Abstract

PURPOSE:To make the control of frequency characteristic easy, by taking laminated construction for a diaphragm for speakers with a plurality types of carbide, nitride, boride and oxide of metal or semimetal, so that internal loss can be increased with high elasticity. CONSTITUTION:On one plane of a diaphragm plate member 1 made of a single metal such as Al, a TiC layer made of the 1st compound 3 is deposited, and the 2nd compound 4 is deposited on it to form a composite diaphragm 5 of TiC-TiN laminated construction. In forming the plate 5, C2H2 is supplied in a vapor-deposition furnace 11 of an evaporator 10 high vacuum to deposit a Ti metal 14 in a crucible 13 held in a base holder 12 on the surface of the member 1, and the supplying gas is replaced into N2 or NH3 to deposit the compound 4 on the TiC layer, allowing to form the composite diaphragm 5 with high elasticity and internal loss.
