Abstract

964,555. Loud-speakers. S. R. RICH. June 6, 1962 [June 14, 1961], No. 21941/62. Heading H4J. A loud-speaker, particularly for reproducing the higher audiofrequencies, comprises a pair of permanent bar magnets 11, 12 having poles on opposite long faces and having like poles confronting each other, with steel and plates 14, 15 and a spacer bar 13 supporting a diaphragm 26 of corrugated aluminium foil, and a voice coil 17 in the form of a flat spiral fixed to a platform 16 on top of the magnets, so that the voice currents induce eddy currents in the diaphragm. The loud-speaker may be provided with a wooden frame for convenient mounting in a casing. U.S.A. Specifications 1,577,254 and 1,643,791 are referred to.
