Abstract
313,904. Neale, J. March 19, 1928. Phonographic reproducers; transmitters inwhich a sound-controlled lightbeam acts on a photo-electric element. - In the reproduction of sound from a, gramophone record by causing a stylus to vibrate a diaphragm which reflects a beam of light on to a, light-sensitive device in circuit with a loud speaker, the rejecting diaphragm is not mounted on the record traversing arm and is vibrated from the stylus through non- rigid mechanical means. As shown, the stylus 3 transmits its vibrations to the diaphragm 4 through a Bowden wire mechanism comprising a wire 6 within a casing 7. The, diaphragm 4 is mounted in a stationary casing 5 and reflects a beam on to a cell 13 in circuit with a loud speaker 14. Specification 314,126 is referred to.
