Linear vibration generator
A linear vibration generator is disclosed. The linear vibration generator in accordance with an embodiment of the present invention includes a stationary part, which has a polygonal-prism-shaped coil and in which the polygonal-prism-shaped coil induces a magnetic field by having an electric current supplied, a vibrating part, which has a polygonal-prism-shaped magnet and in which a portion of the polygonal-prism-shaped magnet is inserted into the coil, an elastic member, which is coupled to the stationary part and elastically supports the vibrating part such that the vibrating part can move linearly, and a lubricating band, which is formed on an outer circumferential surface of the magnet.
