Abstract

PURPOSE:To produce a light-weight and high-strength plane plate-form diaphragm easily, by forming many parallel folds on thin materials and by driving them by a bellows-shaped edge part and a rectangular voice coil. CONSTITUTION:In the speaker which has a plane plate-form diaphragm and gives importance to the tone quality, the plane plate-form diaphragm 1 is produced by forming many parallel wave-shaped or radial folds on thin materials. It is driven by a rectangular voice coil 2 and a bellows-shaped edge 3. Thus, a light-weight and high-strength plane plate-form diaphragm is produced easily, and the bellows-shaped edge functions effectively for a large amplitude.
