Abstract: An optical module is provided. The optical module includes a first optical element driving mechanism. The first optical element driving mechanism includes a first movable portion, a first fixed portion, and a first driving assembly. The first movable portion connects an optical path adjustment element. The optical path adjustment element is configured to change a transmission direction of incident light to a first direction that is different from the transmission direction. The first fixed potion is polygonal when viewed in the transmission direction. The first movable portion is movable relative to the first fixed portion. The first driving assembly drives the first movable portion to move relative to the first fixed portion. The first driving assembly comprises a shape memory alloy. The first driving assembly is located on a first side of the first fixed portion when viewed in the transmission direction.

Abstract: A feedback system is provided. The feedback system includes a main body, a vibration module, a sensing module, and a control module. The vibration module includes a first vibration mechanism. The first vibration mechanism is used for providing a first vibration force to the main body at a first vibration position. The sensing module is used for detecting the status of the main body and providing a sensing signal. The control module is used for receiving the sensing signal and providing a driving signal to the first vibration mechanism to generate the first vibration force.

Abstract: An optical element driving mechanism includes a fixed portion, a movable portion, a moving portion, a first driving assembly and a second driving assembly. The movable portion is movable relative to the fixed portion. The moving portion is connected to an optical element having an optical axis, and is movable relative to the movable portion. The first driving assembly drives the movable portion to move relative to the fixed portion; and the second driving assembly drives the moving portion to move relative to the movable portion.

Abstract: An electromagnetic driving module is provided, including a first member, a second member movably connected to the first member, an electromagnetic driving assembly, and a film. The electromagnetic driving assembly includes a magnet and a coil respectively disposed on the first and second members, so as to move the second member relative to the first member. The film is disposed on a side of the magnet to reduce magnetic interference between the magnet and a magnetic element, wherein the magnetic permeability of the film is higher than the magnetic permeability of the first member.
