摘要： Keyboard apparatus includes: a key (20) supported for pivoting movement about a pivot point (12); a mass member (30) for imparting a reaction force to performance operation of the key in interlocked relation to the key; a transmission member (46) provided in abutment with both of the key and mass member to transmit a load from one of the key and mass member to the other; and an electromagnetic actuator (40) for driving, via a fixed coil (41), the transmission member toward at least one of the key and mass member. Good key touch feeling can be achieved not only by a load applied from the mass member to the key but also through load control by the actuator. Thus, it is possible to faithfully reproduce a key touch feeling approximate to that in a natural keyboard instrument, such as an acoustic piano, with a simple construction and facilitated control.

摘要： In response to an operation of a key, a drive signal indicating a sound waveform corresponding to the key is supplied to an excitation unit (50) provided on a soundboard (7). The soundboard (7) is vibrated in response to a mechanical vibration generated by the excitation unit (50) and generates an actively-vibrated-soundboard sound as well as an acoustic effect generated by propagation of the vibration of the soundboard (7) to a string (5). The excitation unit (50) has a voice coil (512) excited by the drive signal. The length of the voice coil (512) is equal to or smaller than a sum of a magnetic path width (mw) of a magnetic path space (525) and a double of a maximum deflection amount (sw) of the vibration member (51) connected to the soundboard (7). By determining the length of the voice coil (512) as described above, an effective drive force for exciting the soundboard (7) can be obtained and an enhanced responsiveness in a high frequency band can be obtained.
摘要翻译：响应于琴键的操作，指示与琴键对应的声音波形的驱动信号被提供给设置在共鸣板（7）上的激励单元（50）。音板（7）响应于由激励单元（50）产生的机械振动而振动，并且产生有源振动的音板声音以及由音板（7）的振动传播到音响板字符串（5）。激励单元（50）具有由驱动信号激励的音圈（512）。音圈（512）的长度等于或小于磁路空间（525）的磁路宽度（mw）和振动部件（51）的最大偏转量（sw）的两倍之和）连接到音板（7）。通过如上所述确定音圈（512）的长度，可以获得用于激励共鸣板（7）的有效驱动力，并且可以获得高频带中的增强的响应性。
