5 Σεπ 2019 · At its simplest, a plasma speaker circuit consists of two electrodes and a power supply. The electrodes are connected to the power supply, which creates an electrical arc between them. This arc causes the air in between the two electrodes to become ionized, forming a column of plasma.
The Plasma Speaker: Are you tired of those old black speakers that only just make sounds? Maybe sound reactive lights are just not enough to impress you? How about a Plasma Speaker? A plasma speaker is a device that generates an high voltage electrical arc that make…
The type of speaker designed and investigated in this paper is the AC arc plasma speaker. There are two sub-types of AC plasma speakers - fixed arcs and Tesla type arcs. Plasma speakers with fixed arcs have two electrodes at a set distance apart and the arc forms between these two electrodes as shown in figure 1.
The plasma speaker works by using a changing generation of heat to modify the vibrations. To build the speaker, we need to drive a flyback transformer with a music signal. In other words, our transformer needs to receive power relative to the music signal.
The circuit diagram is shown in Figure 2. The basic concept driving the plasma speaker is relatively simple; a square wave is modulated and applied to the transformer to generate varying voltage pulses.
Plasma Speaker DIY: This instructable will show you how to build a 555 timer driven plasma speaker that can play music from any device with a headphone jack. It will go through the materials, circuit diagram, and how to make it.
So what is a plasma speaker? A plasma speaker (aka “singing arc”) is a speaker that uses a plasma arc to produce sound. By varying the intensity of the arc, different pressure waves are created.
