Passive thermal-control structure for speakers and associated apparatuses and methods

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.

A heat generating component is mounted on a circuit board housed and fixed in a case including a base and a cover. Heat generated from the circuit board is transferred from a back surface of the circuit board via an insulating sheet to a heat transfer base portion formed on an inner surface of the base. Protruding portions configured to press the circuit board through elastic bodies are formed on an inner surface of the cover. When a peripheral portion of the circuit board is in pressure contact with and sandwiched between base-side and cover-side hold portions, curvature deformation of the peripheral portion of the circuit board occurs in a downward direction. Before start of the curvature deformation, the elastic bodies are brought into abutment against a front surface of the circuit board to suppress a reduction in pressure contact force on the insulating sheet.
