A sound engine comprising a firing chamber, an output horn, an igniter, a valve system, an electromagnetic control device, and a source of electrical signal impulses. The igniter is mounted about the firing chamber. The valve system is arranged generally adjacent the firing chamber for permitting the controlled separate introduction of fuel and air into the firing chamber. The valve means comprises a source of fuel, a source of air, a fuel shuttle valve, and an air valve. The fuel shuttle valve and the air valve are integrally connected. The electromagnetic control device is connected to the valving system for causing movement of the valving system in response to electrical signal impulses. The electromagnetic control device includes voice coils, magnetic field windings, and a housing. An output area occurs relative to the firing chamber to permit sound output from the firing chamber. The output area includes suitable mounting flanges for attaching horns thereabout.
