Why does touching the jack of my speaker make noise ?

When I touch the 3.5mm jack of my speaker, it makes noise. Why ?

basically when you touch the tip, you are completing what is called an electric circuit, with your body as the bridge between the cable to the ground. The jack picks up the natural electricity your body produces, which is what creates the buzz.
