Abstract
873,512. Loud-speakers. BOSE, A. G. July 30, 1957 [Aug. 6, 1956], No. 12711/61. Divided out of 873,511. Drawings to Specification. Class 40 (4). A baffle having a non-spherical surface with edges which fit along three mutually perpendicular surfaces, such as the corner of a room, has loud-speaker diaphragms fitted over apertures in the baffle so as to cover more than half its surface. Specification 873,513 also is referred to.
