Abstract
830,117. Telephone instruments. STANDARD TELEPHONES & CABLES Ltd. July 4, 1958, No. 21473/58. Class 40 (4). In a moving-coil transducer, the terminations 3 and 4 of the moving coil 2 and the periphery of the diaphragm 1 are embedded in a moulded insulating ring 7. The ring 7 carries terminals 5 and-6, to which the wires 3 and 4 are soldered, and spigots 8 for locating the diaphragm-andcoil assembly on the magnet unit.
