Abstract
A drive controlling apparatus for driving a vibrating element of an electronic device, which includes, a coordinate detector that detects coordinates of a manipulation input performed on a manipulation input surface: a data storage part that stores basic waveform data representing a basic waveform representing a time change of amplitude of a driving signal for generating a natural vibration in the manipulation input surface, amplitude values arranged in a time series manner constituting the basic waveform; a waveform generating part that generates first waveform data representing a first waveform obtained by changing a basic frequency or the amplitude values; a waveform combining unit that generates first combined waveform data representing a first combined waveform by combining the basic waveform and the first waveform; and a drive controlling part that drives the vibrating element by changing the amplitude of the driving signal based on the first combined waveform data.
