Abstract
A cover or housing member for an electronic device comprises a central region and a perimeter region surrounding the central region. The central region comprises an elevated pattern of radial ribs and elliptical elevations elevated above a generally planar lower surface, such that the cover has multiple vibrational modes of natural resonance in which a maximum deflection of the cover occurs in a first mode at a central point of the cover.
