Description

[0001] musical string

[0002] The invention relates to a musical string according to the preamble of claim 1.

[0003] There are various or different musical genres, such as classical music, jazz and pop music.

[0004] Musical strings possess certain properties that determine their sound and how they can be played or stimulated by the musician on the instrument. These characteristics—according to the standard technical terms—in particular include response, damping, timbre, whistling, modulation capability, and tonal shapes.

[0005] It has been shown that musical strings perfectly suited for playing classical music, and capable of beautifully reproducing pieces of this genre, can exhibit significant disadvantages in other musical styles, particularly regarding individual tone production and reproduction. In jazz, in particular, classical strings can limit the musician's interpretive and expressive possibilities. The musician cannot fully develop their expression and is restricted in their performance. The musician's interpretation of a piece is hindered, and the artist is thus unable to realize their full potential. Besides jazz, this disadvantage also affects various nationally transmitted and folk-practiced musical styles. Examples of such styles include the so-called "folk music" of East Asia and the Middle East.

[0006] US Patent 2,049,769 A describes musical strings with a core and at least one winding layer. The string core can be formed from several intertwined wires, as shown in Figures 4 and 18. The winding layer, in turn, can consist of several individual elements.

[0007] US 2023 / 260483 A1 describes a musical string in which a winding layer has multiple winding elements made of different materials. It does not describe a string core made of different materials. US 2006 / 196339 A1 and US 6348646 B1 each describe a thermal treatment of a musical string.

[0008] The object of the invention is therefore to provide a musical string of the type mentioned above, with which the aforementioned disadvantages can be avoided, and which is designed for the reproduction of a specific genre of music.

[0009] According to the invention, this is achieved by the features of claim 1.

[0010] This allows for the creation of a musical string specifically designed and trained for the reproduction of a particular, preferably only one, genre of music. This enables the creation of a musical string that is tailored to the wishes and requirements of musicians, especially individual musicians. This allows artists to fully develop their skills and share their genius with others. Such musical strings can be designed and manufactured to possess playing characteristics that have proven advantageous in the reproduction of specific musical genres or pieces.

[0011] This allows a musical string to be produced with a predefinable, non-constant torsional vibration. Properties of the musical string, in particular response, damping, timbre, whistling characteristics, modulation capability, and / or sound shapes, can thus be predefinably influenced and specifically adjusted.

[0012] The invention further relates to a method for manufacturing a musical string according to claim 16.

[0013] The invention therefore further aims to provide a method for manufacturing a musical string of the aforementioned type, with which the aforementioned disadvantages can be avoided, with which

[0014] According to the invention, this is achieved by the features of claim 16. This allows the Young's modulus and / or the tensile strength and / or the springback ratio of a wire to be specifically and predictably influenced. In particular, this makes it possible to ensure that two wires made of identical materials each have predictably different springback ratios. This makes it easy to ensure that the first length segment extends to individual areas of the musical string.

[0015] The dependent claims relate to further advantageous embodiments of the invention.

[0016] The invention is described in more detail with reference to the enclosed drawings, in which only preferred embodiments are shown by way of example. These show:

[0017] Fig. 1 shows a preferred embodiment of a musical string according to the invention in a partially cutaway view;

[0018] Fig. 2 shows a first embodiment of a string core of a musical string according to the invention in a cutaway view;

[0019] Fig. 3 shows a second embodiment of a string core of a musical string according to the invention in a cutaway view; and

[0020] Fig. 4 a violin.

[0021] Fig. 1 shows a section of a musical string 1 for a stringed instrument 27 with a predetermined scale length 28, in particular a guitar and / or a bowed instrument, preferably a bowed instrument of the violin family, with a supporting string core 2, which is designed as a wire rope 3, wherein the wire rope 3 has a core 4 and a sheath 5, wherein the core 4 comprises at least three core wires 6, 7, 8, and wherein the sheath 5 comprises at least six sheath wires 9, 10, 11, 12, 13, 14, 15, 16, 17 arranged side by side, wherein at least one first sheath wire 9 has a first modulus of elasticity, a first tensile strength, and a first springback ratio, wherein at least one second sheath wire 10 has a second modulus of elasticity, a second tensile strength, and a second springback ratio, wherein at least in a predetermined first length section 37 of the musical string 1 - the second modulus of elasticity can be predefinably different from the first modulus of elasticity, and / or

[0022] - the second tensile strength is predictably different from the first tensile strength, and / or

[0023] - the second springback ratio can be predetermined to be different from the first springback ratio.

