Abstract
一种钢琴复合音板，涉及一种钢琴部件，该复合音板的芯板采用径切云杉或径切冷杉板条拼接而成；芯板上的表板由碳纤维板制成，表板上设置有若干中空的孔洞；芯板下的背板由碳纤维板制成。本实用新型解决了现有技术选材苛刻和振动不均匀的问题，提高了钢琴音板的耐候性。
A composite soundboard for a piano, which relates to a piano part. The core board of the composite soundboard is spliced by quarter-cut spruce or fir slats; Several hollow holes are arranged; the back plate under the core plate is made of carbon fiber plate. The utility model solves the problems of harsh material selection and uneven vibration in the prior art, and improves the weather resistance of the piano sound board.
Description
Technical field
The utility model relates to a kind of piano parts, is specifically related to a kind of piano soundboard.
Background technology
The traditional fabrication of piano soundboard is to adopt the splicing of Pinaceae Picea plank of solid wood, forms through fixed thick sanding again, and this piano soundboard is selected materials and required harshly, and any natural defect can not be arranged, and grain of wood aberration etc. is all had strict restriction; This in addition solid wood soundboard weatherability is poor, and after moisture absorption or drying out, yielding or cracking has had a strong impact on the piano quality; This solid wood soundboard quality is loose, and texture is thicker, though be easy to vibration sounding, vibrates evenly inadequately, thereby can cause the deficiency that piano voice is more coarse, tone color is mellow and full inadequately.
Chinese patent ZL94216601.9 provides a kind of piano Complex soundboard; This patent Complex soundboard by dash board, central layer, backboard is compound forms, middle central layer selection is less demanding, though this patent has solved the harsh problem of piano soundboard selection to a certain extent; But because dash board, central layer and backboard all adopt solid wood; So weatherability is still bad, in case moisture absorption or dry out after, yielding or the cracking; The vibration of this patent soundboard simultaneously is still inhomogeneous, and piano sound is bad.
The utility model content
The purpose of the utility model provides a kind of piano Complex soundboard, solves prior art selection harshness, weatherability difference and vibrates uneven problem.
The utility model mainly is made up of central layer, dash board and backboard, and solving the technical scheme that its technical problem adopts is that central layer adopts quarter sawing dragon spruce or quarter sawing fir lath to be spliced; Dash board on the central layer is processed by carbon fiber board, and dash board is provided with the hole of some hollows; Backboard under the central layer is processed by carbon fiber board.
The above-mentioned dash board and the thickness of backboard are 1-4mm.
Hole on the above-mentioned dash board can be rectangle or circle.
The beneficial effect of the utility model is:
1, carbon fiber board have lightweight, indeformable, do not ftracture, non-hygroscopic, antifatigue, advantage that weatherability is high, dash board and backboard adopt carbon fiber board to process, the solid wood central layer in the middle of can protecting improves the weatherability of whole piano soundboard; Through using carbon fiber board, the carbon fiber version is easy to machine-shaping, has not only reduced the use amount of solid wood board, has also reduced the selection requirement of piano soundboard to a certain extent simultaneously.
2, dash board is a hollow structure, and the hole on the dash board has played the effect of division unit to soundboard, thereby it is more even that the soundboard vibration is taken place, and has improved the tone color of piano.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1 central layer, 2 dash boards, 3 backboards, 4 holes among the figure.
The specific embodiment
As shown in the figure, a kind of piano Complex soundboard mainly is made up of central layer 1, dash board 2 and backboard 3, and central layer 1 adopts quarter sawing dragon spruce lath to be spliced; Dash board 2 on the central layer 1 is processed by the 2mm carbon fiber board, and the hole 4 of some hollows is set on the dash board 2, and the hole 4 on the dash board 2 is a rectangle; Backboard 3 under the central layer 1 is processed by the 2mm carbon fiber board.
Claims (3)
1. a piano Complex soundboard mainly is made up of central layer, dash board and backboard, it is characterized in that central layer adopts quarter sawing dragon spruce or quarter sawing fir lath to be spliced; Dash board on the central layer is processed by carbon fiber board, and dash board is provided with the hole of some hollows; Backboard under the central layer is processed by carbon fiber board.
2. piano Complex soundboard according to claim 1, the thickness that it is characterized in that dash board and backboard is 1-4mm.
3. piano Complex soundboard according to claim 1 is characterized in that the hole on the dash board can be rectangle or circle.
