Abstract
The invention relates to an electroacoustic transducer arrangement for underwater antennas comprising: interspaced transducer elements (); a reflector () that, in a sound incidence direction, is situated behind the transducer elements (), with the reflector being comprised of a metal plate () facing the transducer elements () and of a foam material plate () located on the side of the metal plate () facing away from the transducer elements (), and; an elastomer hard enclosing cast that encloses the transducer elements () and the reflector (). The aim of the invention is to obtain a lightweight transducer arrangement with unchanged favorable performance data whereby having a broadened field of application. To this end, the metal plate () has a honeycomb structure, and a double layer () consisting of a foam material layer () adjacent to the metal plate () and of a cork layer () adjacent to the foam material plate () are arranged between the metal plate () and the foam material plate ().
