Abstract

PURPOSE:To reduce high frequency resonant peak without lowering reproducing frequency band, by providing a partial slit shape notch for at least one of surface members, when the surface members are bonded on the surface of a core member to constitute a vibration diaphragm for speaker with sandwich construction. CONSTITUTION:Surface members 2, 2' made of aluminum foil about 30mum thickness are bonded on both the sides of a honey-comb core member 1 by using film-like bonding agents 3, 3' and form the concentric partial slit notches 6 on at least one surface member of the member, 2, 2'. When the notches 6 are given to both the members 2, 2', the location of notch are made different for the members 2 and 2'. Thereafter, a cylindrical coil bobbin 4 is fixed where a voice coil 5 is wound at the center of the member 2, this diaphragm is supported to the frame via an edge member and the coil 5 is inserted to a ring magnetic gap of a magnetic circuit.
