The lens driving device includes a case having an accommodation space, in which a lens module is provided. The lens module includes a lens, a lens holder receiving the lens, a support frame for freely rotating the lens holder in a direction orthogonal to an optical axis direction, support members, an electromagnetic driving device, and a base for fixing a circuit board; the electromagnetic driving device is arranged on the lens holder and the base for fixing the circuit board, and is provided adjacent to a level of a center of gravity of the lens module; and the lens module have different movement axes in a plane and is rotatable freely relative to the base for fixing the circuit board.

Lens driving device for camera, camera and electronic apparatus

The present invention provides a lens driving device, a camera, and an electronic apparatus with a small size, a large correction angle and an excellent hand vibration correction effect. The lens driving device includes a case having an accommodation space, which accommodates a lens module; support frames, support members, and an electromagnetic driving device, for freely rotating the lens module in a direction orthogonal to an optical axis direction; and a base for fixing a circuit board; the electromagnetic driving device is arranged at the support frames and at the base for fixing the circuit board, and is arranged adjacent to a level of a center of gravity of the lens module; and the support frames includes a first support frame and a second support frame, each of the first support frame and the second support frame has different movement axes in a plane and is rotatable freely relative to the base for fixing the circuit board.

The present disclosure provides a small and well-focused lens driving device, a camera including the lens driving device, and a portable electronic apparatus. The lens driving device includes a fixing base, a cover, a lens holder, a support frame, a support member, and a shape memory alloy portion. In the lens driving device, a receiving space is defined by the fixing base and the cover. The lens holder configured to receive a lens, as well as the support frame, the support member, and the shape memory alloy portion that cause the lens holder to move freely in an optical axis direction are provided in the receiving space. The shape memory alloy portion has a shape memory alloy and a crimping lug, and the shape memory alloy portion is provided on the fixing base and the support frame to cause the lens holder to move freely in the optical axis direction.

Lens driving device, camera and portable electronic apparatus

Provided is a lens driver movable in a direction parallel to an optical axis, arranged on a lens driver movable in a plane orthogonal to the optical axis, and accommodated in a casing. The lens driver includes: a fixture base, a support frame A, a lens module, a spring piece, a first driving coil, a magnet and a yoke. The lens driver includes: a base; a connection terminal and a conductive member A arranged on the base; a support frame B supported by a support part; a conductive member B arranged on the support frame; a center holding part for keeping the base and the support frame B at a center of the optical axis; a second driving coil arranged on the base; and a magnetic detecting element. The lens driver provided can achieve purposes of anti-image dithering and simplifying assembly to obtain good image quality.
