The application discloses a laser scanning device and electronic equipment, which comprises a fiber actuator, a lens and a galvanometer assembly. The fiber actuator is connected with an optical fiber and drives the optical fiber to vibrate and scan on a first plane at a first working frequency under the drive of an external driving signal, and an external laser beam is emitted into the lens through the optical fiber. The galvanometer assembly is provided with a reflecting mirror, which has a first inclination angle and can rotate and vibrate around an axis parallel to the first plane at a second working frequency under the drive of an external driving signal, so as to project and reflect the light emitted from the lens to a preset area and form an image.
