Abstract

227,391. Sykes, A. r. July 3, 1923. Addition to 160,223. Electric and magnetic sound-boxes; soundboxes, arranging and supporting.-In sound-reproducing apparatus of the kind claimed in the parent Specification, a sound record is reproduced by means of a non-resonant electrodynamic generator actuated directly by a stylus attached to the armature of the generator, thereby deriving an electric potential which is the differential of the wave form of the vibration of the stylus. The potentials so obtained may operate valve circuits, of which the output frequency characteristic is under control, for working a loud-speaker. The generator may consist of a reed type telephone receiver, suitably modified as shown for example in Figs. I and II. The armature is a reed 120, provided with a fin 121 which carries the diamond or sapphire for engaging the record, the reed being mounted on a torsional elastic pivot 289. As described in Specification 190,759, the interior of the shell of the reproducer may be filled with grease or petroleum jelly. The reproducer is supported in a ring 288, swivelled on a bracket 284 which is secured to a standard 285, the record cylinder being fed under the reproducing-point. Figs. III and .IV show a generator of the moving-coil type. An E- shaped permanent magnet 7 has polar extensions 9 between which is located a stiff armature-coil 1 carrying a stylus 3 (or two styli, as shown, for use optionally with lateral-cut or hill-and-dale records). The coil is adapted to vibrate about an axis determined by a stiff spring 281, and may consist of a large number of turns of insulated wire. Wooden blocks are inserted in the coil at either end, the central pole of the magnet being surrounded by the coil. Specifications 126,970, 145,805, 186,658 and 190,840, [both in Class 40 (iv), Telephones &c.], 194,424, 195,879, 210,956; 222,413, [Class 40 (iv), Telephones &c.], and 222,924 also are referred to.
