Abstract
A microphone array for providing a focused field of optimum audio reception is disclosed. The array has a series of interconnected microphones spaced within a housing. At a midpoint of the spaced microphones is an illuminated polarized centering marker which gives the user a visual signal that the user is located within the optimum filed of audio reception. The housing can be placed on the top front edge of video monitor and has slideably mounted removable feet, which allow the microphones to be aimed more accurately at the user. The array is foldable along a midpoint, which allow for compact storage. The folding mechanism is a hinge, which has a hollow core, and openings which allow the internal wiring to interconnect two wings of the array without exposing the wires. The wings are held in their longitudinally oriented position by a latching mechanism of pins in one wing which snap fit into capture boots within the other wing. Microphones are maintained in sound deadening pods, which absorb side and rear audio signals and provide rear pressure relief.
