UNDIRENTIONAL SPEAKER SYSTEM FOR SPEAKER CABINET APPARATUS

摘要

PURPOSE: A speaker cabinet for non-directional speaker system is provided to generate sound wave uniform across 360° by installing reflector plates and suitable size of openings. CONSTITUTION: Two hemispherical cabinets are detachably coupled to define a global speaker cabinet(70). The speaker cabinet(70) has fixing parts(73) in the upper and lower parts of the speaker cabinet to fix speaker units(71). The speaker cabinet(70) surrounds the speaker units(71). Sound reflector plates(72) are installed in front of the speaker units(71) to diffuse sound wave. Suitable size of openings(74) are installed across the speaker cabinet(70) to diffuse indirect sound components of sound from the speaker unit(71). Sound from the speaker units(71) is diffused by the reflector plates(72) to obtain stereophonic non-directionality. The reflector plates(72) are convex into the cabinet(70). Fixing ribs(75) are installed in the speaker cabinet(70) to couple the two hemispherical cabinets.
