
