Electromagnetic actuators for digital cameras

A digital camera module comprising:

• a) an optical element;
• and
• b) an actuator assembly comprising two actuators and operative to provide the optical element with double tilt and linear motion capabilities, each actuator comprising:
• i. a first elongated ferromagnetic member surrounded partially by a conductive coil, the first ferromagnetic member having a first longitudinal axis and a first operative surface,
• ii. a second elongated ferromagnetic member having a second longitudinal axis parallel to the first longitudinal axis and a second operative surface, the first and second ferromagnetic members disposed such that a gap and an overlap are formed between the first and second operative surfaces, and
• iii. a frame hinge having a third longitudinal axis parallel to the first and second longitudinal axes, the frame hinge used to enable one ferromagnetic member to undergo a tilt motion relative to the other ferromagnetic member when a magnetic force is generated by current in the coil, the tilt motion convertible into a linear displacement of the optical element from a first position to a second position.
