摘要 |
The present invention provides a linear vibrator comprising a weight having an auxiliary magnet which is provided in a lower end of the weight and generates magnetic force with respect to the bracket. Therefore, a magnetic attractive force between auxiliary magnet and the bracket prevents undesirable fine vibrations and prevents the vibration unit from coming into direct contact with the casing. |
