Top view of the Micronium chip, which sports six tiny mass-spring systems. The colors are caused by an optical effect: the rectangle representing the mass has tiny holes in it, causing reflection of light.
A wafer with a number of chips on it, each chip contains six tiny mass-spring systems and each system produces a different tone

Four chips are placed in a vacuum container and the tones produced are sent to be amplified thousands of times

A Scanning Electron Microscope Image of one single mass-spring system, where the springs, the mass and the moving parts/comb drives can be clearly seen - note the scale
It's much, much smaller than its Stradivarian cousin, but not even the Borrowers, Lilliputians or Blefuscudians are of sufficiently diminutive proportions to take a bow to the Micronium. The tiny instrument is made up of microscopic springs activated by combs to produce an audible tone. Half a dozen tone systems are placed on a chip and then chips combined to offer an orchestral range of sounds.
