Abstract

Druckkammertreiber, mit einer in einem ringförmigen Luftspalt 2 eines Magnetsystems 1 beweglichen Schwingspule 3 und mit einer von der Schwingspule 3 angetriebenen Membran. Die Membran 5 und die Druckkammer 12 sind ringförmig ausgebildet, und die Druckkammer 12 steht über ihren Umfang mit einem zentralen Schallaustrittskanal 14 in Verbindung. Die Membran 5 hat aufgrund ihrer ringförmigen Ausbildung eine große wirksame Fläche bei gleichzeitig geringer Masse. Die Speiseleistung ist daher verhältnismäßig gering, die Resonanzfrequenz ist hoch, und damit ist auch die Wiedergabetreue hoher Frequenzen verbessert. Dies ist insbesondere dann der Fall, wenn die Membran im Querschnitt V-förmig, vorzugsgweise zu dem von ihr eingeschlossenen spitzen Winkel hin gewölbt ausgebildet ist.
