<p>The subject of the present invention are underwater electro-acoustic transducers and a method for manufacturing these transducers. A transducer according to the invention comprises, in a cylindrical casing (3), a first stack of piezoelectric plates (washers) (6) coaxial with the second stack. It comprises a top (1) and a counter-mass (2). It comprises a rigid part (8) which is inserted between the first and the second stacks. A first end (A) of the first stack bears against a bearing face (1A) of the top. A first end (D) of the second stack bears against a bearing face (2A) of the counter-mass. The two ends (B and C) of the two stacks bear against bearing faces (81 and 82) of the intermediate part. One application is the construction of underwater electro-acoustic transducers of high power per unit volume. <IMAGE></p> |
