PROBLEM TO BE SOLVED: To provide an audio input device and an audio input method that suppress variation in sound quality caused when a noise sound is removed as much as possible. SOLUTION: The audio input device includes an audio input means of inputting audio, and a plurality of devices A, B, and C which are driven at predetermined driving frequencies respectively to generate noise sounds based upon the driving frequencies. The audio input means has a noise sound removing means of removing noise sounds, and one of the devices A, B, and C is driven having its driving frequency equalized to a driving frequency of another device or an integral multiple thereof. The noise sound removing means removes noise sounds generated based upon the driving frequencies of the devices A, B, and C. COPYRIGHT: (C)2007,JPO&INPIT
