How static speakers work

Electrostatic loudspeaker is to use the electrostatic power added to the capacitor plate and the loudspeaker work, in terms of its structure, because the positive and negative poles are opposite and into the capacitor shape, so it is also called capacitor loudspeaker. Loudspeaker as an electroacoustic transducer, we have to start from the human understanding of electricity and sound conversion relations. Electromagnet sounds have been used since 1837 Page. But it was not until February 14, 1876, when Alexander Graham Bell filed one of the most important patents in history: the "telephone," an invention that allowed the human voice to travel farther than a shout. Since then, the conversion relationship between electricity and sound has been deeply rooted in the hearts of people, and more and more people have studied it.
