Abstract:
The present invention relates in one aspect to a method of controlling or limiting diaphragm excursion of a loudspeaker. The method comprising steps of receiving a first audio signal and deriving an excursion signal representing diaphragm excursion of the electrodynamic loudspeaker from the first audio signal. The method additionally comprises deriving an excursion envelope from the excursion signal and applying a second audio signal, derived from the first audio signal, to an input of an adjustable low-frequency suppressor. The second audio signal is filtered by the adjustable low-frequency suppressor to selectively attenuate low-frequency components based on the excursion envelope to produce a processed audio signal with reduced low-frequency content.

Claim (Index 13):
A diaphragm excursion limiter for a loudspeaker, comprising:\n an audio signal path extending between an audio input and an audio output, said audio input configured for receipt of a first audio signal, said audio signal path comprising at least an adjustable low-frequency suppressor for receipt and filtering of a second audio signal, derived from the first audio signal; an excursion estimator configured for determining an excursion signal, representing diaphragm excursion of the loudspeaker, based on the first audio signal, a first envelope detector configured for determining an excursion envelope of the excursion signal, a controller configured to adjust a frequency response of the adjustable low-frequency suppressor based on an excursion envelope to selectively suppress low-frequency components of the second audio signal in a processed audio signal at an output of the adjustable low-frequency suppressor.
