PURPOSE: A linear type vibration generator is provided to increase vibration force or to achieve compactness without an additional yoke flat part as reducing costs by using an adhesive agent in combining an inner side and an outer side of a cylinder. CONSTITUTION: A vibrator is constituted with a coil(630) and a weight body(644). A stator shell is constituted with a case and a base. A magnet(642) is combined to a center in the case or the base. A flat yoke(643) is combined to another plane of the magnet. The stator is constituted with the magnet and the flat yoke. A spring is connected to the vibrator and the stator, and the inside of the spring has a vacant cylindrical shape. The coil is combined to the inside of the spring, and the weight body is combined to the outside of the spring to support linear movement of the vibrator. One side of a printed circuit board(611a) is attached to the base, and the other side of the printed circuit board is attached to the vibrator. A current is applied to the coil through the printed circuit board. |
