A circuit board (27) on which are mounted a piezoelectric transformer element (11) and circuit components for driving the piezoelectric transformer element (11). The piezoelectric transformer element (11) is fixed to the circuit board (27) with fixing members (33, 35) and/or support members (37, 39, 41) composed of flexible elastic material interposed between the piezoelectric transformer element (11) and the circuit board (27) so as to comprise at least nodes (29, 31) and other parts of the vibrations of the piezoelectric transformer element (11).
L'invention concerne une plaquette de circuit (27) sur laquelle on a monté un élément de transformateur piézo-électrique (11) ainsi que des composants de circuit destinés à entraîner cet élément (11). On a fixé l'élément de transformateur piézo-électrique (11) sur la plaquette de circuit (27) au moyen de pièces de fixation (33, 35) et/ou de pièces de support (37, 39, 41), composées de matériau élastique souple interposé entre l'élément de transformateur piézo-électrique (11) et la plaquette de circuit (27), de manière à comporter au moins des noeuds (29, 31) ainsi que d'autres parties destinées aux vibrations de l'élément de transformateur piézo-électrique (11).
