摘要
A silent piano is a composite keyboard musical instrument fabricated on the basis of an acoustic piano, and a pianist plays a tune by piano tones or electronic tones; when the pianist selects the electronic tones, a hammer stopper enters the trajectories of hammers, and a tandem regulating button mechanism changes damping columns onto the trajectories of jacks in such a manner that the jack is brought into contact with the damping column concurrently with a regulating button; since the damping columns are closer to the jack than the regulating buttons, the jack turns at a larger angular velocity so that the hammer is not pinched between the jack and the hammer stopper; the damping columns are moved onto a virtual plane where the regulating buttons are so that the jacks are commonly used between the silent piano and the standard acoustic piano.
