Abstract

PURPOSE:To constitute a vibration system which is light-weight and has good heat- proof property and work efficiency, by forming a part of constituent materials of the vibration system unit for acoustic device by polyparabanic acid resin. CONSTITUTION:A speaker unit is constituted with voice coil 2 wound around voice coil bobbin 1 and domic diaphragm 3. Diaphragm 3 is formed with polyparabanic acid resin. Polyparabanic acid is light-weight and has good work efficiency and superior heat-proof property, so that an ideal vibration system can be constituted.
