Patent ID: 6961438

Claim:
A loudspeaker system having wide-directional characteristics comprising: a loudspeaker body having a regular dodecahedron shape; twelve full range speakers, all having same frequency characteristics, disposed on outer peripheral surfaces of the loudspeaker body in a manner that axial lines of any adjacent two speakers intersect each other at a predetermined same angle, the twelve speakers being arranged either in a manner that said twelve speakers including three sets of speaker groups connected in parallel to each other, each speaker group including four speakers connected in series, or in a manner that said twelve speakers including four sets of speaker groups connected in series, each speaker group including three speakers connected in parallel to each other; and one correction filter operatively connected to the speakers and increasing sound pressures in relation to increasing sound frequencies to flatten the sound pressures at a position existing on a line extending straight from a center of the dodecahedron toward an outside of the dodecahedron via an apex position of the adjacent two speakers, wherein at the position an average attenuation in sound pressure versus the increasing sound frequencies from about 500 Hz and greater is maximum without the correction filter.
