Abstract
An apparatus for transmitting sound in a motor vehicle having a housing () with an inner partition (), which together define two separate subspaces (). A transmission valve () which separates the two subspaces () is provided in a pivot bearing opening () in the partition () and is mounted to pivot about a pivot axis () in the area of the pivot bearing opening (). The first subspace () is connected in a manner capable of transmitting sound to an intake manifold () of an internal combustion engine, and the second subspace () is connected in a manner capable of transmitting sound to an interior space of the motor vehicle. The gap () between an edge () of the pivot bearing opening () and the transmission valve () is sealed in a pressure-tight manner by a membrane ().
