PROBLEM TO BE SOLVED: To provide a head-set microphone-array audio input device capable of receiving a necessary signal with an excellent sensibility, even when the device has a superior mounting property and a peripheral environment is placed in an atmosphere having much noises. SOLUTION: The head-set microphone-array audio input device is composed of a head band, storage cases with ear pads fitted to both ends of the head band, respectively, and struts fitted to both storage cases with the ear pads, respectively. An arbitrary number of one or more of microphones are mounted on the struts, and output signals from the microphones can be output to the storage cases with the ear pads. COPYRIGHT: (C)2008,JPO&INPIT
