A Parametric Study of Magnet System Topologies for Miniature Loudspeakers

Document Thumbnail

This paper presents an overview of the results of a parametric study on miniature loudspeaker (‘microspeaker’) designs. It compares a specific microspeaker design with fixed outer dimensions in 3 different electrodynamic magnet system topologies, namely the centermagnet, ringmagnet, and doublemagnet configurations. The study results are derived from simulations of the Bl-factor, moving mass and effective radiating area with the voice coil inner diameter being the independent variable. Sound pressure level, electrical quality factor, and resonance frequency in a closed box were calculated and used to create easily understandable charts comparing the 3 topologies.
