ELECTRONIC DEVICE

An electronic device includes a first casing, a second casing, a target, a smasher, an elastic component, and a stopper. The second case is suitable for assembly to the first case, and the second case includes a push element and a stop rib. The target, the smasher and the elastic component are accommodated in an accommodating space of the first casing. The smasher is movably located on one side of the target. The elastic component provides an elastic force to drive the smasher to move to the target. The stopper is movably snapped the smasher. When the second case is assembled to the first case, the push element moves against the stopper and releases the smasher, the smasher moves toward the target until the stop rib disposed between the smasher and the target and stopped the smasher. When the second case is detached from the first case to remove the stop rib, the smasher moves to the target by the elastic force of the elastic component and hit the target.
