PURPOSE: A vibration generator prevents the separation of a magnet due to external impact by including a magnet separation prevention unit made of nonmagnetic materials. CONSTITUTION: A magnet (120) is installed in a housing (110). A vibrator (130) includes a coil facing the magnet. One end and the other end of an elastic member (140) are installed on the housing and the vibrator, respectively. A magnet separation prevention unit (150) faces the magnet to prevent the separation of the magnet. A yoke plate (160) is installed on the magnet to reduce magnetic loss. |
