+ Features about "i-MAJUN"

When using i-MAJUN, a microphone which connected with LED type underwater light picks up the voice of the diver, and the voice is put on the light wave of LED type underwater light to the other diver. The diver who received Visible Light recognizes the received voice from the light wave by bone-conduction speaker. (Because the tympanic membrane in the ear doesn't vibrate in water, the voice is picked up by bone-conduction.)

i-MAJUN can solve the problem of the underwater communication of the past. By a past sound wave method, it was difficult to specify from where voice comes, and to distinguish who was talking to whom. In addition, the sound wave spread far and wide, and occasionally make troubles to the environment or other Buddy. As using i-MAJUN that you can judge visually is an epoch-making technology that makes these problems solved.
