Modelling of silicon condenser microphones
Several models concemmg the senslhvlty of capaclhve pressure sensors have been presented m the past Modellmg of condenser nucrophones, which can be constdered to be a specml type of capacltlve pressure sensor, usually reqmres a more comphcated analysis of the senstttvlly, because they have a strong electnc field m the atr gap It IS found that tbe mechamcal sensltlvlty of condenser rmcrophones ~...
متن کاملModelling distortion in condenser microphones
Preface In the scope of my studies at the Technical University of Denmark (DTU) in the Engineering Acoustics master program, I have done my final project about modelling distortion in condenser microphones. This subject was originally proposed by Brüel & Kjaer Sound & Vibration Measurement A/S (B&K) under the title Distortion process in condenser microphones. In February 2009 I have started my ...
متن کاملOn the Electromechanical Behaviour of Thin Perforated Backplates in Silicon Condenser Microphones
In this work an alternative approach to the modelling of plates with a large number of holes, is presented. By means of plate theory, it is shown that perforated plates can be modelled by conventional orthotropic plates with modified elastic properties. The modification of the elastic constants is derived by equalising the strain-energy of the perforated and the orthotropic plate. The model obt...

15 صفحه اولHybrid method for determining the parameters of condenser microphones from measured membrane velocities and numerical calculations.
Typically, numerical calculations of the pressure, free-field, and random-incidence response of a condenser microphone are carried out on the basis of an assumed displacement distribution of the diaphragm of the microphone; the conventional assumption is that the displacement follows a Bessel function. This assumption is probably valid at frequencies below the resonance frequency. However, at h...
