Abstract: A speaker apparatus includes an input portion to which audio signals of a plurality of channels are input, a plurality of speakers, a directivity controlling portion that delays the audio signals of the plurality of channels input to the input portion and distributes the delayed audio signals to the plurality of speakers so that the plurality of speakers output a plurality of sound beams, and a localization adding portion that applies a filtering processing based on a head-related transfer function to at least one of the audio signals of the plurality of channels input to the input portion and inputs the processed audio signal to the plurality of speakers.

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.

Abstract: A speaker array apparatus includes a speaker array, a beam forming portion that is configured to cause the speaker array to output the sound beam, a beam control portion that is configured to sweep with the test sound beam in a predetermined angle range in a vertical direction with respect to a horizontal direction, a microphone, a distance obtaining portion that is configured to obtain a distance between the speaker array and the microphone, and a storage portion that is configured to store pickup sound data that is associated with the output angle. The beam control portion sets a minimum output angle of the angle range to be larger as the distance obtained by the distance obtaining portion is smaller.

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.
