Headphone drivers operate on the principle of electromagnetism. They consist of a diaphragm connected to a voice coil, which is suspended in a magnetic field.

When an electrical signal is passed through the voice coil, it creates a magnetic field that interacts with the permanent magnet, causing the diaphragm to vibrate and produce sound waves.

Dynamic vs. Planar Magnetic Drivers

Two common types of headphone drivers are dynamic and planar magnetic drivers.

Dynamic drivers are the most common type, known for their robustness, affordability, and ability to produce strong bass. They use a cone-shaped diaphragm attached to a voice coil. While dynamic drivers are versatile, they may not always offer the same level of detail and clarity as planar magnetic drivers.

Planar magnetic drivers use a thin, flat diaphragm suspended between magnets. This design allows for more uniform movement and lower distortion, resulting in more accurate and detailed sound reproduction. Planar magnetic drivers are often preferred by audiophiles for their superior sound quality, particularly in terms of clarity and imaging.

Driver Size: Impact on Sound Reproduction

The size of the headphone driver can also influence its performance. Larger drivers are generally capable of producing more bass and higher sound pressure levels (SPL). However, larger drivers can also be more difficult to control and may introduce distortion at higher frequencies.
