Dynamic Measurement of Loudspeaker Suspension Parameters Using an Active Harmonic Control Technique

Document Thumbnail

A new nondestructive technique to measure the nonlinear suspension parameters (stiffness Kms and mechanical resistance Rms) of a loudspeaker using an active harmonic control technique is presented. The goal of the active harmonic control is to eliminate the higher harmonics from the displacement signal so that a purely harmonic motion of the diaphragm is ensured. The nonlinear stiffness Kms is then measured as a function of instantaneous and peak displacement; the mechanical resistance Rms is measured as a function of velocity. A frequency dependence of these parameters is also discussed.
