PROBLEM TO BE SOLVED: To provide a novel speaker system for generating a local sound field.SOLUTION: A speaker system having a speaker array in which plural sub speakers are dispersively arranged on an array face contains a signal processor inherent to each sub speaker, a signal distributor for outputting an input audio signal to each signal processor, and a main sound volume setting part for setting a main sound volume in each signal processor. Each signal processor contains a signal amplifier for amplifying an audio signal input from the signal distributor at the amplification factor corresponding to a sub sound volume obtained by multiplying the set main sound volume by a predetermined sound volume weighting coefficient, and a phase corrector for executing correction for delaying the phase of the audio signal amplified in the signal amplifier by 180 degrees as occasion demands.SELECTED DRAWING: Figure 10 |
