Disclosed is a linear vibrator including a fixing part providing an inner space of a predetermined size, at least one magnet disposed in the inner space of the fixing part to generate a magnetic force, a vibration part including a coil disposed to face the magnet to generate electromagnetic force by interacting with the magnet and a vibrating mass body, an elastic member coupled to the fixing part and the vibration part to provide an elastic force, and a substrate coupled to the vibration part and including a through hole through which the magnet passes to prevent the substrate from contacting the magnet when the vibration part is vibrated. |
