Abstract

TRANSDUCTEUR POUR LA TRANSFORMATION DE MODULATIONS ELECTRIQUES EN MODULATIONS VIBRATOIRES, COMPRENANT UNE ELECTRODE DE DECHARGE EN FORME D'AIGUILLE, QUI EST NOYEE, EXCEPTE DANS LA REGION DE SA POINTE, DANS UN PORTE-ELECTRODE DE FORME SENSIBLEMENT CYLINDRIQUE EN UNE MATIERE ELECTRIQUEMENT ISOLANTE ET RESISTANT A LA CHALEUR, ET UNE CONTRE-ELECTRODE ESPACEE DE L'ELECTRODE DE DECHARGE ET ENTOURANT CELLE-CI. LA CONTRE-ELECTRODE 5 A SENSIBLEMENT LA FORME D'UNE SPHERE REALISEE EN UN MATERIAU ELECTRIQUEMENT CONDUCTEUR AJOURE PERMEABLE AUX ONDES SONORES, ET COMPORTE UN PASSAGE 7 DANS LEQUEL EST EMBOITE LE PORTE-ELECTRODE 3. L'ELECTRODE DE DECHARGE 1 S'ETEND RADIALEMENT A L'INTERIEUR DE LA CONTRE-ELECTRODE SPHERIQUE 5 JUSQU'A UN POINT SITUE A PROXIMITE DU CENTRE DE LA SPHERE. LE TRANSDUCTEUR AINSI REALISE EST OMNIDIRECTIONNEL.
