Zusammenfassung:	PURPOSE:To enable a wiring from a microphone array to be handled without giving hindrance to a sound source search by passing the wiring from the microphone array provided opposite to a sound collector in a supporting frame. CONSTITUTION:A microphone array 2 wherein a number of microphones are arranged in matrix for forming a sound image is arranged opposite to the reflecting surface of a sound collector 1. The microphone array 2 is held by a supporting frame 10 provided with hollow pies and a wiring from the microphones in the microphone array 2 is passed in the hollow pipes. That is, the supporting frame 10 is provided with foot beams 10a composed of a plurality of the hollow pipes, the wiring is divided into a plurality of wires and wiring bundles are mounted on the sound collector 1 so as to be passed in the foot beams 10a. Thus, the wiring from the microphone array 2 provides no shielding in front of the sound collector 1 and the sound collecting effect of the sound collector 1 becomes good.
