  • Publication number: 20200393121
    Abstract: An electronic device such as a voice-controlled speaker device may have a housing. A speaker and other input-output components and control circuitry may be mounted within the housing. A set of controlled light-emitting components may emit light that passes through an upper housing wall or other housing structure. Light from the light-emitting components may be spread laterally by multiple light diffusing layers such as 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. The lens layer may be formed from a transparent member with integral lenses having curved inner surfaces and opposing curved outer surfaces and central depressions. A light-guiding portion of the transparent member may guide light to a circular peripheral edge to form an illuminated ring visible through the upper housing wall.
