声音系统设备.电声变换器.悬吊部件的动态测量

[中文适用范围]： 本PAS适用于电声换能器（例如扬声器）的悬挂部件。它定义了参数和测量方法，以确定悬架部件（如星形轮、环绕件、隔膜或锥体）在组装到传感器中之前的刚度。测量结果用于工程设计目的和质量控制。此外，该方法旨在提高悬架部件制造商和扬声器制造商之间测量的相关性。该测量方法基于线性模型提供有效刚度 Keff，并使用非线性模型提供刚度变化 K(x) 与位移 x 的关系。这两个参数都是通过激励悬架部件产生机械振动来动态测量的。 [外文原描述]： 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
