Description

Be used for the improved string configuration of musical instrument

Technical field

The present invention relates generally to the stringed musical instrument structure, more particularly, relates to a kind of improved string supporting configuration and bridge structure that improves the tonequality of these musical instruments.

Background technology

Total assembling structure of stringed musical instrument is well-known in this technical field.For example, in the configuration of piano type, there are many strings to be stretched in a string attachment structures, the two ends of a plate for example, when being subjected to the strike of a hammer, each root string all can vibrate.String defines audio frequency, and some kinetic energy that hammer moves are converted into vibrational energy, is included in the oscillating component on the plane that is parallel and perpendicular to described plate.The piano-style string normally is arranged to level (as grand piano) or vertical (as upright piano), and is subdivided into three main cohorts usually: bass, low high pitch and high high pitch.Bass is usually directed to bass tone (lower pitchednotes), and high pitch is usually directed to high pitch tone (high pitched notes).In the configuration of a piano type, three strings that are used for the high pitch tone are generally arranged, two strings that are used for low high pitch tone, a string that is used for bass.One or two or three becomes one group string to be commonly referred to as " same tone ".Each with tone or tone, is typically provided with a key.A piano has 88 keys usually, thereby between the C8 tone of 27.5 hertz A0 tone to 4186 hertz 88 tones is arranged at least.

In a kind of piano type configuration, string matches with a bridge structure, and the bridge structure is sent to a sound structure for amplifying or soundboard with the vibrations of strings energy.Usually, the bridge structure is to be arranged to transverse to each string, and comprises that the bridge pins (some musical instrument, for example harpsichord generally only is provided with a bridge pin) of be used for every string two band angles, this two bridges pin are attached to a curved surface fin with an end face.Each string all has one and is positioned at the structural supporting-point of bridge, is known as point (speaking) or vibration length end points sometimes.These two pins normally are mounted to has specific angle, makes string prop up bridge downwards, and the side props up pin.For avoiding some undesirable performance characteristic, for example they can move apart the supporting-point of appointment on the bridge structure when string is subjected to exciting, and the bridge pin of this band angle is considered to necessary in the past always.In fact, also avoiding pin not have the installation of the sort of carelessness of enough angles, because also can cause similar above-mentioned problem like this.

The support relation of below and side also helps their vibrational energy is passed to the bridge structure between each string and the bridge structure, and partly defines mechanical attachment between the two.Because each string is the important reservoir that is used for storing vibrational energy, so although also be not to understand fully to its reason and interaction relationship, amplitude that string is excited and mode and boundary condition are very important for the tone of determining a string.For example, in a piano, string normally excites by a bump with hammer of certain stroke speed, and described stroke speed depends on that the pianist imports the size of power on piano key.It is contemplated that the coupling method of the physical hardness of stroke speed, hammer and density (and felt coverage) and string and bridge structure defines the initial tone of string.

The tone of string often is limiting with tone and die-away time by string.When a string was excited (for example being subjected to the strike of a hammer), its can vibrate under a basic frequency, and this basic frequency is to be determined by vibrations of strings or sounding length, the tension force of string, the quality of per unit length string.String also can vibrate under the integer multiple frequency of basic frequency, and this frequency often is known as overtone, in other words, is to produce a kind of " vitrifacation " sound that is helpless to discernable pitch.The relative intensity of basic frequency, overtone or amplitude often are known as music with vitrifacation sound, it defines string and tone.The amplitude of basic frequency is big more, overtone more little (for example, whether in high pitch, low high pitch or bass range, determining that this overtone is 5 to 10 integral multiples of basic frequency according to string usually), and tone is just clear more, desirable; Otherwise the frequency that produces vitrifacation sound is big more, and their amplitude is high more, and then the desired level of tonequality is just poor more.

Except string with tone, the rate of decay of the extra amplitude of the stimulating frequency of string (for example basic frequency, overtone and other correlated frequency) also is very important when determining the tonequality of a string.Usually, the time of decay is long more, and then tonequality is good more.Better is that the die-away time between each tone-tone is comparatively even, can obtain harmonious mutually multiple tone when playing.For example, in general piano type configuration, sometimes be difficult to realize a kind of so good balance, that is: make above pitch (the tone C5 to F6 of the 5th octave group and keyboard, so-called melody scope) keeps the sufficiently long time (promptly, have sufficiently long die-away time), and lower octave scope (tone C1 to C5) is intrinsic than long die-away time.

