    Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a movable part and a fixed part. The movable part holds an optical element with an optical axis and moves relative to the fixed part. The fixed part includes a bottom unit, which is integrally formed. The bottom unit includes a base member, a circuit member, and a driving coil assembly. The driving coil assembly is electrically connected to the circuit member. The circuit member and the driving coil assembly are located at the base member. The driving coil assembly includes a connection wire, a plurality of first driving coils, and a plurality of second driving coils. The first driving coils are connected via the connection wire. The second driving coils are located between the first driving coils and the circuit member. When viewed along a direction that is perpendicular to the optical axis, the second driving coils partially overlap the connection wire.

    Abstract: An electromagnetic driving mechanism is provided for driving two different optical lenses, including a base, a first holder, a frame, a resilient element, a first electromagnetic driving assembly, a second holder, and a second electromagnetic driving assembly. The first and second holders are provided for holding the optical lenses. The frame is affixed to the base, has magnetically permeable material, and surrounds the first holder. The resilient element connects the first holder with the frame. The first electromagnetic driving assembly is disposed between the first holder and the frame to drive the first holder moving relative to the base. The second electromagnetic driving assembly is disposed on an outer side of the second holder to drive the second holder moving relative to the base.

    Abstract: An optical system includes a base, a first lens driving module, and a second lens driving module. The first lens driving module includes a first lens holder, a first magnet, and a first coil. The first lens holder is configured to hold a first optical element. The first coil corresponding to the first magnet is configured to drive the first lens holder to move relative to the base. The second lens driving module includes a second lens holder, a second magnet, and a second coil. The second lens holder is configured to hold a second optical element. The second coil corresponding to the second magnet is configured to drive the second lens holder to move relative to the base. The first magnet is disposed between the first and second lens holders, and no other magnet is disposed between the first and second lens holders except the first magnet.

    Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed part, a movable part, a first driving assembly, and a strengthening member. The fixed part includes a first base. The movable part is connected to an optical element with an optical axis. The movable part is movable relative to the fixed part, and the movable part is accommodated in the fixed part. The first driving assembly drives the movable part to move relative to the fixed part. The first driving assembly is disposed in the first base. The strengthening member is embedded in the first base. When viewed along a direction that is perpendicular to the optical axis, the strengthening member at least partially overlaps the first driving assembly. When viewed along the optical axis, the strengthening member does not overlap the first driving assembly.
