Avibration-reduction an driving circuit is applicable to a fan that operates according to a current signal sent thereto, and is characterized in a current buffer unit connected to a drive current supplied from a power source and having a relatively large magnitude of change in current. The current buffer unit divides the original drive current into multiple continuously changing drive currents that have a relatively small magnitude of change in current, so that electric current supplied to the fan is regulated and output fractionally to achieve the purpose of reducing the vibration of fan caused by a large magnitude of change in current.
