Abstract

313,713. Aspden, R. L. May 1, 1928. Gramophone pickups.-A combined mechanical soundbox and electric pick-up comprises a stylus bar connected to a large diaphragm directly emitting sound without an associated horn and also serving as a damping device for the pick-up which comprises electromagnets influenced by the vibrating stylus bar or a projection therefrom. Fig. 1 shows a large diaphragm a mounted in a frame or spider b supported to swing over a record and connected eccentrically to a stylus arm c whose vibrations influence electromagnets d, e supported from the frame b.
