Abstract

257,983. Gariazzo, P. A. June 4, 1925. Diaphragms.-A large diaphragm sound reproducer adapted to play zig-zag or hill-and-dale records has a diaphragm made from a thin film of material, such as cellon, in the form of a cone with incurved side which is mounted in a frame fitted with a ring bearing on the diaphragm for damping purposes and is adjustably supported for tilting and swinging about a vertical axis. The film diaphragm 15 is clamped between the down-turned flanges of a conical cage 21 of metal. celluloid &c., and a ring 3 between which is also held an annular plate 17 supporting an upstanding ring 19, or a ring of india rubber tubing, bearing against the diaphragm to damp it and prevent vibrations passing to the portion outside of the damping ring.
