MICROPHONE ARRAY APPARATUS HAVING HIDDEN MICROPHONE PLACEMENT AND ACOUSTIC SIGNAL PROCESSING APPARATUS INCLUDING THE MICROPHONE ARRAY APPARATUS

摘要

PURPOSE: A microphone array apparatus having a hidden microphone array structure and an acoustic signal processing apparatus including the same are provided to efficiently receive an acoustic signal by forming a microphone array including microphones. CONSTITUTION: A microphone array apparatus(100) includes a plurality of microphones(10,20,30,40). The microphones can be arranged in a linear or nonlinear structure. A cover(110) can have a hexahedron box shape. A unit(200) performing a specific function can be attached to a front side(111) of the cover. The interval between first type microphones covered with the cover can be narrowly arranged in comparison with the interval between second type microphones. The second type microphone is arranged in the inner groove region of a supporting plate(120).
