Abstract (en)
[origin: WO2022096273A1] The invention relates to a device (AKS) for detecting airborne sound for automotive applications, comprising: an acoustic sensor (1); a protective grating (2) for securing the device (AKS) against penetration of coarser foreign bodies; an acoustically permeable, hydrophobic and/or lipophobic first diaphragm (5) which is located downstream of the protective grating (2) in the airflow direction (R) such that, under the action of jets of water into the opening (3a, 3b, 3c), the jets of water flow past the first diaphragm (5) and back out of the opening (3a, 3b, 3c); a sound channel (7) located in parallel with the axial axis (A), a length of the sound channel (7) being smaller than 10 mm, preferably smaller than 6 mm, particularly preferably smaller than 3 mm; and a circuit board (L) comprising components and the connections thereof for preprocessing analogue or digital signals of the acoustic sensor (1), the acoustic sensor (1) being located on one side of the circuit board (L).
