Abstract

PURPOSE:To obtain a light-weight and high-rigidity diaphragm having an appropriate loss with no breakdown in the course of manufacturing processes and under driving of the speaker by forming the entire silicon fiber or the surface into the silicon nitride and then impregnating the synthetic resin. CONSTITUTION:The silicon fiber is formed into a desired diaphram shape, and then causes the reactin to the nitrogen gas to secure the nitriding of silicon. Thus the Si3N4 layer is formed, and then the phenol resin and synthetic resin such as the methacrylic acid ester or the like are impregnated to strengthen the tackiness.
