Abstract

301,227. Dieux, J. Jan. 3, 1928. Gramophone pickups ; magnetic instruments. - In an electromagnetic device for reproducing sound from records. the armature constituting the stylus-bar is bent and dimensioned to amplify its movement adjacent the magnet. The bar 12 rocking a pivot 8 may have an enlargement or enlargements 14 between or opposite to the magnet poles or be constructed with a T-head opposite these poles to increase the magnetic effect.
