Definitions
- the invention relates to a musical instrument with a Sound box made of fiber-reinforced plastic.
- musical instrument is general here all sound generating or sound reproducing Designated instruments.
- the invention is therefore based on the object To create a musical instrument of the generic type, that is easy and inexpensive to manufacture and has excellent sound qualities.
- a musical instrument in which the Hollow fibers arranged unidirectionally in the strands are. Such unidirectional alignment the hollow fibers are relatively easy to manufacture. In addition, through the unidirectional Alignment achieved particularly good sound quality will.
- the number of hollow fibers or the number, width and / or height of strands depending on the desired Damping property can be set.
- the number of hollow fibers respectively the configuration of the strands is achieved that the sound qualities of every single musical instrument influenced and optimally adjusted can be.
- the hollow fibers if necessary have a hygroscopic structure. This is very advantageous, possibly absorbing moisture and a Deterioration in the sound characteristics of the musical instrument to prevent or even through targeted Improve moisture addition.
- At least one support layer is provided, which preferably as an outer cover layer is trained.
- this support layer on the one hand a necessary strength of the resonance body reached and on the other hand this forms one editable layer, which is an individual design allowed the view of the musical instrument.
- a musical instrument provided that several, at least two unidirectional, staggered aligned layers containing hollow fibers owns. By arranging multiple layers, each containing hollow fibers can be detailed The sound is influenced by the sound box. By preferably these layers to each other will be staggered at the same time an increase in stability of the resonance body is achieved.
- Figure 1 shows a section of a resonance body 10, namely a longitudinal section through a Wall area 12.
- the resonance body 10 has a carrier layer 14 and arranged one above first layer 16, a second layer 18 and one third layer 20, each made of fiber reinforced Plastic consists of individual strands of the in fibers of hollow fibers provided in the layers consist.
- the support layer 14 forms simultaneously an outer cover layer and is preferably from a fleece containing carbon fibers or tissue.
- FIG. 2 shows the structure of that shown in FIG. 1 Wall area clarified.
- the Support layer 14 a fabric 22 made of carbon fibers, which are embedded in a plastic layer.
- the Layers 16, 18 and 20 cut open here are shown, have unidirectional orientation Strands 24, of which individual hollow fiber strands 26 are. These are hatched for clarity shown.
- Layers 16 and 18 each have alternately a strand 24 and a hollow fiber containing strand 26.
- In the layer 20 are here for example between two hollow fiber strands 26 two strands 24 are provided.
- the strands 24 respectively 26 of the individual layers 16, 18 and 20 to one another staggered.
- the hollow fiber strands 26 in at least one of the Layers 16, 18 and 20 at an angle to the in the other layers provided hollow fiber strands 26 are arranged. This angle can range from 0 to 90 °. It is also conceivable that individual of the hollow fiber strands 26 by strands Glass and / or aramid fibers can be replaced.
- transverse stabilization strands be provided, which in turn hollow, aramid, Include carbon and / or glass fibers. These strands serve the additional stabilization of the sound box. This stabilization in particular with very large resonance bodies, for example at Basses can be provided.
- the resonance body described is produced by that the individual support layers 14 and Damping layers 16, 18 and 20 are superimposed embedded in a plastic matrix, which heated to harden the plastic mass and / or can be pressurized.
- a plastic matrix By a corresponding design of the plastic matrix it is possible not just flat sound boxes manufacture, but these can be the same be so designed during curing that they for example, have curved shapes, such as this is known, among other things, from string instruments is.
- the structure of the sound box can be so be chosen that only individual parts of the sound box separately from the described support and Damping layers are made, which then in a later step in a suitable manner be composed or in a special design is conceivable that a complete sound box in one piece from the layers mentioned will be produced. This may make them special good damping properties of the sound box accessible because between individual areas, for example side panels and bottoms seamless transition of the damping layers achieved is.
- the resonance body can or part of the sound box on the Side of the support layer 14 are processed, for example by grinding so that a flat Area or, if appropriate, with appropriate thickness the support layer 14 has a curvature Surface arises.
- the support layer 14 can subsequently can be designed arbitrarily, here for details should not be received.
- microballoons in the resin of the plastic matrix can be introduced. It is also possible to just select some areas the layers with such microballoons Mistake.
- materials for the microballoons for example inorganic silicates respectively Glass chosen.
- the grain size can be between 0.01 and 0.018 mm.
- resin fillers influencing the sound properties can talc, wood flour, glass fiber chips, Cotton flakes, aluminum powder, cork, other fiber materials or the like and are dependent on the desired properties of the resonance body selected.
- the sound and damping properties of a sound box can also be influenced by this be that the resin of the plastic matrix with a Flexibilizer is provided, but here too Introduction of the flexibilizer in one or more Layers or even just in some areas can be done by one or more layers.
- the properties of the sound box can also are influenced by the fact that resins, lacquers and / or adhesives at the top and / or bottom applied to the surface of the resonance body will. Depending on the desired sound characteristics can apply a continuous layer or just individual areas of the overall relationship Underside of the sound box wetted will.
- the bottom layers of the Resonance body, the support and the support layer executed undamped. But here too Influencing the sound and damping properties Flexibilizers introduced and / or other additives, Microballoons or fibrous fillers be attached. These can vary from layer to layer Layer varies and possibly only in certain areas be introduced.
- the hollow fibers mentioned here are basic filled with air. However, it is also conceivable that Hollow fibers to influence the damping properties with special gases and / or liquids to fill.
