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 mechanical behaviour of thin perforated plates and their application in silicon condenser microphones
In this paper an alternaUve approach to the modelling of plates with a large number of holes is pres;nted. By means of plate theoPy, it is shown that perforated plates can be modelled by conventional orthouopic plates with modified elastic preponies. The modification of the elastic constants is derived by equalizing the strain-energy oftbe perforated and the ortholropic plate. The model oblaine...
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...
متن کاملElectrode surface profile and the performance of condenser microphones.
Condenser microphones of all types are traditionally made with a planar electrode parallel to an electrically conducting diaphragm, additional diaphragm stiffness at acoustic frequencies being provided by the air enclosed in a cavity behind the diaphragm. In all designs, the motion of the diaphragm in response to an acoustic signal is greatest near its center and reduces to zero at its edges. A...
