Condenser Microphone, Axisymmetric with Electric Lumping

This model is that of a simple axisymmetric condenser microphone. The model includes all the relevant physics and determines the sensitivity of the specific microphone geometry and material parameters. The model uses a lumped approximation for the electric small signal problem but solves a full FE model for the acoustic-mechanical system. The quiescent (zero point) problem is solved fully using electrostatics and a membrane model.



The model includes:

1. Thermoacoustics for the acoustics at this small scale
2. A PDE model of a tensioned membrane
3. Moving mesh to deform the geometry
4. Electrostatics to determine capacitance
5. Circuit model to model electric lumped model (small signal analysis)
