I'm using a speaker to output a few PWM signals.
I got the speaker from taking apart some cheap computer speakers.
When I feed in my PWM output directly to the speaker, the sound that is generated doesn't seem to be loud enough. Is there a way to amplify that using simple circuitry? Any sample circuitry I could refer to would also help. Thanks a lot

Any computer speakers for use with ATX boards already have an amplifier inside (as the motherboard doesn't have power amplifiers on board). If your speaker has one, use that!.
