Abstract

PURPOSE:To obtain an audio loudspeaker diaphragm that is lightweight, has high heat-resisting property and is tolerant of powerful mechanical vibration, by molding it with heat-proof resin consisting essentially of powdery, fibriform and spicular ceramics. CONSTITUTION:Fibriform or spicular ceramics obtained from a ceramic material in the form of single crystal or polycrystal is essentially used and oriented in a surface shape with heat-proof resin to mold a cone type molded body and plate type molded body, which are used as diaphragms. Therefore, the high heat-resisting property can sufficiently be displayed and the thickness can extremely be reduced. Consequently, the weight can be reduced and sufficient durability against mechanical vibration can be provided.
