Abstract
An audio appliance includes an oscillatable diaphragm, a first heat-dissipation unit, a second heat-dissipation unit, and a control unit. The first heat-dissipation unit dissipates heat at a first rate and the second heat-dissipation unit dissipates heat at a second rate. The control unit can receive an indication of a temperature of the first heat-dissipation unit and an indication of a temperature of the second heat-dissipation unit. The control unit provides oscillation control of the oscillatable diaphragm to maintain the temperature of the first heat-dissipation unit below a first threshold and/or to maintain the temperature of the second heat-dissipation unit below a second threshold. The control unit can provide the oscillation control responsive to each of the indication of the temperature of the first heat-dissipation unit and the indication of the temperature of the second heat-dissipation unit exceeding a respective threshold.
