pressure microphone

基本解释

Additional electronics have been added to provide film heating for calibration and to amplify the signal from the head's microphone pressure sensor.
附带的电子器件可增加校准时的薄膜加热功能和放大从探头的扩音压力传感器输出的信号。
A microphone detects those sounds by means of a membrane or diaphragm inside it that vibrates in response to the pressure waves of sound that reach it.
水听器可侦测这些声音正是通过其内部的薄膜或振动膜反应触及它的声波压力。
Air pressure on the surface of the Earth is fairly constant, so in designing a microphone for use on land, engineers don't have to worry about large variations in air pressure.
地球表面的气压相对稳定，因此设计地面用的传音器，工程师并不需烦恼气压的大幅变化。
