测量传声器.第6部分:频率响应的测定用静电致动器

[中文适用范围]： IEC 61094 的这一部分 - 为配备导电隔膜的麦克风执行器的设计提供指南； - 给出静电致动器的验证方法； - 给出了确定静电作用的方法 [外文原描述]： This part of IEC 61094 - gives guidelines for the design of actuators for microphones equipped with electrically conductive diaphragms; - gives methods for the validation of electrostatic actuators; - gives a method for determining the electrostatic actuator response of a microphone. The applications of electrostatic actuators are not fully described within this standard but may include - a technique for detecting changes in the frequency response of a microphone, - a technique for determining the environmental influence on the response of a microphone, - a technique for determining the free field or pressure response of a microphone without specific acoustical test facilities, by the application of predetermined correction values specific to the microphone model and actuator used, - a technique applicable at high frequencies not typically covered by calibration methods using sound excitation.
