Definitions

  • the invention relates to musical instruments, and more particularly to a stringed musical instrument employing a soundboard, such for example a piano, and/or having a sound box e.g. a guitar, violin and the like.
  • a soundboard such for example a piano
  • a sound box e.g. a guitar, violin and the like.
  • a stringed musical instrument produces an acoustic output by excitation of the soundboard by string vibration to cause mechanical vibration in the, usually wooden, soundboard and acoustic waves in the air surrounding the soundboard .
  • O90/03025 describes an electric piano in which the soundboard of the piano can be driven. The movement of the keys may be measured and a corresponding sound excited in the sound box. The description specifically excludes the possibility that the mechanical mechanism through the strings may be used to excite the sound box in addition to the electrical excitation.
  • loudspeaker operates using bending waves.
  • a panel form loudspeaker is described in O97/09842, and can be included in electronic musical instruments, as explained in WO97/09857, which describes the use of such a loudspeaker in a digital piano.
  • the processor can add effects such as reverberation or delay.
  • the processed electronic sound must then be listened to through headphones or loudspeakers - the modified sound is not produced by the instrument itself. There is thus a need for a way of modifying the sound output directly by an instrument.
  • a musical instrument comprising at least one string that can be vibrated to produce sound; a transducer for picking up electrical signals from the instrument; a processor for processing the electrical signal; a soundboard; and an exciter on the soundboard for exciting the soundboard with the processed electrical signal to produce an acoustic output.
  • the output sound of a conventionally played instrument may be adjusted as it is played. This may produce effects such as reverberation or delay
  • the instrument may also be used to increase the volume of the instrument without the player having to play harder. This can be useful for subtle nuances such as playing natural string harmonics .
  • acoustic musical instruments e.g. hollow-bodied instruments
  • processors built in to the instrument body, thus eliminating the need for an external amplifier-speaker combination to hear the processed signal. If reverberation is added to the fed- back signal, then the instrument may produce a sound, which would belie its size. Processors are already on the market with a vast array or different effects, and these could produce very different sounds when their output is fed through the instrument soundboard. Thus the technique described above may produce new and original sounds .
  • musical instrument comprising a soundboard, at least one string, the string being capable of being vibrated mechanically by a player of the musical instrument , a mechanical coupling mechanically coupling the at least one string to the soundboard, so that vibrations of the string are coupled to the soundboard to produce an acoustic output, an input signal connector for inputting an input signal to the musical instrument, and an exciter mounted on the soundboard and coupled to the input signal connector to excite the soundboard to produce sound corresponding to a signal applied to the input signal connector, so that the soundboard can be excited simultaneously by the exciter and the vibrations of the string to produce a combined output sound signal.
  • An instrument capable of producing additional sound through the exciter permits sound such as backing tracks to be played through the instrument itself while the instrument is being played. Often, the vibrations produced by the music can be felt through the body, which helps the player feel closer to the music. This can also help feel the rhythm of a metronome beat .
  • additional voices or instrumental lines may be provided/selected or pre-programmed via a suitable interface, e.g. a MIDI.
  • a suitable interface e.g. a MIDI.
  • the performer could have a backing track reproduced while playing the main tune on the acoustic section with or without electronic enhancement of that playing.
  • the overall concept may provide limitless creative musical possibilities.
  • the musical instrument may be a string instrument having at least one string that can be plucked or bowed to produce sound.
  • String instrument is used here in the strict sense not including a piano, in which the strings are percussively struck.
  • the exciter may be positioned on the body to achieve maximum or desired modal excitation density or desired sound character or quality as taught in WO97/09842. There may be a plurality of exciters.
  • the transducer may be located on or adjacent to a string so that the original mechanical/acoustic signal from a stringed musical instrument can be directly processed and fed back to the soundboard of the instrument via the exciter so that a supplemental signal can be heard alongside the original signal .
  • this may be used as an expressive tool to permit the use of the soundboard of the instrument to reproduce the effects of the processing. The need for an instrument amplifier to hear the processed signal is accordingly avoided.
  • the mechanical vibrations of the strings of the instrument may be directly picked up and converted into an electrical signal by the transducer.
  • the exciter may be an exciter of the general kind described in WO97/09842.
  • the drive point for the exciter may be determined by experimentation and/or simulation.
  • exciter and transducer may be provided by a single transducer; any feedback may be reduced as discussed below. This may permit more accurate replay of sound.
