A sound source separation apparatus comprising: a sound inlet configured to receive a sound; a sound outlet configured to output the sound received through the sound inlet; a plurality of directional vibrators (110_k) arranged on a plane between the sound inlet and the sound outlet, the plane being perpendicular to a central axis of the sound inlet, and the plurality of directional vibrators being arranged around a center point on the plane corresponding to the central axis of the sound inlet in such a manner that one or more of the plurality of directional vibrators is configured to selectively react based on a direction of the sound received through the sound inlet; and characterized in that the sound source separation apparatus further comprises a control circuit configured to: determine a first direction of a first sound source and a second direction of a second sound source that is different from the first sound source, based on strengths of output signals of the plurality of directional vibrators, wherein the second direction of the second sound source is determined during a first time in which the first sound from the first sound source decreases and the second sound from the second sound source increases such that the second sound is relatively strong compared to the first sound and the first direction of the first sound source is determined during a second time in which the second sound from the second sound source decreases and the first sound increases such that the first sound is relatively strong compared to the second sound, and select a first directional vibrator and a second directional vibrator from among the plurality of directional vibrators based on the determined directions to separately obtain a first sound from the first sound source and a second sound from the second sound source, wherein the first directional vibrator is different from the second directional vibrator. a sound inlet configured to receive a sound; a sound outlet configured to output the sound received through the sound inlet; a plurality of directional vibrators (110_k) arranged on a plane between the sound inlet and the sound outlet, the plane being perpendicular to a central axis of the sound inlet, and the plurality of directional vibrators being arranged around a center point on the plane corresponding to the central axis of the sound inlet in such a manner that one or more of the plurality of directional vibrators is configured to selectively react based on a direction of the sound received through the sound inlet; and characterized in that the sound source separation apparatus further comprises a control circuit configured to: determine a first direction of a first sound source and a second direction of a second sound source that is different from the first sound source, based on strengths of output signals of the plurality of directional vibrators, wherein the second direction of the second sound source is determined during a first time in which the first sound from the first sound source decreases and the second sound from the second sound source increases such that the second sound is relatively strong compared to the first sound and the first direction of the first sound source is determined during a second time in which the second sound from the second sound source decreases and the first sound increases such that the first sound is relatively strong compared to the second sound, and select a first directional vibrator and a second directional vibrator from among the plurality of directional vibrators based on the determined directions to separately obtain a first sound from the first sound source and a second sound from the second sound source, determine a first direction of a first sound source and a second direction of a second sound source that is different from the first sound source, based on strengths of output signals of the plurality of directional vibrators, wherein the second direction of the second sound source is determined during a first time in which the first sound from the first sound source decreases and the second sound from the second sound source increases such that the second sound is relatively strong compared to the first sound and the first direction of the first sound source is determined during a second time in which the second sound from the second sound source decreases and the first sound increases such that the first sound is relatively strong compared to the second sound, and select a first directional vibrator and a second directional vibrator from among the plurality of directional vibrators based on the determined directions to separately obtain a first sound from the first sound source and a second sound from the second sound source, wherein the first directional vibrator is different from the second directional vibrator.
