Abstract

615,423. Phonographic reproducers. SCHWARZ, H. F., and DECCA RECORD CO., Ltd. July 23, 1945, No. 18861. [Class 40 (iv)] In an electric pickup, the armature 16 extends into a gap between the unlike poles of two bar magnets 28 and is pivoted to vibrate about trunnions 11 with an axis to one side of and transverse to the common longitudinal axis of the magnets. The armature also lies within a coil 27 which is situated either in the gap between the magnets or to one side of the magnets. Either the stylus itself or the stylus holder may provide the armature. Suitable stylus holders are described in Specifications 615,421 and 615,422, and the mounting of the holder in rubber sleeves held in sockets in the body part 20 is described in Specification 615,424.
