Abstract
An optical module including a transparent component and at least one coil device is provided. The at least one coil device is connected to the transparent component and includes a main body and at least one extending wire. The at least one extending wire is extended out from the main body, the at least one coil device is adapted to be driven by a magnetic force to vibrate along at least one rotation axis, and a length of the at least one extending wire is in positive correlation with a width of the transparent component along a direction. The direction is perpendicular to the at least one rotation axis and perpendicular to an optical axis of the transparent component. In addition, a projector having the optical module is also provided.
