Abstract: An electrostatic MEMS micromirror is provided, and may be used in a device such as a mobile phone, a microphone, a camera, a radar, or an optical switch. The electrostatic MEMS micromirror includes a support beam, a micromirror, and a drive component. The drive component includes a comb frame and a drive comb located in the comb frame. The support beam and the micromirror are mechanically coupled using the comb frame. Two sides of the comb frame that are mechanically coupled to the micromirror are separately located on two sides of a rotating axis determined by the support beam. The drive comb includes at least one comb pair. The comb pair includes a movable comb structure and a stationary comb structure. The movable comb structure includes a plurality of movable combs. One end of the movable comb is fastened to the comb frame.
