Abstract

Vorgeschlagen wird ein Schallerzeuger (10) zum Erzeugen von Schall mit einem vorbestimmten Frequenzspektrum, mir, einer Membran (16), die einen beweglichen Kern (18) aufweist, mit einem Aktuator (14), der auf den beweglichen Kern (18) wirkt zum Ausienken der Membran (16), und mit einer Treiberscure (40) zur Ansteuerung des Aktuators (14) mittels eines elektrischen Schaltmittels (38). Der Schallerzeuger (10) ist dadurch gekennzeichnet, dass er einen Sensor (48) aufweist, der die Bewegung des beweglichen Kerns (18) berührungslos detektiert und sobald der bewegliche Kern (18) eine bestimmte Auslenkposition (50) erreicht hat, ein Signal an die Treiberstufe (40) sendet zur Deaktivierung des Aktuators (14) durch Öffnen des elektrischen Schaltmittels (38).
