本文根据静电激发器校准电容传声器压强灵敏度的原理,导出该法校准精度与各几何量及电学量的关系式。将所测得的全部参量代入运算表明理论值与测量值基本吻合,证明具有可信的绝对校准意义。文中给出修正关系的极限讨论,可用于静电激发器装置的加工与调整时参考。 In this paper, according to the principle of the sensitivity of electrostatic actuator to calibrate condenser microphone pressure, the relation between the calibration accuracy and each geometric quantity and electrical quantity is deduced. Substituting all the measured parameters into the operation shows that the theoretical value and the measured value are in good agreement with each other, which proves to be credible in the meaning of absolute calibration. The paper gives the limit of the revised relationship between the discussion, can be used for electrostatic induction device processing and adjustment reference.
