Abstract

301,158. Andrewes, H., and Dubilier Condenser Co. (1925), Ltd. Oct. o, 1927. Addition to 285,315. Electric sound-boxes.- An electrostatic soundreproducer of the kind claimed in the parent Specification is provided with means for damping tlie vibrations of the stylus-bar and diaphragm, and for adjusting the air-gap between the diaphragm and the fixed electrode. As shown, a bridge 11 is attached diametricadly to the front of the casing 3 of the reproducer, and has adjustably mounted thereon, by means of a screw and nut 13, 14, a buffer 12 bearing against the stylusbar 6.
