Abstract
A celesta produces sounds in response to keying-in by striking sound bars with hammer units associated therewith, and key action mechanisms are provided between the keys and the hammer units, wherein the hammer units are located under the associated sound bars so that the hammers promptly return to initial positions by the aid of the gravity exerted thereon.
Claims12
A celesta comprising
- a) a plurality of keys, each of said plurality of keys being swingable when selectively depressed by a player;
- b) a plurality of sound bars respectively associated with said plurality of keys;
- c) a plurality of hammer units respectively associated with said plurality of sound bars for striking said associated sound bars, and located under said associated sound bars;
- d) a plurality of key action mechanisms respectively coupled between said plurality of keys and said plurality of hammer units, and causing said associated hammer units to strike said associated sound bars when said associated keys swing, said plurality of key action mechanisms allowing said associated hammer units to return to respective initial positions by the aid of at least the gravity exerted thereon after said associated hammer units strike said associated sound bars;
- and
- e) a plurality of resonance boxes provided in association with said plurality of sound bars, respectively, an adjusting mechanism being provided between each of said plurality of resonance boxes and each of said plurality of sound bars for adjusting a gap therebetween.
