Abstract
The utility model provides a piano cast iron plate structure, it is including installing first perpendicular rib and the perpendicular rib of second on the piano shell, and first perpendicular rib and second erect and are equipped with the crossbeam between the rib, crossbeam one end bend the back be connected with first perpendicular rib, its angle of bending is 15~20, the length of bending is 5~8cm, the crossbeam other end erects rib end connection with the second, and its link tip is higher than the second and erects the rib height, extends on the crossbeam to be formed with the fixed block, is equipped with the fixed orifices on the fixed block, and the fixed orifices passes through set screw and is connected with the piano shell. Piano after this scheme of adoption has the advantage that tone quality is clear, rationally distributed, the tone quality is effectual.
Description
Technical field
This utility model relates to piano technical field, refers in particular to piano cast iron plate structure.
Background technology
Piano is a kind of keyboard instrument in western classicality music, pulls hammer to beat string with key.Since 18 end of the centurys, in Europe and the U.S., piano is always topmost family keyboard instrument.Europe risen in by piano, 18 beginnings of the century, the keyboard musical instrument of a kind of similar modern piano of Italian's Christopher's profit invention.So far having the history of more than 300 year, piano range scope is from A2(27.5Hz) to c5(4186Hz), almost enumerate the whole musical sounds in Musical System.Piano be commonly used to solo, play again, the performance such as accompaniment, music of wrirting music and rehearse is very convenient.Player, by by the key on lower keyboard, affects the gavel that enclose carpet inside piano, then taps steel wire string and sends sound.Piano needs the nursing of timing, ensures that its tone color is constant.Two perpendicular ribs of existing piano are independent, use independent perpendicular rib easily to loosen, thus affect piano tonequality and service life.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of sound clarity, the piano cast iron plate structure that rationally distributed, tamber effect is good.
For achieving the above object, technical scheme provided by the utility model is: piano cast iron plate structure, it includes first be arranged on casing of piano and erects rib and second and erect rib, first erects rib and second erects and is provided with crossbeam between rib, erect rib with first after described crossbeam one end bending to be connected, its bending angle is 15 ~ 20 °, a length of 5 ~ 8cm of bending；The crossbeam other end and second erects rib end and connects, and it connects end end and erects rib height higher than second, crossbeam extends and is formed with fixed block, and fixed block is provided with fixing hole, and fixing hole is connected with casing of piano by fixing screw.
Described fixed block is two, lays respectively at crossbeam two ends.
This utility model is after using such scheme, crossbeam two ends are fixed with casing of piano by screw, add the stability of piano, tonequality can be made apparent, bending is used to be connected between crossbeam with perpendicular rib, make piano layout more reasonable, the factor affecting piano sound is preferably minimized, thus produces the more preferable piano of tonequality.Use the advantage that piano has sound clarity, rationally distributed, tamber effect is good after this programme.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with all accompanying drawings, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1, piano cast iron plate structure described in the present embodiment includes first be arranged on casing of piano 1 and erects rib 2 and second and erect rib 4, first erects rib 2 and second erects and is provided with crossbeam 3 between rib 4, erect rib 2 with first after described crossbeam 3 one end bending to be connected, its bending angle is 15 ~ 20 °, a length of 5 ~ 8cm of bending；Crossbeam 3 other end and second erects rib 4 end and connects, it connects end end and erects rib 4 height higher than second, extend on crossbeam 3 and be formed with fixed block 5, described fixed block 5 is two, lay respectively at crossbeam 3 two ends, fixed block 5 is provided with fixing hole 6, and fixing hole 6 is connected with casing of piano 1 by fixing screw 7.The crossbeam two ends of the present embodiment are fixed with casing of piano by screw, add the stability of piano, and tonequality can be made apparent, bending is used to be connected between crossbeam with perpendicular rib, make piano layout more reasonable, the factor affecting piano sound is preferably minimized, thus produces the more preferable piano of tonequality.
The embodiment of the above is only the preferred embodiment of this utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to this utility model, principle are made, all should contain in protection domain of the present utility model.
