The present invention relates to an electricity generating device. According to an embodiment of the present invention, the electricity generating device is capable of generating induced electromotive power for a coil by an interaction between the coil and magnetic force of a magnet as the magnet in an inner space of a case penetrates the coil, wound on an outer part of the case. The device includes a joint assembly, combined with the case, and including a globular connection part; and a vibrator linked with the connection part to slide, and including a magnet. Therefore, the vibrator, including the magnet, slides around the joint assembly according to the movement of the case. Since the induced electromotive power is generated in the coil by the interaction between the coil and the magnetic force of the magnet, the power is able to be used for a small power source of a wearable electronic product. |
