Abstract: Provided is an adjustable optical assembly (900), including a bearing base (921), a driving mechanism (910), a zoom optical assembly (200), and a compensating optical assembly (300). The driving mechanism (910) includes: a bracket (911) having a bottom end connected to the bearing base (921) and a top end having a top groove (911a) open upwards; guide rods (912, 913) supported on the top groove (911a), the guide rods (912, 913) coinciding with the direction of optical axes of the zoom optical assembly (200) and the compensating optical assembly (300); a zoom bearer (914); a compensating bearer (915); a zoom driving assembly; and a compensating driving assembly. The zoom bearer (914) and the compensating bearer (915) are both mounted on the guide rods (912, 913) and slidable along the guide rods (912, 913). Also provided are a corresponding periscopic optical zoom module and an assembly method therefor.

Abstract: The present disclosure provides a camera apparatus, an SMA driving device and a manufacturing method, a driving method and a wiring method, wherein the SMA driving device further comprises a lens carrier, at least one upgoing driver, and at least one downgoing driver; wherein the lens carrier is drivingly connected to the upgoing driver, and the upgoing driver supports the lens carrier upwardly in a thermally driven manner, and pulls the lens carrier to move upward; wherein the lens carrier is drivingly connected to the downgoing driver, and the downgoing driver draws the lens carrier downwardly in a thermally driven manner, and pulls the lens carrier to move downward; and wherein the lens is disposed on the lens carrier of the SMA driving device, and the SMA driving device drives the lens to move up and down, thereby improving the focusing speed of the lens.
