Abstract

1276013 Moving coil instruments TSAGAWA 2 June 1969 [3 June 1968] 27731/69 Heading H4J The voice coil of a device for radiating sound from a wall or other vibratory panel is formed by winding around a cylindrical former 2 a conductor (e.g. copper or aluminium) having an intermediate layer of magnetic material such as iron or nickel and an outer coating of insulating material such as synthetic resin. The coil former 2 is joined at one end to a non-ferrous metal diaphragm 6 having air holes 6a, the former 2 being adhered to the diaphragm 6 at an annular groove 6b. The diaphragm 6 is secured at its periphery to a yoke 3 of the magnetic system and has a mounting means such as a screw, needle or projection by which the device, in use, is secured to a sounding board D, which may be a desk surface, wall panel, ceiling board or one side of a radio case.
