Patent ID: 7188703

Claim:
A device for establishing noise in a motor vehicle having an internal combustion engine ( 1 ) with a gas carrying part ( 2 ), said device comprising a housing ( 6 ), which has an inlet space ( 8 ), an inlet line ( 3 ) connected to said inlet space ( 8 ) and to said gas-carrying part ( 2 ) of said internal combustion engine ( 1 ), an outlet space ( 9 ), which is acoustically coupled by means of an outlet line ( 10 ) to at least one of an interior space of the motor vehicle and the space surrounding the vehicle, an acoustically substantially inactive wall ( 7 ) separating said inlet space ( 8 ) from the outlet space ( 9 ), and a sound transmission device ( 11 ) including, at least two vibratable elements ( 12 , 13 ), one of which ( 12 ) is arranged in the inlet space ( 8 ) and the other ( 13 ) of which is arranged in the outlet space ( 9 ), said at least two vibratable elements ( 12 , 13 ) being connected to each other by means of a curved connecting element ( 16 ), which is mounted on the acoustically inactive wall ( 7 ), in such a way that, when the vibratable element ( 12 ) arranged in the inlet space ( 8 ) is subjected to the sound introduced through the inlet line ( 3 ), the connecting element ( 16 ) performs a pivot movement, transmitting the vibrations of the vibratable element ( 12 ) arranged in the inlet space ( 8 ) to the vibratable element ( 13 ) arranged in the outlet space ( 9 ).
