Abstract
An oscillator assembly includes a first eccentrically weighted rotor having a first eccentric weight configured to rotate about an axis, a second eccentrically weighted rotor having a second eccentric weight configured to rotate about the axis. Rotation of the first eccentrically weighted rotor is coupled to rotation of the second eccentrically weighted rotor. An actuator is configured to vary an angular separation between the first eccentric weight and the second eccentric weight.
