Abstract
A system and a method are provided for vibrating a portable device. The system includes a vibrator housing with stops, a vibrator circuit, and a controller. The controller has an output to supply alternating electric current. The vibrator circuit includes a vibrator coil and a magnetic vibrator rod. The vibrator coil is made of a conductive material and has an inside core space and inputs to accept the alternating electric current. The vibrator coil generates an alternating magnetic field through the core space in response to the alternating electric current and the vibrator rod moves in a reciprocating linear fashion in the core space in response to the alternating magnetic field. The vibrator rod has ends with audio damping pads impacting against stops in the vibrator housing. The vibrator housing vibrates in response to the vibrator rod impacting against the stops. The controller has an input for selecting frequency commands in response to predetermined portable device conditions and supplies electric current alternating at a frequency responsive to the commands. In one aspect, the portable device is a wireless communications device and the controller selects commands in respons…
