1. A sound modulation apparatus, comprising:

  • a sensor information input unit configured to receive sensing information on a position, at which a touch input of a user is applied to a screen, and a pressure of the touch input applied to the screen; and

    a sound modulation unit configured to set a tone frequency and volume of a sound to be output, and set the tone frequency according to the position, to which the touch input of the user is applied, and set the volume according to a size of the pressure of the touch input,wherein the sound modulation unit includes a volume controlling unit, which determines a reference pressure according to the pressure of the touch input at a predetermined reference time, and sets the volume according to a size of the determined reference pressure, andwherein the sound modulation unit further includes a frequency controlling unit, which sets the tone frequency according to the position, to which the touch input is applied, and changes the tone frequency according to a change in a size of the pressure of the touch input.
