    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: 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.

    Abstract: A filter system includes a first resonator having a first resonant frequency, and a second resonator having a second resonant frequency different from the first resonant frequency, and electrically connected to the first resonator. A first response characteristic of the first resonator and a second response characteristic of the second resonator with respect to a frequency include a first section in which a first phase of the first resonator is equal to a second phase of the second resonator, and a second section in which the first phase is different from the second phase by 180 degrees. A first electrode of the first resonator is reversely connected to a second electrode of the second resonator.
