Abstract
The compliance of the loudspeaker suspension is known to depend on the recent excitation level history.
Previous investigations have shown that the electrical power as well as displacement and velocity plays a
role. In this paper the hypothesis that the changes in compliance are caused mainly by how much the
suspension has been stretched, i.e. the maximum displacement, is investigated. For this purpose the changes
in compliance are measured when exposing the speaker to different levels and types of electrical excitation
signals, as well as mechanical excitation only. For sinusoidal excitation the change in compliance is shown to
depend primarily on maximum displacement. But for square pulse excitation the duration of the excitation
also plays an important role
