Power generating device and an object for utilizing the power generating device

A power generating device, comprising:

• a first shell, having a first hollow portion and a first opening portion;
• a sensor module, configured in the first hollow portion of the first shell, wherein the sensor module comprises a magnetism element and an induction coil coiled on the magnetism element, wherein the magnetism element comprises a first terminal and a second terminal, and a first slide gap is formed between the first terminal and the second terminal, wherein the magnetism element comprises a first sensor arm and a second sensor arm, and the first sensor arm and the second sensor arm are separable;
• a second shell, having a second hollow portion and a second opening portion, the second shell having a hole;
• a magnetic module comprising a first magnetism element;
• a cover, disposed above an external surface of the second shell, the cover comprising a convex portion which penetrates the hole and couples the magnetic module;
• and
• an elastic element, disposed between the first shell and the second shell.

An object for using a power generating device, wherein:

• the object having an accommodating space for holding the power generating device;
• the power generating device comprises:
• a first shell, having a first hollow portion and a first opening portion;
• a sensor module, configured in the first hollow portion of the first shell, wherein the sensor module comprises a magnetism element and an induction coil coiled on the magnetism element, wherein the magnetism element comprises a first terminal and a second terminal, and a first slide gap is formed between the first terminal and the second terminal, wherein the magnetism element comprises a first sensor arm and a second sensor arm, and the first sensor arm and second sensor arm are separable;
• a second shell having a second hollow portion and a second opening portion;
• a magnetic module comprising a first magnetism element;
• wherein when an external force is applied to the power generating device, a distance of the relative movement between the first magnetism element and the magnetism element is between 2 mm and 5 mm, and the first magnetism element moves in the slide gap through the direction of the external force with respect to the magnetism element for generating an induced voltage which is higher than 3 volts.
