    Abstract: Provided are sound direction detection sensors capable of detecting an input direction of sound and electronic apparatuses including the same. A sound direction detection sensor includes a sound inlet receiving input sound, a sound outlet outputting the sound input through the sound inlet, and a plurality of directional vibrators arranged between the sound inlet and the sound outlet in such a manner that at least one directional vibrator selectively reacts based on a direction of the sound input through the sound inlet, wherein a direction perpendicular to a direction of a directional vibrator having a lowest output in magnitude among the plurality of directional vibrators is determined as an input direction of the sound.

    Abstract: A compact directional acoustic sensor having an improved signal-to-noise ratio is disclosed. The disclosed directional acoustic sensor includes a first sensing device configured to generate different output gains based on different input directions of external energy, and configured to generate at least one first output signal having a first polarity based on external energy received from an input direction; a second sensing device configured to generate different output gains based on different input directions of external energy, and configured to generate at least one second output signal having a second polarity, that is different than the first polarity, based on the external energy received from the input direction; and at least one signal processor configured to generate at least one final output signal based on the at least one first output signal and the at least one second output signal.

    Abstract: Provided are a sound source separation apparatus and a sound source separation method. The sound source separation apparatus includes a plurality of directional vibrators configured such that one or more of the plurality of directional vibrators react to a sound based on a direction of the sound. The sound source separation apparatus is configured to determine directions of a first sound source and a second sound source that are different from each other, based on strengths of output signals of the plurality of directional vibrators, and select a first directional vibrator and a second directional vibrator that are different from each other from among the plurality of directional vibrators to separately obtain a sound coming from the first sound source and a sound coming from the second sound source.
