同槌击琴弦一样能体现出钢琴特性的,其实还有增幅装置,用更普遍的说法或称为音板(soundboard)。实际上,不通过音板就不能体现出弦的能量,在尚未领悟到这些情况之前,是不可能确切理解钢琴的真正特性的。音板结构的变化,也意味着钢琴音质的变化。由于存在这样的特征,使得我们确信,钢琴全部个性特色和机能,就体现在我们称之为“音板与弦”相结合的音响装置上。钢琴音响发生装置的机理可作如下陈述: As with the strings of a hammer, the piano features can be represented, in fact there is an amplification device, more commonly known as a soundboard. In fact, the energy of the strings can not be reflected without passing through the soundboard, and it is impossible to understand the exact nature of the piano until it has been realized. Soundboard structure changes, but also means that the piano sound quality changes. Because of the existence of such features, we are convinced that all the personality and function of the piano is reflected in what we call the “sound board and chord” combination of audio devices. The mechanism of a piano sound generator can be stated as follows:
