Power generating device
First Claim
1. A handheld electronic device, having an automatic charging mode and a manual charging mode, the handheld electronic device comprising:
- a body, having a rechargeable battery and a power generating device, the power generating device having an induction coil, a multipolar magnetic rotor and a driving coil, wherein the driving coil is powered by the rechargeable battery under the automatic charging mode, and drives the multipolar magnetic rotor to rotate, so that the induction coil generates an induction current;
a slide cover, slidingly disposed on the body; and
a manual operating module, disposed on the slide cover, wherein when power of the rechargeable battery is inadequate, the manual operating module drives the multipolar magnetic rotor to rotate, so that the driving coil and the induction coil respectively generate an induction current under the manual charging mode to charge the rechargeable battery.

Abstract
A power generating device includes a carrier module, a stator module, a rotor module and a power generating module. The stator module is assembled to the carrier module, and has a first circuit board and a plurality of driving coils. The rotor module is located in an electromagnetic field, and has a multipolar magnetic rotor and a rotating axle. A magnetic field of the multipolar magnetic rotor interacts with the electromagnetic field to make the rotor module rotating relative to the stator module, and make the multipolar magnetic rotor producing a varying magnetic field. The power generating module is located in the varying magnetic field, and has a second circuit board and a plurality of induction coils. The induction coils induct the varying magnetic field to output an induction circuit to the second circuit board.
