PIANOS PLAYABLE IN ACOUSTIC AND SILENT MODES

摘要

A piano (100), playable in both an acoustic mode and a silent mode, includes a series of keys (110), a series of key actions (120), a series of rotatable hammers (130), and a hammer stopper (200). The hammer stopper includes at least one leash rail (210) rotatably disposed behind the hammers. The leash rail is rotatable among a first position (211) and a second position (213). The hammer stopper includes one or more leashes (220) secured to the leash rail, with each leash arranged to stop an associated hammer from striking a corresponding string (140) when the leash rail is rotated from the first position for acoustic play to the second position for silent play.
