I am trying to build a simple intercom for personal use.
I have built one from the schematic found at ( http://ourworld.compuserve.com/homepages/B...owden/opamp.htm ) ( scroll all the way to the bottom ), but when I speak into the speaker the sound coming out has way too much static and is not understandable at all.
This circuit uses a LM741 chip to amplify the sound. Is there anything I can modify on this circuit to make the sound quality better?
Would I be better off using a LM386 audio amplifier chip and building a completely different circuit?
If so can anyone please give me a link to a schematic that is pretty simple to build but has a very good quality sound coming out! I appreciate it very much.
Thanks
