Ironless Motor Loudspeaker: Quantization of the Subjective Enhanced Sound Quality
This paper presents a set of measurements realized on two automotive loudspeakers. These two loudspeakers have the exact same moving part and suspensions parts but different motors. The first one is equipped with a traditional production model motor made of ferrite and iron whereas the second one gets a prototype of ironless motor made totally of permanent magnets. Blind listening tests performed with these two speakers showed a significant advantage of perceived sound quality for the ironless motor loudspeaker. Several types of measurements have been realized in order to try to quantify and explain this sound quality enhancement. Results are given in this paper.
