Abstract:
A system may comprise a speaker in a speaker tube; a directional tube having a proximal end openly connected to the speaker tube; a first plate having an opening aligned with a distal end of the directional tube; a diaphragm in a spaced apart relationship with the first plate such that an air enclosure is formed between the diaphragm and the first plate, wherein the air enclosure, the directional tube, and the speaker tube cooperate to form a static-air space such that air pressure changes in the space produced by the at least one speaker move the diaphragm; a second plate in a spaced apart relationship with the diaphragm such that a gas enclosure is formed between the diaphragm and the second plate; wherein movement of the diaphragm moves gas in the gas enclosure through the second plate thereby modulating flames above the second plate when the gas is ignited.
