A directional acoustic sensor is disclosed. The directional acoustic sensor comprises: a support member; and a plurality of resonators prepared to extend in a longitudinal direction with respect to the support member. The resonators comprise: a driving unit that moves in response to an input acoustic signal; and a sensing unit that senses a capacitance change due to an air gap that changes according to movement of the driving unit. 지향성 음향 센서가 개시된다. 개시된 지향성 음향 센서는, 지지부재와, 지지부재에 대해 길이 방향으로 연장되어 마련되는 복수의 공진기를 포함한다. 공진기는, 입력되는 음향 신호에 반응하여 움직이는 구동부와, 구동부의 움직임에 따라 변화하는 에어갭에 따른 커패시턴스 변화를 센싱하는 센싱부를 포함한다.
