[0038] see attached figure 2 , embodying the compound keyboard instrument of the present invention mainly includes an acoustic piano 5 and a mute system 6 . In this embodiment, the acoustic piano 5 is a grand (grand) piano, and the mute system 6 allows the pianist to selectively play a piece of music in acoustic or electronic tones. When the player selects the acoustic tone, the composite keyboard instrument is in the acoustic sound mode; on the other hand, in the silent mode, the player practices fingering without the acoustic tone. Thus, the composite keyboard instrument can be switched between the acoustic sound mode and the silent mode.

[0039] The acoustic piano 5 includes a plurality of keys 7 , a plurality of action mechanisms 8 , and an assembly of a plurality of strings 9 and hammers 13 . The black keys 7 and white keys 7 are arranged in a known pattern and can rotate around a balance rail (not shown). The temperament of the scale is assigned to each black key / wh...

Abstract

A compound keyboard instrument provided with a silencing system (6) by which one section of music can be played by a player with electronic tone rather than acoustics tone. The silencing system (6) includes a percussion hammer stop (30) for resiling the percussion hammer after keyboard action mechanism (8) escapement and before knocking the strings, a timing changing mechanism (260) for speeding up the percussion hammer escapement, and a driving mechanism (160 / 170) for transmitting the torque of the drive motor (150) to the percussion hammer stop (30) and timing changing mechanism (260). The invention simplifies internal structure thereof.

Description

technical field [0001] The present invention relates to a keyboard musical instrument, and more particularly, the present invention relates to a composite keyboard musical instrument for selectively playing a piece of music with acoustic tones and electronic tones, and a mute system used in such a musical instrument Background technique [0002] The composite keyboard musical instrument is provided with a hammer stopper. The player gives instructions to the instrument to shift the hammer stop to a free position or a blocking position before he / she plays. Assuming that the player wants to play a piece of music with the acoustic tone, he just instructs the composite keyboard instrument to change the hammer stopper to the free position. Composite keyboard instruments keep the hammer stops out of the trajectory of the hammer so that the hammer stops do not impede the movement of the hammers. While the player's fingers are playing on the keyboard, the pressed...
