POWER GENERATING DEVICE
First Claim
1. A power generating device, comprising:
- a first casing, having at least one first engagement part;
a second casing, having at least one second engagement part, the second engagement part being movably coupled to the first engagement part to form a space between the first casing and the second casing;
a magnetic component, fixed on the first casing;
an induction coil, fixed on the second casing and configured in the space, the induction coil positioned outside the contour of the magnetic component; and
a first piezoelectric component, configured between the magnetic component and the second casing;
wherein, when an external force acts on the power generating device, the first casing and the second casing move relatively to each other so that the induction coil generates an induced current by sensing a magnetic flux variation, and the first piezoelectric component generates a first charge by absorbing the pressure between the magnetic component and the second casing.

Abstract
A power generating device includes a first casing, a magnetic component, a second casing, an induction coil, and a first piezoelectric device. The first casing and the second casing engage with each other to form a space, and the magnetic component is fixed on the first casing and configured in the space. The induction coil is fixed on the second casing and configured in the space, and it is positioned outside the contour of the magnetic component. The first piezoelectric is configured between the magnetic component and the first casing. When an external force acts on the first casing and the second casing, the first casing and the second casing move relatively to each other so that the induction coil generates an induced current by sensing a magnetic flux variation, and the first piezoelectric component generates a first charge by absorbing the pressure between the magnetic component and the second casing.
