Abstract

L'INVENTION CONCERNE LES TRANSDUCTEURS ELECTROMECANIQUES. UN TRANSDUCTEUR ELECTROMECANIQUE A FLEXION COMPREND UNE LAME DE CERAMIQUE PIEZOELECTRIQUE 21 INTERCALEE ENTRE DEUX LAMES METALLIQUES 19, 20. UN SIGNAL DE FREQUENCE DONNEE EST APPLIQUE AU TRANSDUCTEUR DANS UNE DIRECTION PARALLELE A LA DIRECTION DE POLARISATION RESIDUELLE DE LA CERAMIQUE PIEZOELECTRIQUE, CE QUI PRODUIT UNE VIBRATION DE LA LAME DE CERAMIQUE EN MODE CISAILLEMENT-EPAISSEUR. CETTE VIBRATION EXCITE A SON TOUR UNE VIBRATION DE FLEXION DU TRANSDUCTEUR. APPLICATION AUX FILTRES ELECTROMECANIQUES.
