Abstract

PURPOSE:To obtain a speaker diaphragm superior in stiffness, lightness and productivity by laminating a plastic film onto both faces or one face of a punching metal. CONSTITUTION:Thermoplastic plastic film 12 is laminated onto both faces or one face of disc-shaped metallic plate 11 which consists of aluminum, titanium, beryllium, etc., and has many holes. A plane plate obtained in this manner is shaped into domic or conic form by heat treatment and is made into a speaker diaphragm.
