Abstract

L'INVENTION CONCERNE LES MOTEURS ELECTRIQUES. LE VIBROMOTEUR EST DU TYPE COMPRENANT UN CONCENTRATEUR ETAGE 1 D'OSCILLATIONS DE TORSION, DONT L'UN DES ETAGES 2 EST EN CONTACT AVEC UN ELEMENT PIEZOELECTRIQUE OU PIEZOELEMENT 5, TANDIS QUE L'AUTRE ETAGE 3, OU ETAGE ENTRAINEUR, EST EN CONTACT AVEC UN ROTOR 9 DISPOSE COAXIALEMENT AU CONCENTRATEUR 1, ET EST CARACTERISE EN CE QUE L'ETAGE ENTRAINEUR 3 DU CONCENTRATEUR 1 EST REALISE SOUS FORME D'UN RESONATEUR ANNULAIRE POUR OSCILLATIONS DE TORSION. L'INVENTION PEUT ETRE UTILISEE NOTAMMENT DANS LES DISPOSITIFS D'ENREGISTREMENT ET DE REPRODUCTION DU SON, PAR EXEMPLE DANS LES ELECTROPHONES.
