WonderTone produces electronically synthesized sounds.
WonderTone works soley on the kinetic energy of the users
and can be operated by one or two players. A hand-crank
powers the musical instrument. The sound is controlled by
movement of a player's hand over a flat antenna. The hand
motion in mid-air produces a continuous range of tones.
These unique sounds are heard from a small internal
loudspeaker which faces the players.
WonderTone can be installed indoors or outdoors and
is weather and vandal resistant. The electronic components
were designed to withstand a broad rangeof temperature and
humidity and are easily accessed for simple, periodic calibrations.
