PURPOSE:To make the angle of directional direction provided with the moving member provided movably in the intermediate direction of a pair of microphones variable. CONSTITUTION:When an operator 23 is moved in the direction shown by the arrow A, both microphones 11, 12 approach and the angle of their directional direction becomes small. When the microphones 11, 12 are subsequently moved apart, the mixing level lowers. Because of this, if the angle of the directional direction of the microphones 11, 12 is increased, the mixing level lowers and therefore the respectively separate acoustic signals are obtained from both microphones 11, 12 by way of microphone plugs 26, 27. |
