Definitions

  • the present invention relates to a pickup arrangement for an electronic percussion instrument, and more particularly, but not exclusively, to a pickup arrangement for an electronic drum.
  • Pickup arrangements for electronic drums have been previously proposed, such as pickup arrangements which comprise a relatively rigid (usually wooden) substrate which mounts a single electronic transducer element.When the substrate is struck (eg by a drumstick) the resulting shock is transmitted to the transducer element, which produces an electrical signal which varies in accordance with the force by which the substrate has been struck.
  • the resulting electrical signal is fed from the pickup arrangement to suitable electronic circuitry which includes means for processing the signal in order to produce a sound there ⁇ from (which may be a drum sound) , characteristics of the produced sound may be arranged to be effected by variation in the signal from the pickup arrangement.
  • the electronic circuitry may be arranged to produce a louder sound the harder the substrate is struck.
  • a problem with such a pickup arrangement is that the only information which can be derived from the produced signal is information on how hard the pickup arrangement has been struck (ie "dynamic" information). Although this signal could possibly be used in associated electronic circuitry to vary several characteristics of the produced sound, the variation of the signal depends only on the force with which the pickup is struck and the signal is not effected by where on the pickup is struck.
  • the sound produced by striking the drum varies not only in accordance with how hard the drum is struck but also in accordance with what part of the drum is struck.
  • Conventional acoustic drums generally comprise at least one flat playing surface which is surrounded at its periphery by a rim which projects above the playing surface the whole forming a hollow shell.
  • the drum can be struck at a number of positions. It can be struck any ⁇ where on the playing surface between the centre of the playing surface and its periphery, the sound produced by the drum varying according to where on the playing surface the drum is struck notwithstanding any variation in the force by which the drum is struck. Alternatively, the drum can be struck on its rim, in which case a different sound is produced. A further different sound may be obtained by striking both the playing surface and the rim at the same time . .
  • the present invention provides a pickup arrangement for an electronic percussion instrument compris ⁇ ing a housing provided with a plurality of " electronic transducers, the transducer being arranged to produce electrical signals when the housing is struck, from which signals information can be derived relating to with what force the housing has been struck and information relat- ing to the position of the strike on the housing.
  • the housing comprises a substrate which mounts a plurality of electronic transducers of like-type, signals produced by the electronic transducers being operable on to derive dynamic and positional information therefrom.
  • a frame for supporting the substrate, the frame having a rim which surrounds the periphery of the substrate and projects above the surface of the substrate and the frame being provided with at least one further electronic transducer.
  • a layer of insulating material is preferably interposed between the rim and the periphery of the substrate.
  • the signal given out by the frame transducer when the frame is struck can be utilised by associated electronic circuitry to effect the character ⁇ istics of a further sound produced by the electronic circuitry, the further sound being unrelated to the sound produced by striking the substrate. If both the substrate and frame are struck at the same time so that transducers on the substrate and frame give out signals at the same time, these signals may be utilised to effect the production of yet a further unrelated electronic sound. I this way similar effects can be produced as those given by a conventional acoustic drum, as discussed above.
  • the pickup arrangement is provided with a frame for support- ing the substrate there is a possibility that when the substrate is struck some of the shock of the strike may also be transmitted to the frame, effecting the frame transducer. Whilst this "cross-talk" effect may be desirable in some cases in order to effect the production of certain sound effects by associated electronic circuitry, in other cases it may not be so desirable.
  • the pickup arrangement includes a substrate supported by a frame, mounting the substrate resiliently with respect to the frame.
  • Mounting the substrate in such a manner has the effect of reducing cross-talk between transducers on the frame and transducers on the substrate, as well as giving a realistic "feel" to the pickup arrangement when it is struck.
  • Figure 1 shows a cross-sectional side view of a first embodiment of a pickup arrangement in accordance with the present invention
  • Figure 2 shows a top plan view of the pickup arrangement of Figure 1;
  • Figure 3 shows a cross-sectional side view of a further embodiment of a pickup arrangement in accordance with the present invention
  • Figure 4 shows a top plan view of the pickup arrangement of Figure 3 ? showing in outline a transducer arrangement of the pickup;
  • Figure 5 shows an exploded plan view of the transducer arrangement of the embodiment of Figures 3 and ;
  • Figure 6 shows a cross-sectional side view of a further embodiment of the present invention, illustrating a different support structure for the substrate;
  • Figure 7 shows a cross-sectional side view of yet a further embodiment of the present invention, illustrating yet another support structure for the substrate, and
  • Figure 8 shows a schematic block diagram of a typical electronic circuitry arrangement which may be used to produce electronic sounds in accordance with the signals produced by the embodiment of Figures 1 and 2.
