标准摘要
[中文适用范围]： 范围和目标 本国际标准适用于被视为完全无源电声换能器元件的发声器@。压电振膜@是压电发声器@的主要部件。作为内置电路的声源的蜂鸣器除外。本标准的目的是标准化与这些电声换能器相关的定义，并列出要指定的特性和相关测量方法。 [外文原描述]： Applies to sounders which are treated as entirely passive electroacoustic transducer elements. Piezoelectric diaphragms, which are the principal components of piezoelectric sounders, are also included. Standardize the definitions relating to these electroacoustic transducers, lists characteristics to be specified and the relevant methods of measurement.
英文名称Sound system equipment - Methods of measuring and specifying the performance of sounders (electroacoustic transducers for tone production)
