Abstract PROBLEM TO BE SOLVED: To provide a horizontal-plane omnidirectional small-sized speaker system whose occupation floor area for installation is small. SOLUTION: A plurality of speaker systems fitted with speakers on respective sides of prisms each having (n) sides are offset at an angle 180/n around a vertical center axis and stacked to obtain the horizontal-plane omnidirectional speaker system whose frequency components are well balanced at positions of the whole circumference of a horizontal plane, and the installation floor area of the horizontal-plane omnidirectional speaker system is reducible. In addition, cone type speakers are replaced with plane type speakers to make a speaker box small-sized and smaller in installation area. COPYRIGHT: (C)2006,JPO&NCIPI
