1. A small-sized power package comprising:
- a tubular case having a tubular receptacle in an internal portion thereof, wherein two shaft supporting elements are protruded from an external surface of said tubular case and are respectively arranged at a front end and a rear end of said tubular case;
a magnet tube accommodated within said tubular receptacle of said tubular case, and having a hollow magnet receptacle in an internal portion thereof;
a coil sheathed around an external surface of said magnet tube, and having a positive end and a negative end;
a power-generating magnet is accommodated within said hollow magnet receptacle of said magnet tube;
a shaft having both ends respectively fixed on said two shaft supporting elements;
a movable box hung on said shaft and movable with respect to said shaft;
a positioning magnet disposed within said movable box for attracting said power-generating magnet, so that said power-generating magnet is suspended in said hollow magnet receptacle of said magnet tube; and
two protective caps arranged on said front end and said rear end of said tubular case for restricting said magnet tube within said tubular case,wherein when said movable box is moved with respect to said shaft, said power-generating magnet is attracted by said positioning magnet to move, thereby producing electric energy between said positive end and said negative end of said coil.

Abstract
A small-sized power package includes a tubular case, a magnet tube, a coil, a power-generating magnet, a shaft, a movable box, and a positioning magnet. The power-generating magnet is attracted by the positioning magnet and thus suspended within the magnet tube. The small-sized power package has enhanced power generating efficiency by utilizing the benefit of magnetic levitation. An electronic device including such a small-sized power package is also provided.

5. An electronic device having a small-sized power package, said electronic device comprising:
-
a circuit board; and a small-sized power package comprising; a tubular case having a tubular receptacle in an internal portion thereof, wherein two shaft supporting elements are protruded from an external surface of said tubular case and are respectively arranged at a front end and a rear end of said tubular case; a magnet tube accommodated within said tubular receptacle of said tubular case, and having a hollow magnet receptacle in an internal portion thereof; a coil sheathed around an external surface of said magnet tube, and having a positive end and a negative end; a power-generating magnet is accommodated within said hollow magnet receptacle of said magnet tube; a shaft having both ends respectively fixed on said two shaft supporting elements; a movable box hung on said shaft and movable with respect to said shaft; a positioning magnet disposed within said movable box for attracting said power-generating magnet, so that said power-generating magnet is suspended in said hollow magnet receptacle of said magnet tube; and two protective caps arranged on said front end and said rear end of said tubular case for restricting said magnet tube within said tubular case; and two springs sustained against said circuit board and supporting said small-sized power package, wherein when an external force is exerted on the electronic device, elastic forces offered by said springs allow said front end and said rear end of said tubular case to be swung up and down, thereby producing electric energy between said positive end and said negative end of said coil. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
