Disclosed herein is a linear vibrator. The linear vibrator includes a casing defining an internal space. A vibratory unit is accommodated in the casing to vibrate up and down. A spring is mounted at an upper circumferential end thereof to an upper surface of the casing and secured at a lower end thereof to an upper portion of the vibratory unit, thus elastically supporting the vibratory unit. An annular locking ring has a larger outer diameter than an outer diameter of the vibratory unit and an outer diameter of the spring so that the upper circumferential end of the spring is locked to the casing through press-fitting. A bracket supports the casing and the vibratory unit, with a circuit board being mounted on the bracket.
