This project aims to develop a singing arc. A singing arc is commonly, though mistakenly, referred to as a plasma speaker. Whereas a traditional speaker uses a pulse width modulated (PWM) signal to move an electromagnet, which in turn moves a cone, which generates sound waves, the singing arc sends a PWM signal through a standing spark, which vibrates, which generates sound waves.

Several plans for the singing arc are readily available online. This project will analyze the similarities between a selection of them, try to eliminate any faults in design, and improve the function of the circuit. The final end goal will be to present a functional device. Since the components necessary to build a singing arc are readily available and affordable, but a similar product is not currently mass produced for consumption, there must be legal and environmental issues concerning a device of this nature, other than the obvious risk of electrocution. These issues will be researched and addressed as well, and included with the final project report.