[0024] This allows for the creation of a musical string 1 specifically designed and trained for the reproduction of a particular musical genre, preferably only one, especially jazz. This allows for the creation of a musical string 1 that is trained in such a way as to meet the wishes and requirements of musicians, especially individual musicians. This enables artists to fully develop their skills and share their genius with others. Such musical strings 1 can be trained and manufactured to possess playing characteristics that have proven advantageous in the reproduction of specific musical genres or pieces.

[0025] This allows a musical string 1 to be generated with a predefinable, non-constant torsional vibration. Properties of the musical string 1, in particular response, damping, timbre, whistling characteristics, modulation capability and / or the sound shapes, can thus be predefinably influenced and specifically adjusted.

[0026] The embodiments and detailed views shown in Figures 1, 2, and 3 are simplified representations. The proportions do not necessarily correspond to the intended actual proportions. For better understanding, individual parts may be shown in a greatly enlarged view or with significantly exaggerated proportions.

[0027] The musical strings 1 according to the invention are designed to generate tone-producing vibrations. A specific musical string 1 is intended for use on a particular type of musical instrument. The corresponding instrument for which a musical string 1 is intended or designed is also indicated on the musical string 1 itself or on its packaging. These musical strings 1 are intended for stringed instruments 27. In particular, these musical strings 1 are intended for guitars or bowed string instruments. A preferred application for such musical strings 1 is bowed string instruments such as the instruments of the violin family, hence the violin 30, the viola, the cello, and the bass, double bass, or bass fiddle. Other preferred instruments for use with musical strings 1 according to the invention are the viola da gamba and the viola d'amore.Furthermore, these can also be advantageously used for guitars, in particular the different types of guitars. Such musical strings 1 according to the invention can preferably be provided for all bowed and / or plucked stringed instruments 27 in which the vibrating length of the musical string 1 is varied to produce sounds with different fundamental vibrations. In such stringed instruments 27, the musical strings 1 are pressed onto the fretboard of the stringed instrument 27 by the player's fingers during playing, thus varying the vibrating length and consequently also the pitch. Preferred further stringed instruments 27 are: banjos, sitar, lutes, oud, p'i-pa, gekkin, balalaika, vina, and tampura.

[0028] The musical strings in question are preferably not intended and / or designed for instruments which have separate strings for each note, fixed in a housing, and where the strings are not plucked by the musician to produce different pitches. These include, in particular, pianos, harpsichords, zithers, harps, and similar instruments.

[0029] A stringed instrument 27, in particular the stringed instruments 27 of the guitar family and the violin family, has a so-called scale length 28. The term "scale length" refers, in the case of stringed instruments of the violin family 30, to the distance between the bridge 34 and the nut 35 of the instrument. In the case of guitars, this is the distance between the nut and the bridge. Fig. 4 shows a schematic plan view of a violin. The relevant parts are each labeled with reference symbols. Every stringed instrument of the opposite family has both a bridge 34 and a nut 35. The individual stringed instruments of the violin family 30 each have the following scale length 28: Stringed instrument: Scale length:

[0030] 4 / 4 violin 32.5 cm

[0031] 3 / 4 violin 30.5 cm

[0032] 1 / 2 violin 28.3 cm

[0033] 1 / 4 violin 25.5 - 26 cm

[0034] 1 / 8 violin 23 - 24 cm

[0035] 1 / 16 violin 21.5 cm

[0036] 4 / 4 viola 37 - 37.5 cm

[0044] 1 / 2-bass 96.5 cm

[0045] 1 / 4 bass 90 - 90.5 cm

[0046] The individual measurements 28 exhibit a length tolerance of less than 5% in practice, preferably less than 3%, and in particular approximately 1.5%. The measurement

[0047] As already mentioned, musical strings 1 are designed to produce sound-generating vibrations. Each musical string 1 has a tuning pitch and a so-called tuning weight as its defining characteristics. The tuning pitch indicates the fundamental tone at which the scale length 28 vibrates when the musical string 1 is tensioned with the tuning weight and set into vibration. In this technical context, the term "tuning weight" refers to the force with which the musical string 1 must be tensioned. Another term for the tuning weight is string tension.

[0048] The musical strings 1 according to the invention have a string core 2 which is designed and configured to withstand the force or tension to which the musical string is subjected.

[0049] 1. The string core 2 is therefore load-bearing.

[0050] The musical string 1 further preferably has at least one first winding element, which first winding element in the form of a helical line around the string core

[0051] 2 is wound. The first winding element is part of a first winding layer 19, which may also include further winding elements. The preferred embodiment according to Fig. 1 has, in addition to the first winding layer 19, a second winding layer 20 comprising the first winding layer 19. A preferred third winding layer 21 is further arranged around the second winding layer 20. The winding elements of the different winding layers 19, 20, 21 have different cross-sections.

