Abstract

The invention relates to a musical instrument production, which uses computer, micro electric and computer network to realize system control and electric-control string hammering, wherein based on present voice of piano, it uses electric-control string hammering to replace the former lever activation; the castanet and string-expand machine are flexibly arranged, to select the string code position and the string hammer point; the shape can be designed freely; and each function element is independent, to support batch production.

Description

technical field [0001] The invention belongs to the technical field of musical instrument manufacturing, and specifically relates to a piano with a new structure, in particular to the transformation of the traditional piano structure and the transformation of the manufacturing industry by using modern high-tech means. Background technique [0002] The piano belongs to the "percussion instrument" in the taxonomy of musical instruments. The reason why it is called the king of musical instruments is not only because of its huge size, but also because of its very complicated structure; the piano is composed of tens of thousands of parts. As the heart of the piano, the action has more than 5,000 parts. The keyboard and the action form an integrated keyboard mechanical system, which can transmit the percussion force when the key is struck to the human body through the key bar. In the action, the linkage lever in the action causes the hammer to actuate the string to produce sound. ...

Problems solved by technology

[0008] 4. String tensioning system - the sounding body of the piano, which is composed of wooden brackets, iron brackets, soundboards, strings, pegboards, tuning nails, string nails, string codes and other components; after the strings are struck by the hammer Vibration is generated, and the vibration wave is transmitted to the soundboard by the string code and the other string nails, and resonates through the resonance of the soundboard to produce a loud sound; the length, thickness, and tension of the string group (string column) determine the vibration basis of the sound. The production of high-frequency and overtones, the setting of accurate and reasonable striking points is an important guarantee for excellent acoustic quality. Although there are ingenious designs for the selection of striking points in modern piano systems, there are still many problems in the implementation of the goals. Inadequacies; the string system is independent of other systems in the overall structure of modern pianos, and has its own acoustic design method, which is the root of people's favorite piano (piano timbre)

[0010] Due to the shackles of the rigid keyboard mechanical system, it is difficult for modern pianos to further improve and improve both in terms of the improvement of acoustic quality and the flexibility of manipulation and performance, so that artists are pursuing higher levels. The artistic expression of the piano makers, the constant requests made to the piano makers, and the various efforts made by the piano makers to design and make better pianos have become futile.

[0011] In addition, due to the wide and unscrupulous manufacturing standards of the parts in modern pianos, the assembly and debugging process is lagging behind. It is difficult to achieve unity and consistency, and it still belongs to the manual manufacturing mode

Steinway pianos are world-class, and the main reasons why they can become the best brand pianos in the world: one is to choose high-quality wood as the material for making parts; the other is that they have many experienced craftsmen Although modern processing machinery and processing technology are used in the production and processing process, in many woodworking production and assembly debugging links, it is still necessary to rely on experienced craftsmen to complete the production by hand.

[0012] Also, in the structure of piano parts, except for a few metal materials such as cast iron bones, strings, shaft nails and screws, most of the parts are made of wood materials, among which fish scale spruce is also called white pine. , used to make soundboards, ribs, keys, keyboard frames, etc.; maple, also known as colored wood, is used to make action parts, piano codes, etc., which consumes a lot of natural resources and is not conducive to environmental protection

[0013] Various reasons indicate that because modern pianos have been using the traditional integrated keyboard action lever structure, resulting in poor consistency of product performance and inconsistent product quality in modern piano manufacturing, backward assembly and debugging technology, manual-based, and technological content in products. low backwardness
