The invention relates to accessory and component and actuating parts, respectively, for musical instruments.
The invention aims at constructing accessory and component and actuating parts, respectively, for and of musical instruments, respectively, in such a way that said parts will interfere with the vibration behaviour and hence the sound emitted by those instruments as little as possible but will have a positive impact. Furthermore, the durability and handling of the instruments are to be improved.
These objects are achieved by designing said parts according to the characterizing part of claim 1. According to the invention, it is achieved that the tone of an instrument is preserved with the upper harmonics and brilliance and carrying capacity are increased; the positive result is well audible. The response of the instrument as well as the brilliance and carrying capacity of the tone are improved, since those parts cause virtually no damping of vibrations and upper harmonics.
Due to the features of claim 3, the advantages are achieved even more explicitly and an almost optimal sound quality, especially sound brightening, is obtained. Furthermore, the parts are wear-resistant, inert, they do not cause allergies and are durable.
The design according to the invention is particularly advantageous for the components of musical instruments indicated in the characterizing part of claim 9.
In the drawings, examples of parts designed according to the invention are indicated, however, it goes without saying that only the designations of said parts are relevant for the scope of the invention rather than the actual depiction of these parts, which might be created also in a modified form by a person skilled in the art.
The invention is explained in further detail below by way of the individual parts, with reference to the drawing.
A fine tuner according to
The fine tuner illustrated in
The surfaces of the fine tuners according to the invention are non-abrasive because of the hard layers and the material does not cause allergies.
According to
The knurled nut and the knurled screw carry a flat knurl with a division of 0.5 mm. A threaded stem is placed onto a milled U-profile 1, which threaded stem has a bore for the knurled screw and a bore for the thread nut 6. The external thread of the stem carries the thread of the knurled nut and, on the other end of the U-profile 1, there is a bore with an indentation for the microscrew representing the articulation. On one side, the lever 2 has a slot which ends in the bore 10 and serves for receiving the string, and in the bend it has a bore or recess 7, respectively, for the microscrew 5. A shuttle-shaped recess 8 which serves for guiding the knurled screw is milled into the other end. The slot 9 has variable dimensions, depending on the string to be hooked in.
These advantages generally apply to all parts designed according to the invention.
The hard layers can be applied in several identical or different layers to the surface of the alloys, whereby the vibration behaviour of the material is influenced in a well audible and pleasant way.
The string ball can have a cylindrical or oval bore 14 as illustrated in
a, 4b and 4c show a tailpiece fastener 20 and a fixing part 21 for string instruments. At the narrow end of the tailpiece 22, the tailpiece fastener 20 is put through the two holes 23 in the wood 3 and subsequently through the two holes 24 of the fixing part 21 and is then bent up and twisted. According to the invention, the tailpiece fastener 20 and the fixing parts 21 are produced from titanium or from the indicated titanium alloys—if need be, provided with at least one hard layer—whereby the transmission of impulse vibrations and upper harmonics is improved. Since the tailpiece fastener 20 and the fixing part 21 constitute the direct transmission point of the impulses, vibrations and upper harmonics, it is essential not to dampen said impulses, vibrations and upper harmonics.
The diameter of the tailpiece fastener 20 and of the fixing part 21 is adjusted to the instrument. The alloys can be used particularly well for the intended purpose because of their density, their tensile strength and their modulus of elasticity.
a and 5b show a wolf eliminator 25 for string instruments. In the wolf eliminator according to the invention, the two halves of a collet chuck 26 are applied axially (
Pure iridium and pure tantalum, respectively, is used because of the high density of these materials and due to their good sound conductivity.