  • the sound can be recorded by the combined transducer and exciter acting as a transducer when the instrument is being played. Later, the same vibrations can be played back through the same combined transducer/exciter to accurately reproduce the sound of the instrument being played.
  • the transducer may be a magnetic pickup. This has the advantage that it just picks up the movement of the vibrating string, not the sound on the soundboard. This can reduce effects of feedback which might otherwise arise.
  • the strings would have to be made using a ferro-magnetic material, e.g. steel.
  • a ferro-magnetic material e.g. steel.
  • the problem here would be that the three thickest strings are generally constructed from bronze windings around a nylon core, while only the three thinnest strings are constructed from steel .
  • the thicker strings would thus need to be modified to include a ferro- magnetic material.
  • the strings may often be convenient for all the strings to be made of steel to allow such magnetic pick-up. However, with some instruments all steel strings may not be applicable. With a guitar the upper strings may be steel and the lower frequency strings may be tape wound in steel rather than the usual copper etc.
  • the processor may apply continuous pitch shifting ("warbling") to the signal, as an alternative approach to reduce feedback.
  • the warbling may be at perhaps plus or minus 1% of the original frequencies.
  • an algorithm in the digital domain may be used to minimise feedback resonance.
  • Clipping may be applied to the fed back signal to limit any feedback to a predetermined level that does not intrude .
  • domestic hi-fi reproduction may also be provided by the device according to the invention.
  • a full-range exciter placed in the violin body at a pre-determined position of optimum vibration could be utilised as a pickup.
  • the output could be amplified and recorded in a conventional way.
  • the violin could be placed, preferably supported in the air at the same height it was at while played, and the signal played back through the same exciter. This would produce a sound very close to the original played piece.
  • a piano may be provided with an exciter arrangement placed inside the body.
  • a multi-track recording could be made using the exciters as mechanical - electrical transducers.
  • a piano which is to be made to a smaller scale than the original with similarly scaled and placed exciters, can be used to play back the recording.
  • This method might, when optimised, produce the played-back sound in the same way as the original, with the same colorations, timbre and acoustic wave transmission properties as the original.
  • the musical instrument according to the invention may be capable of replaying a recording of itself with superior realism and fidelity since the vibrational and acoustic radiation properties of the original (or a similar instrument) are invoked.
  • the instrument body In the primary mode where the instrument body is excited it would, of course, be less suited to the reproduction of other sounds.
  • the instrument itself is made the audio-reproducing device for the enhanced signal component, this duality further enhancing the instrument and the results that may be achieved with it.
  • the processor may comprise a microprocessor. Aspects such as control of dynamic range within chosen or safe or prescribed limits, even user adjustable and the monitoring of feedback margin and its control e.g. by gain reduction frequency shifting and/or delay techniques may be allocated to the microprocessor with appropriate software programme, sensing and control circuitry. In this way the user/musician is freed from some of the difficulties which may arise from the introduction of excess positive gain to a looped transducer reproducer chain.
  • the microprocessor may incorporate or control signal processing section to provide a range of facilities for example delay, reverberation of various kinds, 'flanging 1 , echo harmonic multiplication, sub- harmonic generation (the latter to extend the low frequency behaviour and still more useful when a low range speaker is incorporated) bass enhancement by psycho-acoustically related harmonic synthesis.
  • soft clipping may be incorporated for graceful overload characteristics, which may be deliberate aspect of sound quality control at the operating limit.
  • Features such as frequency shaping and tone colour may be added .
  • the microprocessor control may be by a wired interface or by radio or optical coupling and/or may be accomplished via a conveniently sited hard wired control panel on the body of the instrument, or a foot pedal unit.
  • an electrical output may be provided.
  • the output may include the transducer pickup signal component for later copying and or reproduction typically on conventional i.e. non- instrument -based loudspeakers.
  • the objective is not necessarily to make the instrument play louder, the effect of reverberation and additional voices will in fact have the effect of increased loudness and throw to an audience. Only moderate power may be required for a good effect, e.g. between 1 and 10 watts of rated power due to the exciter and radiation efficiency of the ensemble and the general loudness requirement.
  • a built in battery may be provided to power the instrument for some applications.
  • the present invention creates a new musical instrument, self powered or locally powered which may or may not include additional loudspeakers, resonant panel or pistonic cone type, preferably with chassis decoupling so as not to unduly restrict the free natural vibration of the instrument.