Though bridge structure in the past can realize excellent function to its purpose of design, often and always wish a kind of improved bridge structure that realizes the additional work advantage can be provided.For example, thus hope can provide the string configuration that makes a kind of die-away time that prolongs string from the fine fusion of (juxtaposed) tone arranged side by side of different range piano qin sound.Also have beneficially, provide a kind of energy improved string configuration, it can reduce the vitrifacation sound relevant with a tone, and can produce a tone more clearly.The invention provides a kind of so improved string configuration, it can provide the design with above-mentioned tone advantage and feature.

Summary of the invention

A kind of string configuration that is used for musical instrument, described musical instrument comprises that at least a string and is used for string is connected in the bridge structure of a pronunciation component.Described bridge structure has a bridge surface and a supporting-point edge.One to be arranged on the structural first bridge pin of described bridge tangent with the supporting-point edge at least, and be basically perpendicular to described bridge surface, thereby make string can contact the supporting-point edge and the first bridge pin simultaneously at bridge structure place.Also be provided with the second and the 3rd bridge pin on the bridge structure, they lay respectively at first bridge pin back distance one second bridge pin spacing vertically, and the second bridge pin back is vertically apart from the position of one the 3rd bridge pin spacing.Second is oriented to become one second pin orientation acute angle and the 3rd to sell with described bridge surface with the 3rd bridge pin is orientated acute angle.Described string comprises that first side of described first pin of a contact contacts second side of the described second and the 3rd pin with one, described pin orientation acute angle is all near described second side of described string, so that the described second and the 3rd pin deflection, and make described string and described supporting-point edge have the lower support contact relation.

In some preferred embodiment, preferably, the second and the 3rd bridge pin spacing is in the scope of about 1mm to 1cm.The second and the 3rd bridge pin can also have certain orientation, promptly becomes one second pin angle of deviation with respect to the first bridge pin, becomes one the 3rd pin angle of deviation with respect to the second bridge pin.In preferable configuration, the second and the 3rd bridge pin angle of deviation is for the first and second bridge pins in the scopes that approximately-45 degree extremely about 45 is spent.

Embodiment

To describe preferred embodiment of the present invention in detail below, these examples illustrate that in conjunction with the accompanying drawings label identical in the accompanying drawing is represented components identical.Fig. 1 is certain inner a part of plan view from above of an exemplary piano 20 (a for example grand piano) manufactured according to the present invention, and the roughly feature of this piano is familiar with person skilled in the art.Though each preferred embodiment that will describe herein is particularly suitable for being used in the grand piano configuration, the present invention also can be applicable to various stringed musical instruments, for example upright piano, harpsichord, clavichord, guitar, mandolin, violin etc.

Preferably, piano configuration 20 comprises: many strings (for example 28a, 28b, 28c, 28d, 28e, 28f), the soundboard 30, near described each string that has tail piece 22, the tensioning of near-end 24 and terminal 26 and pass across tail piece 22 is used for described each string is connected in the bridge structure (for example, be used for the 32a of high pitch string and be used for the 32b of bass string) of soundboard 30.Clearly visible from Fig. 1, an exemplary high pitch tone preferably includes string 28a, 28b and the 28c that forms one first Prime 34a, and an exemplary low high pitch tone preferably includes string 28d and the 28e that forms one second Prime 34b.Bass tone shown in the figure preferably includes a single string 28f who forms one the 3rd Prime 34c.For clarity sake, all the other strings to grand piano 20 just repeat no more.

