Abstract
An electronic device includes a housing, a speaker, control circuitry, a plurality of light-emitting components configured to emit light through an upper housing wall or other housing structure. A lens diffuser layer having lenses overlapping respective light-emitting components, a textured diffuser layer formed from textured coatings on a substrate, and a volume diffuser layer having light-scattering structures in a polymer layer might be included to project light from the light-emitting components. A light-guiding portion of the lens diffuser layer may guide light to a circular peripheral edge to form an illuminated ring visible through the upper housing wall.
