Porous solid wind screen for microphone
A porous solid windscreen formed of metal, plastic or the like covers the microphone without the need for the familiar large foam ball of material over the microphone. In a disclosed embodiment, the windscreen is a monolithic structure formed by sintering the material so as to produce a relatively consistent and desired sized pore structure. The wind screen is preferably sintered while in a mold, thereby allowing it to be formed in a variety of form factors including substantially arcuate structures or non-symmetrical structures and the like to accommodate desired aesthetic and/or acoustic needs.
