Abstract
A microphone array includes an n microphone units (where n is an integer equal to or larger than three). A first one of the microphone units includes three microphones ((-through-)) arranged in line at equal intervals. An m-th microphone unit (where m is a positive integer expressed by 1<m<n) includes the microphones at either end of an (m−1)-th microphone unit, and another microphone spaced from the microphone at one end of the (m−1)-th microphone unit by a distance substantially equal to the distance between the microphones at either end of the (m−1)-th microphone unit, and disposed at a location on the side of the (m−1)-th microphone unit opposite to the side where the microphone at the one end at the one end of the (m−1)-th microphone unit is disposed. The (m+1)-th microphone unit includes the microphones at either end of an m-th microphone unit, and another microphone spaced from the microphone at one end of the m-th microphone unit by a distance substantially equal to the distance between the microphones at either end of the m-th microphone unit, and disposed at a location on the side of the (m+1)-th microphone unit opposite to the side where the microphone at the one end of the (m+1)-th microphone unit is disposed.
