Description
The present invention relates to a kind of violin, particularly a kind of high-sound-quality violin without noise.
Violin comprises four kinds on violin, viola, violoncello, Double bass, because they are except length thickness, the accordatura of volume size, string with range is different, its planform, ratio and pronunciation mechanism are all identical, have constituted a violin family thus.
Its version of traditional violin is: the scroll head on qin body top is provided with four pegs, and the bottom of the resonant tank of qin body Lower Half is provided with chord-drawing plate, four strings are connected between four pegs and the chord-drawing plate, the both sides of resonant tank are two recessed waists, be respectively arranged with f shape left side sound hole and right sound hole on the resonant tank on the panel at two recessed waist places, and the nightstool that is used to support four strings is positioned at the line of two sound hole mid points, and between the panel of nightstool bottom resonant tank and base plate, be vertically installed with a sound column, and, the ratio of the distance L 1 of this sound column above to the distance L 2 of resonant tank inward flange below and sound column to the resonant tank inward flange equals 0.724, i.e. L2/L1=0.724; Sound column is 0.580 to the distance L 1 of resonant tank inward flange top and the ratio of the distance L 1+L2 between the upper and lower inward flange of resonant tank, i.e. L1/ (L1+L2)=0.580; And the ratio of the distance L 3 of this sound column on the left of to the distance L 4 on case inward flange right side altogether and sound column to the resonant tank inward flange equals 0.730, i.e. L4/L3=0.730; Sound column is 0.578 to the distance L 3 in resonant tank inward flange left side and the ratio of the distance L 3+L4 between the left and right inward flange of resonant tank, i.e. L3/ (L3+L4)=0.578; It can be said that bright in existing violin the sound column strong point be the centre of oscillation to the distance of resonant tank upper and lower, left and right and up and down between the distance of total length and the left and right sides total length L2/L1 ≠ L1/ (L1+L2) ≠ L4/L3 ≠ L3/ (L3+L4) they be out-of-proportion.Usually when playing, draw string, will cause four string vibration pronunciations of fixedly accordatura, and conduct to panel, conduct to base plate through sound column again through nightstool when the horse hair friction of bow.The strong point of sound column is the centre of oscillation of panel and base plate, is transmitted to whole front panel and base plate thus, and air column sympathetic response in the case of striking a chord, and propagates at last in the ambient air, and just the hearing organ by people experiences.On physics, can produce the fundamental tone chord in the conduct vibrations process, the pass that homophonic high-frequency harmonic comprises high frequency even-order harmonic and high frequency odd harmonic, high frequency even-order harmonic and fundamental tone again ties up to the overtone that is called consonance musically, make the people feel to coordinate dulect, the pass of high frequency odd harmonic and fundamental tone ties up to and is called the cacophony journey musically, make the people feel ear-piercing and uncomfortable, be called noise traditionally again.Sound wave conduct vibrations on out-of-proportion distance is called nonsynchronous conduct vibrations physically in the violin of said structure, and the high frequency even-order harmonic overtones of in this process, coordinating in a large number except the meeting generation, also can produce a spot of inconsonant high frequency odd harmonic noise, thereby influence violin tonequality.At present; although people are to be top grade with the seven-stringed plucked instrument in some ways similar to the zither honor; as: the elaboration of once choosing ten violins in the Italian renaissance epoch; now only search out three, wherein one the British empire museum of existing Britain, two existing Italian National Museum; and protected with the constant temperature oven of bullet proof glass system; it is priceless, and now spread alive Amati, Stradivari and melon how in the violin of three great master's systems have 2,000 approximately, every value is the highest at 20,000,000 Renminbi.And set up the manufacturing technology of many violin research institution Research on Mining seven-stringed plucked instruments in some ways similar to the zither in various countries, attempt is duplicated the radiance of seven-stringed plucked instrument in some ways similar to the zither in the past with modern high-tech means, but viol has the shortcoming of above-mentioned violin equally, each family that just makes the qin great masters all has their handed down from the older generations of the family exhausted key rarely known by the people can cover its noise to make it reach dulect by every possible means as far as possible, moreover, the long age also can make viol in air through over a long time oxidation, wherein colloid and wooden meat composition have been cut down, stayed solid xylogen, increase vibration performance, also significantly reduced noise contribution.
The object of the present invention is to provide a kind of high-sound-quality violin without noise, it can thoroughly eliminate the generation high frequency odd harmonic noise factor of not coordinating, and makes its tonequality clean, sensitive, broad, pure and honest, bright, beautiful interesting to listen to.
Its concrete solution is: in above-mentioned existing violin structure under the constant situation of sound column and nightstool distance, the position of sound column is provided with and should makes the distance L 2 and sound column ratio L2/L1 to the distance L 1 of resonant tank inward flange top of sound column to resonant tank inward flange below, sound column is on the distance L 1 and resonant tank of resonant tank inward flange top, the ratio L1/ (L1+L2) of distance L 1+L2 between following inward flange, sound column is to the distance L 4 and the ratio L4/L3 of sound column to the distance L 3 in resonant tank inward flange left side on resonant tank inward flange right side, sound column is to the distance L 3 and a resonant tank left side in resonant tank inward flange left side, the ratio L3/ (L4+L3) of distance L 3+L4 between right inward flange all equates, make that this violin sound column strong point is that the centre of oscillation is on the resonant tank inward flange, down, a left side, conduct vibrations distance L 2/L1=L1/ (the L1+L2)=L4/L3=L3/ (L3+L4) of total length and left and right sides total length is proportional fully about right the reaching, thereby realizes synchronous vibration conduction physically.
In addition then, described sound column is equal to 0.618 than the ratio of the distance L 3 of sound column on the left of the resonant tank inward flange, the sound column distance L 3 on the left of the resonant tank inward flange than the ratio of the distance L 3+L4 between the left and right inward flange of resonant tank to the distance L 4 on resonant tank inward flange right side than the ratio of the distance L 1+L2 between the upper and lower inward flange of resonant tank, sound column than the distance L 1 of sound column to the ratio of the distance L 1 of resonant tank inward flange top, sound column to resonant tank inward flange top to the distance L 2 of resonant tank inward flange below, thus formation golden section proportion structure.
The present invention is owing to adopt to resonant tank inward flange upper and lower, left and right and the up and down structural design of total length, left and right sides total length equal proportion of the sound column strong point, particularly make corresponding ratio be equal to 0.618, adopt best golden section proportion, historical facts or anecdotes has showed proportional vibration and the conduction of the sound column strong point on all directions, reached the effect of sound wave synchronous vibration conduction, thoroughly having removed existing violin disproportionate is nonsynchronous vibration and conduction and cause the do not coordinate factor of high frequency odd harmonic noise of part, has really reached the effect of the high-purity tonequality of noiseless.The lengthening that makes bass area lengthening, treble shortening and string that moves down of sound column is strengthened the vibration of violin in addition, so make that the bass response of violin and high pitch frequency response are all strengthened, the present invention not only tonequality is clean, sensitive, beautiful interesting to listen to, and broad, pure and honest, bright.
