"This category [science fiction] excludes rocket ships that make U-turns, serpent men of Neptune that lust after human maidens, and stories by authors who flunked their Boy Scout merit badge tests in descriptive astronomy."
- Robert Heinlein

Chest Disc  
  A voice activated wireless transmitter.  

The chest discs were likewise self-contained sending sets, strapped to the chest a few inches below the neck and actuated by the vibrations from the vocal cords through the body tissues. The total range of these sets was about eighteen miles. Reception was remarkably clear, quite free from the static of 20th Century radios, and of a strength in direct proportion to the distance of the speaker.

Another exceptional idea, particularly the suggestion that the device is voice-activated by sensing vibration from the vocal chords.

This device is part of a set; see the entry for ultraphone ear-disc.
