Definitions

  • the invention relates to an electrophonic keyboard instrument with a synthesizer, which the sound of a side instrument, especially a grand piano, on electronic Imitating the path as realistically as possible, preferably as a silent exercise instrument only with a headphone jack.
  • the invention has for its object in an electrophonic keyboard instrument to imitate the key mechanism to imitate the sound of a piano or grand piano, that the usual feel of a grand piano or piano is not lost, Instead, the behavior of the key when it is hit is as precise as possible to that of the acoustic one Originals matches.
  • the damping system is thus used to bring about the playing feeling familiar to pianists of a grand piano or piano, as such in an electrophonic practice instrument with headphones would be superfluous, taken over as authentically as possible and on adapted the requirements. Because of the space left free according to the invention or distance, the pianist feels halfway down, for example Key is the mechanical change in the weight of the key a typical, indispensable, mechanical stop feature.
  • the damper arm which normally carries and moves the damper tangent with damper tufts is invented changed so that instead weights on the damper arm (Lifting link) are arranged, the weight of damper tangent and damper tufts correspond. This technology rounds off the mechanical feel of the game of the pianist in such a way that it can be compared to that of an original grand piano.
  • the invention provides for solving the problem mentioned, that the keys of the electrophonic instrument according to the invention, each with an original Hammer, especially wing mechanics are coupled, instead of the strings there is a bar against which a hammer can be pressed by pressing Button is thrown.
  • an original mechanic too whose mechanical properties are adopted in the case of the invention, too Keyboard instruments used the actual purpose of the exercise the mechanics. So with a conventional wing mechanism when rapid repetition of tones, as required by playing trills, every time the jack may be given the opportunity to move away from the triggered state reset the hammer handle roller to the hammer for a new stop to be able to give a sufficient swing. The key return movement required for this can only be felt using original mechanics.
  • the stop and rebound bar according to the invention is attached to the instrument housing with insulating material.
  • the bar at the anchor point of the hammers is insulated. This can avoid any noise.
  • a construction according to the invention also serves this purpose, the hammer head the shape corresponding to an original hammer, in particular wing mechanism has and is covered with an impact-absorbing covering.
  • an original hammerhead felt can be used.
  • Groin insulation and / or hammer head trim can also be elastic be trained.
  • damper system on a purely electrophonic keyboard instrument is also a string superfluous.
  • conventional damper tufts have a weight of the order of magnitude of about 20 g, and this weight is loaded when the damper is raised the relevant key via the damper spoon on the keyboard. Therefore increases from a predetermined key position at which the damper spoon on the keyboard material that is necessary for further pivoting of the key Operating force.
  • the pianist feels an additional pressure point here, which he is able to provide additional information about the key position. This pressure point is therefore very important for true to the original practice and is according to the invention by a weighted lifting link simulated.
  • This lifting link is similar to one in acoustic Wings usual damper lifting member an elongated, approximately to the one in question Button parallel form and is on one of its end facing away from the keyboard Lifting link capsule articulated, which in turn is attached to a transverse bar is screwed on.
  • On the front end of the lifting link according to the invention protrudes similar to the damper spoon in the damping system of an acoustic wing Spoon that extends to above the key covered with the keyboard.
  • the spoon can also have a beak molded directly onto the lifting link be.
  • the invention provides that the lifting member in its vertical extension compared to a conventional damper lifting member is thickened and has recesses with inserted weights. Since the width of a lifting link according to the invention is determined by the key width the invention gains space in the vertical direction for the additional weights and makes it possible to change the length of the lifting link according to the invention and thus the distance of the spoon from the pivot point of an original damper lifting link take over so that the usual torque characteristic is retained.
  • the invention experiences an advantageous further development in that one of the additional Weights placed near the damper spoon or beak about there is where the articulation point of the damper tangent is at a conventional damper lifting link carrying capsule. At this point, the additional calls Weight about the same torque as that of a conventional damper system here loading damper tufts.
  • the additional load on the key movement caused by a conventional damping system To reproduce as closely as possible the original, should the additional (s) Weight (s) about the weight of the damper tufts, damper tangents and the capsule correspond.
  • the total weight of these elements is usually in the On the order of about 15 g to 20 g.
  • Such a weight can, for example be created by inserting a lead rivet.
  • the keyboard instrument according to the invention can be further optimized in that the additional weight (s) of the usually stronger damping more deeply tuned Strings are (are) larger in the middle layer than in the treble and Bass larger than the middle layer.
  • the weight of the damping system on the string increases. This measure is to be modeled by additional weights of different weights become.
  • the invention is further characterized in that above the lifting member Baffle bar is arranged to intercept the same. This will make an excessive Soaring of the lifting link with a strong keystroke avoided and the Lifting bucket immediately returns to the button.
  • Lift bar extending transversely to the longitudinal direction of the key is arranged, which has a can be lifted with the Fortepedal coupled ram and the lifting link swiveled out of the range of the key movement.
  • Wing support strip for the lifting links can be used by this is arranged pivotable about an axis parallel to its longitudinal direction. This pivot axis is preferably coaxial with the pivot axis of the lifting members placed, with two articulation points laterally outside the two outermost damper capsules are located.
  • the lifting rod is when actuated of the forte pedal compared to the preferably up to the impact bar according to the invention Swiveling lifting links are not changed and therefore neither friction nor noise generated.
  • the lifting rod can be operated like an original one Damping system can be effected by a vertically upward pusher, for this purpose in a recess of the lifting rod lined with felt intervenes.
  • the keyboard instrument consists of a provided with feet Housing for the keyboard 1, mechanics 2, damping simulator 3 and one in the Drawing, not shown, electronic assembly for the generation of electrical Signals which are sent to the pianist via headphones, also not shown be made audible.
