VIBRATION GENERATING APPARATUS, OPERATING METHOD THEREOF, AND APPARATUS INCLUDING VIBRATION GENERATING APPARATUS

Abstract:

A vibration generating apparatus comprises a vibration apparatus and a vibration driving circuit including a driving signal generator configured to supply a driving signal to the vibration apparatus, wherein the driving signal generator is configured to adjust a frequency-based gain compensation value based on at least one of a circuit internal temperature value of the vibration driving circuit and a temperature prediction value of the vibration apparatus corresponding to a current value of an n.sup.th driving signal, compensate for a frequency-based gain value based on the adjusted frequency-based gain compensation value, compensate for an (n+1).sup.th driving signal based on the compensated frequency-based gain value, and supply the compensated (n+1).sup.th driving signal to the vibration apparatus.
