APPARATUS AND METHOD FOR CONTROLLING ACOUSTIC RADIATION PATTERN OUTPUT THROUGH ARRAY OF SPEAKERS |
摘要 |
Provided are an apparatus and method for controlling an acoustic radiation pattern output through an array of speakers. The apparatus stores a plurality of filter values for forming a plurality of corresponding control patterns set in advance from an input signal. The apparatus forms a compensation control pattern such that signals output through the array of speakers have an intended pattern in consideration of a filter value of a focusing filter. The apparatus selects at least one of the control patterns set in advance to form the compensation control pattern, and processes the input signal using a filter value corresponding to the selected control pattern.
