## Abstract

Actuators for actuating a lens in a folded camera, folded cameras including such actuators and dual-cameras including such folded cameras. The actuators actuate a lens having a lens optical axis for auto-focus (AF) and optical image stabilization (OIS) and comprise a stationary sub-assembly that includes an OIS coil having an OIS coil plane and an AF coil having an AF coil plane, and a lens actuating sub-assembly movable relative to the stationary sub-assembly with a lens holder holding the lens, wherein the OIS coil plane is perpendicular to the AF coil plane and wherein the lens optical axis lies between the OIS coil plane and the AF coil plane. Some actuators have a design using VCM actuation and a reduced height due to top and/or bottom openings in actuator envelopes.

## Claims

### Claim 1

An actuator suitable to be used in a folded camera and configured to actuate a lens having a lens optical axis for auto-focus (AF) and optical image stabilization (OIS), the actuator comprising:
a) a stationary sub-assembly that includes an OIS coil having an OIS coil plane and an AF coil having an AF coil plane; and
b) a lens actuating sub-assembly movable relative to the stationary sub-assembly and including a lens holder holding the lens,
wherein the OIS coil plane is perpendicular to AF coil plane and wherein the lens optical axis lies between the OIS coil plane and the AF coil plane, and
wherein the OIS coil and the AF coil are on opposite sides of a plane defined by the lens optical axis and an entrance optical axis in the folded camera.

### Claim 2 (depends on 1)

The actuator of claim 1, wherein the stationary sub-assembly further includes a plurality of upper stepping yokes, wherein the lens actuating sub-assembly further includes a plurality of stepping magnets coupled to the plurality of upper stepping yokes, and wherein the plurality of stepping yokes and the plurality of stepping magnets are operable to create stepping forces in a direction perpendicular to the lens optical axis for stepping.

### Claim 3 (depends on 2)

The actuator of claim 2, wherein the stationary sub-assembly further includes an OIS Hall sensor bar used in conjunction with one of the stepping magnets to perform position sensing.

### Claim 4 (depends on 2)

The actuator of claim 2, wherein some yokes of the plurality of upper stepping yokes are positioned on a first surface, wherein other yokes of the plurality of upper stepping yokes are positioned on a second surface, and wherein the first and second surfaces are parallel.

### Claim 5 (depends on 1)

The actuator of claim 1, further comprising a middle actuating sub-assembly for AF and OIS positioned between the stationary sub-assembly and the lens actuating sub-assembly.

### Claim 6 (depends on 1)

The actuator of claim 1, wherein the OIS coil is a single OIS coil and wherein the AF coil is a single AF coil.

### Claim 7 (depends on 6)

The actuator of claim 6, wherein the single OIS coil is mounted on a bottom of the stationary sub-assembly and wherein the single AF coil is mounted on a side of the stationary sub-assembly.
