Abstract:
1. An audio reproduction apparatus comprising: an array speaker including a plurality of speaker units in a matrix or line arrangement; a directivity controller that controls directivity of an audio signal of each channel of input multi-channel audio signals in an independent direction of each other based on directivity control data set to each channel; a directivity control data storage device that stores the directivity control data for each channel for a basic pattern for controlling the directivity of each channel of the input multi-channel audio signals in separate directions, the basic pattern for multi-channel audio signals including at least one of: a pattern storage device that stores the basic pattern and a deformed pattern that assigns directivity control data for different channels to some or all of the channels of the input multi-channel audio signals using the directivity data for the basic pattern; a pattern selector that selects the basic pattern or the deformed pattern; and a controller that sets the directivity control data to the directivity controller based on the pattern selected by the pattern selector, wherein, when the pattern selector selects the deformed pattern, the controller sets the directivity of the audio signal of at least one of the channels using the directivity control data of the basic pattern of another of the channels that is different from the at least one one channel, wherein when the multi-channel audio signals are input in each of the channels, a sound directivity of sound output by the array speaker differs from a first case, where the directivity of the multi-channel audio signals is controlled based on the basic pattern, and a second case, where the directivity of the multi-channel audio signals is controlled based on the deformed pattern.
