Abstract
The present disclosure relates to a microphone, and more particularly, to a microphone capable of improving a signal-to-noise ratio (SNR) by receiving a sound pressure through at least two acoustic sensing modules. According to an exemplary form of the present disclosure, a microphone includes first and second acoustic sensing modules including a diaphragm vibrated by a sound pressure introduced from the outside and a fixed membrane spaced apart from the diaphragm, and a signal processing module receiving first and second capacitance signals from each of the first and second acoustic sensing modules and removing and outputting noises included in the first and second capacitance signals based on the first and second capacitance signals.
