PURPOSE: An automatic vibration intensity control module, an electric toothbrush using the same, and a control method thereof are provided, which control the vibration intensity of the vibration machine. CONSTITUTION: An automatic vibration intensity control module includes a direction detector(140), a controller(120), a memory(170), and a printed circuit board(190). The direction detector is comprised of a motion sensor and detects direction of the X,Y,Z axes of a module, change of movement of the angular orientation, and whether one-axis of the X,Y,Z axes is in parallel to the gravity direction or not. The controller is comprised of a miniature MICOM or a logic circuit and outputs a signal controlling vibration intensity to a vibration intensity controlling element(121). |