  • the pickup arrangement depicted in Figures 1 and 2 includes a substrate in the form of a hexagonal pad 1 which has mounted on its lower surface two electronic transducers 2 and 3-
  • the transducers 2 and 3 may, for example, be piezo ⁇ electric elements fixed rigidly to the pad.
  • piezo ⁇ electric elements When piezo ⁇ electric elements are subjected to shock they deform and produce an electrical signal whose amplitude depends on the amount of deformation to which the piezo-electric element is subjected (ie the amplitude of the electrical signal provides an indication of the magnitude of the shock).
  • the transducers 2 and 3 are arranged diametric ⁇ ally opposite each other towards the periphery of the pad at equal distances from the centre of the pad 1.
  • the resulting vibration is transmitted to the transducers 2 and 3 which give out respective signals (if they are piezo- electric elements) whose amplitudes are indicative of the magnitude of the shock received by each respective transducer.
  • the transducers 2 and 3 on the pa.d 1 will give out signals of equal amplitude if the pad 1 is struck at a point which is at an equal distance from transducers 2 and 3- However, if the pad 1 is struck at a point which is closer to one transducer than the other the transducer which is closer to the point of strike will give out the signal of greatest amplitude, because it will be subjected to greater shock.
  • the signals given out by transducers 2 and 3 are therefore effected not only by how hard the pad 1 is struck, but also depend on the position of the strike on the pad 1.
  • Processing electronics associated with the pickup arrangement can therefore utilise the signals given out by transducers 2 and 3 to provide not only inform- ation on how hard the pad 1 has been struck ("dynamic" information) but also the position of the strike on the pad 1 ("positional” information). This information can then be utilised to vary the sound produced by the associated electronics, so that the sound produced depends on the position on the drum of the strike as well as on the force by which the drum is struck.
  • the associated electronic circuitry may be arranged to subtract the peak amplitude value of the signal produced by one transducer from the peak amplitude value of the signal produced by the other transducer.
  • the resultant signal would be directly related to where the pad had been struck between the two transducers 1 and 2 e if the subtraction result is zero the pad 1 has been struck at a point equidistant from both transducers. If the result is greater than zero the pad 1 has been struck nearer one transducer than the other.
  • the resultant signal could then be used to effect the sound produced by associated electronic circuitry, in sound production which depends on the position of the strike on the pad 1.
  • the positional information derived from the signals produced by the two transducers can be used to vary such characteristics of the sound produced by associated electronic circuitry as, for example, pitch, timbre, and harmonic contents. If desired the variation in sound in accordance with position of strike which is characteristic of an acoustic drum could be reproduced ie the further the pickup is struck from the centre towards one transducer the more of a sound akin to the sound produced by striking the periphery of the surface of an acoustic drum could be reproduced.
  • the signals can be added.
  • the result of the addition will indicate how hard the pad has been hit (the greater the sum the harder the pad has been hit).
  • the dynamic information can also be used to vary the characteristics of sound output by electronics associated with the drum. For example, the volume of the sound output could be increased the harder the pad is struck.
  • the pickup may be orientated in a particular manner with res ⁇ pect to the drummer when the drum kit is set up. For example, a particular drummer may have a tendency to hit a particular part of an acoustic drum when he desires a particular sound effect.
  • the pad 1 is preferably of a material which provides "controlled damping" of the vibrations occurring when the pad is struck. If the pad 1 is of very rigid material the strength of the shock reaching either transducer 2 or 3 is liable to be similar no matter where the pad 1 is struck. The signals output by the transducers 2 and 3 in this case would be virtually the same and it would therefore be very difficult to extract any positional information from them. It is therefore preferable that the pad is of a material which can provide controlled damping of vibrations, for example an air blown plastics material, such as expanded polypropylene so that any shock is damped (ie absorbed) in a controlled manner as it travels through the pad. In this case, if the pad 1 is struck over the transducer 2 the magnitude of shock reaching transducer 3 will be significantly less than the magnitude of shock reaching transducer 2.
  • the pad 1 is shown supported by a frame 5 -
  • the fram 5 has a rim ⁇ which surrounds the periphery of the pad 1 and projects above the top surface thereof but is insulated therefrom.
  • Webbing 7 depends from the rim 6 and mounts, in a position generally in line with the centre of the pad 1 , a further electronic transducer 4-
  • This electronic transducer 4 may also be a piezo-electric element.
  • the resulting vibration is transmitted to the transducer 4 via the webbing 7 due to the fact that the frame 5 is of a rigid non-brittle material such as, for example, acetyle resin (Delwyn 100), so that the magnitude of the shock transmitted to the transducer 4 does not greatly depend on what part of the frame 5 is struck.
