Electrostatic loudspeaker is a loudspeaker that works by using the electrostatic force added to the capacitor plate. In terms of its structure, it is also called capacitor loudspeaker because the positive and negative poles are facing each other. As an electroacoustic energy exchange device, we have to start from the understanding of the relationship between electricity and sound.
As early as 1837 page began to use electromagnets to produce sound. But what we really know about the magic of electricity and sound conversion is that on February 14, 1876, Alexander Graham Bell proposed the most important patent "telephone" in history. After that, the invention enables the voice of human beings to be transmitted farther than shouting. Since then, the relationship between electricity and sound has been deeply rooted in people's minds, and more and more people have studied it.
