Abstract

In einer Vorrichtung zur Geräuschübertragung in einem Kraftfahrzeug trennt eine innere Trennwand (2) eines Gehäuses (1, 1') zwei Teilräume (3, 4), von denen ein Anregungsraum (3) mit einem Ansaugrohr (16) einer Brennkraftmaschine und ein Ausgangsraum (4) mit einem Innenraum des Kraftfahrzeugs schallübertragend verbunden ist. Zur Schallübertragung ist eine Übertragungsklappe (6) durch eine Lageröffnung (12) der Trennwand (2) hindurchgeführt und durchsetzt beiderseits der Trennwand (2) die Teilräume (3, 4). Die Übertragungsklappe (6) ist an ihrem Rand (10) in einem schwingfähigen, an dem Gehäuse (1, 1') gehaltenen Rahmen (7) aufgenommen und im Bereich der Lageröffnung (12) mit einem die Lageröffnung (12) abdichtenden, schwingfähigen Dichtungsprofil gelagert.
Um eine Geräuschübertragung unabhängig von statischen Druckänderungen sicherzustellen, ist erfindungsgemäß ein Durchbruch (20) in der Übertragungsklappe (6) vorgesehen.
