Abstract: A microphone module according to the present disclosure includes a housing, a vibration sensor, and a subtractor. The vibration sensor outputs electric signals. The electric signals each represent collected sound and vibration. The subtractor outputs a subtraction signal on the basis of differential signals. The differential signals correspond to an output difference between the electric signals output by the vibration sensor.
