Abstract
Dispositif électroacoustique Dispositif électroacoustique (5) comportant :- un transducteur (15) d’onde ultrasonore comportant un substrat (10) piézoélectrique et des première (30) et deuxième (35) électrodes en contact avec le substrat piézoélectrique, et - un support (10), le transducteur étant fixé sur le support et couplé acoustiquement avec le support, et les première et deuxième électrodes étant prises en sandwich, au moins en partie, entre le substrat piézoélectrique et le support,le dispositif étant configuré pour générer une onde de surface ultrasonore (W) se propageant dans le support à distance du transducteur, lorsqu’un courant électrique parcourt les première et deuxième électrodes.
