Definitions

  • the present invention relates to a piano with a sound system consisting of a frame, strings tensioned in the frame and a soundboard.
  • Pianos also referred to as pianoforte or short piano, in the context of the invention include a total of those stringed instruments in which struck by means of a keyboard (keyboard) over so-called hammer clamped strings and are thus stimulated to vibrate and for the delivery of sounds.
  • Pianos are subdivided into two groups, on the one hand the so-called Pianino, in which the sound system is arranged vertically, on the other hand, the wings, in which the sound system is arranged in a horizontal orientation.
  • Part of the sound system of a piano is in addition to the frame and the strings mounted in the frame always a sound board over which the strings swing or stimulate the strings by their vibrations to their own vibrations.
  • the soundboard does not only amplify the sound of the strings, it also gives the tone the characteristic coloring, the timbre.
  • the soundboard is made in one piece and extends under all the strings from which it is excited to vibrate when it stops. This construction with a continuous, one-piece soundboard is as old as the instrument itself and was ultimately never called into question.
  • the choice of a single soundboard in the piano also implies that, unlike the low tones, where the energy of a vibrating string can be well received and amplified by the soundboard, more is regularly heard at the high notes and short strings to achieve a required sound volume as a string, often even three strings stretched parallel and must be struck by a hammer at play.
  • These strings which are also exciting to achieve the desired sound volume and to be integrated in the piano, now bring about further problems:
  • the tensile force that rests on a taut piano string is enormously high and has to be absorbed by the individual components. This applies not only to the soundboard on which the strings are playing, but also to the frame in which the strings are stretched. Additional strings and thus additional tensile loads in the context or pressure loads on the soundboard require a higher strength of the construction and thus an increased material and design effort.
  • the soundboard as a whole from at least two independent sections or elements, wherein each of the sections is assigned to a group of strings of different pitch and arranged below it.
  • the invention breaks down radically with the traditional concept of piano making, which has always been based on a single soundboard for all strings and thus the entire range of the piano. Instead, here targeted interruptions are formed or it is introduced a multi-part built-sounding board, the individual parts of the resonance of different strings from different pitches are used.
  • the individual soundboard sections can be optimally matched in terms of their choice of material, the shape and size of a comparatively narrow section of the entire tone spectrum or pitch of the piano. It is no longer necessary to find a compromise solution that satisfies the requirements of optimal resonance for tones over several octaves with a single sound board designed to be uniform for all pitches. Instead, two or even several sections can be formed and selected for a particular section of the range entire piano are optimally tuned.
  • a lighter and smaller built section of the soundboard can be provided, which absorbs and amplifies the vibrations of the shorter strings significantly better in its resonance behavior.
  • This can ultimately lead to the fact that especially in the range of these strings no longer as before for each tone instead of a string two or even more Strings must be provided, but the placement is sufficient with a single string.
  • This leads to a drastic reduction in the load to be absorbed by the supporting parts and also by the soundboard itself, which is ultimately reflected in a simplified and thus more cost-effective design of the better and accentuated tunable instrument with regard to its sound behavior over the entire range. So here are two significant benefits achieved.
  • these individual sections of the soundboard can be acoustically decoupled from one another. This can e.g. by introducing a vibration damping material at contact points or by providing a sufficiently large air gap.
  • joints or air gaps between the sections of the soundboard are adjustable and / or can be filled with appropriately adjusted selectable materials, in order to spread the vibrations from one section of the soundboard on one or to prevent several other sections or to set targeted to a desired extent.
  • the sections of the soundboard may simply be adjacent to one another, but it is also conceivable and in particular falls within the scope of the invention as an advantageous embodiment to form the soundboard by superimposing individual sections.
  • the soundboard does not only consist of a single sounding board, but of a layered structure of individual, partially superimposed resonance surfaces and can also be referred to as a resonator.
  • Such a superposition of the individual sections or segments of the soundboard is in particular carried out so that sections for the amplification of the low tones are formed over a large area and are at least partially disposed below sections for amplifying the high notes, which require a much smaller area to absorb enough of the energy of the vibrating short strings and amplify in resonance.
  • 1 denotes a soundboard for a wing, which is constructed in three parts here.
  • a total of three sections 2, 3, 4 are acoustically decoupled here
  • each group of individual strings 8, 9 and 10 are assigned to the soundboards and dock there via webs 5, 6, 7.
  • the largest and lowermost section 2 carries the long strings 8 from the bass register of the piano, which couple their vibrational energy into this section 2 of the soundboard 1 via a bridge 5. Pages 9 from the middle pitch extend over a bridge 6 over the section 3 of the total sectionally constructed soundboard 1 and couple their energy in these, compared to the provided for amplifying the bass tones Section 2 smaller and above the same arranged section 3 a.
  • the smallest section is the section 4, which is arranged acoustically decoupled above the section 3 and over which the short strings 10 for the high tones extend over the web 7 and couple their energy into this section.
  • the sections 2, 3 and 4 of the soundboard 1 are each optimally adapted in their choice of material, shape and dimensioning to the pitches of your assigned strings.
  • the wing which is equipped with the soundboard 1 schematically shown here, not only optimally in one area and compromised in other areas of its range acoustically designed, but optimized by the independent design possibility of three sections in each of 3 different areas of its range in terms his resonance and his sound volume as well as his timbre be adjusted.
  • the individual sections of the soundboard may also be arranged side by side, as well as a mixed form of sections arranged one above the other and adjacent to one another is conceivable.
  • the soundboard 1 in the embodiment shown it is possible, in particular, to simply pull the short strings 10 for the high notes, since the section 4 of the soundboard 1 is optimally adapted to the amplification and tonal arrangement of the tones from this range of the sound spectrum, and so on per se already converts the attack of a short string in a louder sound, without the need for the arrangement of two, three or even more strings about this.
  • the constructive effort otherwise required for the interception of the loads exerted by the strings can then be significantly reduced, resulting in a simpler and overall more cost-effective design or manner of the so-equipped piano.
