Abstract
An optical device. A drive moving assembly includes a lens module and a drive coil. The drive coil surrounds the lens module and provides a central axis parallel to an optical axis of the lens module. A drive stator includes a housing, a magnetic member, and a yoke. The lens module is movably disposed in the housing. The magnetic member surrounds the drive coil and includes an opening. The yoke interacts with the magnetic member, generating a magnetic field. The magnetic member, yoke, and drive coil interact to move the drive moving assembly parallel to the optical axis. A brake coil is disposed in the opening. A braking resilient member is connected between the drive stator and the brake coil and disposed in the opening. The brake coil interacts with the magnetic member, yoke, and braking resilient member and detachably abuts the drive moving assembly.
