The headphone driver unit is a device used to convert electrical signals into sound. Each earphone uses one or more driver units to generate sound. The types of headphone driver units are mainly divided into dynamic drivers, dynamic iron drivers, and capacitive headphones. The difference lies in its working principle and design.
Dynamic driver is the most common type of headphone driver unit. It consists of a magnet, a coil, and a vibrating film. When current passes through the coil, it generates a magnetic field and pushes or pulls the vibrating film back towards the magnet. The sound generated by this movement will be captured by the ears. Relatively speaking, the cost of dynamic drives is low, but the sound quality has certain limitations and is not suitable for users who pursue high-end sound quality.
The dynamic iron driver is a relatively high-end headphone driver unit. It consists of a curved thin metal sheet, a magnet, and a coil. When current passes through the coil, it causes vibrations in the thin metal sheet, which in turn produces sound. The characteristic of a dynamic iron driver is that it can provide finer sound quality and better response speed, but the price is relatively expensive.
Capacitive headphones are an uncommon type of headphone driver unit. It uses the capacitive effect between two metal plates to generate sound. When current flows through metal plates, they generate electrostatic force, which in turn generates vibration. Capacitive earphones are usually considered to provide cleaner and more natural sound quality, suitable for users with high requirements for sound quality.
In summary, the type and design of the headphone driver unit all affect the sound quality and user experience of the headphones. Users can choose suitable headphones based on their own needs and budget.
