  • Patent number: 11871203
    Abstract: A method for controlling a loudspeaker having an electromechanical force transducer and a diaphragm by: Providing a non-linear electromechanical model configured to apply one or more desired conditions to a loudspeaker input digital audio signal, i.e. to an analogic input signal converted in a digital input signal; Providing an inverse non-linear electromechanical model of the transducer configured to receive a signal processed by the non-linear model and to linearize at least one mechanical and/or electrical and/or electromechanical non-linearity of the transducer; Converting the digital output signal of the electromechanical model into an analog signal for the transducer, So that the output signal comprises an input voltage signal for the transducer and at least the second non-linear model is a digital wave filter (hereinafter referred to as Wave Digital Filters, WDF) to provide a directly computable function in the discrete-time domain to get the input voltage signal for the transducer.
