  • Speaker Grill with Graduated Hole Sizing over a Transition Area for a Media Device
    Publication number: 20180098140
    Abstract: A grill cover that fits over or is positioned over high frequency acoustical regions and low frequency acoustical regions of a playback device. A portion of the grill cover that fits over or is positioned over a high frequency acoustical region has small area openings and a portion of the grill over a low frequency acoustical region has large area openings. In portions of the grill cover between the portions over high and low frequency acoustical regions, the openings may have an intermediate area to visually blur the differences between the portions of the grill covers. To further blur the differences, the differently sized openings may be interleaved.