Each root string (for example 28a, 28b, 28c, 28d, 28e, 28f) roughly extends through tail piece 22 diagonally, and is made of the line 40 with mechanical length (for example M), as clearly shown in Figure 2.String preferably terminates in near-end 24 by tuning pin 42, terminates in end 26 by bolt system pin 44, and can be attached to tuning pin 42 and bolt system pin 44 in mode known in the art.Though every string can be that the different line 40 of M constitutes by mechanical length, in a better embodiment, adjacent string can be by constituting with single line, thereby mechanical length M defines two strings (referring to Fig. 3).In the configuration of this being commonly referred to as " annular string continues ", an end of line 40 stops by the first tuning pin 46a, and forms the first string 48a through a bridge structure (32a for example shown in Figure 1 or 32b).Then, on bolt system pin 44, also terminate in tuning pin 46b place after the process bridge structure once more with single line 40, thereby form the second adjacent string 48b.Therefore, be adjacent tuning pin 46a and 46b, rather than tuning pin and bolt system pin can limit the mechanical terminating point of line 40.The first string 48a and adjacent string 48b can keep their pitches separately, because line has certain force of strain and rigidity when the pin 44 places bending of bolt system.Every string is all preferably made by high-intensity steel, and can uncover, or is coated on one or more layers and covers in line or other material, and each clad all is that the mode with a kind of multi-circle spiral flow is wound on the inner core.

Clearly visible by Fig. 4, tuning pin 42 preferably passes tail piece 22 and enters in the piece 50 of consigning that is attached to tail piece 22.One end of line 40 is wound on the tuning pin 42, thereby by regulating the tension force that tuning pin 42 can increase or reduce line selectively, and then regulates or the basic frequency of the string that " tuning " formed by line 40.In this manner, forming together, each string of tone (for example 34a, 34b and 34c) can correctly keep each other harmoniously.

Preferably, each bridge structure is attached to (for example by glueing joint) soundboard 30, make this unitized construction mechanically relative with the downward bearing load that produces by the string of tensioning, and serving as the acoustic radiating member of this string configuration (for example piano 20), some mechanical energy that is about to string and bridge is transformed into acoustic energy.Soundboard 30 is preferably made by sound wood (tone wood) with bridge structure 32a and 32b, or solid, or stacked.Soundboard is used a kind of vegetable cork usually, and for example spruce wood is made, and bridge then is by hardwood material, and for example maple or beech are made.

Clearly visible by Fig. 2, every vibrations of strings length or sounding length S have first and second end points.First end points is that the deflection element 52 by near-end 24 places provides, and uses making string that enough deflections or effective deflection take place.In a preferred embodiment, the deflection element can be the overlap joint pin 54 that is fixed in tail piece 22, or well-known V shape pole (not shown) in the prior art.

Second end points can be provided by a bridge structure (for example 32a, 32b) at terminal 26 places, shown in Fig. 5 (bridge structure 32a) and Fig. 6 (bridge structure 32b).Each bridge structure preferably includes: one has the bridge fin 58 on bridge surface 60, and with the every first bridge pin 62a, the second bridge pin 62b and the 3rd bridge pin 62c that string is relevant.As shown in the figure, bridge surface 60 has a supporting-point edge 64 and back edge 66.The present technique field is well-known, is preferably limited second end points of string sounding length S by supporting-point edge 64 and first bridge pin 62a cooperation.The first bridge pin 62a preferably is positioned on the bridge structure (for example 32a or 32b), and at least a portion of the first bridge pin 62a and supporting-point edge 64 are tangentially intersected.Be more preferably, the first bridge pin 62a is positioned on the bridge structure, and make supporting-point edge 64 approach as shown in Figure 6 the first bridge pin 62a is halved, thereby every string (for example 28a, 28b, 28c, 28d, 28e and 28f) contacts with supporting-point edge 64, the first bridge pin in same plane is basically perpendicular to the longitudinal axis (for example P) of string 62a, as shown in Figure 7 and Figure 8.Owing to having guaranteed that the first bridge pin contacts with support edge or at least tangentially having intersected, so the every sounding length S of string at bridge structure place has only effective second end points.In order to ensure between each string and the bridge structure enough gaps being arranged, thereby make a string and contacting of the first bridge structure occur in 64 places, supporting-point edge, one first recess or otch 68a and each Prime (for example 34a, 34b, 34c) can be connected, this recess is arranged between leading edge 70 and the supporting-point edge 64.One second recess 68b is between trailing edge 72 and back edge 66, so that enough gaps are provided there, though this recess is not necessary.

