Sound transducer for receiving water sound pressure waves, sound transducer device and sonar

摘要

The invention relates to a sound transducer for receiving water sound pressure waves, wherein the transducer comprises a piezoelectric piezoelectric transducer element with a ceramic filament or a plurality of ceramic filaments and a filling compound, wherein the ceramic filament or the ceramic filaments is surrounded by the filling compound or, wherein in one Sound pressure direction is arranged a first pressure plate in front of the piezoelectric piezoelectric transducer element, so that an incident sound pressure from the pressure plate on the ceramic filament or the ceramic filaments is impressed, so that the sensitivity of the transducer is increased. Furthermore, the invention relates to a sound transducer device, a sonar for receiving water sound pressure waves and a watercraft, in particular a submarine.
