A voice coil is a flat coil composed of conductive coils, commonly used in audio equipment such as electric speakers, headphones, and speakers. When the voice coil is driven by a current signal, it vibrates and pushes the diaphragm connected to it, producing sound.
The material and structure of voice coils have a significant impact on their performance and lifespan. Common voice coil materials include copper, aluminum, nickel, etc. Among them, copper is the most commonly used material. The winding method of the voice coil can also affect its performance, such as the winding methods of different shapes such as circular, elliptical, and flat.
During the manufacturing process, the voice coil needs to undergo precise processing and adjustment to ensure its performance and lifespan. For example, the number of turns, wire diameter, winding method, etc. of the voice coil need to be precisely calculated and adjusted according to design requirements.
In short, voice coils are an important component of audio devices, and their performance and quality have a direct impact on the sound quality and performance of audio devices.
