Non-linear Loudspeaker Unit Modelling

Bo Rohde Pedersen, Finn T. Agerkvist

    Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review


    Simulations of a 6½-inch loudspeaker unit are performed and compared with a displacement measurement. The non-linear loudspeaker model is based on the major nonlinear functions and expanded with time-varying suspension behaviour and flux modulation. The results are presented with FFT plots of three frequencies and different displacement levels. The model errors are discussed and analysed including a test with loudspeaker unit where the diaphragm is removed.
