According to the present invention, provided is a linear vibrator, comprising: a coil having a regular space inside; a permanent magnet arranged in the coil; a movement unit including a bearing integrally combined with the permanent magnet; a support axis penetrating a part of the bearing; an elastic member covering the support axis and combined with the movement unit; a bracket supporting both dead ends of the support axis; and a case covering the coil. The low-power small linear vibrator can rapidly respond, can be applied to small electronic devices since the diameter in the vertical direction is small, and can generate excellent vibration power by maximizing vibration power generated from the vibrator due to control of resonant frequency. |
