Planar magnetic technology is a type of speaker design that uses a thin, flat diaphragm suspended between two sets of magnets. This diaphragm is typically made of a lightweight material, allowing it to move freely and produce sound when an electrical signal is applied. The magnetic field created by the magnets interacts with the diaphragm, resulting in high sound fidelity and low distortion. This technology is commonly found in high-end headphones and loudspeakers, offering a unique listening experience. Planar magnetic devices are known for their wide frequency response and detailed sound reproduction, making them popular among audiophiles and professionals in the music industry.
