Patent ID: 7120262

Claim:
A directional-microphone system, comprising: a first figure-of-eight microphone and a second figure-of-eight microphone particularly arranged such that a major axis of the first figure-of-eight microphone and a major axis of the second figure-of-eight microphone extend in parallel with a first axis; a third figure-of-eight microphone and a fourth figure-of-eight microphone particularly arranged such that a major axis of the third figure-of-eight microphone and a major axis of the fourth figure-of-eight microphone extend in parallel with a second axis, the first axis and the second axis being orthogonal to one another; a fifth figure-of-eight microphone particularly arranged such that a major axis of the fifth figure-of-eight microphone extends orthogonal to the major axis of the first figure-of-eight microphone; and a device for phase shifting connected downstream of two of the figure-of-eight microphones whose respective major axes extend orthogonal to one another.
