摘要: A vibrator assembly includes a housing defining a longitudinal central axis and a rotor in the housing and spaced apart from the central axis. The rotor defines a longitudinal rotational axis that is parallel to the central axis. The rotor is configured to rotate about the rotational axis and, in response, to rotate about the central axis.
