In an array speaker device, a plurality of speaker units output sounds having directivities, which are then reflected on a prescribed wall or a reflection board so as to form virtual speakers, wherein a digital signal processor independently drives the plurality of speaker units in such a way that sound beams produced in response to input audio signals are emitted toward prescribed focal point positions in the space. A CPU sets up the focal point positions, which normally vibrate as necessary. Thus, a broad listening range and sound localization are realized.
