APPARATUS AND A METHOD FOR RESETTING A RESONANCE FREQUENCY, PARTICULARLY FOR PREVENTING THE REDUCTION OF VIBRATION AMOUNT BY RESETTING A RESONANCE FREQUENCY

摘要

PURPOSE: An apparatus and a method for resetting a resonance frequency are provided to output the maximum vibration despite the change of resonance frequency by updating the resonance frequency in new value.;CONSTITUTION: A driving unit(11) supplies a driving signal of predetermined frequency band, and a vibration generator(12) generates vibration in response to the driving signal. An acceleration sensor unit(13) measures the acceleration of generated vibration, and a filter unit(14) removes a noise from the measured acceleration. A control unit(15) resets up the measured frequency as a resonance frequency of the vibration generator.;COPYRIGHT KIPO 2011
