Abstract

1,205,610. Speech coils. OSAKA ONKYO K.K. 27 Dec., 1967 [24 Dec., 1966], No. 58726/67. Heading H4J. A speech coil for a loud-speaker or microphone has a conductive ribbon 111 extending helically along the length of a helically wound paper tape coil bobbin so that one end of the speech coil 95 may be attached thereto; in order that the external connections to the coil may be made at the other end of the bobbin. The bobbin is formed by inner and outer spirally wound paper tapes with the conductive ribbon fixed to the inner surface of the outer tape or the outer surface of the inner tape and the gap between adjacent turns of the ribbon filled by a paper tape.
