Abstract
A novel microphone assembly including three microphones which are rotatably or pivotably supported relative to each other and relative to a supporting handle housing structure wherein the left and right microphones rotate the same amount relative to a center axis of the microphone structure and wherein the center microphone can be extended different lengths and directed in different directions so as to vary the mixing ratio relative to the other microphones and including a ganged variable resistor to which the center microphone is connected so as to automatically control the mixing ratio between the signal from the center microphone with the two outer left and right microphones. The microphone assembly can be folded into a compact package and the microphone has superior localization characteristics for reproduction of sound.
