Abstract
Vibration triggered game device having a housing with a vibration sensitive reference base to generate vibrations in response to a manually applied vibratory stimulus during game play, and a circuit to sense the level of those vibrations relative to a preselective, e.g. adjustable, threshold value, and including an indicator, e.g. an audible signal emitter, triggered when that level exceeds the threshold value, to indicate the achieving of an event in the game. The circuit may include a piezo transducer to detect the vibrations and to emit the signal. The housing may be a game board provided with play elements depositable on, movable along, and/or removable from, the reference base, or the housing may be an object graspable during play, with all such manual actions being effectable at a vibration level above or below the threshold value depending upon player skill and dexterity.
