Abstract: An electronic device includes a tablet module and a docking base. The tablet module includes a slot, a sliding element and a plurality of first attracting elements. The sliding element is slidably disposed in the slot. The first attracting elements are adjacently disposed on the sliding element and have a first attracting side. The polarities of each two adjacent first attracting elements at the first attracting side are different. The docking base includes a bearing sheet and a plurality of second attracting elements. The bearing sheet is inserted to the slot and abuts against the sliding element. The second attracting elements are adjacently disposed on the hearing sheet and have a second attracting side. The polarities of each two adjacent second attracting elements at the second attracting side are different.

Abstract: The present invention provides a vibration pickup, which is comprised of a main body, a torsion-bar spring located on the main body, a swing arm and a trigger head, wherein, a moving contact is built upon the bottom side of the swing arm orienting to the sway downward, a stationary contact is built upon the proper position coordinating to the moving contact on the main body so as to bring them to touch against exactly, when the swing arm is swung by extra vibration from the outside, the moving contact is moved down along with swing arm to strike on the stationary contact exactly to bring the switch to close-state instantly. Comparing with the prior art, the present invention has a simplified structure with higher induction sensitivity.
