Abstract
The invention provides a cast iron plate structure of a piano. The structure comprises a first vertical rib and a second vertical rib which are installed on a piano shell, and a horizontal beam is arranged between the first vertical rib and the second vertical rib; one end of the horizontal beam is bent to be connected with the first vertical rib, the bending angle is 15-20 degrees, and the bending length is 5-8 cm; the other end of the horizontal beam is connected with the end of the second vertical rib, and the connecting end of the horizontal beam is higher than the second vertical rib; fixing blocks are formed on the horizontal beam in an extending mode and provided with fixing holes, and the fixing holes are connected with the piano shell through fixing screws. According to the cast iron plate structure, the piano has the advantages of being clear in tone quality, reasonable in layout and good in timbre effect.
Description
Technical field
The present invention relates to piano technical field, refer 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 up 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 the history of existing more than 300 year, piano range scope is from A2(27.5Hz) to c5(4186Hz), almost enumerate the whole musical sounds in Musical System.It is very convenient that piano is commonly used to the performances such as solo, ensemble, accompaniment, composition and rehearsal music.Player is by by the key on lower keyboard, affecting the gavel that enclose carpet inside piano, then knock steel wire string and send sound.Piano needs the nursing of timing, ensures that its tone color is constant.Two perpendicular ribs of existing piano are independent, adopt independent perpendicular rib easily to loosen, thus affecting piano tonequality and service life.
Summary of the invention
It is an object of the invention 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 present invention is: piano cast iron plate structure, it includes the be arranged on casing of piano first perpendicular rib and the second perpendicular rib, it is provided with crossbeam between first perpendicular rib and the second perpendicular rib, it is connected with the first perpendicular rib after described crossbeam one end bending, its bending angle is 15 ~ 20 °, and bending length is 5 ~ 8cm；The crossbeam other end and the second perpendicular rib end connect, and its link end is perpendicular rib height higher than second, and crossbeam has extended to form 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.
The present invention is after adopting such scheme, crossbeam two ends are fixed by screw and casing of piano, add the stability of piano, tonequality can be made apparent, bending is adopted to be connected between crossbeam with perpendicular rib, making piano layout more reasonable, the factor affecting piano sound being preferably minimized, thus producing the better piano of tonequality.Adopt the advantage that piano has sound clarity, rationally distributed, tamber effect is good after this programme.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with all accompanying drawings, the invention will be further described, presently preferred embodiments of the present invention is: referring to accompanying drawing 1, piano cast iron plate structure described in the present embodiment includes the be arranged on casing of piano 1 first perpendicular rib 2 and the second perpendicular rib 4, it is provided with crossbeam 3 between first perpendicular rib 2 and the second perpendicular rib 4, it is connected with the first perpendicular rib 2 after described crossbeam 3 one end bending, its bending angle is 15 ~ 20 °, and bending length is 5 ~ 8cm；Crossbeam 3 other end and the second perpendicular rib 4 end connect, its link end is perpendicular rib 4 height higher than second, crossbeam 3 has extended to form 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 by screw and casing of piano, add the stability of piano, tonequality can be made apparent, bending is adopted to be connected between crossbeam with perpendicular rib, making piano layout more reasonable, the factor affecting piano sound being preferably minimized, thus producing the better piano of tonequality.
The embodiment of the above is only the preferred embodiments of the invention, not limits the practical range of the present invention with this, therefore all changes made according to the shape of the present invention, principle, all should be encompassed in protection scope of the present invention.
