Abstract
A linear vibration generating device installed inside a cellular phone, a vibration bell or the like to generate vibration. Right after the power applied to the 'circuit (a circuit generating and controlling vibration)', which is one of elements constituting the linear vibration generating device, is turned off, the 'circuit' is configured as a short circuit. In addition, the linear vibration generating device can be easily manufactured since an additional space inside the linear vibration generating device is not required, and there is an outstanding effect of promptly removing residual vibration by increasing the amount of vibration damping after the vibration operation of the vibration generating device including a permanent magnet is finished.
