Abstract

L'INVENTION CONCERNE LES MOTEURS ELECTRIQUES. LE VIBROMOTEUR FAISANT L'OBJET DE L'INVENTION EST CARACTERISE EN CE QUE LES MOYENS DE TRANSFORMATION DES OSCILLATIONS DU PIEZO-ELEMENT EN OSCILLATIONS DE TORSION SE PRESENTENT SOUS FORME DE BARRES DISPOSEES SUR LA SURFACE LATERALE DU PREMIER ETAGE, DANS UN PLAN PERPENDICULAIRE A L'AXE DU CONCENTRATEUR, ET SONT INCLINEES SOUS UN ANGLE AIGU PAR RAPPORT A LA TANGENTE, AU POINT DE FIXATION DE LA BARRE, A LA LIGNE D'INTERSECTION DE LADITE SURFACE LATERALE ET DUDIT PLAN, CES BARRES SERVANT DE RESONATEURS POUR LES OSCILLATIONS LONGITUDINALES SE PROPAGEANT DANS LESDITES BARRES. LE VIBROMOTEUR EN QUESTION PEUT ETRE UTILISE EN PARTICULIER DANS LES DISPOSITIFS D'ENREGISTREMENT ET DE REPRODUCTION DU SON, PAR EXEMPLE DANS LES ELECTROPHONES.THE INVENTION CONCERNS ELECTRIC MOTORS. THE VIBROMOTOR WHICH IS THE OBJECT OF THE INVENTION IS CHARACTERIZED IN THAT THE MEANS OF TRANSFORMATION OF THE OSCILLATIONS OF THE PIEZO-ELEMENT INTO TORSION OSCILLATIONS ARE IN THE FORM OF BARS ARRANGED ON THE LATERAL SURFACE OF THE FIRST FLOOR, IN A PERPENDICULAR PLANE TO L 'AXIS OF THE CONCENTRATOR, AND ARE INCLINED AT AN ACUTE ANGLE WITH RESPECT TO THE TANGENT, AT THE FIXING POINT OF THE BAR, AT THE LINE OF INTERSECTION OF THE SAID LATERAL SURFACE AND OF THE SAID PLAN, THESE BARS ACTING AS RESONATORS FOR THE LONGITUDINAL OSCILLATIONS. PROPAGATING IN THE SAID BARS. THE VIBROMOTOR IN QUESTION CAN BE USED IN PARTICULAR IN SOUND RECORDING AND REPRODUCTION DEVICES, FOR EXAMPLE IN ELECTROPHONES.
