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.
