    摘要： An optical element driving mechanism is provided. The optical element driving mechanism is disposed on an electronic apparatus. The optical element driving mechanism includes a first movable portion, a fixed portion, a first driving assembly, a circuit assembly, and a first position sensing assembly. The first movable portion is used for connecting to a first optical element. The first optical element is used for corresponding to light. The first movable portion is movable relative to the fixed portion. The first driving assembly is used for driving the first movable portion to move relative to the fixed portion. The circuit assembly is used for electrically connected to the electronic apparatus. The first position sensing assembly is used for detecting the movement of the first movable portion relative to the fixed portion.

    摘要： An optical system includes a fixed module, a movable module and a driving assembly. The movable module moves relative to the fixed module, and the movable module includes a lens unit which includes a first lens, a second lens, a first side wall and a second side wall. The first side wall has a first surface, which directly contacts the second lens, and the second side wall directly contacts the first lens. A portion of the driving assembly is directly disposed on the lens unit, configured to drive the lens unit to move along an optical axis of the first lens. The first side wall further has a second surface opposite to the first surface, and the second surface directly contacts the portion of the driving assembly. The thickness of the first side wall is different from the thickness of the second side wall.

    摘要： An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed part, a movable part, and a driving assembly. The fixed part includes a bottom. The movable part moves relative to the fixed part and holds an optical element with an optical axis. The driving assembly drives the movable part to move relative to the fixed part. The bottom includes a base and an embedded assembly. A portion of the embedded assembly is embedded in the base. The embedded assembly includes a circuit member and a strengthening frame with a plate structure. The strengthening frame includes a perforation. The optical axis passes through the perforation.
