Abstract

1,092,734. Gramophone pickups. AUDIO DYNAMICS CORPORATION. Nov. 26, 1964 [Dec. 11, 1963], No. 48034/64. Heading H4J. A stereophonic pickup, Fig. 4, comprises a housing containing two pairs of serially connected coils mounted one coil on each of the four limbs of a magnetic circuit which terminates at pole faces 28 on a plane face 30. A detachable stylus mount member 70 carries an assembly comprising a stylus, 56, and an armature, 52, pivotally mounted in an elastomeric block. In use the stylus mount 70 is pushed on to the housing so that lugs 44 engage slots 46 and positioning-ridges 64 engage face 30 so that the armature 52 is located, in its undeflected position, centrally of the pole faces 28. A magnet 62 supplies flux to the armature 52 so that deflection of the stylus induces a voltage in one or other or both of the pairs of coils depending on the direction of deflection. The stylus 56 is mounted on an arm of tubular aluminium and the coils are magnetically screened by a box 32 of material of high magnetic permeability.
