A vibrator assembly (108) comprising a shaft (112) that is connected to a motor (110), to produce vibration in a communication device (500), is disclosed. The shaft (112) includes a track that defines a path with a first component that travels circumferentially around the shaft (112), and a second component that travels along the length of the shaft (112). The shaft (112) rotates due to a rotational force that is generated when the motor (110) is activated. The unbalanced mass (114) travels along the track towards an end of the path proximate a free-end of the shaft (112) when the motor (110) is activated, and retracts due to a biasing force from a tension device (212) when the motor (110) is deactivated.
