摘要：
An acoustic piano (100) is equipped with an electronic sound generating system (200), and a key bed structure (310) is angularly movable between an acoustic sound mode and an electronic sound mode for changing gaps between hammer heads (145) and sets of strings (150), thereby allowing a player to perform a music with acoustic sounds or synthesized sounds.
