The present invention provides a linear vibration device in which a PCB is coupled to a bracket having an extension piece protruding at a peripheral portion thereof to transfer an external electrical signal to a coil and a yoke of a stator is installed on an upper surface of the PCB to be coupled to the coil, in order to maximally generate an electromagnetic force in one direction. In addition, an upper plate and a lower plate are configured to concentrate a magnetic field of a magnet configured to create a magnetic field corresponding to an electromagnetic force of the yoke formed by the coil to one direction. Accordingly, a vibrating body includes a vibrator which is operated upward and downward in response to an electromagnetic force concentrated by the yoke, increasing vibration feelings due to the upward and downward movement thereof.
