Suspension Creep Models for Miniature Loudspeakers

Authors: Hiebel, Holger

AES Convention 132 · Paper 48 · April 2012

Abstract

Different models for describing the suspension creep behavior of loudspeakers are available at the moment. They include the “LOG”-model from Knudsen, the model used in the Klippel Analyzer system (same as Knudsen, but neglecting the frequency dependent losses) and the 3-parameter model of Ritter and Agerkvist. In contrast to HiFi speakers the differences between the creep models can be seen more clearly in miniature loudspeakers using compound (multilayer) membranes. Benefits from choosing the right creep model are tabulated in terms of RMS fit errors and evaluation results for miniature loudspeaker samples are shown.
