Abstract

611,184. Gramophone pick-ups. TRUVOX ENGINEERING CO., Ltd., and CLARK, F. April 24, 1946, No. 12423. [Class 40 (iv)] In a suspension and damping arrangement for the moving element in a gramophone pickup, a cylindrical member 20 carrying moving coils 22 surrounds a rigidly mounted pin 30, the intervening space between the cylindrical member 20 and the pin 30 being filled with a resilient material 29 under radial compression. The coils 22 are wound on ears or ribs 21, and the ends of the coil are carried to a terminal mounting 25. The stylus 26 is set in a projection 27 on the cylindrical member 20. The rod 30 is mounted in non-magnetic end plates 11, between which the polepieces 13 and the U-shaped magnet 15 are clamped.
