Motion sensor audio device

Hi. I wanted to make a device that would play a piece of audio that I recorded when I trigger some sort of motion sensor. I don't know what parts I would actually need as far as a motion sensor, a record/playback device, or other misc parts. I have a fair understanding of resistors and voltage but I'm pretty much a beginner. If anyone could point me in the right direction, that would be well appreciated.

Well, a basic understanding of motion dection can be gotten from this link. and one solution for the "play back" is for your sensor to trigger a digital rec. / playback circuit like this one
