Abstract (en)
[origin: WO0142742A1] The invention concerns a transmitter and receiver comprising several transducers arranged opposite an opening of a housing. Each transducer comprises a deformable semiconductor membrane (MB) designed to be run through by an electric current and separated by a substrate zone (ZSB1, ZSB2) by a cavity enabling the membrane to be deformed under the effect of acoustic pressure of a Lorenz force.
