Abstract:
A speaker array device includes a first speaker array and a second speaker array. The first speaker array has plural first speaker units arranged in a first surface and output a first sound. The second speaker array has plural second speaker units arranged in a second surface that is different from the first surface and output a second sound. When the second speaker array and the first speaker array are installed in a room having a ceiling, the second speaker array is installed in such a manner that a normal direction to the second surface is match with a direction in which the second sound emitted from the second speaker array reaches, only indirectly, through reflection or diffraction, a sound receiving point or that the normal direction to the second surface is match with a direction in which the second sound reaches the sound receiving point with a predetermined sound volume.
