Abstract: A tactile vibration control system and method for a smart terminal. The system includes a command generator, a filter, a tactile driver and a linear resonant actuator; the command generator generates an initial commanding signal according to an input signal; the filter filters the initial commanding signal so that amplitudes of a predetermined number of initial pulses of the filtered commanding signal are larger than a set threshold and phases of a predetermined number of ending pulses reverse; and the tactile driver generates a driving signal according to the filtered commanding signal for driving the actuator to vibrate. The initial commanding signal generated by the command generator is filtered so that when the actuator is driven to vibrate by the driving signal generated subsequently, the actuator has a quick starting response and a quick braking response.
