Sound channel and housing for acoustic sensors for a vehicle for detecting sound waves of an acoustic signal outside the vehicle

摘要

Sound channel (10) for an acoustic sensor (1) for a vehicle (20) for detecting sound waves (2) of an acoustic signal outside the vehicle (20), comprising an input area (11) for the sound waves (2) into the sound channel ( 10) and a conduit area (12) to guide the sound waves (2) to a sound transducer (1a) of the acoustic sensor (1), a first layer () between the input area (11) and the conduction area (12) 13) is arranged, which is designed to pass the sound waves (2) from the input area (11) into the line area (12) and at least to dampen interferences that impair detection of the acoustic signal, and the line area (12) a second one Layer (14), which is water and / or wind tight and is designed to guide the sound waves (2) to the sound transducer (1a) in order to make the sound waves (2) essentially free of interference with little attenuation of the sound waves (2 ) to be detected. The invention further relates to a housing (30), a vehicle (20) and a method for mounting the housing (30) for acoustic sensors (1, 3, 4, 5) of the vehicle (20) for detecting sound waves (10). an acoustic signal outside the vehicle (20).
