<p>An array speaker device includes a plurality of speaker units from which audio is outputted and reflected with directivity against a predetermined wall surface or a reflection plate so as to form a virtual speaker. Each of the plurality of speaker units is independently driven so that an audio beam generated according to the input audio signal by a digital signal processor is emitted to a predetermined focal point position in a space. Moreover, the focal point position is set by a CPU and the focal point position is vibrated as is required. This enables realization of a wide listening range and a sound image positioning.</p>
