HAPTIC MODULE

摘要

PURPOSE: A haptic module which click sensation is improved is provided to apply a sine wave type voltage to a piezoelectric element and prevent noise generation, thereby reducing instant power consumption. CONSTITUTION: A panel unit(140) is installed in an upper side of a base(110) to be elevated. A vibration member(120) is arranged between the base and the panel unit. The vibration member supports the panel unit to be elevated. A piezoelectric element is installed in the vibration member and generates vibration in the vibration member. A controlling unit controls power applied to the piezoelectric element. The piezoelectric element is transformed by the power applied by the controlling unit. The piezoelectric element generates the vibration of up and down direction in the vibration member and the panel unit.
