Abstract
An apparatus for generating directional sound is provided. By using a time-variant beam pattern, the apparatus may generate constant direct waves in a listening area and may vary reflected waves followed by the direct waves according to time. The apparatus may convolute the time-variant beam pattern with a sound signal, may process an acoustic signal, which may be obtained through convolution, into a multi-channel signal, and may amplify and output the multi-channel signal.
