A linear vibrator includes a fixed part providing an interior space having a predetermined size; at least one magnet disposed in the interior space and generating magnetic force; a vibration part including a coil facing the magnet and generating electromagnetic force through interaction with the magnet and a mass body; and a substrate having one end coupled to the vibration part to thereby serve as a free end, and the other end including a copper foil pattern portion coupled to the fixed part to thereby serve as a fixed end. The fixed part includes an exposure hole penetrating a top and bottom surface thereof or an exposure groove recessed from an outer end of the fixed part. The exposure hole or groove is formed on the protrusion portion. The copper foil pattern portion is coupled with a part of the protrusion portion defining the exposure hole or groove. |
