Benefits of technology

[0030]As described above, the vibration of a low frequency band at which excessive vibration occurs may be reduced.
[0031]In addition, by redu

Problems solved by technology

However, the force generated during the rotation of the drum is delivered to the tub surrounding the drum, thereby generating vibration.
However, in a case when a ball is positioned in the same direction as the laundry at the uneven state during a transient state, that is, a range prior to the natural frequency of a system, the ball may cause the imbalance, resulting in increased vibration.
However, the natural frequency of the dynamic absorber is to reduce the vibration of a high freq
