Abstract:
1. An optical device, comprising: a drive moving assembly comprising a lens module and a drive coil, wherein the lens module provides an optical axis, and the drive coil surrounds the lens module and provides a central axis parallel to the optical axis; a drive stator, comprising: a brake coil disposed in the opening of the magnetic member of the drive stator and providing a central axis perpendicular to the optical axis of the lens module of the drive moving assembly, wherein the brake coil opposes the drive coil of the drive moving assembly; and a braking resilient member connected between the drive stator and the brake coil and disposed in the opening of the magnetic member of the drive stator, wherein the brake coil interacts with the magnetic member and the yoke of the drive stator, and the braking resilient member and detachably abuts the drive moving assembly.
