Abstract

The present invention relates to a device and a method for generating a shock-type response signal by which vibration can be suppressed. The characteristics (a frequency, a frequency vibration magnitude, and a slope) of a frequency component having the largest vibration, among frequency components constituting a vibration signal, are determined through vibration measurement, and then the supply of a shock response signal is preprogrammed in a control unit (200) together with a response signal supply time point. In addition, when the occurrence and size of vibration are sensed by a sensor (100) and are transferred to the control unit (200), a shock response signal corresponding to the vibration magnitude of the frequency component, which has been pre-determined in the control unit (200), is generated and transferred, and an actuator (300) is driven by the transferred signal. Accordingly, by supplying the shock response signal, vibration can be efficiently suppressed without a side effect in which vibration becomes stronger. When vibration remains after the shock response signal is supplied, the control unit (200) may be repeatedly operated to additionally supply a response signal.
