Non-uniform Voice Coil Winding for Electrodynamic Loudspeaker

Document Thumbnail

In electrodynamic loudspeakers the force factor Bl is an irregular and asymmetrical function of the voice-coil displacement. This results in diverse distortion during voice-coil oscillation. In the paper a method of artifact reduction is suggested. This method is based on application of non-uniform voice-coil winding, i.e. number of layers varies along the voice-coil axis. The voice coil proposed allows a more regular and symmetrical Bl factor than a conventional voice coil. Theoretical background of the method is given. Effects of the non-uniform voice coil on loudspeaker performance have been investigated using Klippel Distortion Analyzer.
