Abstract
A device includes a case (,) in which an acoustic transducer (,) is mounted so as to communicate in a water tight manner with the exterior of the case (,) via acoustic energy. The transducer (,) is mounted in front of a membrane (,) able to be deformed separating it in a water tight manner from an inlet cavity (,) which is arranged in the case (,) of the device and is in communication with the exterior. Between the membrane (,) and the transducer (,) an intermediate chamber (,) is arranged allowing deformation of the membrane by the action of external static pressure and delimited on the side of the transducer by a support element (,) fixedly mounted in the case and capable of limiting the deformation of the membrane in the event of application of the external pressure.
