Abstract: Provided is a sound direction detection sensor capable of detecting a direction from which sound is coming by using a multi-resonator array. The disclosed sound direction detection sensor includes two resonator arrays, each including a plurality of resonators having different resonance frequencies. The two resonator arrays have different directivities. Each resonator array serves as an audio sensor, and the sound direction detection sensor detects a direction from which sound is incident, regardless of a distance between audio sensors.
