Abstract: This application discloses a magnesium alloy connection mechanical part, an electronic device, and a component forming method. A magnesium alloy body and a conducting layer, and a transition layer that can conduct electricity is formed in a region in which the magnesium alloy body is connected to the conducting layer, and an electrical connection between the magnesium alloy body and the conducting layer is implemented by using the transition layer. The magnesium alloy body and the conducting layer are separated by using the transition layer. In addition, the magnesium alloy body is isolated from the outside by using the conducting layer, a sealing material, and the transition layer, to avoid oxidation or corrosion of the magnesium alloy body, and further avoid galvanic corrosion between structures in the magnesium alloy connection mechanical part.

Abstract: This application provides a camera module and an electronic device, to reduce manufacturing costs of the camera module and improve reliability of the camera module on the premise of ensuring optical image stabilization and auto-focus functions. The camera module includes a housing, and a light transfer part, a lens group, an image sensor, and a motor disposed in the housing. The image sensor is located on the side of the light output side. The motor includes a bracket, a carrier, and eight wires. Two ends of the wires are respectively connected to the carrier and the bracket, and the wires are retractable in length. The carrier is suspended from the bracket using the eight wires and is configured to carry the lens group, and, when the wires extend or retracts in length, drive the lens group to translate or rotate.

Abstract: A camera, camera lens, image sensor, and a shape memory alloy (SMA) motor are stacked within a frame. The SMA motor is located on an out-light side of the camera lens. The image sensor is located between the lens and the SMA motor and is fastened to the SMA motor. The SMA motor is configured to actuate the image sensor to shift on a plane perpendicular to an optical axis of the camera lens. The camera may be associated with an electronic device.
