Description

Class 155 0.02mm Super thin enameled copper wire for voice coils

Ultra-thin enamelled copper wire is commonly used in audio equipment and diaphragm drivers in voice coils.

Voice coils are an important component of devices such as speakers and headphones, which produce sound vibrations by generating electric current in a magnetic field.

Ultra-thin enameled copper wire can provide high sensitivity and response speed due to its thin and dense insulation layer, making it one of the ideal materials for voice coils. It has the characteristics of good electrical conductivity, small size, light weight, and high mechanical strength, and can be used to manufacture high-performance voice coil components.

In audio equipment, the application of ultra-thin enameled copper wire helps improve audio accuracy and sensitivity, while also enabling a lighter and more compact design. This material can meet the requirements of audio equipment for high-quality sound and complex vibration drive, so it has been widely used in voice coils.
