PIEZOELECTRIC ELEMENT DRIVING APPARATUS

摘要

The present invention relates to a piezoelectric element driving apparatus. The present invention provides the piezoelectric element driving apparatus capable of quickly driving a piezoelectric element without driving noises by receiving a first digital vibration signal sampled into a first frequency in an audible frequency, resampling the first digital vibration signal into a second frequency which is higher than the first frequency, and driving the piezoelectric element through a second digital vibration signal with a frequency band changed into the second frequency by resampling without noises.
