Abstract
Described is a unit for amplifying and processing audio signals for driving an electro-acoustic transducer (D), comprising: an input for audio signals; a processor for audio signals (107); an output for a signal for driving said electro-acoustic transducer; and an input for at least one operating quantity of the electro-acoustic transducer. The audio-signal processor is programmed for setting a series of parameters defining a transducer to be emulated, the parameters of which define a model of the transducer to be emulated. The input audio signal is processed on the basis of said at least one operating quantity of the electro-acoustic transducer to obtain a behavior of the electro-acoustic transducer that emulates the transducer defined by said series of parameters set.

An audio signal amplifying and processing unit, comprising:
- an audio signals processor receiving audio signals and a differential-pressure signal as input, said audio signals processor providing an electro-acoustic transducer signal as output for driving an electro-acoustic transducer, said differential-pressure signal corresponding to a differential pressure between a pressure of a front space of the electro-acoustic transducer and a pressure of a rear space of the electro-acoustic transducer, wherein the differential-pressure signal is processed by said audio signals processor for correcting any possible distortions and incongruities regarding the reference acoustic system via variation of the electro-acoustic transducer signal for driving the electro-acoustic transducer.
An amplification system comprising:
- an electro-acoustic transducer comprising a front surface, a rear surface and a differential pressure sensor associated with said electro-acoustic transducer, said front surface and said rear surface defining a front volume and a rear volume, said differential pressure sensor detecting a differential pressure based on a pressure in said front volume and a pressure in said rear volume, said pressure sensor providing a differential-pressure signal as output, said differential-pressure signal corresponding to said detected differential pressure;
- an audio signal amplifying and processing unit comprising:
- an input for audio signals;
- an audio signals processor;
- an output for a signal for driving an electro-acoustic transducer;
- and
- an input for receiving said differential-pressure signal, wherein the differential-pressure signal is processed by said audio signals processor for correcting any possible distortions and incongruities regarding the reference acoustic system via variation of the signal for driving the electro-acoustic transducer, wherein said audio signal amplifying and processing unit is connected to said electro-acoustic transducer, said differential-pressure signal being processed for correcting any possible acoustic distortions via variation of the output signal of the audio signal amplifying and processing unit.
