Summary:To provide a microphone capable of setting a correction value without need for a sound source.SOLUTION: A microphone includes a MEMS device 200, a driver 330 and a control section 320. The MEMS device outputs a first electric signal corresponding to an acoustic pressure. The driver vibrates the MEMS device through a driving signal. The control section computes a correction value for correcting the first electric signal on the basis of a second electric signal output from the MEMS device when being vibrated by the driving signal.SELECTED DRAWING: Figure 6 【課題】音源がなくとも補正値を設定することのできるマイクロフォンを提供する。【解決手段】マイクロフォンは、ＭＥＭＳデバイス２００と、ドライバ３３０と、制御部３２０と、を有する。ＭＥＭＳデバイスは音響圧力に応じた第１電気信号を出力する。ドライバは駆動信号によってＭＥＭＳデバイスを振動させる。制御部は、駆動信号によって振動させられている際にＭＥＭＳデバイスから出力される第２電気信号に基づいて、第１電気信号を補正するための補正値を算出する。【選択図】図６
