PURPOSE: A linear vibrator is provided to minimize the deformation of a spring due to an external shock or vibration by installing a spring stand between a moving part and a case. CONSTITUTION: A case(120) forms a predetermined space in inside. A permanent magnet(150) and a coil(140) are arranged inside the case. A moving part(130) comprises mass(131) exercising by electro-magnetic power which is created between the permanent magnet and the coil. A circuit board(180) receives a power source from the outside of the case. A spring stand is included between the moving part and the case. The spring stand is arranged in the inner side of a spring. The spring is composed of a coil spring or plate spring. |
