Apparatus for transmitting sound in a motor vehicle

An apparatus for transmitting sound in a motor vehicle, said apparatus comprising a housing with an inner partition which together define two separate subspaces, and a transmission valve disposed in a pivot bearing opening in said partition separating the two subspaces and mounted to pivot about a pivot axis in the area of the pivot bearing opening;

• wherein one of said subspaces is connected to an intake manifold of an internal combustion engine, the other of said subspaces is connected to an interior space of the motor vehicle in a manner capable of transmitting sound, and a gap between an edge, corresponding to a free end of the respective section of the partition facing inward, of the pivot bearing opening and the transmission valve is sealed on both sides of the transmission valve in a pressure-tight manner by a membrane that is rigid in its plane and secures the transmission valve in at least one of the plane of the membrane and the plane of the partition.
