Sound and power go hand in hand.
When we design our vibrators, our challenge is to get the most power with the least sound. Obviously, most people prefer their vibrators quiet, so as not to ruin the mood (or alert your neighbors of your activities), which is why we have a line of vibrators that are nearly silent.
However, Swiss artist Zimoun, uses motors, similar to the ones found inside Jimmyjane vibrators, to play with sound. It is not the motors themselves that make sound, but the objects to which they are attached.
Have a look at some of his Sculpting Sound work. Try closing your eyes while listening – what do you envision?
