An active vibration control device is provided that is configured to control the position of a body relative to a reference frame. The control device includes sensors that provide input signals corresponding to movement of the body in at least one direction, a rotary motor configured to control the position of the body, and four-bar linkage connecting the rotary motor to the body. The linkage converts the rotary motion output from the motor into a linear motion of the body. The controller, based on the input signals from the reference frame sensors, provides control signals to the rotary motor which acts through the linkage to position the body in the at least one direction relative to the position of the reference frame.
