Abstract

Cet ensemble de bras de lecture phonographique destiné à être utilisé avec un tourne-disque comporte un organe d'accouplement qui s'étend à partir d'un bras porte-cellule phonocaptrice mobile Cet organe accouple rigidement les bras avec un disque au moyen du sillon de celui-ci, tandis que le disque tourne sur le tourne-disque. L'organe d'accouplement 30 imprime un mouvement au bras de support au-dessus de la surface du disque et il isole la pointe de lecture 26 de la cellule 22 des effets d'inertie du bras lorsque cet organe d'accouplement est en contact avec le sillon du disque 18. On parvient de la sorte à un défaut d'adaptation au sillon qui est pratiquement nul et les effets du bras de lecture à l'origine de distorsion sont considérablement réduits en amplitude et en fréquence.This phonographic tonearm assembly for use with a record player has a coupling member which extends from a movable phonocaptor cartridge arm This member rigidly couples the arms to a record by means of the groove of it, while the record spins on the record player. The coupling member 30 imparts movement to the support arm above the surface of the disc and it isolates the stylus 26 of the cell 22 from the effects of inertia of the arm when this coupling member is in contact. with the groove of the disc 18. In this way, a fault in adaptation to the groove is obtained which is practically zero and the effects of the tone arm which is the source of distortion are considerably reduced in amplitude and in frequency.