Since the collet chuck is the direct transmission point of the transmitting string to the mass of the wolf eliminator, it is essential not to dampen the impulses, vibrations and upper harmonics of the string as a result of a direct contact of the string with the wolf eliminator. The diameter of the inner bore 29 of the collet chuck 26 is adjusted to the string. The positive result is well audible, since the response of the instrument during the wolf tone as well as the brilliance and carrying capacity of the tone are substantially improved, since soft materials such as copper, rubber, caoutchouc, plastic or the like cause virtually no damping of impulses, vibrations and upper harmonics. As with the other parts produced according to the invention from titanium or from the titanium alloys according to the invention, respectively, a coating of hard layers can optionally be applied by anodic oxidation and/or age hardening.
In order to save on weight, it may be provided that the shaft 31 is thinned between the pegbox walls 33, if necessary.
The peg shaft 31 made of titanium or a titanium alloy is glued with a conical surface to the wooden peg having a conical bore. Said conical surface has two grooves 34 in the form of a conical left-hand and an overlapping conical right-hand thread in order to ensure positive bonding. The two grooves are not completely cut as threads with a gradient of 1 mm.
The bearing surface 2 of the peg shaft 31 exhibits a conical fine thread 34 with a gradient of 0.08 mm in order to prevent loosening during the tuning of the peg, i.e., the peg tightens automatically, whereby not only the support of the peg but also the vibration transmission of the peg to the instrument is promoted. Thus, there are two pegs with a conical right-hand fine thread and two pegs with a conical left-hand thread for one instrument. The peg shaft end is provided with a wooden cap 30 for optical reasons.
a and 7b show a tuning peg 40 for keyboard instruments. Said tuning peg consists of a metal rod 41 which carries a square 42 on one end and a single-start or multi-start fine thread 43 on the other end. In the area between the thread 43 and the square 42, a hole 44, the so-called string hole, 44, is formed. With keyboard instruments, the tuning peg 40 is inserted or driven, respectively, into the pin block, after a slightly smaller hole has been pilot-drilled into the block in order to subsequently wind the strings onto the tuning peg and to be able to tighten, i.e. tune, them. Instead of the iron alloys which have previously been used for such tuning pegs, the alloys according to the invention or titanium, respectively, are provided, if need be, comprising hard layers. In this way, the advantages are achieved which have already been achieved in connection with the other parts of the musical instruments. The diameter and length of the tuning peg 40 are adjusted to the respective keyboard instrument.
In contrast to conventional tuning pegs, the fine thread 43 exhibiting the specific thread profile is not cut or case-threaded but rolled or milled. This has the decisive advantage that the surface is not rough but very smooth and free of burrs and edges and that hence the wood is not machined but only displaced during the knocking-in process, whereby a far better support for the tuning peg is achieved, even if the tuning peg is replaced frequently.
The mouthpiece 60 is a rotationally symmetrical pivoted part made of titanium or an alloy indicated according to the invention, comprising an edge 61, a pot 62, a heart 63, a soul 64 and a shaft 65. The bore is referred to as a rod or shaft bore 66.
A ring 67 can be inserted in the mouthpiece; said ring 67 could also be attached or wound, respectively, onto the exterior of the heart 63 and the soul 64, respectively. Preferably, the ring 67 is hot-pressed so as not to interfere with the vibration transmission. The titanium or alloys used, respectively, is/are preferably provided with hard layers and can therefore be set into vibration more easily and produce a brilliant tone rich in upper harmonics. This kind of tone formation is improved by the inserted ring.
The ring 67 must not be glued but, as already mentioned, has to be hot-pressed after having been inserted; a ring wound on from the outside must not be glued but has to be shrunk on.
In the following, a bridge pin for keyboard instruments is described without a separate drawing. A bridge pin according to the invention consists of a round metal rod (length approx. 10 to 15 mm, diameter approx. 2 mm) which has a tip on one end and is composed of titanium or an indicated titanium alloy, if need be, provided with hard layers. In a keyboard instrument, the bridge pin has the function of transmitting the string's vibrations directly to the instrument. The diameter and length of the bridge pin are adjusted to the respective keyboard instrument.
A string designed according to the invention (not illustrated) is produced from titanium or from one of the indicated alloys, respectively, if need be, coated with hard layers. In addition, the string can be electroplated with rhodium or platinum.
