Patent ID: 8761405

Claim:
A narrow directional stereo microphone comprising: a mid capacitor microphone unit having narrow directionality disposed such that a directional axis of the mid capacitor microphone unit aligns to a major axis of a microphone body; and a unidirectional right capacitor microphone unit and a unidirectional left capacitor microphone unit disposed symmetrically with respect to the major axis such that directional axes of the unidirectional right and left capacitor microphone units are perpendicular to the major axis, wherein signals output from the mid capacitor microphone unit are sent to one of a diaphragm and a fixed electrode of the unidirectional right capacitor microphone unit and to one of a diaphragm and a fixed electrode of the unidirectional left capacitor microphone unit, and right channel signals are output from the other of the diaphragm and the fixed electrode of the unidirectional right capacitor microphone unit, and left channel signals are output from the other of the diaphragm and the fixed electrode of the unidirectional left capacitor microphone unit.
