Definitions
- the invention relates to a musical instrument with a resonance body made of fiber-reinforced plastic.
- musical instrument here generally means all sound-producing or sound-reproducing instruments.
- the invention is therefore based on the object of creating a musical instrument of the generic type which is simple and inexpensive to produce and has excellent sound qualities.
- a musical instrument is preferred in which the hollow fibers are arranged unidirectionally in the strands.
- Such a unidirectional alignment of the hollow fibers is relatively easy to manufacture.
- particularly good sound qualities can be achieved through the unidirectional alignment.
- the number of hollow fibers or the number, width and / or height of the strands can be determined as a function of the desired damping property.
- the hollow fibers may have a hygroscopic structure. In this way it is very advantageously possible to absorb any moisture that may occur and to prevent the sound properties of the musical instrument from deteriorating or even to improve it by specifically adding moisture.
- At least one support layer is provided, which is preferably designed as an outer cover layer.
- This supporting layer on the one hand achieves the necessary strength of the resonance body and on the other hand forms a workable layer which allows the view of the musical instrument to be individually designed.
- processing the support layer processing of the layer containing the hollow fibers, which deteriorates the sound quality, is avoided.
- a musical instrument which has a plurality of layers containing at least two mutually offset, unidirectionally oriented hollow fibers layers. The arrangement of several layers, each containing hollow fibers, can result in a detailed sound influencing of the resonance body. By arranging these layers preferably offset from one another, an increase in stability of the resonance body is achieved at the same time.
- Figure 2 is a plan view according to Figure 1 in partial section.
- the resonance body • 10 includes a carrier layer 14 and above the latter, a first layer 16, a second layer 18 and third layer 20, each made of fiber reinforced Plastic consists of individual strands of the in the layers provided fibers consist of hollow fibers.
- the support layer 14 forms an outer cover layer at the same time and preferably consists of a nonwoven or woven fabric containing carbon fibers.
- the support layer 14 has a woven fabric 22 made of carbon fibers which are embedded in a plastic layer.
- the layers 16, 18 and 20, which are shown here cut open, have unidirectionally oriented strands 24, of which individual hollow fiber strands are 26. These are hatched for clarity.
- the layers 16 and 18 alternately each have a strand 24 and a strand 26 containing hollow fibers.
- two strands 24 are provided here, for example, between two hollow fiber strands 26.
- the strands 24 or 26 of the individual layers 16, 18 and 20 are arranged offset from one another.
- FIGS. 1 and 2 The section from a resonance body shown in FIGS. 1 and 2 is shown only by way of example.
- a plurality of support layers 14 can be provided or more or less layers 16, 18 and 20 containing the hollow fiber strands 26 can be provided. It is also possible that in one or more layers 16, 18 and 20 the strands 24 and 26 are not are offset from one another, so that, for example, they are congruent or exactly offset from one another.
- the hollow fiber strands 26 in at least one of the layers 16, 18 and 20 are arranged at an angle to the hollow fiber strands 26 provided in the other layers. This angle can be chosen from 0 to 90 °. It is also conceivable for individual hollow fiber strands 26 to be replaced by strands made of glass and / or aramid fibers.
- transverse stabilization strands (not shown in FIGS. 1 and 2) can be provided, which in turn comprise hollow, aramid, carbon and / or glass fibers. These strands serve to additionally stabilize the resonance body. This stabilization will be provided in particular for very large resonance bodies, for example in the case of basses.
- the resonance body described is produced by the individual support layers 14 and damping layers 16, 18 and 20 being embedded one above the other in a plastic matrix which can be heated and / or pressurized to harden the plastic mass.
- a plastic matrix which can be heated and / or pressurized to harden the plastic mass.
- the structure of the resonance body can be selected so that only individual parts of the resonance body are produced separately from the described support and damping layers, which are then assembled in a suitable manner in a later operation or a special configuration is conceivable. that a complete resonance body is produced in one piece from the layers mentioned. In this way, particularly good damping properties of the resonance body can possibly be achieved, since a seamless transition of the damping layers is achieved between individual areas, for example side parts and bottoms.
- the resonance body or part of the resonance body can be placed on the Side of the support layer 14 are processed, for example by grinding, so that a flat surface or, if the thickness of the support layer 14 is appropriate, a surface having arches is produced.
- the support layer 14 can subsequently be designed in any manner, details not being discussed here.
- microballoons can be introduced into the resin of the plastic matrix in one or more layers. It is also possible to provide only some areas of the layers with such microballoons. Inorganic silicates or glass, for example, are selected as materials for the microballoons.
- the grain size can be between 0.01 and 0.018 mm.
- Further typical resin fillers which influence the sound properties can be talc, wood flour, glass fiber chips, cotton flakes, aluminum powder, cork, other fiber materials or the like and are selected depending on the desired properties of the resonance body.
- the sound and damping properties of a resonance body can also be influenced by the fact that the resin of the plastic matrix is provided with a flexibilizer, with the introduction of the flexibilizer in one or more layers or even only in some areas by one or more can be done in multiple layers.
- the properties of the resonance body can be influenced by the fact that resins, lacquers and / or adhesives are subsequently applied to the top and / or bottom of the surface of the resonance body. Depending on the desired sound properties, a continuous layer can be applied or only individual areas of the top or bottom of the resonance body can be wetted.
- the lowest layers of the resonance body, the support and the support layer are undamped. But here too, to influence the sound and damping properties, flexibilizers can be introduced and / or other additives, microballoons or fibrous fillers can be added. These can vary from layer to layer and may also only be introduced in some areas.
- foamable resins can also be used in the production of resonance bodies of the type described here, and that the resonance bodies can be used for any sound generating or sounding instruments, not only for pianos, grand pianos, harpsichords, spinets, harps, all string, wind and plucked instruments, but also for drums and loudspeakers.
- the hollow fibers mentioned here are basically filled with air. However, it is also conceivable to fill the hollow fibers with special gases and / or liquids to influence the damping properties.
