Abstract

PURPOSE:To improve the durability to mechanical vibration of high power by obtaining a lightweight diaphragm of high thermal resistance by providing a ceramic this film on at least one surface of a honeycomb structure of thermal resistance. CONSTITUTION:To one surface or both surfaces of heat-resisting honeycomb structure 1 or 10 of a diaphragm for an audio loudspeaker, ceramic thin film 2 is stuck in a body. This ceramic thin film 2 is manufactured with a thickness of 150mum by extrusion, doctor-blade formation, a means of forming it by adsorbing a ceramic slurry or paste to a sheet of hygroscopic paper, cloth, etc., and then sintering it, vapor deposition, melt spraying, etc. Then, the diaphragm is made highly heat- resisting and lightweight, so that the durability to mechanical vibration of high power is improved.
