Abstract
A two-dimensional scanning and reflecting device includes a vibration component and a scanning component. The vibration component has a free end. The scanning component includes a frame body, a mass block, and a mirror. The frame body is connected to the free end of the vibration component. A natural frequency of the mirror corresponds to a second frequency. The mass block is disposed on the frame body in an eccentric manner, and the mass block and the natural frequency of the mirror correspond to a first frequency. When the vibration component receives a multi-frequency signal having the first frequency and the second frequency, the mirror vibrates in an axial direction with the first frequency, and vibrates in another axial direction with the second frequency.
