A cantilever microphone includes: a substrate; a cantilever including a rotor frame and a plate covering the rotor frame, where the cantilever includes a first edge fixed to the substrate and a second end opposite to the first edge, a plurality of rotor comb fingers is attached to the plate at an edge of the plate adjacent to the second edge; and a stator fixed to the substrate or attached to a sub structure to allow some displacement from the substrate, where the stator includes a plurality of stator comb fingers, and the stator comb fingers are interdigitated with the rotor comb fingers. For the cantilever microphone, high mechanical sensitivity of the cantilever and high electrostatic sensitivity of the comb structure can be implemented, so as to increase the performance or signal-to-noise ratio of the cantilever microphone.
