摘要：: <p>A keyboard musical instrument is a combination of an acoustic piano (100), a silent system (300) and an electronic sound generating system (200), and the silent system (300) includes a change-over mechanism (350) and a shank stopper (310) connected to the change-over mechanism so as to be changed between a free position and a blocking position, wherein the change-over mechanism gives rise to a rotation of the shank stopper around vertical axes (328/ 343) spaced apart from each other on a horizontal virtual plane so that the hammer stopper is free from a twist. </p>
