摘要：
A loudspeaker protection system includes a filter arrangement for defining one or more frequency bands of an audio signal, controllable amplifier/attenuator combinations coupled to the filter arrangement, and a processing arrangement coupled to control the amplifier/attenuator combinations, such as to determine audio power in at least one of the frequency bands representing relevant loudspeaker protection information used for selective audio power control in the at least one frequency band. This system has the features for a fast and/or slow thermal protection, as well as for a cone excursion protection, all for a loudspeaker in such a system.
