Abstract

Es wird ein elektroakustischer Wandler, insbesondere Sendewandler für Sonarsysteme, angegeben, der zwei im festen Abstand voneinander angeordnete Endkappen (11, 12), mehrere, zwischen den beiden Endkappen (11, 12) aufgespannte, endseitig an den Endkappen (11, 12) in Umfangsrichtung nebeneinander festgelegte Lamellen (13) und eine die Lamellen (13) außen umschließende, elastische Hülle (16) aufweist. Zwecks deutlicher Reduzierung des Wandlergewichts bei vereinfachter Fertigung sind zur Schwingungsanregung an den Lamellen (13) Composite-Module (17) festgelegt, wobei jedes Composite-Modul (17) auf mindestens zwei Filmschichten aus isolierendem Material angeordnete Elektrodenstrukturen mit voneinander beabstandeten Elektroden und zwischen den Filmschichten angeordnete, voneinander beabstandete Piezokeramikfasern aufweist, die auf voneinander abgekehrten Längsseiten von den Elektroden kontaktiert sind.
