## Abstract

Provided is a lens driving device includes a lens holder for carrying a lens; a frame for receiving the lens holder; a first driving component for driving the lens holder to move along a first direction in respect to the frame; a base moveably connected to the frame; a second driving component for driving the frame to move along a second direction in respect to the base, and a position sensor disposed on the frame for sensing a change in a position of the lens holder along the first direction in respect to the frame, wherein the first direction is not parallel to the second direction.

## Claims

### Claim 1

A lens driving device, comprising:
a lens holder for carrying a lens;
a frame for receiving the lens holder;
a first driving component for driving the lens holder to move along a first direction in respect to the frame;
a base moveably connected to the frame;
a second driving component for driving the frame to move along a second direction in respect to the base, and
a position sensor disposed on the frame for sensing a change in a position of the lens holder along the first direction in respect to the frame,
wherein the first direction is not parallel to the second direction, and the first direction is parallel to an optical axis of the lens.

### Claim 2 (depends on 1)

The lens driving device of claim 1, further comprising a circuit disposed on the frame and electrically connected to the position sensor.

### Claim 3 (depends on 2)

The lens driving device of claim 2, wherein the circuit comprises a 3-D circuit and the 3-D circuit is disposed on different surfaces.

### Claim 4 (depends on 2)

The lens driving device of claim 2, wherein the position sensor is electrically connected to the second driving component through the circuit, a first elastic body and a second elastic body.
