Abstract: An integrated amplifier and speaker system is disclosed which is designed to use air waves produced by the excursion of the speaker diaphragm together with a heat sink for maintaining the temperature of the power transistors within a safe operating range at or below a desired maximum temperature level. By integrally designing the speaker and the amplifier, the increase in cooling capability provided by the speaker diaphragm excursion allows for the use of a heat sink having an area or heat dissipating capability lower than that required had the system not been integrally designed.
