摘要： An electroacoustic transducer, in particular a transmitting transducer for sonar systems, is disclosed, comprising two end caps (11, 12) that are arranged at a fixed distance from each other, multiple bars (13) which are braced between the two end caps (11, 12) and the ends of which are attached to the end caps (11, 12) next to each other in the peripheral direction, and an elastic shell (16) that externally encloses the bars (13). In order to significantly reduce the weight of the transducer and simplify production, composite modules (17) are attached to the bars (13) so as to excite vibrations. Each composite module (17) has electrode structures that include spaced-apart electrodes and are arranged on at least two film layers made of insulating material, and spaced-apart piezoceramic fibers which are arranged between the film layers and are contacted by the electrodes on opposite longitudinal sides.

摘要： An electroacoustic underwater antenna, particularly a lateral antenna which can be fixed to the outer hull of an underwater craft, comprising a series of hydrophones (13) successively arranged in at least one elongate, closed, oil-filled cavity at a distance from each other. The aim of the invention is to achieve a high degree of reception sensitivity in the low frequency range with a sufficiently small, vertical aperture angle. The inventive device is easy to produce and mount and is characterized by several cavities (14) which are fitted with hydrophones (13) at a parallel distance from each other, arranged in front of a rigid plate (12) at a distance therefrom, and the plate (12) and cavities (14) are embedded in a panel-type, acoustically transparent plastic element (11). Several of said plastic elements (11) are arranged close to each other or behind each other. .

摘要： The invention relates to a sound transducer for receiving underwater sound waves, having an acoustic transducer element and a cover plate. The cover plate has a recess and at least one parameter, and the parameter is a thickness and/or a material and/or a geometric arrangement of the cover plate. The cover plate is paired with the acoustic transducer element such that an underwater sound wave impinges upon both the cover plate as well as the acoustic transducer element. The at least one parameter is set such that an angle dependence of a sound reflection is adjusted for an impinging underwater sound wave so as to increase the sensitivity of the sound transducer. The invention further relates to a sound transducer, a sonar, and a watercraft.

摘要： The invention relates to an acoustic transducer for receiving waterborne sound shock waves, wherein the acoustic transducer comprises an acoustic piezoelectric patch transducer element having a ceramic filament or a plurality of ceramic filaments and comprises a filling compound, wherein the ceramic filament or the ceramic filaments is or are surrounded by the filling compound. A first pressure plate is arranged before the acoustic piezoelectric patch transducer element in a sound shock direction, such that an impinging sound shock from the pressure plate is imposed on the ceramic filament or the ceramic filaments, such that the sensitivity of the acoustic transducer is increased. The invention further relates to an acoustic transducer device, to a sonar for receiving waterborne sound shock waves, and to a water craft, in particular a submarine.

摘要： An electroacoustic transducer (10) is disclosed, comprising a ring member (11) that contains piezoceramic material and electrodes which contact said material. In order to keep the size and weight of the transducer (10) low while obtaining a sufficiently high acoustic power, the ring member (11) is composed of multiple annular, flat composite modules (16) which rest against each other in the radial direction of the ring member (11). Each composite module (16) has axially spaced-apart piezoceramic fibers which extend in the circumferential direction of the ring member (11), and spaced-apart electrodes which extend transverse to the piezoceramic fibers and contact the same on the longitudinal sides thereof that are radially opposite each other.

摘要： The invention relates to an electroacoustic transducer comprising an actuator (11), which oscillates longitudinally when an alternating voltage is applied. In order to substantially reduce the weight of the transducer while maintaining a sufficiently high sound power, especially transmission power, the actuator (11) consists of a tube (14), especially a plastic tube, and at least one composite module (15) that is rigidly connected to the tube wall (141) of the tube. The at least one composite module (15) comprises electrode structures which are arranged on at least two film layers of an electrically insulating material and which have interspaced electrodes and interspaced piezoceramic fibers that are arranged between the film layers and are contacted by the electrodes on ends facing away from each other.

摘要： 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), said 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).