The string according to the invention is a non-gimped or ungimped string, respectively, which is provided with a string ball on one end and is inserted into a peg on the other end in order to be clamped onto an instrument in this manner. A string designed according to the invention is far more prone to vibrations and facilitates the response of the instrument. The diameter of the string and the required tension as well as the length are adjusted to the respective instrument. By coating the base material and the hard layers respectively, which have been applied if necessary, with a material of higher density such as rhodium or platinum, the tone becomes more brilliant.
The fret for plucked instruments illustrated in
In order to improve the response, the carrying capacity and brilliance of such instruments, the sound piece or bell mouth, respectively, is produced from titanium or a titanium alloy, if need be, coated with at least one hard layer and optionally anodized or designed in terms of colour and hardness, respectively, via heat treatment.
A chin holder screw comprises a curved setscrew 76 with two right-hand threads, an inside thread part 77 with a right-hand thread 78, a left-hand thread 79 as well as at least one transverse bore or transverse bores 80, respectively, and a foot 81 with a left-hand thread 79 as well as a clearance 82 for the bottom edge. In order to protect the instrument, the foot 81 and the chin holder 83 are plated with cork 84.
In contrast to conventional materials of brass or steel, which, if need be, are nickel-plated or gold-plated, titanium or titanium alloys are used at best with hard layer coatings. This involves improvements with regard to wear, allergic behaviour as well as the transmission of impulses, vibrations and upper harmonics.
Furthermore, the chin holder screws according to the invention have only three radial inside-thread part bores instead of four like conventional chin holder screws, whereby damage to the ribs is prevented during assembly and disassembly. Furthermore, the internal threads, i.e. the left-hand thread and the right-hand thread, are covered by an initial clearance of the thread in the inside thread part, thereby preventing the musician's hair from getting entangled.
The plectrum 90 is a roughly triangular flat part whose edges 91 are chamfered or rounded. In its centre, the plectrum carries a grip part 92 attached to both sides. Said part can be milled, embossed or cast-on. The plectrum 90 is produced in various strengths, depending on the respective variation and tone.
Such mechanisms may be designed or used, respectively, for a single string at a time or also for several strings. A mechanism constitutes a device located on the pegbox of a plucked or string instrument, respectively, in particular a contrabass, which usually is permanently mounted on the instrument and is used for tightening and tuning the strings, mostly via a worm gear. Such a mechanism 95 generally comprises a base plate 1, a shaft 2 with a string hole 6, a worm drive 3 with a wing grip 4 and a worm wheel 5. At least the shaft and advantageously at least one further part are produced from titanium or from titanium alloys according to the invention, respectively, if need be, comprising hard layers and optionally treated thermally.
Connecting the slide 105 designed in this way with the other components of the trombone or with further duct parts 100, respectively, is feasible by laser welding or soldering.
The period of vibration of such a lamina 111 can be extended by inserting or attaching, respectively, heavy metal parts 112, especially made of tungsten and/or iridium and/or alloys of these metals, on both ends of the lamina. The support or fixing of the lamina 111 with clamping parts 114 in these grooves 113 formed on both vibration nodes, as illustrated on the left-hand side of
Tongues for accordions, harmonicas and mouth organs of all kinds can be produced from titanium, in particular titanium grade 5, in particular the indicated titanium alloys, if need be, provided with hard layers of the indicated kind, whereby a far better quality of sound is created for the reasons already indicated. The result is, above all, precision and poignancy of the tongue and consequently a fast response; if the instrument is played softly, the abundance of upper harmonics need not be relinquished. Due to the low E-modulus, the harmonica has a longer sound.
The same also applies to tongues used for musical clocks or similar instruments, wherein the tongues which have previously been produced from brass alloys can be replaced by tongues of the kind according to the invention. At the same time, a tongue break is virtually ruled out due to the design according to the invention of such tongues.
