Abstract

PURPOSE:To achieve flat high frequency sound and to obtain a diaphragm plate excellent in heat resistance and anti-input performance, by forming a voice coil via an insultion layer on one side of a diaphragm plate base made of metal. CONSTITUTION:A voice coil 11 is provided in spiral on one surface of a diaphragm plate base 10 for speaker, and an insulation layer 3 is formed on either one of the base 10 and the coil 11. In manufacturing the speaker use diaphragm plate, almite treatment is made on one side of an Al foil plate 1 to form an insulation layer 2, and after a metal film 3 such as berylloim is vapor deposited on the surface of the insulation layer 2 and a resist layer corresponding to the coil 11 is provided on the surface of the foil plate 1, the coil plate 1 for the part without the resist layer is removed with etching processing to form the metal film 3 as the diaphragm plate base 10, and the diaphragm plate can be constituted by taking the remaining part of the foil plate 1 as the coil 11. The high frequency sound can be expressed flat and the diaphragm plate excellent in heat resistance and anti-input performance can be obtd.
