Abstract: A lens device comprises a connect assembly, a lens assembly and a drive assembly. The lens assembly is disposed on the connect assembly and has a central axis. The drive assembly comprises a first coil, a magnet and a second coil. The first coil is wound around the lens assembly. The magnet is disposed on the connect assembly and has a first magnetic pole, a second magnetic pole, a first direction of magnetic field and a second direction of magnetic field. The first direction of magnetic field and the second direction of magnetic field are not parallel to each other. The first direction of magnetic field points toward the first coil. The second coil is disposed on the connect assembly. The second direction of magnetic field points toward a part of the second coil.

Abstract: An ultrasonic linear actuation device includes a mover and a plurality of stator sets. The mover includes at least one mover rack. The plurality of stator sets is located in correspondence with the mover. Each of the plurality of stator sets includes an actuating component and a plurality of stator racks. The actuating component is used for stimulating corresponding one of the plurality of stator sets to generate standing-wave oscillations in an oscillation direction, such that the plurality of stator racks of each of the plurality of stator sets can engage the at least one mover rack of the mover to allow the stator racks to mesh the corresponding mover rack and thus to displace the mover in a moving direction.
