Method for producing noise in inner space of motor car, involves arranging speaker element in side wall of hose line while specific secondary sound waves are irradiated in hose line

摘要

The method involves connecting air intake system of an internal combustion engine to the inner space over sound-transmission element (6,16) of the hose line (2,12) so that by suction of the engine-excited pressure fluctuations in the form of the sound waves are transmitted into the inner space. The speaker element (7,17) is arranged in the side wall (8) of the hose line while specific secondary sound waves are irradiated in hose line. The speaker element is coupled over side spacer (11) to the hose line. An independent claim is included for device for producing noise in inner space of motor car.
