Claim:
1. A microphone array comprising: three pairs of microphones; a mechanical support for supporting each pair of microphones at one spatial axis of three orthogonal spatial axes, the three orthogonal spatial axes comprising two horizontal spatial axes and one vertical spatial axis; and a seventh microphone placed at the position in which the three orthogonal spatial axes intersect each other, wherein the mechanical support comprises a first horizontal mechanical axis, a second horizontal mechanical axis, and a third vertical mechanical axis being placed off-center with respect to the vertical spatial axis and intersecting, at a cross-point, the first horizontal mechanical axis or the second horizontal mechanical axis, wherein an upper horizontal rod and a lower horizontal rod are fixed to the third vertical mechanical axis, the upper horizontal rod and the lower horizontal rod being parallel to the first horizontal mechanical axis or the second horizontal mechanical axis, and wherein the third vertical mechanical axis is fixed to one of the first horizontal mechanical axis or the second horizontal mechanical axis at the cross-point located between a place for the seventh microphone and a neighboring microphone of one pair of the three pairs of microphones.
