Abstract (en)
An acoustic device (1) for applications in the automotive industry provided with a microphone device (3) connected to a support (2) and having a sensitive area (5); an acoustic conduit (10) designed to convey the sound pressure waves generated by an external acoustic source towards the sensitive area (5); a membrane (15) interposed between the microphone device (3) and the terminal portion (12) of the acoustic conduit (10); a grid (20) made of a metal material and arranged along the acoustic conduit (10) to protect the membrane (15) from the collision with possible bodies, which might enter the acoustic conduit (10), and to dissipate the energy of a pressurized fluid jet, which is incident on the device (1).
