Abstract

PURPOSE:To provide an electric-to-acoustic converting apparatus, in which a fixed electrode is formed by a laminate consisting of a layer of electrically conductive material and an electrified layer of dielectric material, disposed in the manner facing toward a diaphragm, and the fixed electrode is formed with a portion projected toward the diaphragm, whereby its reactive capacity can be reduced and converting efficiency can be improved.
