Abstract:
A method of manufacturing an electroacoustic transducer, by which method a membrane configuration is produced, which membrane configuration consists of a membrane and a handling ring for the membrane connected to the membrane, and which membrane configuration is manufactured by a deep-drawing method in which a piece of foil for the manufacture of the membrane is shaped in a deep-drawing mold and is partly molded into the membrane therein and in addition is connected to the handling ring inserted into the deep-drawing mold, whereupon the handling ring and the molded piece of foil connected thereto are removed from the deep-drawing mold, and subsequently any portion of surplus foil is separated, and the membrane configuration is obtained as a result,wherein in the deep-drawing process the handling ring is first introduced into the deep-drawing mold and is brought to rest with a first axial limiting ring surface on an annular axial limiting mold surface of the deep-drawing mold, whereupon the piece of foil is shaped in the deep-drawing mold such that an interlocking connection is created between the handling ring and a foil portion of the piece of foil, which foil portion forms part of the membrane configuration, during molding of the piece of foil.
