Abstract
The utility model relates to a composite piano sound board which comprises an upper panel and a lower panel, wherein the edges of the upper panel and the lower panel are connected through a plurality of support rods; an air layer capable of improving the vibration performance of the piano sound board is formed between the upper panel and the lower panel; the upper and lower panels are composite boards; the upper panel comprises upper metal net cloth, upper carbon fiber cloth and an upper wood core board which are glued in sequence; the lower panel comprises a lower wood core board, lower carbon fiber cloth and lower metal net cloth which are glued in sequence; a plurality of support rods are uniformly distributed between the edges of the upper wood core board and the lower wood core board. According to the composite piano sound board, the vibration performance and the energy transmission performance are better, the lasting time of sound due to string vibration is long, and a piano can generate a more beautiful sound and achieve a pure sound quality effect. Therefore, the composite piano sound board has higher practical application and promotion values.
Description
Technical field
The utility model relates to a kind of musical instrument soundboard, particularly a kind of compound piano soundboard.
Background technology
Existing piano soundboard mostly is wooden sound board, and this wooden sound board cost is higher, and stricter to material requirement, selection is more difficult, and wooden sound board is after moisture absorption or drying out, and is easily out of shape or cracking; In addition, also there is a kind of Complex soundboard, formed by the panel being glued together in turn, central layer and composition of backboards, but, the vibration performance of this Complex soundboard and energy transmit poor-performing, and the vibratory sound of string is impermanent, and the sound equipment that piano produces and acoustical quality are not very desirable.
Summary of the invention
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, and a kind of compound piano soundboard is provided.The vibration performance of this compound piano soundboard and energy transmission performance are higher, and the vibratory sound of string is permanent, make piano produce more graceful sound equipment and pure acoustical quality.
For solving the problems of the technologies described above, this compound piano soundboard, comprise top panel and lower panel, between described top panel and the edge of described lower panel, connect by several support bars, between described top panel and lower panel, form the air layer that can improve piano soundboard vibration performance; Described top panel is composite plate.
So design, by upper and lower panel is separated, and is connected to form air layer by support bar, and in addition, top panel adopts after composite plate design, and it is higher that the vibration performance of soundboard and energy transmit performance; The vibratory sound of string is permanent, makes piano produce more graceful sound equipment and pure acoustical quality.
As optimization, described lower panel is composite plate.
As optimization, described top panel comprises the upper metal screen cloth, upper carbon cloth and the upper block board that glued joint in turn.So design, vibration performance and acoustical quality are all improved.
As optimization, described lower panel comprises the lower block board, lower carbon cloth and the lower metal screen cloth that glued joint in turn.So design, vibration performance and acoustical quality are further enhanced.
As optimization, between described upper central layer and described lower block board edge, be evenly equipped with several support bars.
As optimization, described upper block board and described lower block board are rectangular parallelepiped, and are evenly equipped with respectively 3 support bars between 4 opposite edges of described upper block board and described lower block board.So design, design science is reasonable, and firmly.
As optimization, the tinsel of described upper metal screen cloth and lower metal screen cloth is all woven and is formed by twill mode, and diameter wiry is 0.005-0.020mm, and mesh diameter is 0.025-0.03mm.So design, result of use is better.
As optimization, described upper carbon cloth and lower carbon cloth are twill.So design, result of use is better.
As optimization, the thickness of described upper metal screen cloth, upper carbon cloth and upper block board is all greater than the thickness of described lower metal screen cloth, lower block board and lower carbon cloth.So design, design science, rationally and result of use better.
The compound piano soundboard of the utility model, vibration performance and energy transmission performance are higher, and the vibratory sound of string is permanent, makes piano produce more graceful sound equipment and pure acoustical quality.There is good actual application value and promotional value.
