Axisymmetric Condenser Microphone
Application ID: 12377
This is a model of a condenser microphone with a simple axisymmetric geometry. The model aims to give a precise description of the physical working principles of such a microphone. The condenser microphone is considered to be the microphone with highest quality when performing precise acoustical measurements and with high-fidelity reproduction properties when performing sound recordings. This electro-mechanical acoustic transducer works by transforming the mechanical deformation of a thin membrane (diaphragm) into an AC voltage signal.
This model is included as an example in the following products:Acoustics Module
however additional products may be needed to reproduce it. This example may be created and run using components from the following product combinations:
- COMSOL Multiphysics® and
- Acoustics Module and
- Structural Mechanics Module and
- either the AC/DC Module, MEMS Module, Plasma Module, or Semiconductor Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille de spécifications and make use of a free evaluation license.
