Abstract:
1. A speaker array device comprising: a first speaker array configured to have plural first speaker units arranged in a first surface and output a first sound that is directed to a particular first direction from the plural first speaker units such that an angle of the first direction with respect to an arrangement direction of the plural first speaker units is adjustable; and a second speaker array configured to have plural second speaker units arranged in a second surface that is different from the first surface and output a second sound that is directed to a particular second direction from the plural second speaker units such that an angle of the second direction with respect to an arrangement direction of the plural second speaker units is adjustable, wherein when the second speaker array is installed together with the first speaker array in a room having a ceiling which functions as a sound reflection surface, 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 a direction in which the second sound reaches the sound receiving point such that a sound pressure ratio of a sound pressure of the second sound that reaches the sound receiving point after being reflected by the ceiling to a sound pressure of the second sound that reaches the sound receiving point directly is larger than or equal to a prescribed value, the sound receiving point being located in a normal direction to the first surface and being set as a position for listening to the first sound.
