Technical Field

The utility model relates to the technical field of voice coil production, in particular to a headphone voice coil winding device.

Background Art

The voice coil is directly defined as the coil through which the current passes. It is an important part of the mechanical wave system of the electrodynamic speaker and can be said to be the heart of the speaker. The performance of the voice coil will affect the sound intensity characteristics, sound intensity level, impedance curve, distortion, transient characteristics, speaker parameters, sound quality, etc. of the speaker, especially the power handling and life of the speaker. Just like the fatal factors of heart disease, the damage of the speaker often starts from the voice coil. When producing the voice coil, a winding device is needed to wrap the copper wire around the outside of the frame.
