PURPOSE: A linear vibration motor is provided to minimize a variation of the vibration force and the frequency of a vibrator part by uniformly maintaining a displacement of a printed circuit board, and to increase locking force between a stator part and the printed circuit board performing a linear motion integrally with the vibrator part. CONSTITUTION: A stator part includes a case(100), a bracket(110), a magnet(130), and a plate yoke(150). A vibrator part includes a printed circuit board(180) one end of which is combined with the stator part and the other end of which is combined with the vibrator part, and thereby performing linear and vibration motion integrally with the vibrator part. The case is formed with an internal space to accommodate the linearly moving vibrator part at the inside, and is equipped with a combining part(101) combined with a part of the printed circuit board at the bottom. The magnet is selectively combined with one of the case or the bracket. An elastic component(190) is in the shape of a plate spring, includes an upper plate part(191), a lower plate part(193), and multiple bending parts(195), and is combined with a yoke(140) and the case. |
