标准摘要
[中文适用范围]: 本标准适用于完全作为无源元件处理的声系统扬声器。内置放大器的扬声器不包括在内。 注 1:本标准中使用的术语“扬声器”既指扬声器驱动单元本身,也指由一个或多个扬声器驱动单元组成,并配有障板、箱体或号角,以及内置分频器、变压器等任何相关无源元件的扬声器系统。 本标准的目的是给出扬声器使用正弦波或指定的噪声或脉冲信号时应规定的特性及相关测量方法。 注 2:本标准中给出的测量方法是根据其适用性选择的。 注 3:如果使用其他测量方法能获得等效结果,应提供所用方法的详细信息。 注 4:以下项目正在考虑中: - 内置放大器的扬声器; - 除自由场、半空间自由场和扩散场以外的条件下的测量; - 除正弦波、噪声或脉冲信号以外的信号的测量。 [外文原描述]: IEC 60268-5:2003+A1:2007 applies to sound system loudspeakers, treated entirely as passive elements. Loudspeakers with built-in amplifiers are excluded. It gives the characteristics to be specified and the relevant methods of measurement for loudspeakers using sinusoidal or specified noise or impulsive signals. This third edition cancels and replaces the second edition published in 1989, amendment 1 (1993) and amendment 2 (1996). It constitutes a technical revision. This publication is to be read in conjunction with IEC 60268-1:1985 and IEC 60268-2:1987 This consolidated version consists of the third edition (2003) and its amendment 1 (2007).
