Abstract

Die Erfindung betrifft eine elektroakustische Kapsel bzw. einen elektroakustischer Wandler für ein elektroakustisches Gerät
Die Erfindung ist dadurch gekennzeichnet, dass sie und/oder er elektrostriktive oder magnetostriktive Elemente, bevorzugt piezoelektrische Bauteile, aufweist, die mit einer regelbaren Spannungsquelle in Verbindung stehen und dass die Abmessungsänderungen der elektrostriktiven bzw. magnetostriktiven Elemente Änderungen in der inneren Geometrie der Kapsel bzw. des Wandlers nach sich ziehen.
Dadurch läßt sich die Akustik an das jeweilige Gerät anpassen, es sind auch individuelle und dynamische Anpassungen möglich.
