Provided are a micro-projection device, a magnetic suspension base, and a micro-projection equipment. The micro-projection device includes a micro-projector and a main suspension magnet. The micro-projector is fixed to the main suspension magnet. As a magnetic field direction at the magnetic field center of the main suspension magnet is in the vertical direction, so the micro-projector is able to be suspended in a magnetic field environment. The magnetic suspension base includes a housing and at least three base magnets placed in the housing. The magnetic field direction at the center of the combined magnetic field, formed by the at least three base magnets, is in the vertical direction; the intensity of magnetism at the center of the combined magnetic field is less than the intensity of magnetism around the base magnets; and the micro-projector is fixed to the magnets to be able to be suspended in the magnetic field environment. |
