Abstract

Erfindungsgemäß wird eine Baßwiedergabeanordnung angegeben, bei welcher die Schallabstrahlung von der Membran (15) zum Abhörraum (38) allein über ein Verschiebevolumen (37) und mindestens einen Schallführungskanal (34), dessen Querschnitt kleiner ist als der Querschnitt der Membran (15), erfolgt. Eine solche Anordnung hat den Vorteil, daß zur Schallabstrahlung nur Wandflächen bereitgestellt werden müssen, die lediglich den oder die Schallführungskanäle (34) aufnehmen müssen. Die Seite der Membran (15), welche dem Verschiebevolumen (37) abgewandt ist, arbeitet auf ein geschlossenes Dämpfungsvolumen (30), welches allerdings in großer Bandbreite in seiner Größe veränderbar ist. Eine besonders gute Baßwiedergabe wird dann erreicht, wenn die Länge des jeweiligen Schallführungskanals (34) ≤ λ/8 der gewünschten oberen Grenzfrequenz ist.
