A comprehensive circuit model for the electromechanical/Acoustic transducer

A comprehensive circuit model is derived for the electromechanical transducer using an electromagnetic gyrator to link the electric and the magnetic circuits and a magnetomechanical gyrator to link the magnetic and the mechanical circuits. The unified model permits evaluation of the effect of the system parameters on overall operation, particularly the parameters of the magnetic circuit. The loudspeaker is discussed as a particular example although the theory can he extended to other electromechanical devices.
