Definitions

  • the present invention relates to a keyboard for an electronic musical instrument, comprising a play drawer with a plurality of stored therein piano keys and a plurality of game drawer mounted hammer heads, each driven via a mechanism of a piano key, wherein in the play drawer each hammer head an elastic, on its root fixed tongue opposite to be struck by the hammer head on actuation of the piano key, and wherein the tongue is equipped with a stop sensor.
  • Such a keyboard is from the AT 506,620 B1 Known and united the response and play of a classic grand piano or pianino hammer mechanism with the possibilities of driving an electronic musical instrument on the stop sensors.
  • the tongues are milled out of a printed circuit board.
  • the abutment sensors are strain gauges applied to the printed circuit board which measure the elastic deflection of the tongues as they are struck by the hammers and convert them into control signals for the musical instrument.
  • the aim of the present invention is to further improve such a keyboard in terms of authenticity and playability.
  • a keyboard of the aforementioned type which is characterized according to the invention in that on the side facing away from the hammer head of the tongue at a distance from the tongue, a stop for the tongue is mounted on the play slot, wherein at least in the Root of the tongue between the tongue and the stop an elastic vibration damper lies.
  • tongue, vibration damper and stop achieves, on the one hand, a reduction in the maximum deflection of the tongue even with strong keystrokes, which prevents microcracks in the tongues and leads to a long service life contributes to the keyboard, and on the other hand, the claim behavior of the tongue can be sensitively adapted to the desired stop behavior of the keyboard at the same time by the lying between the stop plate and tongue vibration damper.
  • the vibration damper As a vibration damper, a spring element, a pneumatic or hydraulic damping element or the like. be used.
  • the vibration damper is a lip made of elastic material, particularly preferably of rubber or silicone, which allows a space-saving sandwich structure of tongue, vibration damper and stop plate.
  • the tongue is approximately trapezoidal and the lip narrower than the tongue. This makes the edges of the tongue swing free, which contributes to a natural feel similar to the stop of a vibrating string.
  • the lip ends viewed from the root, from the region of the tongue intended for striking the hammer head. This allows the stop area of the tongue to swing freely, which gives the best possible feeling to the feel of a swinging string.
  • a keyboard with a plurality of keys e.g. 88 or 97 keys, as in a large concert grand piano
  • the common lip leaf may be e.g. be mounted for one or more octaves of the keyboard in one step.
  • the lip of the tongue for a piano key associated with a higher tone of the musical instrument is longer than the lip of the tongue for a piano key associated with a lower tone of the musical instrument.
  • the tongue of a piano key, which is a higher tone of the Music instrument is assigned to be shorter than the tongue for a piano key, which is associated with a lower tone of the musical instrument.
  • the hammer head of a piano key associated with a higher tone of the musical instrument may strike its tongue closer to its root than the hammer head of a piano key associated with a lower tone of the musical instrument. All of these measures make it possible to fine-tune the keyboard's response behavior in that striking a high note is perceived to be harder than striking a low note, as it does to striking strings of an acoustic grand piano or piano.
  • the circuit board is bolted or bolted in the region from which project the tongues, with the stop plate with the interposition of the vibration damper. This results in a stable sandwich construction with a long service life.
  • a further preferred embodiment of the invention is characterized in that that region of the tongue which is provided for striking the hammer head has a hole which is smaller than the stop face of the hammer head.
  • the impact sensor on the spring tongue may in itself be of any type known in the art, for example an acoustic sensor, an acceleration and vibration sensor, optical or electromagnetic sensor, a force sensor etc.
  • the stopper sensor as per itself from the AT 508.620 B1 known, at least one applied on the tongue strain gauge. Such is very thin and can be applied, for example, directly in the form of corresponding resistor pastes on the circuit board and is preferably equal to the same via the circuit board itself, ie via corresponding conductor, contacted.
  • a keyboard 1 for an electronic musical instrument such as an electronic piano, an electronic organ or a synthesizer is shown. From the keyboard 1, only a single piano key 2 is shown with its associated, described below components; it will be understood that the keyboard 1 comprises a plurality of piano keys 2 arranged side-by-side in a plan view, for example a concert grand piano structure 88 or 97 piano keys 2 in several octaves.
  • the piano keys 2 of the keyboard 1 are stored in a play tray 3 in the type two-armed lever, as well as hammer heads 4, each hammer head 4 via a - not shown here in detail - classical piano 5 is driven by the respective piano key 2, so that at Pressing or striking the piano key 2, the hammer head 4 is thrown upwards like a classic grand piano or thrown forward like a pianino.
