摘要： A child motion device includes a frame (22) providing a structural support (28) relative to a reference surface (25) and including an arm (30) pivotably coupled to the structural support (28) for reciprocating movement with a resonant frequency, a child supporting device (36) coupled to the arm (30) and spaced from the reference surface (26) by the frame (22), and a drive system including a motor configured to drive the arm (30) such that the child supporting device (36) reciprocates along a motion path at a frequency matched to the resonant frequency. The drive system is configured to adjust a duty cycle of the motor to control a speed at which the child support device moves along the motion path.
