Where I live I hear these beetles making a rattle noise. And we all know snakes. I can hear the beetles now. It's beautiful.
What kind of noise? Hum/click/rattle/knock/squeal?

The rattle is used as a warning. Most animals are afraid of something they don't understand. The noise the rattle makes is not a 'normal' noise - most animals are startled by the noise, and leave the snake alone.
you may have a loose clamp holding it. You could have a rock in it.
Many different non venomous snakes will rattle their tails against leaves and dry grass to make a "rattle" noise to try to fool an potential predator. Making this noise will possibly fool an animal or person into thinking it is a rattlesnake.
They have rough skin they are really scary they have a tail that makes noise.
