Abstract
The invention discloses a piano key which comprises a key body, a key cover and a non-traditional material sheet or film, wherein the non-traditional material sheet or film is bonded to the upper surface of the key body with an adhesive; the length of the non-traditional material sheet or film can penetrate through the whole piano key; the non-traditional material sheet or film can be used in one section or multiple sections; and other parts, such as, a white key cover, a black key cover, and the like, are arranged on the non-traditional material sheet or film. The invention provides the piano key which is characterized by taking the non-traditional material including carbon fiber and supplementing with the reasonable design of a piano key structure, so that the purposes of increasing key strength and stiffness, preventing key cracking, effectively restraining the key deformation and cracking and increasing the mechanical property of the piano key are achieved.
Description
Technical field
The present invention relates to a kind of piano key, belong to piano key field.
Background technology
Key is the parts that player's piano contacts at first, and its effect is to piano the Movement transmit of player's finger.The mechanical property of key self, comprise moment of inertia, intensity, rigidity, section modulus etc., " sense of touch " of capital to piano has an impact (piano tactility refers to the weight of player's finger contact key, and the sensation such as to releive is one of important indicator of piano performance performance).
300 for many years, and piano key adopts wooden material manufacture always, also has indivedual tentative research adopting synthetic material to manufacture key.The problems such as due to the natural characteristic of timber, wooden keys existence comprises cracking, the stability (be also called the weatherability of timber, referring to timber can occur interim bending along with the change of environment, the distortion such as torsion) of permanent strain and wood quality.For huge event meeting trigon, the bending stiffness of wooden keys is on the low side is the principal element restricting piano volume and sound propagation performance.
With the large-scale playing piano that nine Foot platform qins are representative, its key is longer than the baby grand key of exercise, and in playing procedure, the flexural deformation of long key is also larger.Experiment shows, when great dynamics plays certain product Chinese dominoes Foot piano bass, near player one end, almost touching the packing ring above front, (packing ring is used for limiting key front end to be continued to decline key, to ensure that key gets out repetition motion next time) time, the little Chui (sounding for beaing string) of the hammered string instrument other end just starts to occur obvious motion.Little Chui startup hysteresis not only affects the sense of touch of key in player's finger movement, also show quite a few energy playing key and be consumed in key bending deformation process.Because key insufficient rigidity causes little Chui motion seriously delayed, more powerful player can not perform to ultimate attainment the volume of piano, and music hall acoustic radiating effect is affected naturally.
As a kind of natural material, timber has annual ring, density, the natural characteristics such as knot and defect.Wooden keys is more responsive to ambient temperature and humidity, and can occur distortion along with the change of ambient humidity, namely wooden parts exists performance instability.In order to avoid the various problems that timber natural characteristic causes, piano fabricator except taking measures in selection and treating of wood, have also appeared the method that multilayer board manufactures key in recent years, namely adopt three layers or multilayer wooden material, wood grain is according to the interlaced manufacture key of certain design rule.What the manufacturing technology of this sandwich construction effectively limit that timber natural defect causes comprises some problems such as distortion and cracking.But Multilayer Material a large amount of tackifier used in manufacturing process increases density and the weight of key self unavoidably.From reality, current multilayer board is mainly used in key manufacture that is universal and exercise qin, and high-grade piano rarely has the example using composite wood board material to make key.
Summary of the invention
The invention provides a kind of piano key, by using the non-traditional materials comprising carbon fiber, being aided with the appropriate design of key structure, reach and improve key strength and stiffness, prevent key from ftractureing, effectively suppress key distortion, improve the objects such as key mechanical property.
The present invention is achieved by the following technical solutions:
A kind of piano key, comprises key body, key skin, is bonded with thin plate or film at the upper surface of key body.
The lower surface of described key body is bonded with thin plate or film.
Described thin plate or the length of film or run through whole key or only use or some sections of uses at middle one section.
Enhancement Layer is provided with bottom described key body.
Described enhancement Layer width and key are with wide or slightly narrower than key.
Described enhancement Layer and key body one also can be bonded in it key.
Described thin plate or film be by carbon fiber and adopt carbon fiber-reinforced synthetic material, basalt fibre and adopt basalt fibre strengthen material, glass fibre and adopt glass fiber-reinforced material, aramid fiber and adopt aramid fiber strengthen material in one or more make.
Described enhancement Layer be by timber, plastics, carbon fiber and adopt carbon fiber-reinforced synthetic material, basalt fibre and adopt basalt fibre strengthen material, glass fibre and adopt glass fiber-reinforced material, aramid fiber and adopt aramid fiber strengthen material in one or more make.
A kind of piano key, comprise key body and key skin, described key body adopt carbon fiber and adopt carbon fiber-reinforced synthetic material, basalt fibre and adopt the material of basalt fibre strengthening, glass fibre and adopt glass fiber-reinforced material, aramid fiber and adopt in the material of aramid fiber strengthening one or more make, the xsect of key front end namely near player one end adopts " work " word-lifting formula.
Compared with prior art, beneficial effect of the present invention is: with regard to the intensity of material, and the rift grain fracture strength of timber is generally in 0.07GPa to 0.12GPa scope, and the fracture strength of carbon fiber can reach more than 3.5GPa, and both differ tens times.With regard to affecting the elastic modulus of key bending stiffness, the Young's modulus of elasticity of timber rift grain is generally between 9GPa to 12GPa, and the Young's modulus of elasticity of carbon fibre material can reach more than 200GPa.Traditional wooden material is compared with the non-traditional materials taking carbon fibre material as representative, and mechanical property difference is huge; The density of carbon fibre material is little, and material is light.Effectively utilize this kind of non-traditional materials effectively can also control the weight of key self while promoting key mechanical property, thus ensure that key lightweight is flexible.
