Abstract:
1. An electronic device, comprising: a first case; a second case assembled to the first case to form an accommodating room together, the second case having an opening exposing the accommodating room; a plurality of first magnets disposed at the first case; a plurality of electromagnets disposed at the second case; a display module disposed at the accommodating room, wherein the opening exposes the display module; a plurality of second magnets disposed at the display module correspondingly to the first magnets and the electromagnets; and a sensing unit electrically connected to the electromagnets, wherein when an acceleration sensed by the sensing unit is less than a threshold value, the sensing unit controls the electromagnets and the second magnets to attract each other magnetically to fix the display module, and when the acceleration sensed by the sensing unit is larger than the threshold value, the sensing unit controls the electromagnets and the second magnets to repel each other magnetically to make the display module suspended.
