ABSTRACT:
Method for providing ultraacoustic transducers of the line curtain or point matrix type, and products obtained therefrom, comprising the steps of forming a bar of piezoelectric material having any length but width and thickness almost equal to each other, metalizing the faces of this bar normal to the polarization axis, sticking one of the non-metalized faces with a face of a substrate (5), depositing at least one metallic electrode on both opposite faces of the substrate normal to the face thereof connected with the bar, connecting these electrodes (8) with the metalized faces of the bar by depositing a layer of conductive epoxy resin on both opposite faces of the substrate and coating the whole assembly with a complete jacket of epoxy resin.
