A vibratory actuator control apparatus includes a vibrating member, having an electro-mechanical energy conversion element, and a contact member that contacts the vibrating member. In a second case where the vibrating member and the contact member are brought from a stationary state to a stopped state, an operation sequentially passes through a third stage and a fourth stage. The third stage is for decelerating a relative movement driving speed by applying a driving voltage to the electro-mechanical energy conversion element while maintaining a control parameter of the driving voltage constant and increasing a driving frequency. The fourth stage is for decelerating the driving speed by applying the driving voltage to the electro-mechanical energy conversion element while maintaining the driving frequency constant and decreasing the control parameter of the driving voltage. A start frequency is set based on the driving frequency corresponding to a predetermined driving speed in the third stage.

An optical mechanism is provided for receiving a light that is reflected by a reflecting element. The optical mechanism includes a movable portion, a fixed portion, and a driving module. The movable portion is movable relative to the fixed portion for receiving an optical member that defines an optical axis. The driving module includes a first electromagnetic driving assembly and a second electromagnetic driving assembly for driving the movable portion to move relative to the fixed portion. The optical axis is located between the first electromagnetic driving assembly and second electromagnetic driving assembly when viewed from the optical axis, and the first electromagnetic driving assembly and the second electromagnetic driving assembly are electrically independent from each other.

A camera assembly comprises a lens assembly supported on a support structure, wherein the lens assembly includes an autofocus actuator arrangement and the camera assembly includes an optical image stabilization assembly arranged to move the lens assembly in a plane perpendicular to the optical axis. A flexible printed circuit tape connected between the support structure and the lens assembly and providing an electrical connection to the auto-focus actuator arrangement is bent around a corner, thereby allowing the flexible printed circuit tape to accommodate the motion of the lens assembly perpendicular to the optical axis. A crimp plate connected to the lens assembly which crimps shape memory alloy wires has features extending out of the plane of the crimp plate for reducing flexibility. At least part of the optical image stabilization assembly overlaps the lens assembly in the direction along the optical axis, thereby reducing the height of the camera assembly.
