The Science of Sound: How Headphones Deliver Audio

Now that we’ve explored the wonders of Bluetooth 5.3, let’s delve into the core of any headphone experience: the sound itself. Headphones, at their heart, are miniature loudspeakers designed for personal listening. They transform electrical signals into sound waves that our ears can perceive.

Dynamic drivers, the most common type used in headphones, including many contemporary models, operate on the principle of electromagnetism. A dynamic driver consists of three key components:

1. A diaphragm: A thin, lightweight membrane that vibrates to produce sound waves.
2. A voice coil: A coil of wire attached to the diaphragm.
3. A magnet: A stationary magnet that creates a magnetic field.

When an electrical audio signal passes through the voice coil, it generates a fluctuating magnetic field. This field interacts with the permanent magnet’s field, causing the voice coil, and consequently the diaphragm, to vibrate. These vibrations create pressure waves in the air, which we perceive as sound. The size of these dynamic drivers influence sound quality; generally speaking larger drivers, such as the 13mm drivers used in some modern headphones, can displace more air, often resulting in a richer bass response and a wider soundstage.
