| The invention relates to a method for improving the sound of acoustic musical instruments by decoupling the part of a musical instrument that is directly responsible for producing the primary sound event from the elements and components that are not directly involved in producing the primary sound event. The limitation of the acoustically active part prevents elements (6, 7) that have primarily static or optical functions or serve to produce variety of playing technique from vibrating or emitting sound, since they may lead to interferences and distortions of the primary sound event. According to the invention, an intermediate layer produced from a material (1) that reduces sound conduction is arranged in the connecting zones between the elements. | ||||||

In a predetermined sound generation mode, a drive signal having a frequency characteristic corresponding to an operated key is supplied to excitation units (50L, 50H) provided on a soundboard (7). The soundboard (7) is vibrated in response to a mechanical vibration generated by the excitation units (50L, 50H) to generate an acoustic sound by the vibration of the soundboard (7). The frequency characteristics of the drive signal to be supplied to each of the excitation units (50L, 50H) is set in association with the vibration characteristics of the soundboard (7) at a position of a vibration member (51) of each excitation unit (50L, 50H) connected to the soundboard. For example, the frequency characteristics of the drive signal is set to characteristics capable of suppressing resonance of the soundboard (7).

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.

In a predetermined sound generation mode, a drive signal having a frequency characteristic corresponding to an operated key is supplied to an excitation unit 50 provided on a soundboard (7). In response to a mechanical vibration generated by the excitation unit (50), the soundboard (7) is vibrated so as to generate an acoustic vibration sound corresponding to the operated key. The excitation unit (50) is supported by a supporting unit (55) such that less or no load of the excitation unit except a vibration member (51) vibrated in response to the drive signal is applied to the soundboard (7). Thus, only a load of the vibration member (51) which is a very light portion of the excitation unit (50) is applied to the soundboard (7), thereby vibration characteristics of the soundboard (7) being hardly affected. There is provided a sounding body (5) to be struck by a hammer (4) in response to the operation of the key. When a sound damping mode is selected, a stopper (40) is permitted to prevent the hammer from striking the sounding body (5). Consequently, sound generation based on the sounding body and sound generation based on the vibration of the soundboard can be combined selectively.

Furthermore, each key hammer strikes four dedicated strings as opposed to the three shared strings found on conventional pianos. The string construction eliminates the need for string sets to be shared with adjacent keys so that tuning or breakage of a string only affects a single key as opposed to adjacent keys. | ||||||
