Electromechanical transducer structure.

摘要

1. Electromechanic transducer structure composed of a passive suspension member (6) framed by two active polymer films (3, 3') of piezoelectric material having internal faces adhering to the supporting faces of said suspension member and external faces covered with electrodes (4, 4') ; an electric equipotential connection being established between said supporting faces, characterized in that said supporting faces are the faces of a film (6) of a polymer material assuring said electric equipotential connection by its inherent electric conductivity ; said polymer material offering a mechanical rigidity lower than that of said piezoelectric material.
