  • Patent number: 10976486
    Abstract: Devices that include light assemblies for providing visual feedback to users that operate the electronic devices. In some instances, the devices comprise voice-controlled devices and, therefore, include one or more microphones for receiving audible commands from the users. After receiving a command, for instance, one such voice-controlled device may cause a corresponding light assembly of the device to illuminate in some predefined manner. This illumination may indicate to the user that device has received the command. In other instances, the devices may illuminate the lighting assembly for an array of other purposes. For instance, one such device may illuminate the corresponding light assembly when powering on or off, playing music, outputting information to a user (e.g., via a speaker or display), or the like.
