Abstract

847,144. Loud-speakers. KOHLER, H. H. J. Dec. 2, 1957, No. 37513/57. Class 40 (4). [Also in Group XXXVIII] A dome-shaped reflector 2 is mounted on a rectangular plate 1 behind the diaphragm 7 of a loud-speaker. The loud-speaker itself is mounted on a baffle-board 6 carried by the plate 1. Flaps 4, hinged to the edges of the plate 7 deflect the sound from the rear of the diaphragm in a forward direction. The magnet of the loud-speaker falls within an aperture at the top of the reflector 2.
