发明名称 LINEAR VIBRATION GENERATING DEVICE
摘要 PURPOSE: A linear vibration generator is provided to maintain the minimum gap between components by arranging a yoke and a permanent magnet on one side of a heavy body. CONSTITUTION: A linear vibration generator includes a stator(22) and a vibrator(21). The stator includes a bracket and a coil. The vibrator surrounds the outer surface of the coil and includes a yoke(31) and a permanent magnet(32). The yoke includes a horizontal extension unit and a burring unit.
