The invention relates to a transducer device for transmitting and/or receiving acoustic underwater signals, which has a transducer carrier and an acoustic absorber, wherein an acoustic transducer element is arranged on the transducer carrier and first the transducer carrier and then the acoustic absorber are arranged one behind the other in a sound pressure direction, wherein the transducer carrier is elastically formed, and so the elastic transducer carrier can undergo mechanical oscillation and is substantially isolated from the acoustic absorber, and so the acoustic absorber remains intact when a shock sound pressure wave impinges on the transducer device. The invention also relates to a transducer apparatus comprising two or more transducer devices, to a sonar and to a water craft.
