Abstract

PURPOSE:To obtain a diaphragm for the speaker which features a light weight, high rigidity and high internal loss by using the basic material of the span bond unwoven cloth in which the even random web is formed with the long-fiber filament composed of the organic synthetic fiber. CONSTITUTION:The long-fiber filament composed of the organic synthetic fiber is twisted round at random to from even random web 5. Then the partial heat fusing is given at point 6 between the long-fiber filaments through, for example, the needle punching method. The thickness of the filament is set preferably not more than 5 denier. In the case of the thickness of over 5 denier, it is hard to obtain the even span bond unwoven cloth and with the reduced elastisity. With use of this unwoven cloth for the basic material, a speaker diaphragm featuring a light weight, high rigidity and high internal loss can be obtained.
