Abstract: This paper investigates the creep effect, the visco elastic behaviour of loudspeaker suspension
parts, which can be observed as an increase in displacement far below the resonance frequency.
The creep effect means that the suspension cannot be modelled as a simple spring.
The need for an accurate creep model is even larger as the validity of loudspeaker models are
now sought extended far into the nonlinear domain of the loudspeaker.
Different creep models are investigated and implemented both in simple lumped parameter
models as well as time domain non-linear models, the simulation results are compared
with a series of measurements on three version of the same loudspeaker with different
thickness and rubber type used in the surround.
