1. A sound signal processing apparatus comprising:
a directional microphone configured to detect a user voice signal comprising a user's voice by arranging the directional microphone to face an utterance point of the user's voice;
a non-directional microphone configured to detect a mixed sound signal comprising the user voice and an external sound;
a processor configured to generate an external sound signal by attenuating the user's voice from the mixed sound signal, by differentially calculating the user voice signal from the mixed sound signal, and process the user voice signal and the external sound signal simultaneously; and
a display configured to display a processing result of the user voice signal and a processing result of the external sound signal in two different regions of the display at a same time, wherein:
the directional microphone comprises vibration structures that vary in length and are configured to sense sound of different frequency bands, and
one side of each of the vibration structures is fixed to a support, and an opposite side of each of the vibration structures extends in a same direction toward a cavity of the support so that extension directions of the vibration structures, from the one side of the support toward the cavity and to the opposite side of the support, are in parallel to one another.
