Abstract

L'INVENTION A POUR OBJET UN PROCEDE ET UN DISPOSITIF POUR TRANSFORMER UNE TENSION BF EN ONDES ACOUSTIQUES OU INVERSEMENT. UN DISPOSITIF TRANSDUCTEUR ELECTRO-ACOUSTIQUE SELON L'INVENTION COMPORTE DEUX GROUPES DE POINTES 1A ET 1B SENSIBLEMENT PARALLELES QUI SONT SEPAREES PAR DES ECRANS ISOLANTS 4. LES POINTES DE CHAQUE GROUPE SONT CONNECTEES RESPECTIVEMENT A LA BORNE POSITIVE ET A LA BORNE NEGATIVE D'UNE SOURCE DE TENSION CONTINUE 3, DE L'ORDRE DE 10.000 VOLTS, QUI REND LES POINTES EMETTRICES D'UN PLASMA D'IONS. LA TENSION CONTINUE EST MODULEE PAR UNE TENSION PERIODIQUE BF. LE PLASMA D'IONS OSCILLE ET CREE DES ONDES ACOUSTIQUES QUI REPRODUISENT ANALOGIQUEMENT LA TENSION BF. UNE APPLICATION EST LA CONSTRUCTION DE HAUT-PARLEURS.
