Current research into electroacoustics tends to determine the global transfert function between an initial electrical signal and the acoustical signal supplied at the ear. Because electrodynamic transducers radiate in a large frequency bandwidth, lumped parameter model such as Thiele and Small's is not sufficient to provide a realistic simulation of the vibro-acoustic behaviour of the system. This study proposes the use of Finite Element and Boundary Element Methods to compute a complex 3D response of a loudspeaker for each mechanical modes and then synthesize an equivalent electrical model that takes into account acoustical coupling between all modes.
