Definitions

  • the present invention relates to percussion instruments, preferably tuned percussion instruments comprising an acoustic pickup.
  • the present invention also relates to methods of making such percussion instruments.
  • JP-A-2009/186886 discloses an electronic percussion instrument in which strength of striking is accurately detected.
  • EP-A-3 291 223 discloses an electronic percussion instrument capable of calculating a strike position quickly.
  • US-A-2013/0192449 discloses a percussion instrument including an acoustic chamber housing having a zigzag shape.
  • Tuned percussion instruments include steelpans considered as a traditional art form in Trinidad and Tobago.
  • the steelpan has playing areas of definite pitch, on one or more continuous metal note bearing surfaces.
  • Steelpans are disclosed in US-A-2011/62510 .
  • hang also known as a handpan
  • PANArt Hangbau AG A development of the steelpan is the hang (also known as a handpan), originally conceived by PANArt Hangbau AG and since developed by a number of other makers.
  • Handpans in their basic form are a metal hollow shell of two shell segments fixed together with a tuned centre tone field of definite pitch surrounded by a number of other tone fields. A sound hole is present in the shell.
  • Handpans are disclosed in CH-A-693 319 and US design patents 794 115, 777 245, 766 356, 759 747, 737 370.
  • a percussion instrument comprising, a hollow shell, the hollow shell comprising an upper shell segment having an upper shell segment rim and a lower shell segment having a lower shell segment rim, a first outer spacer located between the upper shell segment rim and the lower shell segment rim, a second inner spacer located between the upper shell segment rim and the lower shell segment rim and spaced from the first outer spacer between the first outer spacer and the interior of the hollow shell, an acoustic pickup located between the upper shell segment rim and the lower shell segment rim and between the first outer spacer and the second inner spacer.
  • the two-spacer arrangement (with the first outer spacer and second inner spacer) is greatly advantageous.
  • the two spacers arrangement allows additional lateral pressure to be applied to secure the acoustic pickup in position and prevent it from dislodging or falling into the hollow shell during the installation process or subsequently.
  • the sound which the pickup produces once the instrument is assembled and in use is also refined, with a reduction in dead-spots and fewer areas with a volume/amplitude bias toward certain notes.
  • the second inner spacer has an improved dampening effect on the sound which is picked up; allowing the important frequencies to reach the pickup whilst the higher, less desirable frequencies may be attenuated by the spacer.
  • the hollow shell will usually comprise ferrous metal, preferably steel.
  • the metal may be treated or coated e.g. steel may be nitrided.
  • the steel may be stainless steel.
  • the first outer spacer may comprise a first outer spacer ring extending around the rim.
  • the second inner spacer may comprise a second inner spacer ring extending around the rim.
  • the second inner spacer may have a gap to allow connection to the acoustic pickup, optionally in the interior of the hollow shell.
  • the first outer spacer and/or second inner spacer advantageously comprise a nonferrous metal, preferably brass. Such metals are advantageous because they have surprisingly been found by the inventor to provide good properties and tone.
  • the first outer spacer and/or the second inner spacer may be formed as one piece (e.g. a ring, with or without a gap in the ring) or may be formed of two or more pieces.
  • first outer spacer and/or the second inner spacer are in the form of rings, then one or both of the spacers may be formed as an entire loop (with or without a gap), or in two or more sections (for example, 2, 3, 4, 5 or more sections) which is advantageous because there is less waste of material in manufacturing.
  • the first outer spacer and/or the second inner spacer are each formed of 3 sections.
  • the acoustic pickup is an elongate pickup, extending at least partially around the rim.
  • the elongate pickup may extend only partially around the rim, but usually will extend substantially wholly around the rim.
  • the acoustic pickup comprises a piezoelectric pickup, and is preferably a piezoelectric cable pickup.
  • the piezoelectric cable may extend at least partly (but preferably substantially wholly) around the rim.
  • the lower shell segment rim may comprise a lower flange preferably to support the first outer spacer, second inner spacer and the acoustic pickup.
  • the first outer spacer may be located on the distal part of the flange.
  • the second inner spacer may be located on the proximal part of the lower flange.
  • the acoustic pickup may therefore be located between the first outer spacer and second inner spacer on the lower flange.
  • the upper shell segment rim comprises an upper flange to contact the first outer spacer, second inner spacer and the acoustic pickup when assembled.
  • the first outer spacer is a first ring spacer with an outer diameter substantially the same as the outer diameter of the upper shell segment rim and flange and/or substantially the same as the outer diameter of the lower shell segment rim and flange. Furthermore, preferably, the first outer spacer is a first ring spacer with an inner diameter greater than the internal diameter of the upper shell segment rim and flange and/or greater than the internal diameter of the lower shell segment rim and flange.
  • the second inner spacer is a second ring spacer with an outer diameter less than the inner diameter of the first ring spacer, with enough difference in diameter to allow the acoustic pickup (preferably an elongate acoustic pickup) to be placed between the first outer spacer ring and second inner spacer ring.
  • the acoustic pickup preferably an elongate acoustic pickup
  • the acoustic pickup is held under pressure (i.e. vertical pressure) between the upper shell segment rim and lower shell segment rim.
  • the acoustic pickup is held under pressure (i.e. lateral pressure) between the first outer spacer and second inner spacer.
  • the depth of the spacer is preferably less than the diameter of the acoustic pickup (i.e. there is a "pinch"). This enables the acoustic pickup to be held in place with pressure applied by the upper and lower shell segment rims (and/or flanges) when in position against the, shallower, spacer.
  • the depth of the spacer (i.e. thickness of the material of the spacer) may be in the range 1.0 to 2.0 mm, preferably 1.1 mm to 1.9 mm, more preferably 1.3 mm to 1.7 mm, most preferably around 1.5 mm.

