Definitions

  • the soundboard is tensioned to increase the sensitivity of the sound intensity by at least one tensioner mounted on the soundboard.
  • the tension gives a sound dynamic that is known on all musical instruments, the adjustment of the tension gives different pitches and timbre.
  • the soundboard can be small, a few centimeters in height up to several meters.
  • a soundboard (1) is tensioned by at least one tensioner (2) constituted by a cord fixed at at least two fixing points (3 and 4). It is possible to increase the effects by adding at least one support, in this example, an easel (5) which increases the tension interactions.
  • the exciter (6) an electro-acoustic transducer, is mounted integrally with the soundboard, in this case rigid by gluing, on the back of the soundboard, at the height of the fixing point ( 3).
  • the electro-acoustic transducer emits sound notes by supplying (7) an electrical audio signal and simultaneously, it becomes a mechanical sound exciter.
  • the soundboard reacts to this mechanical vibration and then becomes a sound emitter excited by the mechanical vibration of the electro-acoustic transducer.
  • This device is a non-limiting example of the process.
  • a variant of this device is a ribbon glued to the soundboard, which delimits a volume (8) thus creating a resonant volume which adds to the result obtained an additional acoustic finesse.
  • the addition of at least one resonant volume on the soundboard generates another sound component which complements the electro-acoustic musical instrument.
  • Another variant of the device is a surface of material tensioned, for example by folding.
  • the soundboard can be perforated in order to play on the variants of different elasticity by the variation of the quantities or thicknesses of material.
