Patent ID: 7519187

Claim:
An array speaker system comprising: an array speaker having a plurality of speaker units arranged in an array, including at least one center speaker unit and a plurality of peripheral speaker units, for emitting audio signal beams with predetermined time differences therebetween so as to control sound directivity; and a control circuit that imparts a first weight to the center speaker unit with respect to high-frequency signal components of input audio signals, and second weights to the peripheral speaker units in the array speaker with respect to the high-frequency signal components of the input audio signals, wherein the first weight is relatively higher than the second weights, wherein the control circuit imparts a third weight to the center speaker unit with respect to low-frequency signal components of the input audio signals, and imparts fourth weights to the peripheral speaker units with respect to the low-frequency signal components of the input audio signals, and wherein differences between the third and fourth weights, which are imparted to the center speaker unit and the peripheral speaker units with respect to the low-frequency signal components, are relatively smaller than the differences between the first and second weights, which are imparted to the center speaker unit and the peripheral speaker units with respect to the high-frequency signal components.
