| 摘要 | An audio processing device including a first audio collecting unit configured to convert an audio vibration into an electric signal and acquire an audio signal includes a shielding unit having a predetermined resonant frequency that shields the first audio collecting unit from an influence of airflow outside the device; and an acquiring unit configured to acquire, as a first audio signal, an audio signal in a predetermined frequency band lower than the resonant frequency of the shielding unit from among the audio signal acquired by the first audio collecting unit that is shielded from the influence of the air flow outside the device by the shielding unit. | ||
