  • Patent number: 9736577
    Abstract: A speaker array apparatus includes an apparatus housing having a disposition plane, and a speaker array which includes a plurality of speakers disposed at least in a vertical direction on the disposition plane of the apparatus housing that is opposite to a listening position. The speaker array apparatus receives and distributes a sound signal input from an outside to all of or a part of the speakers of the speaker array, and outputs the distributed sound signal as a sound beam by controlling an output timing of each sound output from the all or part of the speakers. Each speaker of the speaker array has an appropriate output direction in an elevation angle, the appropriate output direction indicating a direction having largest sound pressure in a sound pressure distribution when the sound is output from the speaker.
