IEC 62458:2010适用于换能器，例如扬声器驱动单元、扬声器系统、耳机、微型扬声器、振动器和其他使用与机械悬架耦合的电动或电磁马达的致动器。换能器的大信号行为由集中参数模型建模，该模型考虑了主要的非线性，如力因子、刚度和电感。它定义了模型的基本术语和参数、测量方法以及报告结果的方式。它取消并取代了2006年发布的IEC/PAS 62458。它构成技术修订。主要变化有: -测量方法的描述被调整到技术的状态； -增加第4至15条； -将附件A纳入标准的主体； -整体文本审查。

IEC 62458:2010 applies to transducers such as loudspeaker drive units, loudspeaker systems, headphones, micro-speakers, shakers and other actuators using either an electro-dynamical or electro-magnetic motor coupled with a mechanical suspension. The large signal behaviour of the transducer is modelled by a lumped parameter model considering dominant nonlinearities such as force factor, stiffness and inductance. It defines the basic terms and parameters of the model, the methods of measurements and the way the results should be reported. It cancels and replaces IEC/PAS 62458 published in 2006. It constitutes a technical revision. The main changes are:
- descriptions of the methods of measurement are adjusted to the state of the technology;
- addition of Clauses 4 to 15;
- integration of Annex A in the main body of the standard;
- overall textual review.
