Abstract
a. Transducteur électrodynamique notamment pour la lecture de disques phonographiques. b. Transducteur caractérisé en ce que les bobines sont situées au voisinage de l'extrémité de la seconde pièce polaire pour couper le flux passant entre la première et la seconde pièces polaires, le flux entre les bobines variant en fonction du mouvement de pivotement de l'organe vibrant autour du centre d'oscillation dans la région de l'organe d'amortissement, créant ainsi des signaux de tension aux bornes des bobines.
