摘要：
A keyboard musical instrument selectively generates acoustic sounds and electronic sounds depending upon a mode selected by a player, and has a hammer stopper for interrupting hammers before strikes at strings and an escape accelerator for accelerating an escape of a jack from the hammer assembly in the silent mode earlier than an escape in the acoustic sound mode, thereby preventing the hammer assembly from capture between the jack and the hammer stopper without deterioration of the piano key touch.
