Abstract
448,653. Loud-speakers. SKINNER, G. D., and MAGNAVOX (GREAT BRITAIN), Ltd., Brantwood Works, Tariff Road, Tottenham, London. March 18, 1935, No. 8364. [Class 40 (iv)] [See also Group XL] Shielding or neutralizing means 8 is interposed between a cathode-ray tube 5 or other television reproducer and a coaxially or closely mounted reproducer of sound. A metallic pot surrounds the magnetic system of the loud-speaker, Fig. 1 (not shown), or a metallic sleeve 8 surrounds the sensitive portion of the cathode-ray tube. According to modifications, the sleeve may be replaced by a neutralizing coil, which is in the smoothing-circuit of the mains-current supply, Fig. 3 (not shown) ; a high-frequency moving-coil loud-speaker has a hollow centre, in which a cathode-ray tube is mounted with a surrounding horn and a constriction round the tube at the throat of the horn, Fig. 4 (not shown) ; an annular electrostatic loud-speaker is mounted in line with the viewing screen of the tube ; the sound and light are reflected from a common mirror. Specification 321,043, [Class 40 (iv)], is referred to.
