Abstract

602,661. Gramophone pick-ups. JOHNSON, A. H., and WILKINSON. G. H. Nnv. 8, 1945, No. 29766. [Class 40 (iv)] In a gramophone pick-up comprising a magnet 3, a pick-up coil 15 and an armature 10, the magnet and the armature supporting means are clamped to opposite sides of a wall 2 of a casing for the apparatus. The armature supporting means is a thin plate bolted to the casing and slotted at the middle to render it resilient and thus to permit motion of the armature which is attached at this part. The magnet is supported by its polepieces 4 which are bolted to the casing. Damping material 13 such as rubber or plastic is provided.