[0052] The string core 2 is designed as a wire rope 3. A string core 2 made of a wire rope 3 is known, for example, from EP 2 131 352 A1 of the applicant.

[0053] The wire rope 3 has a core 4 and a sheath 5, with the sheath 5 surrounding or enclosing the core 4.

[0054] The core 4 forms the inner core area of ​​the wire rope 3. The core 4 comprises at least three core wires 6, 7, 8: the first core wire 6, the second core wire 7 and the third core wire 8. The at least three core wires 6, 7, 8 are wound helically around a geometric center of the string core 2.

[0055] It may preferably be provided that the wire rope is located essentially in the center.

[0056] 3. A core insert 18 comprising a predetermined number of polymer threads is arranged, wherein it is preferably provided that the polymer threads comprise polyamides, aramid fibers, PEK, PEEK, PBT, polyester, nylon, polyethylene, PET, PEET, PES, PE, PP, POM, PTFE, PVDF, PVDC and / or PVC. It is particularly preferred that the polymer threads are formed from polyamide 6.4, 6.6, 6.10 or 6.12 with a fineness of 32 dtex to 200 dtex or from polyester PES with a fineness between 60 dtex and 500 dtex, wherein combinations of different polymer threads may also be provided.

[0057] The sheath 5 comprises at least six sheath wires 9, 10, 11, 12, 13, 14, 15, 16, 17, which are wound helically around the core 4. The at least six sheath wires 9, 10, 11, 12, 13, 14, 15, 16, 17 comprise the first sheath wire 9, the second sheath wire 10, the third sheath wire 11, the fourth sheath wire 12, the fifth sheath wire 13, and the sixth sheath wire 14. The second embodiment of a string core 2 shown in Fig. 3 further comprises a seventh sheath wire 15, an eighth sheath wire 16, and a ninth sheath wire 17.

[0058] Figures 2 and 3 each show an envelope 23 of the mantle 5.

[0059] Each of the sheath wires 9, 10, 11, 12, 13, 14, 15, 16, 17 has a modulus of elasticity, hence a so-called modulus of elasticity.

[0060] Each of the sheath wires 9, 10, 11, 12, 13, 14, 15, 16, 17 has a tensile strength. The tensile strength is the stress resulting from the maximum force applied to the initial cross-sectional area.

[0061] Each of the sheathed wires 9, 10, 11, 12, 13, 14, 15, 16, 17 has a springback ratio. According to Dubbel's Handbook of Mechanical Engineering, the springback ratio is the ratio of the unloaded bending angle after a bending operation to the maximum bending angle achieved under the bending force during the bending operation. The springback ratio also depends on the bending radius, so the same bending radius must always be used for comparative measurements.

[0062] The first sheath wire 9 has a first modulus of elasticity, a first tensile strength, and a first springback ratio. The second sheath wire 10 has a second modulus of elasticity, a second tensile strength, and a second springback ratio.

[0063] Preferably, the first sheath wire 9 is part of a first sheath wire group, which, in addition to the first sheath wire 9, comprises at least one further sheath wire 11, 12, 13, 14, 15, 16, 17 of the remaining at least four sheath wires 11, 12, 13, 14, 15, 16, 17. In particular, each of the sheath wires 9, 11, 12, 13, 14, 15, 16, 17 of the first sheath wire group has the first modulus of elasticity, the first tensile strength, and the first springback ratio.

[0064] Preferably, the second sheath wire 10 is part of a second sheath wire group, which, in addition to the second sheath wire 10, comprises at least one further sheath wire 11, 12, 13, 14, 15, 16, 17 of the remaining at least four sheath wires 11, 12, 13, 14, 15, 16, 17. In particular, each of the sheath wires 10, 11, 12, 13, 14, 15, 16, 17 of the second sheath wire group has the second modulus of elasticity, the second tensile strength, and the second springback ratio.

[0065] The sheath 5 can furthermore also have a third sheath-wire group with at least one sheath wire 11 , 12, 13, 14, 15, 16, 17, which third sheath-wire group has a third modulus of elasticity, a third tensile strength and a third springback ratio.

[0066] Each sheath wire 9, 10, 11, 12, 13, 14, 15, 16, 17 is only part of a single sheath wire group.

[0067] According to the invention, the first sheath wire 9 differs from the second sheath wire 10 with regard to the modulus of elasticity and / or the tensile strength and / or the springback ratio.

