1. A directional acoustic sensor comprises:
a support member; and
a plurality of resonators extending in a longitudinal direction with respect to the support member,
wherein each of the plurality of resonators comprises:
a driver configured to move based on an input sound signal; and
a sensor configured to sense a capacitance change based on an air gap that changes based on a movement of the driver.
