Abstract

615,481. Supporting loud-speakers. PHILIPS LAMPS, Ltd. May 31, 1946, No. 16547. Convention date, March 18, 1942. Drawings to Specification.- [Class 40 (iv)] [Also in Group XL (c)] Electrical apparatus for stereophonic sound reproduction comprises at least two separate channels each with at least one associated loud-speaker so that the sound separately transmitted over each individual channel is reproduced by the corresponding loud-speaker or loud-speakers, a cabinet containing the electrical parts of the apparatus, and at least two laterally-adjustable loud-speakers constructionally integral with the cabinet and each communicating with one of the separate channels of the electrical apparatus. These loud-speakers, which may be manually moved so that their distance apart exceeds the largest dimension of the cabinet, are adjustable to produce optimum reproducing conditions. If desired, the low-frequency band may be reproduced solely by a separate stationary loudspeaker housed in the cabinet.
