Abstract

287,954. Wheeler, P. J. C. Dec. 21, 1926. No Patent granted (Sealing fee not paid). Magnetic instruments.-An electromagnetic device for reproducing recorded sound comprises a permanent magnet having an upper limb 10 and a lower limb 11 joined by a magnetic yoke 12, a non-magnetic distance-piece 13 being provided. A coil 14 adapted to be vibrated by a stylus 15 encircles the limb 11. The coil is mounted on the needle-socket 20, which is pivoted on the free end of a light plate 22, itself pivoted between lugs 23 on the limb 11 of the magnet. The coil and needle-socket may be unconstrained, or may be lightly damped so as to be aperiodic.
