Abstract (en)
[origin: WO2020224904A1] The invention relates to a device (AKS) for detecting airborne sound for automotive applications in which there are air flows between the device (AKS) and a sound source of the airborne sound, the device (AKS) comprising: - an acoustic sensor (1); - a protective grille (2) for protecting the device (AKS) from the ingress of foreign bodies; - an acoustically permeable, hydrophobic and/or lipophobic first membrane (5); - a flow bypass (6), which runs between the protective grille (2) and the first membrane (5); - a sound channel (7); and - a circuit board (L), the circuit board (L) comprising components and connections thereof for pre-processing analog or digital signals of the acoustic sensor (1) and a circuit board opening (4), the acoustic sensor (1) being arranged on the circuit board opening on the side of the circuit board (L) that is rearward in the air flow direction (R).
