Abstract

609,052. Sound-reproducing devices. COOPER, R. M. C. March 5, 1946, Nos. 6757 and 9588. [Class 40 (iv)] In a gramophone pickup an elongated coil 1 is fixed inside a cylindrical tube 5 to which a stylus holder 13 is secured. The tube is rotatably mounted in a bore in a bearing member 19 mounted between the pole tips of the magnet system. Resilient means 41 surround the holder 13 in the aperture provided for it in the bearing member. Outwardly projecting pivot pins 23 and 24 are provided on end stoppers in tube 5 which engage with jewelled bearings. The tube 5 is provided at the middle of its length with an annular enlargement co-operating with the bore in the bearing member.
