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 can provide both thermal mitigation and structural stability. The passive thermal-control structure can conduct heat from the electronic subsystems to a housing of the electronic speaker device.

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: This application is directed to a method for correct temperature measurement. An electronic device includes a temperature sensor that measures an ambient temperature of an environment and a display that is driven by a display driver. The electronic device determines a brightness setting of the display, estimates a display driver current based on the brightness setting, estimates a driver efficiency of the display driver based on the display driver current, and combines a predetermined display driver voltage, the display driver current, and the driver efficiency to determine a power consumption of the display driver. An ambient temperature correction is determined in accordance with the determined power consumption of the display driver, and the measured ambient temperature is thereby corrected using the ambient temperature correction. In some implementations, a power consumption of a distinct heat-generating electronic component is also monitored for adjusting the ambient temperature correction.

Abstract: This document describes a passive thermal-control system that can be integrated into an electronic speaker device and associated electronic speaker devices. The passive thermal-control system uses an architecture that combines heat spreaders and thermal interface materials to transfer heat from heat-generating electronic devices of the electronic speaker device to a housing component of the electronic speaker device. The housing component dissipates the heat to prevent a thermal runaway condition.
