Patent attributes
The invention relates to an electroacoustic transducer arrangement for underwater antennas comprising: interspaced transducer elements (11); a reflector (12) that, in a sound incidence direction, is situated behind the transducer elements (11), with the reflector being comprised of a metal plate (13) facing the transducer elements (11) and of a foam material plate (14) located on the side of the metal plate (13) facing away from the transducer elements (11), and; an elastomer hard enclosing cast that encloses the transducer elements (11) and the reflector (12). 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 (13) has a honeycomb structure, and a double layer (15) consisting of a foam material layer (16) adjacent to the metal plate (13) and of a cork layer (17) adjacent to the foam material plate (14) are arranged between the metal plate (13) and the foam material plate (14).