The first bridge pin 62a preferably is orientated in the mode that is basically perpendicular to bridge surface 60 in its junction.Terminology used here " vertical substantially " means that the first bridge pin 62a is about 90 degree ± about 5 degree with respect to the angle A 1 on bridge surface 60.Be more preferably, angle A 1 is about 90 degree ± about 2 degree, preferably demarcates to be about 90 degree.Can believe that the orientation that the first bridge pin 62a is basically perpendicular to bridge surface 60 can provide a kind of tone with longer die-away time, and can send than the string of other the first not vertical substantially bridge pin 62a sound of " bright " more.Though to the mechanical attachment characteristic between each string, bridge structure 62a and 62b and the soundboard 30, and also not clear fully to the influence of tonequality, and be not subjected to the restriction of any certain principles, but can believe, realizable holding time that is stimulated string in the present invention disposes is comparatively effective, with a sounding length is that the comparable string that S and terminating in has a bridge structure place of non-vertical substantially first a bridge pin is compared, and string configuration of the present invention sensuously can obtain long holding time.Can also believe, compare, in the present invention disposes, one be stimulated the basic frequency of string greater than its first overtone with non-vertical substantially compared string.

Also have a kind of idea to be, the above-mentioned advantage of vertical substantially first a bridge pin comes from string at an increment that is roughly parallel to the initial vibration energy of (promptly being approximately perpendicular to the first bridge pin of the present invention) on the plane of soundboard.Because mechanical impedance in being parallel to the soundboard plane is relatively higher than perpendicular to the mechanical impedance in the soundboard plane, so a vibrations of strings energy dissipates in vertical plane in large quantities.So, can guess, utilize configuration of the present invention more energy can be assigned on the plane that is parallel to soundboard, the dissipation in vertical plane later on because more energy is got up by " storage " at first is so can produce a tone with longer die-away time.

One second bridge pin 62b and/or the 3rd bridge pin 62c can also be set on the bridge structure,, thereby make its Shi Buhui that is excited leave supporting-point edge 64 with anchoring one string mechanically.Preferably, the second bridge pin 62b can be arranged on after the first bridge pin 62a at a distance of one second bearing pin to space D 1 place, and with the first bridge pin in a straight line, shown in Fig. 9 A.In Fig. 9 A, for clarity sake (Fig. 9 A-9H only is for possible several positioned opposite of bridge pin 62a, 62b and 62c are described, is not the exhaustive of these layouts, and preferable bridge pin position is not described yet) removes the details of bridge structure.In better configuration, space D 1 is in the scope of the extremely about 1cm of about 1mm.

The second bridge pin 62b also can have second a pin angle of deviation (for example O1) with respect to the first bridge pin 62a, and is clearly visible by Fig. 9 B, 9D, 9F and 9H.Here said angle of deviation O1 be meant between be parallel to line 40 and pass the first imaginary line T1 of the first bridge pin 62a central point and pass the first bridge pin 62a and second imaginary line of the central point of the second bridge pin 62b between that angle, clearly visible by Fig. 9 B.Preferably, angle of deviation O1 is in the scopes of approximately-45 spending extremely about 45 degree (Fig. 9 B to Fig. 9 F shows a positive angle of deviation O1, and Fig. 9 H shows a negative angle of deviation O1).

Clearly visible by Fig. 8, there is one second pin angle of orientation A2 on the relative bridge of second bridge pin 62b surface 60, thereby the lower support state that every string is all remained prop up bridge surface 60, and the side bearing state that props up the first and second bridge pin 62a and 62b.In a preferable configuration, the angle of orientation A2 of the second bridge pin 62b be at about 65 degree to the scopes of about 80 degree, in other words conj.or perhaps at about 100 degree to the scopes of about 115 degree.Can believe that this lower support of every string and the relation of side bearing can prevent that string breaks away from supporting-point edge 64, and then prevent when a string is subjected to exciting, second end points skew of its sounding length S.In addition, every string is because of helping the vibrations of strings energy is sent to bridge structure and soundboard 30 with bridge surface 60 and first and second bridge pin 62a and 62b lower support and the side bearing state that keeps that offset.Though preferably the second bridge pin is oriented to angle A 2, make it be basically perpendicular to bridge surface 60 but also can contemplate, and a recess, groove or analog (not shown) can be set further, so that limit a string (28a, 28b, 28c, 28d, 28e and 28f) moving on the direction that is approximately perpendicular to bridge surface 60.

