View Product Description

2UEW155 0.02mm 0.025mm Enameled Coated Copper Wire for Voice Coils

A voice coil is a coil of wire connected to a diaphragm or cone in a speaker. When an audio signal passes through the coil, it interacts with the magnetic field to create sound by moving the diaphragm, or cone, back and forth, creating sound waves.

The voice coil is an integral part of the mechanical structure of the speaker and converts electrical signals into sound.