  • the difference between the depth of the spacers (i.e. thickness of the material of the spacers) and the diameter of the acoustic pickup is preferably in the range - 0.5 mm to +0.5 mm.
  • the difference between the depth of the spacer and the diameter of the acoustic pickup is in the range - 0.2 mm to +0.4 mm, more preferably -0.1 mm to +0.3 mm, most preferably 0 mm to +0.2 mm.
  • the difference between the depth of the spacers and the diameter of the acoustic pickup affects the sound and amplification of the percussion instrument. Generally, where the difference is below -0.5 mm (i.e. the diameter of the acoustic pickup is 0.5 mm or greater than the depth of the spacer), the sound is good but amplification is generally less. Where the difference is above about 0.5 mm, the amplification is good but the quality of sound may suffer.
  • the percussion instrument may further comprise an output jack installed in the hollow shell, optionally in the lower shell segment.
  • the output jack will be (electrically i.e. functionally) connected to the acoustic pickup by a connector (which may be a part of the acoustic pickup, e.g. part of a piezoelectric pickup cable).
  • the connector may pass through the gap in the second inner spacer.
  • the acoustic pickup may be fixed using adhesive, and the hollow shell may be formed by fixing the upper shell segment rim, the spacer and the lower shell segment rim with adhesive.
  • the instrument may further comprise at least one adhesive bead between the upper shell segment rim and lower shell segment rim.
  • the adhesive bead may comprise silyl modified polymer (SMP) adhesive.

  • the present invention provides a percussion instrument comprising a hollow shell having an upper shell segment and a lower shell segment, and an elongate piezoelectric acoustic pickup installed inside the hollow shell between a first outer spacer ring and a second inner spacer ring.
  • An output jack installed in the hollow shell is greatly advantageous.
  • the present invention provides a percussion instrument comprising a hollow shell having an upper shell segment and a lower shell segment, an elongate acoustic pickup installed inside the hollow shell between a first outer spacer ring and a second inner spacer ring, and an output jack (optionally a gold plated output jack) fixed in the hollow shell and connected to the acoustic pickup.