[0068] Provided that the sheath 5 also has at least one sheath wire 11, 12, 13, 14, 15, 16, 17 with a third modulus of elasticity, a third tensile strength and a third springback ratio, the third modulus of elasticity and / or the third tensile strength and / or the third springback ratio differs from the corresponding properties of both the first sheath wire 9 and the second sheath wire 10.

[0069] Preferably, the second modulus of elasticity differs from the first modulus of elasticity by at least 2%, in particular by 5%, and most preferably by at least 10%. This is achieved by making the second modulus of elasticity arbitrarily larger or smaller than the first modulus of elasticity. The percentages refer to the first modulus of elasticity as a reference value.

[0070] In particular, it is provided that the second tensile strength differs from the first tensile strength by at least 2%, in particular by 5%, and most preferably by at least 10%. This means that the second tensile strength is predefinably greater or less than the first tensile strength. The percentages refer to the first tensile strength as a reference value.

[0071] Preferably, the second springback ratio differs from the first springback ratio by at least 2%, in particular by 5%, and most preferably by at least 10%. This means that the second springback ratio can be predefinably larger or smaller than the first springback ratio. The percentages refer to the first springback ratio as a reference value.

[0072] According to the invention, the modulus of elasticity and / or the tensile strength and / or the springback ratio of the first sheath wire 9 and the second sheath wire differ from each other at least in a first length section 37 of the music string 1.

[0073] The first length section 37 can essentially extend over the entire length of the music string 1. This is particularly easy to implement from a manufacturing perspective.

[0074] According to a first alternative embodiment, the first length section 37 is defined at least, and in particular substantially exactly, by the scale length 28. This allows the differences in the relevant properties to be limited to the area of ​​the musical string 1 that is altered by the hands of the respective musician. In the other areas, in the case of the violin the area between the bridge 34 and the side rest 36, the relevant properties continue to exhibit substantially identical values. This allows for targeted influence on the damping in specific frequency ranges.

[0075] According to a second alternative embodiment, the first length section 37 is arranged within the scale length 28 and is between 8% and 80% of the scale length 28, in particular between 15% and 65% of the scale length 28. This allows for the targeted creation of individual areas with specific, different properties, and enables a much more differentiated and targeted individual design of the musical string 1.

[0076] According to a third alternative embodiment, the musical string 1 further comprises at least a second length section, preferably a third length section, and in particular a definable plurality of length sections, each of which is between 5% and 15% of the scale length. It is provided that between the first length section 37 and the second length section with substantially the same differences in modulus of elasticity and / or tensile strength and / or springback ratio, a length section is arranged in which no such differences exist. The areas in which, according to the invention, different moduli of elasticity and / or different tensile strengths and / or different springback ratios of the first sheath wire 9 and the second sheath wire predominate, and those areas in which this is not the case, would alternate.

[0077] Preferably, the first sheath wire 9, and in particular all sheath wires 9, 11, 12, 13, 14, 15, 16, 17 of the first sheath wire group, comprise or consist of a steel. In particular, the steel comprises at least one alloying element selected from the group consisting of: carbon, chromium, nickel, molybdenum, vanadium, manganese, and tungsten. Steels with these materials and their different properties are known. Particularly preferably, the first sheath wire 9, and especially all sheath wires 9, 11, 12, 13, 14, 15, 16, 17 of the first sheath wire group, comprise a so-called carbon steel, preferably with a carbon content between 0.01% and 0.03%, or a so-called chromium-nickel steel, preferably with a chromium content between 17% and 20% and a nickel content between 8% and 10%. These two types of steel have proven to be particularly advantageous in a load-bearing core of a musical string.

[0078] The modulus of elasticity of the preferred steel types is between 180 GPa and 210 GPa.

[0079] Various types of steel with different tensile strengths are known. Experience shows that the tensile strengths of two different types of steel can differ considerably.

[0080] The second sheath wire 10, in particular all sheath wires 10, 11, 12, 13, 14, 15, 16, 17 of the second sheath wire group, are preferably made of a metal, in particular a pure metal, selected from the group consisting of: aluminum, magnesium, iron, chromium, nickel, silicon, silver, gold, platinum, rhodium, ruthenium, rhenium, palladium, osmium, copper, tungsten, tantalum, manganese, molybdenum. These metals have different properties, both with regard to their modulus of elasticity and their tensile strength, and have proven advantageous for selectively influencing and precisely adjusting the sound characteristics and playability of a musical string 1.

