PURPOSE: A linear vibration device is provided to improve productivity and durability by managing only one side gap between a coil and a magnet and semi-permanently preserve the lifespan of a vibration motor by not using a brush and a commutator. CONSTITUTION: A bottom plate(22) is combined in order to concentrate the magnetic direction of the magnet to one side direction. A top plate(24) is combined in order to concentrate the magnetic direction of the magnet to one side direction. A vibrator is composed in order to enhance sensory vibration and is combined with the top plate. An elastic member(31) is combined with the upper surface of the top plate and is composed in order to help the movement of a vibrating body. A case(32) is combined with the elastic member and transfers vibrating sound to outside.