  • the transducer will therefore produce a signal which is indicative of how hard the frame 5 is struck. If the transducer 4 is a piezo-electric element the peak value of the amplitude of the signal will be greater the harder the frame 5 is struck.
  • the signal produced by the transducer may be used to effect the production of a further sound synthesized in electronic circuitry associated with the drum.
  • electronic circuitry associated with the drum.
  • Variation in the signal produced by the transducer 4 eg variation in the amplitude of the signal
  • a characteristic of the sound such as the volume of the sound, for example.
  • the frame 5 is provided with projections 9 which are spaced at intervals around its inner surface.
  • the pad 1 is supported by these projections thus ensuring minimum contact between the frame 5 and the pad 1.
  • a layer of insulat ⁇ ing material 8, is interposed between the rim 6 and the periphery of the pad 1 , and may also cover the top surface of the pad 1.
  • the material 8 is preferably of rubber and acts as an insulator and tends to prevent any shock resulting from a blow to the rim 6 from significantly effecting the transducers 2 and 3 on the pad 1. Although a small amount of shock may be transmitted to the transducers 2 and 3 ? the magnitude of the shock will not be great. Of course, the insulator 8 will also tend to insulate the frame 5 from any shock resulting from strikes on the pad 1.
  • Any associated electronics may, for example, when all three transducers output a signal at the same time, be arranged to produce a sound similar to that produced by striking simultaneously the rim and playing surface of an acoustic drum.
  • circuitry could be arranged to detect when all the transducers produce a signal at the same time and be arranged to- produce a particular sound when this occurs.
  • the sound could "be varied in accordance with, for example, the strengths or relative strengths of the signals produced.
  • At least one F.S.R. is utilised in the transducer arrangement 30, which is arranged to produce signals from which can be derived both positional and dynamic information.
  • Figure 4 shows, in ghost outline, the position of the arrangement 30 with respect to the periphery of the pad 1.
  • the insulating layer 8 is provided over the surface of the pad 1 and transducer arrangement 30 , in a similar manner to the first embodiment.
  • the transducer arrangment 30 can best be described with reference to Figure 5 > which shows the arrangement 30 in exploded form, and also illustrates the circuit connections which would be made thereto in operation.
  • the transducer arrangement 30 comprises a "sandwhich" arrangement consisting of, from the bottom upwards, a plastic layer 31 on which is printed a conductive layer (not shown, as it is hidden under a force sensing resistive layer 32), a force sensing resistor layer 3 printed over- the conductive layer 31 • a resistive sheet layer which in the pickup arrangement is over the force sensing resistive layer 32 in contact therewith, but is shown separately in Figure 5 for the sake of convenience, and a further plastic layer 34 «
  • the resistive sheet 33 has a resistive gradient across the diameter thereof, as represented by ⁇ line 35 -
  • the signal from which dynamic information is derivable (the "dynamic signal") is taken from point 36 between resistor 37 and the conductive layer.
  • the resistor 37 is connected in operation to a voltage source V.
  • positional signal The signal from which positional information is derivable (the "positional signal") is taken from point
  • the resistance in the "circuit between earth and the point at which the pad 1 is struck will vary depending where the pad 1 as struck, as the circuit is connected to earth at point 39 at the periphery of resistive sheet layer 33, and the resistive sheet layer 33 has a resistive gradient 35 across its diameter.
  • the signal value taken from 38 therefore will therefore vary depending where on the pad 1 the pad 1 is struck, to give a positional signal. For example if the pad 1 is struck adjacent point 39 the positional signal will be zero, as point 39 is tied to earth. If the pad 1 is struck at a point adjacent 38 on the other hand, the posit onal signal will be at its maximum value, as the maximum resistance of the sheet layer 33 exists between point 38 and earth. Any strike along the line connecting points 38 and 39 will produce positional information which varies in accordance with the position of strike along the line.
  • this embodiment performs in a similar manner with respect to positional information as the embodiment of Figures 1 and 2, in that a strike at point C will produce the same positional information as a strike at point D (of strikes at points A and B in the first embodiment).
  • the production of realistic sound effects may be assured in a similar manner to the first embodiment by orientating the pickup arrangement suitably with respect to the drummer.
  • variable resist ⁇ ance according to position of strike forms part of the same circuit from which the dynamic signal is taken.
  • values of resistance are advantageously chosen such that the resistnace of the force sensitive resistor layer 3 in its working range is much greater than the resistance of the sheet 33 across its diameter.
  • Typical resistor values would be resistor 37 10K ⁇ , F.S.R.
  • Dynamic and positional information derived from this embodiment of the pickup in accordance with the present invention can be used by vary the characteristics of sound produced electronically, as for the 'first embodiment.
