    Abstract: A method for operating a distributed wireless audio system including several loudspeaker cabinets all of which can communicate with each other as part of a computer network. The method receives temperature data that is indicative of temperature of a first loudspeaker cabinet, which has a network master responsibility of obtaining an audio signal from an audio source and wirelessly transmitting some of the audio signal to a second loudspeaker cabinet of several loudspeaker cabinets, for playback by the second loudspeaker cabinet, while playing back some of the audio signal by the first loudspeaker cabinet. The method determines whether a thermal threshold of the first loudspeaker cabinet has been reached, based on the temperature data. The method, in response to the thermal threshold being reached, gives up the network master responsibility from the first loudspeaker cabinet to the second loudspeaker cabinet, where doing so reduces temperature in the first loudspeaker cabinet.

    Abstract: This application relates to a layout of components within an electronic device. The electronic device includes a circuit board and one or more thermal components located on or proximate to each surface of the circuit board. As a result, thermal energy generated by components of the circuit board are drawn away from the circuit board in a more efficient manner. Additionally, the electronic device may include one or more air movers designed to draw ambient air into the electronic device in a manner that causes the ambient air to cool components upstream from the air movers. Further, the electronic device includes a fin stack that is thermally coupled to the aforementioned thermal components, and further receives air driven in by the air mover(s). Also, the electronic device is designed to receive the ambient air through openings that define a 360-degree air inlet.

    Abstract: An assembly for heat-generating components includes a metal and a non-metal layer. To secure to a circuit board that carries a heat-generating component, a metal standoff is secured on a perimeter of the circuit board. Multiple protruding elements of the metal layer of the assembly secure within a respective opening of the standoff. The assembly secures, through metal-to-metal contact, to the standoff by multiple mechanical couplings. The assembly not only covers the circuit board, but also extends laterally beyond the circuit board (and the circuit board components). As a result, the assembly receives thermal energy from a heat-generating component(s) on the circuit board and allows the thermal energy to flow through assembly from one portion of the assembly covering the heat-generating component(s) to the lateral portion of the assembly that does not cover the heat-generating component(s).
