How do those little yellow speakers that come in some cheap mcdonalds toys work?
These are also found in all PCs, it is the part that makes the little beep when the computer turns on. I can make them act like a normal speaker (although the sound isn't that great). They are also found in watches.
They also make a really interesting mic,
They don't seem to make sound the same way a normal speaker does.
I would like to know, since this type of technology interests me, but I can't seem to find any info on them on the internet.
Is there any special setup I would need to make act like a normal speaker? I can hook it up to a cd player, but it isn't very loud and they seem much louder in their native equipment (small toys/computers).
These things can act as a microphone as well, but they detect sound much differently then a normal mic, (which is basicly a really small speaker, but doesn't have all the parts needed to make sound that is audible to the human ear)
They seem to turn anything touching them into a gient mic. They can pick up sound in solid objects (and liquids possibly).But not any sounds that travel through the air.
