適用范圍：This International Standard applies to transducers such as loudspeaker drive units,loudspeaker systems, headphones, micro-speakers, shakers and other actuators using eitheran electro-dynamical or electro-magnetic motor coupled with a mechanical suspension. Thelarge signal behaviour of the transducer is modelled by a lumped parameter modelconsidering dominant nonlinearities such as force factor, stiffness and inductance as shown inFigure 1. The standard defines the basic terms and parameters of the model, the methods ofmeasurements and the way the results should be reported.
