Abstract
The present invention provides a washer, damper thereof, and control method thereof, by which noise is reduced by adjusting a damping force of the damper in a manner of turning on/off power of the damper according to an oscillation frequency of a vibrating body such as a washer. The control method reduces noise by supplying power to a damper in an excessive vibration state of a vibrating body such as a washer or by cutting off the power supplied to the damper in a normal vibration state of the vibrating body.
