“Inverse Alarm” Clock

This buttonless alarm clock is set by ringing a small gong.

When the gong is hit with the attached mallet, the time begins moving forward rapidly (essentially “set” mode).


As the gong sound gets quieter, the time increase slows down…

until the sound diminishes to nothing or is silenced by the user (returning clock to “display” mode).


I call it an “inverse alarm” clock because the noise it makes is intended for the clock, not the user.
