Abstract

The utility model discloses a piano sounding board, which mainly comprises board sheets of an upper layer, a middle layer and a lower layer, wherein, the upper layer and the lower layer is the veneer overlay made of red pine and white pine, and the thicknesses are 0.6-0.8 mm. The middle layer is the splicing board made of the paulownia, and the thickness is 4-10 mm. An adhesive layer is between the adjacent layers, and the textures of the warp direction or the chord direction of the veneer overlay made of the red pine and the white pine and the splicing board made of the paulownia form an included angle of 35-37DEG. The sounding board has simple structure. The paulownia board keeps the structure of the paulownia self, and thus, the fibrous structure, conduit, wood body lines and sound speeds of the longitudinal direction and the radial chord direction of the paulownia don't generate any change. As a consequence, the sound volume and the sound rhythm of the piano are more perfect; the cost of the sounding board is reduced.

Description

The piano pronunciation board
The utility model relates to a kind of musical instrument pronunciation board, relates in particular to a kind of piano pronunciation board.
Traditional piano pronunciation board adopts kahikatea or Korean pine to make, the pronunciation board of this structure is strict to timber, thereby cost height, and voice effect is also undesirable, at present, along with science and technology development, improvement people to the paulownia wood treatment process utilize paulownia making musical instrument pronunciation board to become development trend, someone has designed a kind of musical instrument pronunciation board, this plate is to utilize paulownia and red kahikatea rotary-cut plate to form the pronunciation board with sandwich construction, the pronunciation board of this structure is though its voice effect is better, owing to adopt the thin paulownia plate of rotary-cut, cause the degree of tightness facial cleft line in the paulownia rotary-cut in process of production easily, the fibre guide structure that makes paulownia of breaking when dry is damaged, and gap in the assembly, lamination, mend the cavity, gap by replacing a damaged part, pronunciation resonance is all had a significant impact, destroyed the self structure of paulownia, the pronunciation resonance effect of paulownia is changed, can not really embody paulownia in pronunciation, the advantage of aspects such as resonance.
The purpose of this utility model provide a kind of simple in structure, cheap, can keep the paulownia self structure, and can make full use of the advantage of paulownia aspect pronunciation board, improve the piano pronunciation board of the voice effect of pronunciation board.
The technical solution of the utility model realizes in the following manner:
A kind of piano pronunciation board, it mainly comprises upper, middle and lower-ranking sheet material, its upper and lower two-layer be red, kahikatea veneer overlay, thickness is 0.6-0.8mm, the middle layer is the paulownia jigsaw, thickness is 4-10mm, is adhesive phase between the adjacent layer, red, kahikatea veneer overlay and paulownia jigsaw radially or tangential texture form 35-37 ° of angle.
Red kahikatea veneer overlay and paulownia jigsaw radially or the angle of tangential texture be preferably 36 °.
Good effect of the present utility model is;
1, simple in structure; whole soundboard has only three layers of composition except that adhesive phase; middle paulownia plate is an integral body; protected the self structure of paulownia; make the fibre structure, conduit, wooden body line of paulownia and vertically, any variation do not take place in the radially tangential velocity of sound; given full play to paulownia in the advantage of making the piano pronunciation board, made volume, the musical note perfection more of piano.
2, save resource, 1/10 the middle layer that this pronunciation board is the thickest accounts for whole plate is the paulownia flaggies, thereby has saved more valuable red, kahikatea wood plank greatly, and the cost of pronunciation board is reduced greatly.
3, this piano pronunciation board steady quality, easily commodity inspection utilizes the living paulownia resource of the exclusive speed of China to produce the piano pronunciation board and has vast market prospect.
The utility model is described in further detail below in conjunction with accompanying drawing:
By accompanying drawing as can be seen, this piano pronunciation board upper strata 1, lower floor 8 is respectively red, kahikatea quarter sawing veneer, its thickness is 0.7mm, the middle layer is that thickness is the paulownia jigsaw 6 that 8mm is spliced by radially texture jigsaw 4 and tangential texture jigsaw 5 respectively, red, white quarter sawing veneer (1,8) adopt and between the paulownia jigsaw 6 plasticity strong, anti-aging, moisture proof, the modified urea-formaldehyde resin that bond strength is high sticks to one it with the adhesive layer 2 that polyvinyl acetate emulsion mixes mutually, on, following two-layer (1,8) red, kahikatea veneer and paulownia are radially, angle between the tangential texture jigsaw is 36 °, on, following two-layer (1,8) red, the piece of kahikatea veneer is bonding with thermoplastic resin 7.

Claims (2)
