Title: Condenser microphone
Post by: reuven on January 12, 2011, 03:05:39 am
Can you make a simulation of a Condenser microphone, that is to show the following variables capacitors sound waves and electrical signal they give. If you can add a change in voltage and change the sound waves, it would be really perfect. Thanks Reuben.

I need more information about the so called condenser microphone.

What is the structure and/or electric curcuit and relation between variables you would like to be simulated (typical value for capitance of the capictor, frequency of the sound wave,... etc.)

I will try to create a simulation for you if I have enough information to create it.

I want to change the frequency, can be less important to change the tension, especially important for me to see the resulting output signal
I added a file from Wikipedia, and his imagery I want really.
Thank you very much.

Could you provide the URL of the wiki-page so that I can find more information?

Look here
http://en.wikipedia.org/wiki/Microphone/
there is also information about, Electret condenser microphone, maybe you can combine them.
These values are very beautiful in German. http://de.wikipedia.org/wiki/Mikrofon.    http://de.wikipedia.org/wiki/Elektretmikrofon

A similar picture can be found at

I tried to read the above web pages, but I can not find the information I need!
Can you provide the relations bewtween, the frequency of the sound wave, voltage, etc.?
I am not an expert in microphone, I need a model in order to create the simulation.

Maybe there's something here
http://hyperphysics.phy-astr.gsu.edu/hbase/audio/mic.html        http://hyperphysics.phy-astr.gsu.edu/hbase/audio/mic2.html#c3
I try to connect with someone who understands microphones, maybe he will give me the model.
