Abstract
Bei einem als sog. Ringwandler ausgebildeten elektroakustischen Wandler, insbesondere für Unterwassereinsatz, ist zwecks Schaffung eines leistungsstarken Wandlers zu niedrigen Herstellkosten der Ringkörper (10) des Wandlers mit einer Mehrzahl von um gleiche Drehwinkelabstände zueinander versetzte Axialschlitze (13) versehen, die mit Abstand vor den beiden Stirnseiten des Ringkörpers (10) enden. Die Keramikplatten (11, 12) liegen paarweise mit entgegengesetzter Polarisation in den Axialschlitzen (13) ein und werden durch den Ringkörper (10) aneinandergepreßt. In the case of an electroacoustic transducer designed as a so-called ring transducer, in particular for underwater use, the annular body (10) of the transducer is provided with a plurality of axial slots (13) offset from one another by the same rotational angular spacing in order to create a powerful transducer at low manufacturing costs, which are spaced apart from the both ends of the ring body (10) end. The ceramic plates (11, 12) lie in pairs with opposite polarization in the axial slots (13) and are pressed together by the ring body (10).
