Hi Guys
I'm trying to experiment with the most simple amplifier. (A transistor,
couple of resistors and maybe one or two caps).
For now I was just trying to see if the mic is working but I didn't
have any success. I used my computer's headset mic but I don't know if
it is dynamic or electret. So far I was unable to get ANY signal from
the mic (I know it is working on the PC). It will be nice if someone
can point to me to Maplin.co.uk parts if I need any.
Can someone please give me some guidance as to what I need? I prefer a
dynamic mic because it seems simpler. Also is there some web source
that describes everything from mic to speaker (preferable showing
waveforms)
So far the best resource I have is:
http://www.tpub.com/content/neets/14179/css/14179_77.htm
but unfortunatly it doesn't show the whole process from MIC to speaker.
Does a speaker need positive and negative voltage or if your soundwave
goes from 0 to 10V e.g. will still be able to be played over the
speaker?
Thanks in advance for any tips / links
