Electrostatic speakers are a type of loudspeaker that use electrostatic principles to produce sound. They consist of a thin, electrically charged diaphragm placed between two conductive panels. When an audio signal is applied, the diaphragm moves in response to the varying electric fields, creating sound waves. These speakers are known for their clarity and detail, often providing a more accurate reproduction of music compared to traditional dynamic speakers. However, they typically require a special amplifier and can be more expensive, making them a popular choice among audiophiles who prioritize sound quality.
