Abstract
A directional microphone and an operating method thereof include a first signal generator generating a first sound signal corresponding to a front sound coming through a front sound hole of the directional microphone. A second signal generator generates a second sound signal corresponding to a rear sound coming through a rear sound hole of the directional microphone. A phase delay controller delays a phase of the rear sound coming through the rear sound hole, and a signal processor synthesizes the first sound signal and the second sound signal.
