Product Design: PD4 - Loudspeaker Nonlinear IdentificationPresenter:
Pascal Brunet, Setem Technologies - Newbury, MA, USA
This presentation reviews recent developments in the domain of loudspeaker nonlinear identification and explores new possibilities to improve modeling that is better match to the loudspeaker response. First we present the loudspeaker operation principles and the major causes of distortion, then we explore the successive modeling approaches that have been investigated in the last decades. Finally we provide new directions of research in the frequency domain and propose two techniques based on state-space for modeling of loudspeaker which can effectively be used in identification process.
