Movable touch module and electronic device using the same

An electronic device comprising:

• a main body;
• and
• a movable touch module disposed at the main body, the movable touch module including:
• a movable element disposed at the main body and being movable relative to the main body on a plane, the movable element having a first containing area;
• a touch unit fastened to the movable element;
• a plurality of elastic units disposed at the main body and being against the periphery of the movable element;
• a four-direction sensing element fastened to the main body and located in the first containing area of the movable element;
• and
• at least two rotation sensing elements fastened to the main body and located in the first containing area of the movable element,
• wherein when the movable element moves along a direction on the plane, the movable element correspondingly triggers the four-direction sensing element along the direction, and when the movable element rotates on the plane, the movable element correspondingly triggers one of the rotation sensing elements.
