Abstract

Die Erfindung betrifft einen elektroakustischen Wandler, welcher entweder als Schallgeber oder als Schallnehmer fungiert
Die Erfindung ist dadurch gekennzeichnet, daß im Boden- und/oder Wandbereich des elektroakustischen Wandlers zumindest eine Ausnehmung (8', 8") vorgesehen ist und daß im mit diesem Wandler auszurüstenden Gerät (2', 2") zumindest ein Vorsprung (9', 9") vorgesehen ist, der bei der Montage des Wandlers (1) die Passage zwischen dem Membranvolumen (5) und dem Rückvolumen (7) definiert und so die gewünschte Hauptreibung ausbildet.
