Commonly used materials for loudspeaker suspensions have been shown to have viscoelastic properties, best known is the “creep” effect. This phenomenon, while known, is normally of little interest because it is primarily a dc issue outside of the audio frequency range. However, this viscoelasticity phenomenon also has a frequency-dependent influence on damping and compliance. Because damping is inversely proportional to frequency, a simplified model only including frequency-dependent damping is presented. The model provides an acceptable fit for empirical data.
