Plasma speaker - audio modulated electric arc
Klein, Ondřej ; Červinka, Dalibor (referee) ; Martiš, Jan (advisor)
The bachelor thesis deals with design and realization of electric arc modulated by audio signal. It is also known as plasma speaker. Absence of any mechanical components gives membranless speaker no frequency limitation. The design consist of single circuits as power sources for power and control section, control electronics, which modulates the signal, and power section, which reproduce signal in form of sound.
