Abstract

Die Erfindung betrifft elektroakustische Wandler mit kleinen Abmessungen, insbesondere solche mit einem Gehäuse mit einem Außendurchmesser von 15 mm und kleiner.
Die Erfindung ist dadurch gekennzeichnet, daß er einen topfartigen Topfbauteil (11) aus einem metallisierbaren Kunststoff aufweist, der von einem Gehäuseform aufweisenden Gehäusebauteil (12) aus einem nicht metallisierbaren Kunststoff umgossen ist, und daß zumindest die innere Oberfläche des Topfbauteiles (11) mit einem Metallüberzug versehen ist.
Ausgestaltungen betreffen die Kontaktierung des Elektroakustischen Wandlers und eine Variante für radial magnetisierte Magnetplättchen.
