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.
