Abstract

PURPOSE:To enable to obtain the reproduced tone with high fidelity, by constituting the sheet of Al foil and plastic film through lamination with thermosetting adhesives such as urethane and epoxy system. CONSTITUTION:Al foil 1 and plastic film 3 are laminated into sheet with the thermosetting adhesives 2 such as urethane and epoxy system to constitute the member of speaker vibration plate. Thus, the internal loss is suitably greater and modulus of elasticity is high and the rigidity is greater, and the vibration plate of uniform thickness can be obtained. Further, the sound pressure frequency characteristics are made flat at a wide variety of frequency band and the reproducing sound with high fidelity can be obtained.
