Abstract
A unidirectional condenser microphone includes a front acoustic terminal disposed on a forward portion of a microphone case, a rear acoustic terminal disposed on the outer circumferential surface of the microphone case, and a directionality varying member disposed on the outer circumferential surface of the microphone case. The directionality varying member switches between a first position and a second position. The directionality varying member covers the rear acoustic terminal at the first position while the rear acoustic terminal is opened at the second position. The front acoustic terminal is displaced ahead of the front surface of the microphone case, and the directionality varying member is in close contact with the outer circumferential surface of the microphone case.
