Abstract
Method and dynamic vibration absorber device for reducing a resonant frequency of a node to which the dynamic vibration absorber device is attached to. The dynamic vibration absorber device includes a housing configured to be attached to the node; an absorber mass located inside the housing; and first and second diaphragms attached to the housing and configured to suspend the absorber mass inside the housing. The dynamic vibration absorber device changes a resonant frequency of the node to two smaller vibration peaks.
