Abstract
Provided is an electronic device including a modulation unit () that modulates a sound signal to a modulation wave for a parametric speaker; an oscillator () to which the modulation wave is input; an equalizer () that corrects a frequency characteristic of a sound wave that is demodulated by the modulation wave; and a control unit () that selects a carrier frequency of the modulation wave and changes setting of the equalizer () on the basis of the selected carrier frequency. Thus, it is possible to provide the electronic device capable of correcting the frequency characteristic of the sound wave that is demodulated, for each carrier frequency of the modulation wave.