Preferably, the 3rd bridge pin 62c can be arranged on after the second bridge pin 62b at a distance of one the 3rd bearing pin to space D 2 places, and with the second bridge pin in a straight line, shown in Fig. 9 C.Though can believe, the physical location of the 3rd bridge pin is not very crucial, in a better configuration, the space D 2 of the 3rd bridge pin 62c and the second bridge pin 62b be at about 1mm to the scope of about 1cm.The 3rd bridge pin 62c can be oriented to and be basically perpendicular to bridge surface 60, perhaps preferably be arranged to respect to bridge surface 60 one-tenth one the 3rd pins angle of orientation A3 (Figure 10), if the 3rd bridge pin and the second bridge pin 62b (Fig. 2) are positioned at the same side of string, its angular range should be at about 65 degree between about 80 degree.Perhaps, preferably, if the 3rd bridge pin 62c and the second bridge pin 62b are positioned at the opposite side (shown in Fig. 9 G) of string, then the 3rd bridge pin can have one and the 3rd sells the angle of orientation at about 100 degree to about 115 degree scopes.

In a better configuration, the 3rd bridge pin 62c can be provided with the 3rd a pin angle of deviation O2 with respect to the second bridge pin 62c.Clearly visible by Fig. 9 E, said here angle of deviation O2 is meant the angle between imaginary line T3 and the T4, and imaginary line T3 is parallel or collinear with imaginary line T1, and imaginary line T4 passes the central point of the second bridge pin 62b and the 3rd bridge pin 62c.Preferably, angle of deviation O2 is in the scopes of approximately-45 spending extremely about 45 degree (Fig. 9 D and 9E show a positive angle of deviation O2, and Fig. 9 H shows a negative angle of deviation O2).

Though preferably on bridge structure 32a or 32b, three bridge pins are set for every string, but also can consider on the bridge structure, to be provided with other different pins configuration, two bridge pins (the first promptly vertical substantially bridge pin 62a and the second bridge pin 62b) for example only are set, and this does not depart from scope of the present invention yet.Similarly, also has such design: single first a vertical substantially bridge pin 62a only is set on the bridge structure, it is fixed by a pin to be every string, or leaves certain axial distance in bridge structure back other anchoring structure (not shown) is set.In this variation, be provided with the single bridge pin (not shown) that the function and the textural association of the first bridge pin 62a and the second bridge pin 62b (not shown) can be got up.For example a kind of so single bridge pin can be provided with a vertical substantially surface and a surface of being with angle, just as being all each independent bridge pin setting.

The bridge pin can be made by hard steel or analog, and it can be hollow, perhaps is more preferably to have applied copper, chromium or zinc so that wear-resisting solid steel.Though under the situation that does not influence the scope of the invention that is used for the piano configuration, the diameter of bridge pin can change, the diameter range of each bridge pin is preferably between 0.15cm to 0.25cm.In addition, though each bridge pin preferably has the shape of substantially cylindrical, other shape (for example oval, circular, square, triangle) and structure (for example single pin that function and/or the structure of the first bridge pin 62a, the second bridge pin 62b and the 3rd bridge pin 62c combined) can be arranged also.

The front is for purposes of illustration to detailed description that preferred embodiment of the present invention has been done, but these descriptions are not exclusive, does not also want the present invention is only limited to these patterns.Person skilled in the art are on basis described above, can also a lot of modification of design place and change, thereby each embodiment described above only is in order to describe the principle on surface best, and make the present invention can practical application, for specific musical instrument, various modification also are suitable for.Therefore, protection scope of the present invention is only limited by claims.
