Speaker Array Apparatus

摘要

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.

主权项

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 configured to be 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, wherein when the second speaker is installed together with the first speaker array in a room having a ceiling which functions as a sound reflection surface, the second speaker 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 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.
