Abstract
Provided are apparatus and method for focusing sound so that a sound radiation pattern output from an array speaker system composed of a plurality of speakers may approach a target sound radiation pattern. The sound focusing apparatus uses a focusing filter formed in consideration of sound characteristics of the array speaker system. In addition, the sound focusing apparatus may compensate for delay and gain values of each channel generated when an input signal is replicated to a plurality of channels and output through an array speaker in the array speaker system.
