Abstract

Improved transducer characterized by a piezoelectric element having its opposite main surfaces provided with electrodes attached to them; a second element having its main opposite surfaces defining an area that extends over at least the entire extension of one of the main surfaces of said piezoelectric element; and an elastomeric intermediate layer provided with a surface fastened on said main surface of said piezoelectric element and an opposite surface fastened to said main surface that extends over the entire extension of said second element.