[0081] Preferably, the second sheath wire 10, in particular all sheath wires 10, 11, 12, 13, 14, 15, 16, 17 of the second sheath wire group, is formed from an alloy comprising a metal, in particular a base metal, selected from the group: aluminum, magnesium, iron, chromium, nickel, silicon, silver, gold, platinum, rhodium, ruthenium, rhenium, palladium, osmium, copper, tungsten, tantalum, manganese, molybdenum. The second sheath wire 10 is particularly preferred and is made from an alloy selected from the group of: aluminum-magnesium alloys, aluminum-magnesium-manganese alloys, silver-copper alloys, silver-platinum alloys, silver-rhodium alloys, silver-palladium alloys, iron-chromium-nickel-silicon-aluminium alloys, beryllium alloy, phosphor bronze, iron-aluminium-chromium alloys, iron-chromium-aluminium alloys, aluminum-iron-chromium alloys, aluminum-silicon-chromium alloys.Alloys exhibit very different moduli of elasticity (E-modulus) as well as tensile strengths. The E-modulus, in particular, ranges from 50 to 700 GPa. These alloys also exhibit other differences that may be desirable when used in the core of a musical string. Alloys with the specified base metals, and especially those listed, have already proven advantageous in the production of musical strings.

[0082] According to a preferred embodiment of the present invention, the first sheath wire 9, and in particular all sheath wires 9, 11, 12, 13, 14, 15, 16, 17 of the first sheath wire group, and / or the second sheath wire 10, and in particular all sheath wires 10, 11, 12, 13, 14, 15, 16, 17 of the second sheath wire group, has a surface coating, in particular comprising a metal, preferably selected from the group consisting of brass, tin, nickel, and / or a plastic, preferably a polymer. Such coatings have proven effective with regard to the long-term durability of the string core. Furthermore, they allow for a slight influence on and fine-tuning of the tonal character.

[0083] In a method for manufacturing a musical string 1, it is provided that three core wires 6, 7, 8 are twisted together to form a core 4 of a wire rope 3.

[0084] Subsequently, a sheath 5 is formed around the core 4. For this purpose, the first sheath wire 9 is unwound from a first roll and then subjected to a predetermined length of predetermined heat treatment. Essentially simultaneously, the second sheath wire 10 is unwound from a second roll and left untreated. The second sheath wire 10 is therefore not heat treated. Essentially simultaneously, the third sheath wire 11 is unwound from a third roll, the fourth sheath wire 12 from a fourth roll, the fifth sheath wire 13 from a fifth roll, and the sixth sheath wire 14 from a sixth roll. Further sheath wires 15, 16, and 17 are also unwound from their respective rolls. The sheath wires 9, 10, 11, 12, 13, 14, 15, 16, 17, which are thus unwound from their rollers, are twisted together around the core 4 and together with the core 4 form a wire rope 3.This wire rope 3 forms the supporting core 2 of the music string 1.

[0085] Subsequently, at least one first winding element is wound helically around the string core, forming the first winding layer 19.

[0086] This allows the Young's modulus and / or the tensile strength and / or the springback ratio of a wire to be specifically and predictably influenced. In particular, this makes it possible to achieve that two sheathed wires 9, 10, 11, 12, 13, 14, 15, 16, 17 made of identical materials each exhibit predictably different springback ratios. This makes it easy to ensure that the first length section 37 extends to individual areas of the musical string 1 by performing the heat treatment only section by section on the unwound sheathed wire 9, 10, 11, 12, 13, 14, 15, 16, 17.

[0087] Three heat treatment processes have proven particularly advantageous in the manufacture of musical strings. Each of these processes has different effects on the treated sheath wires 9, 10, 11, 12, 13, 14, 15, 16, 17. These effects are also material-dependent, which is why it is particularly important to select the appropriate process together with the choice of material for the sheath wire in question.

[0088] According to a first preferred embodiment, it is provided that the first longitudinal section 37 of the first sheath wire 9 and / or at least one further sheath wire 10, 11, 12, 13, 14, 15, 16, 17 is stress-relieved during heat treatment.

[0089] According to a second preferred embodiment, it is provided that the first longitudinal section 37 of the first sheath wire 9 and / or at least one further sheath wire 10, 11, 12, 13, 14, 15, 16, 17 is hardened during the heat treatment.

[0090] According to a third preferred embodiment, it is provided that the first longitudinal section 37 of the first sheath wire 9 and / or at least one further sheath wire 10, 11, 12, 13, 14, 15, 16, 17 is tempered during heat treatment.

[0091] The following are principles for understanding and interpreting the disclosure in question.

[0092] Characters are usually introduced with an indefinite article "ein, eine, eines, einer". Unless the context indicates otherwise, "ein, eine, eines, einer" should therefore not be understood as a numeral.
