Abstract

Ein elektromagnetischer Wandler (1) zur Schallerzeugung in elektronischen Hörgeräten weist ein Gehäuse (2) und einen im Gehäuse angeordneten elektromagnetischen Antrieb mit einer Spule (4), einem Antriebsmagneten (5) und einer Ankeranordnung (6) auf. Ferner ist im Gehäuse eine Membranenanordnung vorgesehen, die mechanisch an die Ankeranordnung (6) angekoppelt ist. Zur Reduzierung von Vibrationen durch die antreibenden und angetriebenen Teile des Wandlers sowie zur Verbesserung des Wirkungsgrades umfaßt die Membranenanordnung zwei gesonderte Membranen (7, 7'), die auf sich gegenüberliegenden Seiten des Antriebs (3) angeordnet, identisch ausgebildet und derart gegenläufig antreibbar sind, daß der durch die Bewegung der angetriebenen oder antreibenden Teile auftretende mechanische Gesamtimpuls minimiert ist.
