voice coil

**voice coil**

A voice coil is a crucial component in loudspeakers and headphones that converts electrical signals into sound. It consists of a coil of wire attached to the speaker cone, placed within a magnetic field. When an audio signal passes through the coil, it creates a varying magnetic field that interacts with the permanent magnet, causing the coil and cone to move. This motion produces sound waves that we hear. Understanding how voice coils work is essential for anyone interested in audio technology and speaker design.
