The optical module includes a base, a first frame, an optical element and at least one driving assembly. The first frame is disposed in the base. The optical element is disposed in the first frame. The at least one driving assembly is disposed between the base and the first frame. The first frame is configured to move relative to the base by a magnetic force generated by the at least one driving assembly. Each of the at least one driving assembly includes a coil and a Halbach array magnet structure, the coil and the Halbach array magnet structure face each other along a first direction, a width of the Halbach array magnet structure in the first direction is W1, and a width of the coil in the first direction is W2, and 0.7≤W1/W2≤2."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical module and projection apparatus","description":"An optical module and a projection apparatus using the optical module are provided.