  • the hammer head 4 is opposite - instead of a string as in a piano or piano - an elastic tongue 6, which is fixed at its root 7 in the play tray 3 and the hammer head 4 upon actuation of the piano key 2 - similar to a string - can be posted ,
  • the tongue 6 is equipped with a stop sensor 8, which detects the striking of the tongue 6, thereby preferably also measures the strength of the stop and converts it into a control signal for the electronic musical instrument.
  • the stop sensor 8 may be a switch, an electromagnetic, optical or acoustic sensor or the like. be.
  • the stop sensor 8 is formed by at least one or more on the tongue 6 applied strain gauges, which (r) is applied in particular in the region of the root 7 of the tongue 6 on this / are. In the root region 9, the strain gauge thus measures the elastic deflection of the projecting end 10 of the tongue 6 on the basis of the bending of the tongue 6 in the root region 9.
  • the tongue 6 is made of an elastic material, e.g. made of a spring metal, an elastic plastic or preferably a piece of printed circuit board (PCB) on which the abutment sensor 8, e.g. immediately applied as a strain gauge in the form of a resistor paste and contacted via the conductor of the circuit board.
  • an elastic material e.g. made of a spring metal, an elastic plastic or preferably a piece of printed circuit board (PCB) on which the abutment sensor 8, e.g. immediately applied as a strain gauge in the form of a resistor paste and contacted via the conductor of the circuit board.
  • PCB printed circuit board
  • the tongue 6 may be a separate element separately associated with that piano key 2, for example a strip of printed circuit board material.
  • the tongues 6 of a plurality of piano keys 2 juxtaposed in the keyboard 1 are made to project in a comb-like manner from a common printed circuit board 11, for example by milling or punching the printed circuit board 11, see Fig. 3a ,
  • each tongue 6 On the side facing away from the hammer head 4 each tongue 6 a stop 12 is mounted on the play tray 3 at a distance a from the tongue 6 and the projecting end 10 thereof.
  • the stop 12 prevents excessive deflection of the tongue 6 when it is struck by the hammer 4, and thus micro-cracks in the tongue 6, which could affect the life of the keyboard 1.
  • an elastic vibration damper 13 is arranged between tongue 6 and stop 12.
  • the elastic vibration damper 13 for example, a force acting between tongue 6 and stop 12 spring, a hydraulic or pneumatic damping element or the like. be.
  • the vibration damper 13 is a lip of elastic material, in particular rubber or silicone, and fills the gap of the width a between tongue 6 and stop 12 at least in the root region 9 of the tongue 6, so that there is a sandwich structure from tongue 6 - lip 13 - stop 12 results.
  • This sandwich construction or package 6 - 13 - 12 can for example be mounted on a support part 15 of the play tray 3 by means of one or more common screws 14, bolts passing through the package 6 - 13 - 12.
  • each tongue 6 in the lower or top view is preferably trapezoidal, which approximates the vibration behavior of a worn string
  • the lip 13 is preferably narrower than the tongue 6, so that the lateral edges 16 of the tongue 6 can swing freely.
  • the lip 13 ends, as in the Fig. 1 and 2 shown clearly in front of the projecting end 10 of the tongue 6, and in front of that portion 17 of the tongue on which the hammer head 4 abuts.
  • the length of the lip 13 is for example half, two-thirds or three-quarters of the length of the tongue 6.
  • the end of the lip 13 may also be rounded or trapezoidal or triangular tapered, as shown Fig. 2 seen. All of these measures contribute to the fact that the projecting end 10 and the edges 16 of the tongue 6 can swing freely when struck by the hammer 4, the stop 12 in conjunction with the lip 13 limits and dampens the maximum deflection of the tongue 6 ,
  • the stop behavior of the respective piano key 2 and thus the response or feel of the keyboard 1 can be adjusted and adapted in particular to that of a classic grand piano or pianos.
  • the stop is "harder", the shorter it is and thus the higher its tone.
  • the Fig. 3a to 3c show an advantageous structure for the keyboard 1 by combining a plurality of tongues 6 to a common circuit board 11 as discussed above ( Fig. 3a ); the combination of several lips 13 of adjacent piano keys 2, in that the lips 13 are formed in a comb-like manner projecting from a common sheet 18 of elastic material ( Fig. 3b ); and / or the combination of multiple stops 12 adjacent piano keys 2 to a common stop plate 19 (FIG. Fig. 3c ).
  • a common sandwich package of tongue-conductor lath 11, lip-leaf 18 and stop plate 19 can be made.
  • the keyboard 1 then comprises a plurality of such packages 11 - 18 - 19, or a single package 11 - 18 - 19 is used for the entire keyboard 1.
  • a hole 20 may be provided in the stop area 17 of a tongue 6, which hole is smaller than the stop area of the impacting hammer head 4.
