Handheld devices such as smartphones, tablets, etc. can be placed on a charger/speaker dock that provides battery charging and also enables enhanced audio output via speakers integrated into the dock. A device docked on the charging/speaker dock generates heat, which can trigger the slowdown or halting of charging and capping of the audio gain of the speaker. This disclosure describes techniques to improve heat dissipation and prevent overheating of a docked device by optimizing the geometry of the charger/speaker dock; optimizing the placement of heatsinks; optimizing the relative positions of the speaker, the printed circuit board, and the faceplate of the charger/speaker dock; throttling the charging current or the audio volume in response to a measured temperature; incorporating a heat pipe or phase-change materials to transfer heat from hot components to the heatsink; transferring audio processing from handheld device to dock; etc.
