Abstract

Method for forming compact electric coils having a high fill factor, such as mobile loudspeaker coils, in which the coil consists of an insulated conductor winding of circular section, characterized in that the coil, after being wound, is maintained or mounted on a core that occupies it internally, after which it is subjected to a treatment consisting of radially compressing the winding layers until the conductor surface of each winding is deformed substantially flat in the areas that have been compressed against the surfaces of the adjacent conductor portions of the adjacent windings.
