ABSTRACT:
Method for providing ultraacoustic transducers of the line curtain or point matrix type, and products obtained therefrom, wherein it is provided the step of forming a bar (10) of piezoelectric material having any length but width and thickness almost equal to each other, metalizing the faces (2, 4) of this bar (10) normal to the polarization axis, sticking one of the non-metalized faces (3) with a face of a substrate (5), depositing at least one metallic electrode (8) on both opposite faces (6, 7) of the substrate (5) normal to the face thereof connected with the bar (10), connecting these electrodes (8) with the metalized faces (2, 4) of the bar (10) by depositing a layer (9) of conductive epoxy resin on both opposite faces (6, 7) of the substrate (5) and coating the whole assembly by a complete jacket (11) of epoxy resin. (FIG. 5).
