电子键盘乐器
摘要：
一种电子键盘乐器，其可以实现具有与声学钢琴相同的良好音质的自然音。振动由平板件制成的音板(33)从而产生乐音。第一演奏信号产生器(22)基于键盘(17)的多个键的操作状态产生第一演奏信号。第二演奏信号产生器(23)基于多个键的操作和踏板(18)的操作产生与第一演奏信号不同的第二演奏信号。扬声器(41A～41D)基于由第一演奏信号产生器(22)产生的第一演奏信号产生乐音。安装在音板(33)上的变换器(21A～21C)基于由第二演奏信号产生器(23)产生的第二演奏信号振动音板(33)。
摘要（英）：

An electronic keyboard musical instrument which can realize natural sounds with favorable sound quality as an acoustic piano. A sound board (33) made of a plate member is vibrated so as to generate musical tones. A first performance signal generator (22) generates a first performance signal based on the operating state of a plurality of keys of a keyboard (17). A second performance signal generator (23) generates a second performance signal, which is different from the first performance signal, based on the operation of the plurality of keys and the operation of a pedal (18). Speakers (41A to41D) generates musical tones based on the first performance signal generated by the first performance signal generator (22). Transducers (21A to 21C) mounted to the sound board (33) vibrate the soundboard (33) based on the second performance signal generated by the second performance signal generator (23).
