IEC PAS 62459:2006 声音系统设备.电声变换器.悬吊部件的动态测量

This PAS applies to the suspension parts of electroacoustical transducers (for example, loudspeakers). It defines the parameters and measurement method to determine the stiffness of suspension parts like spiders, surrounds, diaphragms or cones before being assembled in the transducer. The measurement results are needed for engineering design purposes and for quality control. Furthermore, this method is intended to improve the correlation of measurements between suspension-part manufacturers and loudspeaker manufacturers. The measurement method provides the effective stiffness, Keff, based on a linear model and the variation of the stiffness, K(x), versus displacement x using a non-linear model. Both parameters are measured dynamically by exciting the suspension part to mechanical vibrations.

IEC PAS 62458:2006 音响系统设备.电声换能器.大信号参数测量

This PAS applies to transducers such as loudspeakers, headphones, shakers, and other actuators using either an electro-dynamical or electro-magnetic motor coupled with a mechanical suspension. The measurement results are needed for engineering design purposes and for quality control. The measurement method provides the parameters of a non-linear large signal model (as shown in Figure A.1) which describes the effect of the dominant non-linearities inherent in those transducers. The basic terms and measurement conditions are defined for static and dynamic methods.
