PURPOSE: A linear rotator is provided to improve magnetic efficiency by dividing a coil which generates vibration into two parts to be arranged on a central shaft. CONSTITUTION: A permanent magnet(130) is positioned on the outside of upper and lower coils(111, 112). A vibrator(150) vertically vibrates with the permanent magnet. A spring(160) limits the width of the vibration of the permanent magnet and the vibrator in a vertical direction. A case(180) accommodates the upper and lower coils, the permanent magnet, the vibrator, and the spring. A circuit board(190) inputs a first electrical signal to the upper coil and inputs a second electric signal to the lower coil. |
