摘要： A microphone unit having only one PCB, a plurality of transducers of acoustic-electric type with digital output mounted on a back side of the PCB, through holes obtained in the PCB in correspondence with each transducer, an A2B audio interface mounted on the back side of the PCB and electrically connected to the transducers; and input/output electrical connectors mounted on the back side of the PCB and electrically connected to said A2B audio interface; the plurality of transducers include a central transducer and at least three peripheral transducers disposed at the same radial distance from the central transducer and equally angularly spaced. A microphone meta-array includes a plurality of microphone units connected by one or more A2b networks.

摘要： A system for monitoring an acoustic scene outside a vehicle; the system including: a vehicle with wheels and a trunk, an acoustic sensor disposed in the trunk, a control unit operatively connected to the acoustic sensor, and at least one neural network operatively connected to the control unit, and trained in such a way to correlate the characteristics of an audio signal with types of road surfaces; the control unit is configured in such a way to receive an audio signal detected by the acoustic sensor while the vehicle is traveling, extract the characteristics of the audio signal and input said characteristics of the audio signal to the neural network in order to identify the type of road surface covered by the vehicle wheels.

摘要： A manufacturing method of a microphone is disclosed, wherein a patterned upper electrode is obtained by a first deposition of conductive material in such a way to form pads of the patterned electrode, and pillars are formed by of successive depositions of rigid conductive material, in aligned position on the pads of the patterned electrode. The first deposition and the successive depositions are made by screen-printing, dispenser-printing or spray-coating of material in liquid or semifluid state.