Sheets for woodwind instruments of all kinds, in particular for saxophones, oboes, can be produced from titanium, in particular titanium grade 5, or from the indicated alloys, respectively, if need be, comprising hard layers. The wear resistance of such sheets is increased; the precision and poignancy of the tongue and hence a fast response and the possibility to play softly, without having to relinquish the abundance of upper harmonics, are thus feasible. At the same time, the material used is inert and non-abrasive and does not cause allergies. Furthermore, common reeds change their vibration behaviour due to moisture, especially saliva and exhaled air. In contrast to reeds, the sheets according to the invention are resistant to moisture and corrosion. At the blade, the sheets according to the invention are far more sharp-edged than reeds, and the carving of the reeds can be omitted.
A bridge according to the invention comprises bridge supports made of titanium or the indicated titanium alloys, respectively, optionally coated with hard layers.
In the design according to the invention of the bridge supports or of a bridge, respectively, a string is prevented from caving in and hence, on the one hand, the string is allowed to vibrate freely and, on the other hand, the distance from the string to the finger board is not reduced.
a is schematic illustration of a mute 125 for string instruments. Such mutes 125 are placed onto the bridge 126 of the string instrument when playing said instrument. Due to the design according to the invention of such mutes, the advantages are achieved which have already been described for the previously described parts.
According to
Such a play mute or practice mute 127, i.e. with or without an insert 128 acting as a weight, is located firmly especially due to the low E-modulus of the metals used and does not become detached easily, not even as a result of vibrations.
Bow windings (not illustrated) for string bows can be designed in the manner according to the invention; instead of solid wires made of nickel silver, silver or gold, wires or strips made of titanium or titanium grade 5 or the corresponding alloys, respectively, if need be, in combination with hard layers, are used on the bow rod for protecting the rod and for providing safe support. The wear resistance, the corrosion resistance and the skin tolerance of these materials are important especially in this case. The bow winding, in particular the wire, can be designed in a round or semi-oval fashion or as a milled or unmilled flat strip or plait. Due to the low density of the materials used, the balance of the bow is influenced positively.
Organ pipes (not illustrated) are produced according to the invention from the indicated materials, i.e. titanium or titanium alloys, if need be, coated with at least one hard layer, whereby corrosion resistance is provided, and—in contrast to conventional pipes consisting of soft materials—stability of the tone pitch is ensured.
The wear resistance and corrosion resistance of the bow face 131 made of titanium or a titanium alloy is almost boundless. In addition, the material and the coatings are inert and non-abrasive.
Due to the low density, the balance of the bow will also be influenced positively. A wedge is pressed into the face which is subjected to enormous strain against which titanium or titanium alloys offer sufficient resistance. The axial reflection of the rod is promoted by the high strength and sound conductivity of titanium without weighing too heavily in the head area.
A tailpiece 135 as schematically shown in
The frog ring is subjected to enormous strain during the attachment of the hairs, since the hairs are inserted in the ring with a wedge; titanium and the titanium alloys used, respectively, offer enough resistance toward said strain. The axial reflection of the bow rod is promoted by the high strength and sound conductivity of titanium or of the alloys used, respectively, without weighing too heavily in the frog area.
According to the invention, the bell 160 and/or the clapper 162 is/are produced from titanium or from a titanium alloy provided according to the invention, if need be, coated with at least one hard layer. As with all other previously described parts, a heat treatment can be provided. Apart from the lightness of such a bell 160, it can easily be set into vibration and has a brilliant tone rich in upper harmonics. The duration of the chime and of the lingering sound, respectively, can be doubled, and the sound volume of the bell increases substantially. With the employed titanium alloy or titanium, respectively, the risk of fracture is much smaller than with the bronze or brass which is usually used.
