Abstract
The invention provides a vibration controlling method which amplifies a steady state voltage and generates a first voltage signal for controlling the vibrator to accelerate vibration to a target vibration amplitude lower than the steady state vibration amplitude, and then attenuates the startup voltage to the steady state voltage to generate a second voltage signal for controlling the vibrator to vibrate from the target vibration amplitude to the steady state vibration amplitude. Through the implementation of the invention, the steady state voltage is amplified and used as an excitation voltage of the acceleration section of vibrator vibration, and then it steadily decreases to the steady state voltage, which effectively shortens the acceleration time for the early stage of the vibrator vibration response and reduces the hysteresis of the vibrator vibration fed back to the user.
