A kind of piano iron strings procession
One, affiliated technical field:
The utility model relates to a kind of Piano Fittings, and particularly a kind of piano iron strings procession accessory belongs to the Piano Fittings technical field.
Two, background technology:
Existing piano exists bass simple and honest inadequately, the middle uneven defective of bass transition, particularly the string of spinet row are arranged unreasonable and science, have influence on its vibration performance, finally influence piano and produce the tonequality of high-quality and the pure acoustical quality of even transition.
Three, summary of the invention
The purpose of this utility model is that the existing piano bass of solution is not simple and honest, the middle uneven defective of bass transition, a kind of spinet science, raisonne iron strings procession are provided, produce scientific and rational vibration performance, make piano produce the tonequality of high-quality and the pure acoustical quality of even transition.
The utility model is achieved by the following technical solution:
The high-quality tonequality of piano is by after rational overspun wire physical dimension and the middle bass reasonable tension transition, produces the sound of high-quality by vibration.Overspun wire is by rationally, after the calculating of science, and certain steel wire string twines the copper wire of certain diameter outward, and has certain force of strain; In bass just can send the uniform high-quality tone color of simple and honest, the middle bass transition of bass after the tension force of even transition is arranged.
Piano iron strings procession of the present utility model, include iron row, peg, capotasto, extension string nail, string, twine silk, its special character is on the peg of string on the iron row, hanging over string by capotasto nails on, be respectively arranged with 33 string groups, 23 string groups, 32 string groups corresponding to piano bass area, middle register and treble, 33 string groups of bass area comprise string group and 20 string groups that two strings constitute that 13 single strings constitute, and 23 middle register string groups and 32 treble string groups are all the string group that three strings constitute; Preceding 8 single strings twine silk inside and outside being tied with bilayer outward in 13 single strings of bass area, and back 5 single strings outside and 20 two strings outsides only are tied with individual layer and twine silk outward, by string with twine and thread constitute overspun wire; The string that outside nothing twines silk is naked string, and 23 middle register string groups and 32 treble string groups are all naked string;
The tone color of piano, tonequality depend on that core string steel wire diameter, the ectonexine of string arrangement mode, string twine the arrangement pitches that twines long and string of effective chord length of the diameter of silk, string, overspun wire etc.;
Each string arrangement pitches has determined the arrangement mode of bass area string group between the 1st string group of bass area, effective chord length of the 33rd string group and the 1st to the 33rd string group; Each string arrangement pitches has determined the arrangement mode of middle register and treble string group between effective chord length of middle register and treble the 34th string group, the 88th string group and the 34th to the 88th string group;
Length between the other string nail in two ends is effective chord length, the length that twines of overspun wire is the length between each 10-20mm place, interval of the other string nail of effective chord length two end distances, the string arrangement pitches is 13.8-14.4mm between the 1st to the 33rd string group, effective chord length of each string is since the 1st string 1178-1206mm 9-15mm to the 13 string 1035-1065mm that successively decrease according to the 1st to the 13rd order between the 1st to the 13rd string group, effective chord length of each string is since the 14th string 1030-1055mm 9-13mm to the 33 string 800-824mm that successively decrease according to the 14th to the 33rd order between the 14th to the 33rd string group, more effective value is that the string arrangement pitches is 14.0-14.2mm between the 1st to the 33rd string group, between the 1st to the 13rd string group effective chord length of each string be according to the 1st to the 13rd order since the 1st string 1185-1200mm 10-14mm to the 13 string 1040-1060mm that successively decrease, effective chord length of each string is since the 14th string 1035-1050mm 10-12mm to the 33 string 805-816mm that successively decrease according to the 14th to the 33rd order between the 14th to the 33rd string group;
The string arrangement pitches is 13.6-14.2mm between middle register the 34th to the 56th string group, the string arrangement pitches is 12.2-12.8mm between treble the 57th to the 88th string group, and effective chord length of each string is since the 34th string 860-890mm 10-20mm to the 88 string 40-60mm that successively decrease according to the 34th to the 88th order between the 34th to the 88th string group; More effective value is that the string arrangement pitches is 13.8-14.0mm between middle register the 34th to the 56th string group, the string arrangement pitches is 12.4-12.6mm between treble the 57th to the 88th string group, and effective chord length of each string is since the 34th string 870-880mm 10-20mm to the 88 string 45-55mm that successively decrease according to the 34th to the 88th order between the 34th to the 88th string group;
The core string steel wire diameter of each string is 1.150-1.225mm between the 1st to the 13rd string group, the core string steel wire diameter of the 14th string group string is 1.150-1.20mm, the core string steel wire diameter of each string is 1.000-1.050mm between the 15th to the 33rd string group, between the 34th to the 88th string group core string steel wire diameter of each string be according to the 34th to the 88th order since the 34th string 1.000-1.050mm every 3-7 string 0.025mm to the 88 string 0.750-0.850mm that successively decrease; More effective value is that the core string steel wire diameter of each string between the 1st to the 13rd string group is 1.175-1.200mm, the core string steel wire diameter of the 14th string group string is 1.175mm, between the 34th to the 88th string group core string steel wire diameter of each string be according to the 34th to the 88th order since the 34th string 1.000-1.050mm every 3-7 string 0.025mm to the 88 string 0.775-0.825mm that successively decrease;