Instead of titanium and titanium alloys, tungsten and/or iridium or alloys of these metals, if need be, also platinum-iridium alloys, are used as materials for the string bow screw. The reason therefor is that the end of the bow rod receives the screw in an axial manner and, due to the high density of the screw (of approx. 17.5 to 22.65 kg/dm3), permits a far more intensive axial flection of the bow rod than in a situation with less weight applied. In addition, the balance of a lightweight bow, especially of antique French bows, can be modified and adjusted very easily by replacing the screw. If the heavy metal alloy of the screw exhibits an appropriate sound conductivity and hardness, the upper harmonics are not damped and the bow has a fuller and louder tone and the grip of the bow hairs and hence the playability as well as slightly trembling bows can be offered to a user in improved versions. The vibration behaviour of the bow screw is influenced in a well audible manner by one or several superimposed layers such as TiN, WC/C, CrC, CrN. These layers are applied onto the screw via PVD processes and reduce the coefficient of friction to a substantial extent, whereby the nut obtains a longer durability.
A tuning fork 176 according to the invention, as illustrated, for example, in
The tuning pipes 177 schematically illustrated in
The wooden endpin part is inserted into a conical hole in the bottom block of a cello or contrabass in order to then produce the tension of the strings on an instrument by means of the tailpiece fastener, the tailpiece and the strings. Presently, all wooden endpin parts (
In contrast to conventional endpins (
Normally, the rod 184 of the endpin is inserted into a cylindrical hole and is fastened with the wing set screw 185 which has the opposing thread in the ring 186.
In the invention, the wooden part receives the rod 184 in a cone 187. In this way, an equally firm seat of the rod is produced, irrespective of moisture or dryness, which seat can also be bent (
The rod 4 is likewise retained by a wing set screw 185 which presses down on a small area 188 milled into the cone. The invention has the disadvantage over conventional endpins that the rod can no longer be lowered into the instrument and hence is no longer height-adjustable in the wooden part, but the acoustic result is unmatched.
Height adjustment is effected at the tip of the rod by screwing or unscrewing the tip which is clamped by a slotted collet chuck 189 and a spigot nut 190.
In addition, acoustic advantages are provided if the material wood or plastic for the wooden endpin part, the rod, the ring, and the set screw is replaced by titanium or a titanium alloy, due to the vibration fatigue limit and density of the material.
If titanium or a titanium alloy is used for one or several part(s) on an endpin, it is occasionally feasible to provide coatings of titanium nitride, tungsten carbide carbon, chromium carbide or chromium nitride in order to differentiate the sound.
In case of the wooden endpin part according to the invention (
Omitting the collar 182 has two decisive advantages, first of all, it is possible only without a collar to provide firm support for the conical shaft 181 of the wooden endpin part, as the insertion is not limited by the collar and, secondly, the parallelism of the tailpiece fastener to the ribs is possible only without a collar. The firm seat of the conical shaft 181 is necessary for a better vibration transmission and a better support, and the parallelism of the tailpiece fastener to the ribs makes sure that the cover of the instrument is not upset excessively and the bottom of the instrument is not tightened excessively.
Especially in case of antique celli and contrabasses, the protruding bottom edge and cover edge is of course worn out during use, necessitating that distance “x” be reduced.
This results in a far more freely vibrating instrument, having a larger tone which is richer in upper harmonics. The instrument can also be played more easily due to an easier response.
In addition, the entire instrument, in particular the bottom and the cover, is deformed far less over time.
Presently, all buttons (
The button 200 is also provided with a ball 205 as a decoration. In contrast to conventional buttons (
In addition, acoustic advantages are provided if the material wood or plastic for the button is replaced by titanium or a titanium alloy, due to the vibration fatigue limit and density of the material. If titanium or a titanium alloy is used, it is occasionally feasible to provide coatings of titanium nitride, tungsten carbide carbon, chromium carbide or chromium nitride in order to differentiate the sound.
In case of the button according to the invention (
Omitting the collar 204 has two decisive advantages, first of all, it is possible only without a collar to provide actual support for the conical shaft of the button, as the insertion is not limited by the collar 204 and, secondly, the parallelism of the tailpiece fastener 203 to the ribs is possible only without a collar 204.
