    Abstract: The present document describes a passive thermal-control structure for speakers and associated apparatuses and methods. The architecture of the passive thermal-control structure is such that heat is transferred from electronic subsystems of the electronic speaker device to the passive thermal-control structure, which acts as an internal, structural frame of the electronic speaker device and provides both thermal mitigation and structural stability. The passive thermal-control structure conducts heat from the electronic subsystems to a housing of the electronic speaker device. The housing of the electronic speaker device may dissipate the heat to the ambient environment to prevent thermal runaway of the electronic subsystems, and the internal frame mitigates the temperature of the housing from exceeding ergonomic temperature limits.

    Abstract: A battery pack includes a battery, a first temperature sensor configured to provide a first temperature value associated with a temperature of the battery, a heat source disposed proximate to the battery and configured to heat the battery, a second temperature sensor configured to provide a second temperature value associated with a temperature of the heat source, and a control board coupled to the first temperature sensor and the second temperature sensor, wherein the control board is configured to receive the first temperature value and the second temperature value. The control board is configured to compare the first temperature value and the second temperature value to determine a temperature gradient between the battery and the heat source and transmit an alert if the temperature gradient exceeds a first temperature gradient threshold.

    Abstract: This document describes a thermal-control system that is integrated into a media-streaming device. The thermal-control system includes a combination of heat spreaders and materials with high thermal-conductivity. The thermal-control system may spread, transfer, and dissipate energy from a thermal-loading condition effectuated upon the media-streaming device to concurrently maintain temperatures of multiple thermal zones on or within the media-streaming device at or below multiple respective prescribed temperature thresholds.

    Abstract: This document describes a reinforced graphite heat-spreader for a surface of a housing component of an electronic device. The reinforced graphite heat-spreader includes a heat-spreader material stack having a layer of graphite material to spread heat. The reinforced graphite heat-spreader also includes an interface material stack that joins the heat-spreader material stack to the housing surface of an electronic device. The interface material stack, which may be formed using embossing techniques, includes protuberances that may be formed from an adhesive material.
