Abstract
A moving mechanism for holding a lens is provided, including a carrier having an accommodating space, a coil, a sensing object, a base, at least one magnetic member, and a position detector, wherein the lens is disposed in the accommodating space. The coil and the sensing object are disposed on the carrier, and the coil surrounds the accommodating space. At least a portion of the coil is disposed between the sensing object and the accommodating space. The magnetic member and the position detector are disposed on the base, and the position detector is adjacent to the sensing object. When a current flows through the coil, the carrier moves relative to the base.
Claims20
An optical member driving module, comprising:
- a base;
- a carrier, for holding an optical member having an optical axis;
- a driving assembly, driving the carrier to move relative to the base;
- and
- a position assembly, sensing the relative movement between the carrier and the base, wherein the driving assembly comprises a magnetic member having a longitudinal axis, and the carrier and the position assembly are overlapped as seen from a direction perpendicular to the optical axis and the longitudinal axis.
An optical member driving module, comprising:
- a base;
- a carrier, configured to hold an optical member having an optical axis, wherein the carrier is movable relative to the base;
- a driving assembly, configured to drive the carrier to move relative to the base;
- a sensing object, disposed on the carrier;
- and
- a position detector, disposed on the base and configured to sense the sensing object to detect the relative movement between the carrier and the base.
