FR2884958A1 - Slide didjeridoo for Australian aborigine, has right pierced small and large tubes sliding with respect to each other, where didjeridoo is made of semi-heavy wood or heavy wood with specific density, and mouthpiece made of wood or resin - Google Patents

Abstract

The didjeridoo has a right pierced small tube (2) and a large tube (1) arranged for sliding with respect to each other, where the didjeridoo is made of either a semi-heavy wood with a density of 0.65 to 0.85 grams per centimeter cube or a heavy wood with a density of 0.85 to 0.90 grams per centimeter cube. A pair of joints (5, 6) is fixed on the inner and outer perimeters of the large tube and the small tube, respectively. An interchangeable mouthpiece is made of wood or resin and is cased at an end of the small tube.

Description

The present invention relates to a wooden slide didgeridoo.

  The didgeridoo is a musical instrument traditionally played by Australian Aborigines. It comes in the form of a natural horn, made of eucalyptus wood, hollowed out by termites. The didgeridoo is equipped with a mouthpiece made of beeswax. It is a mono-tonal instrument. The nature of his tone and the pitch of his tone are random.

  On the other hand, it is possible to find telescopic didgeridoos made of synthetic materials. They have the advantage of being easy to achieve but their acoustic and musical qualities are limited.

  The object of the invention is therefore to obtain a didgeridoo for playing in various tones, in an acoustic and musical optimized quality.

  This objective is achieved by a wooden sliding didgeridoo, made from semi-heavy type (density of 0. 65 to 85 g / cm3) and heavy wood species (density 85 to 90). g./cm3) having all the mechanical and acoustic qualities sought. The use of wood in the realization of the instrument gives it an optimized quality stamp.

  The wooden slide didgeridoo is characterized by an expanded polytetrafluoroethylene (PTFE) seam system or textile material joints to seal the slide.

  The wooden slide didgeridoo is characterized by the application, inside the wood tubes, of a two-component high-solids polyurethane type HS (Hight Solide) varnish. This optimizes the acoustics of the instrument.

  The wooden slide didgeridoo is characterized by a perfectly straight bore, which gives it a good acoustic impedance due to the nature of the resistance of the air column, for a precise and dynamic playing quality, and for an acoustic development optimized.

  The wooden slide didgeridoo is characterized by a horn at the instrument's exit, for an optimization of the acoustics.

  The wooden didgeridoo is characterized by a mouthpiece that can be made of wood or resin. It replaces beeswax, traditionally used, which is unstable and unhygienic. Similarly, the mouth may be interchangeable.

  It will be attached to the end of the tube (2). Several models are available depending on the player's preferences.

  The wooden slide didgeridoo in this form is susceptible of industrial applications. Indeed, following the characteristics of the present invention, the manufacturer will be able to give a consistency in the quality of his product. Which is not the case with the traditional didgeridoos and more largely with the imitations of traditional Australian didgeridoos dug by the man or the didgeridoos in synthetic materials.

  The present invention will be better understood with reference to the description of a schematic form and with reference to the appended drawing in which: FIG. 1 represents a longitudinal section of the didgeridoo according to the invention.

  Referring to Figure 1, the wooden slide didgeridoo shown is composed of two tubes of straight percussions, made of wood and slidable one into the other.

  The sealing of the slide is ensured by a system of joints.
