SOUND TRANSDUCER FOR SENDING AND/OR FOR RECEIVING UNDERWATER ACOUSTIC SIGNALS, TRANSDUCER DEVICE, SONAR, AND WATERCRAFT

摘要

The invention relates to a sound transducer for sending and/or for receiving underwater acoustic signals, which transducer has an acoustic transducer element, at least one first spring element, a filling compound and a transducer support, wherein the acoustic transducer element is designed as a first mass and the first spring element and the transducer support attached thereto are arranged behind the acoustic transducer element with respect to a sound pressure direction, such that an oscillating system is established and thus an acoustic sensitivity of the sound transducer is improved. The invention also relates to a transducer device, a sonar for sending and/or for receiving underwater acoustic signals and a watercraft.
