Abstract

PURPOSE:To improve the durability to mechanical vibration of high power by obtaining a highly heat-resisting and lightweight diaphragm by providing a heat- resisting sheet on one surface or both surfaces of a honeycomb structure made of ceramics. CONSTITUTION:To one surface or both surfaces of ceramics-made honeycomb structure 1 of a diaphragm for an audio loudspeaker, heat-resisting sheet 2 is bonded in a body by heat-resisting adhesives. Structure 1 like this is made of a crystal group with hexangular through holes 3 and the long axis of the crystal group is oriented in one direction or surface direction. Then, the diaphragm of the loudspeaker is made highly heat-resisting and lightweight, so that the durability to mechanical vibration of high power is improved.
