<p>Disclosed is an inside winding voice coil that can effectively resolve the problems of existing coils rubbing against the magnetic circuit and causing heat damage after extended use, or the magnetic circuit being pulled apart. The inside winding voice coil comprises a winding and a former, the former is provided with a through-hole and at least one coil is arranged in the through-hole. The advantages of the present invention are: when the coil plays high power music, the former is on the outside of the winding, limiting the expansion of the winding to a certain extent. Even if rubbing with the magnetic circus is inevitable, it would be the former that rubs against the magnetic circuit, thus ensuring the reliability of the coil and prolongs the service life of the coil.</p> |