The firm seat of the conical shaft 206 is necessary for a better vibration transmission and a better support, and the parallelism of the tailpiece fastener 203 to the ribs 208 makes sure that the cover of the instrument is not upset excessively and the bottom of the instrument is not tightened excessively.
Especially in case of antique violins and violas, the protruding bottom edge and cover edge is of course worn out during use, necessitating that distance “x” be reduced.
This results in a far more freely vibrating instrument, having a larger tone which is richer in upper harmonics. The instrument can also be played more easily due to an easier response.
In addition, the entire instrument, in particular the bottom and the cover, is deformed far less over time.
A valve 210 according to the invention for brass instruments according to
In general, the material used and the coatings, respectively, are inert and non-abrasive as well. The hard layers do not only contribute to an increase in strength and stability but also influence the vibration behaviour of the material in an audible and pleasant way. Due to the poor heat conductivity of the materials used, is it possible to play the instrument with ease also in cold weather and/or in the open air. It is likewise possible to influence undesired vibrations on the cap using material combinations such as tungsten and/or iridium and/or alloys of these metals by applying them appropriately. It is important especially for valves 210 and for trombone slides and also in general that, if titanium grade 5 is used in all areas where titanium rubs or runs on titanium, rubbing is to be avoided by coating or material pairing with cold-hammered bronze for bearings and bushes, and not by grease, since grease would dampen the transmission of vibrations. Agglutinations are to be avoided as well.
The valve 210 according to the invention is usable for all kinds of valves or valve machines, regardless of whether the valve is a sliding valve (
In
Commercially available tailpieces 222 for string instruments are made of wood and are shown in
In this way, the string 225 is bent above the small ring 227 and on the edge 228. The invention is based on the fact that, in the tailpiece (
In this way, the string is not unnecessarily bent twice but runs directly from the abutment of the string ball to the bridge.
As far as the conical groove 230 is concerned, it must be made sure that the string is exposed, since otherwise it might rattle.
The wood used is ebony, boxwood or rosewood.
If a fine tuner is required on one or several strings, the blind hole must be drilled through and a fine tuner, preferably made of titanium or a titanium alloy, is to be used.
The playability and quality of sound are audibly improved, since the vibratory characteristics of the ball and of the string are not hampered but transferred via the bridge directly to the cover.
Commercially available bridge saddles and neck saddles for plucked instruments are manufactured from ebony, bones, ivory or plastic.
If the bridge saddle 235 produced in
The wear resistance and corrosion resistance of the saddles 235, 236 made of titanium or a titanium alloy is almost boundless. In addition, the material and the coatings are inert and non-abrasive. The vibration behaviour of the saddles is influenced in a well audible and pleasant way by one or several superimposed layers such as TiN, WC/C, CrC, CrN.
As a result of the abundance of upper harmonics of titanium saddles, the tone is better and moreover the tone is audible for a longer period of time due to the good vibration behaviour.
It is likewise possible to produce the saddles from quartz glass (silicon oxide, SiO2), since, similarly to titanium grade 5, a long-lasting vibration with a very low damping effect is provided.
Both titanium or a titanium alloy and quartz glass are highly polishable, involving a high surface quality in the string grooves 237 and, associated therewith, a long durability of the string.
The playability and quality of sound are audibly improved, since the vibratory characteristics of the string are not hampered but transferred via the bridge and the neck directly to the instrument.
A commercially available wooden bridge 240 for plucked instruments, which is illustrated in
The invention is based on the fact that, in the bridge 240 according to
In this way, the string 242 is not unnecessarily bent but runs directly from the abutment, the string ball or the knot to the saddle 247.
Regarding the sloped larger bore 246, it must be made sure that the string 242 is exposed, since otherwise it might rattle.
The wood used is ebony, maplewood or rosewood.
The playability and quality of sound are audibly improved, since the vibratory characteristics of the ball 243 and of the string 242 are not hampered but transferred via the bridge 247 and the bridge saddle directly to the cover.
