Definitions
- the invention relates to a reed for sound production in wind instruments, wherein the reed has at least one blade tongue.
- the invention also relates to a method for producing such a reed.
- reed In some wind instruments, such as a saxophone or a clarinet, the sound is produced by means of a so-called reed, or sheet, attached to the mouthpiece of the corresponding wind instrument.
- the reed of the reed forms the oscillating part of the wind instrument and is thus actively involved in the sound production.
- Classic reeds are still made of a natural material such as pile or reed and bamboo, which ensures a good sound and a good playability of the reeds. For this reason, even today, many musicians use despite the sometimes considerable disadvantages of such reeds of natural materials, although there are now efforts, reeds of synthetic
- reeds made of natural materials change their material properties during use, which has a negative effect on the playability. affectability.
- the reed is constantly in contact with the moist exhalation air of the musician, the natural wood material of the reed absorbs the moisture and thus changes its shape, resulting in a changed playability. Only very experienced musicians can react to this changing soundscape with longer pieces.
- reeds are made of synthetic plastics available that eliminate the most common disadvantages of the reeds of classical natural materials, however, bring more disadvantages.
- reeds made of synthetic plastics usually have a vibration behavior which deviates greatly from the natural materials, which leads to a mostly unnatural sound pattern.
- edges of the blade tongue usually sharp edges that can lead to injury when playing the wind instrument due to the mouth contact.
- many musicians find it unpleasant to play on a synthetic plastic reed and touch it with the mouth.
- the object is achieved with the reed of the type mentioned in the present invention that at least the reed is made in a thermoplastic forming process of a plasticizable material containing polymeric lignin and natural fibers.
- the reed of the reed is made of a plasticizable material having polymeric lignin and natural fibers.
- Polymeric lignin is a natural polymer based on lignin, which is thermoplastically deformable in combination with natural fibers.
- the material may be in powder or pellet form and may be plasticized by exposure to thermal energy to allow it to be shaped to the desired shape.
- the polymeric lignin can be isolated by various methods from natural resources, such as pulp digestion processes. The polymeric lignin is thus present in isolated form and is then processed together with natural fibers and possibly other substances to the plasticizable material.
- the starting point is therefore a material whose matrix is made up of insulating Lignin exists, which is obtained, for example, in the production of pulp and paper from a variety of pulp digestion.
- the addition of natural fibers thus creates a semi-natural material, which is on the one hand thermoplastically deformable and on the other hand, at least partially has the properties of wood or wood-based materials.
- Tube sheets by means of thermoplastic forming processes such as injection molding, thermoforming or extruder process and energy can be produced and thus always have a consistent shape, which lead to a reproducible high quality of the product.
- such a reed of polymeric lignin and natural fibers has the further advantage that it is very easy to recycle because it consists of natural components and is therefore biodegradable. Another advantage is that such a material of polymeric lignin and natural fibers is not perceived by the musicians as unpleasant when the reed is touched with the mouth for an extended period of time. In addition, no sharp edges are formed during production on the leaf tongue, which can lead to injuries in the oral cavity.
- a material is created that has fiber components that are open at the edges, softening the material at the edges.
- tube sheet of polymeric liginin and natural fibers Another not inconsiderable advantage of a tube sheet of polymeric liginin and natural fibers is that such tube sheets are almost insensitive to air humidity, air pressure and temperature, what a long and practiced import of the reed can be omitted.
- These reeds are immediately operational and require no reworking, as is known for example from reeds of classic wood materials, such as bamboo.
- the inventors have recognized that a reed of polymeric lignin and natural fibers still has the desired vibration behavior and thus produces a sound image that is comparable to the sound images of classic reeds of wood-based materials.
- a reed of the material of the invention is particularly easy to work without damaging the reed. Thus, such a reed can be individually adapted to the needs of the musician.
- wood, spruce, beech, oak, coconut, flax, sisal, miscanthus, hemp and / or cellulose fibers come into consideration as natural fibers.
- the material further comprises a synthetic polymer. Because due to the low strength of the reeds of the reed, it is not uncommon for the leaflets to break off.
- synthetic polymers for example in an amount up to 20%, can increase the stability of the leaf tongue.
- the object is also achieved with a method for producing a reed for sound production in wind instruments according to the invention that a material comprising polymeric lignin and natural fibers, thermally plasticized and processed in the plastic state to the reed.
- the material may be a free-flowing mixture of polymeric lignin, shellac and natural fibers, which is thermally plasticized by means of a corresponding machine by supplying heat energy and then pressed for example in a mold having a negative mold of a reed. By cooling the thermally plasticized material, the material solidifies again and the tube sheet made of the polymeric lignin and the natural fibers can be removed.
- the object is also achieved with the use of a material which comprises polymeric lignin and natural fibers for producing a tube sheet for generating sound in wind instruments.
- Advantageous embodiments of the use can also be found in the corresponding subclaims.
- suitable natural fibers include vegetable fibers, the seed fibers (eg cotton, kapok, poplar fluff, bast fibers, such as hemp, jute, linen, ramie, stinging nettle, bamboo), hard fibers (eg wood, sisal, manila) or fruit fibers (eg coconut).
- vegetable fibers eg cotton, kapok, poplar fluff, bast fibers, such as hemp, jute, linen, ramie, stinging nettle, bamboo
- hard fibers eg wood, sisal, manila
- fruit fibers eg coconut
- natural animal fibers such as wool or other animal hairs (eg sheep, camel, llama, horse, cattle, goat) are also suitable for producing a correspondingly comparable vibration behavior. It is also conceivable z.
- silk or leather fibers are also suitable for producing a correspondingly comparable vibration behavior.
- Polymeric lignin may be, for example, the so-called alkali lignin, which is obtained as a by-product in pulp production.
- alkali lignin which is obtained as a by-product in pulp production.
- other polymeric lignin derivatives are also conceivable.
