The beneficial effects of the utility model are that: having carried out design and assembly with action and keyboard, having fixed the part on pattern board and tail piece, the piano true form has been restoreed to this model structure, lets piano temperament teacher assemble, demonstrate through the model, and study piano each position mission profile reaches through exercise on the model and promotes the purpose of maintaining technical ability.

Description

Vertical Steel piano key board teaching model

Technical field

The utility model belongs to musical instrument field, is specifically related to a kind of Vertical Steel piano key board teaching model.

Background technology

Piano is a kind of keyboard instrument in western classicality music, is made up of 88 keys (52 white keys, 36 black keys) and metallic cord soundboard. Piano range scope, from A2 (27.5Hz) to c5 (4186Hz), almost enumerates the whole musical sounds in Musical System. Piano is commonly used to the performances such as solo, ensemble, accompaniment, and composition and rehearsal music are very convenient. The key of executant by pressing on lower keyboard, affects the gavel that enclose suede felt inside piano, then knocks steel wire string and sounds. Piano needs the nursing of timing, ensures that its tone color is constant.

Along with China's economy and culture the improving constantly of level, the consumption of piano is in continuous increase, and it keeps in repair temperament work accordingly and also increases substantially accordingly. Present domestic temperament Shi Baoshou has said 30,000 practitioners, and technical capacity is very different, and a lot of temperament Shi Yin did not accept the training of system, causes them when carrying out after sale service, runs into problem and can not solve at all.

Practical novel content

In order to solve prior art Problems existing, the utility model provides a kind of grand piano keyboard teaching model, and it has simplification piano structure, helps the features such as temperament's teacher study.

The technical scheme that the utility model adopts is:

A kind of Vertical Steel piano key board teaching model, comprise multiple vertical piano striking machine, hammered string instrument described in each comprises that damper always becomes, clutch always becomes, sleeper beam, key and string, also comprise model base plate and support frame, described support frame is surrounded on one end of described model base plate, two supports it are fixed with between described support frame and described model base plate, two described supports are oppositely arranged, being provided with multiple described hammered string instrument between two described supports, the sleeper beam of multiple described hammered string instrument is all fixed on described model base plate. The hammered string instrument of vertical piano and keyboard have been carried out design and assembly by the utility model, parts are fixed on model base plate and tail piece, this model structure reduces piano true form, piano tuning teacher is allowed to be assembled by model, demonstration, study each position technical parameter of piano, can be had the technical ability of oneself by study and promote significantly.

Further, the quantity of described hammered string instrument is 12, and the key of 12 described hammered string instruments comprises 7 white keys and 5 black keys. The utility model, by being simplified by the 88 of piano keys, utilizes 12 hammered string instruments to form a big word group, is also an octave, if can be adjusted by this group 12 key models, so true piano there will not be problem.

Further, described framework comprise one piece before baffle plate and two pieces of side shields, have two string bars between two pieces of described side shields, between two described string bars, be erected with many described strings.

Further, one end of support described in each is fixed on described model base plate, and the other end is fixed on described front baffle plate.

Further, the material that described framework adopts is transparent acrylic board.

The beneficial effects of the utility model are: hammered string instrument and keyboard have been carried out design and assembly, parts are fixed on model base plate and tail piece, this model structure reduces piano true form, piano tuning teacher is allowed to be undertaken by model assembling, demonstrating, study each position technical parameter of piano, reaches, by exercise on model, the object promoting and safeguarding technical ability.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1, model base plate; 2, support frame; 3, string; 4, damper always becomes; 5, clutch always becomes; 6, support; 7, key; 8, sleeper beam; 9, string bar; 10, upper nut; 11, lower bolt.

Embodiment

As shown in Figure 1, the utility model provides a kind of Vertical Steel piano key board teaching model, comprise multiple vertical piano striking machine, hammered string instrument described in each comprises damper and always becomes 4, clutch always becomes 5, sleeper beam, key 7 and string 3, except the basic parts that hammered string instrument comprises, also comprise model base plate 1 and support frame 2, described support frame 2 is surrounded on one end of described model base plate 1, the box body of both composition semi-surroundings, two supports 6 it are fixed with between described support frame 2 and described model base plate 1, two described supports 6 are oppositely arranged, between two described supports 6, multiple described hammered string instrument is installed, the sleeper beam 8 of multiple described hammered string instrument is all fixed on described model base plate 1.

The quantity of the hammered string instrument that the utility model is selected is 12, and the key of 12 hammered string instruments comprises 7 white keys and 5 black keys, to form a big word group, plays unit for one that forms piano, and this is the most easy implementation. Or on the basis of these 12 hammered string instruments, more several hammered string instruments can also be added, become the array configuration of big word group and small character group. The utility model also has multiple change array configuration, does not repeat at this.

Support frame comprise one piece before baffle plate and two pieces of side shields, have two string bars 9 between two pieces of described side shields, string bar is horizontally disposed with, and is erected with many described strings 3 between two described string bars 9, the corresponding hammered string instrument of each string 3. One end of support described in each is fixed on described model base plate 1 by lower bolt 11, and the other end of support is fixed on described front baffle plate by upper bolt and upper nut 10. Pair of brackets carries parts basic on hammered string instrument, as damper always become, clutch always becomes, dynamic back of the body shelves pedestal etc., basically identical with the structure of traditional vertical piano.

As preferably, the material that support frame adopts is transparent acrylic board, therefore, clearly observes linkage and the performance situation of each parts by transparent acrylic board.

The utility model is not limited to above-mentioned preferred forms; anyone can draw the product of other various forms under enlightenment of the present utility model; no matter but in its shape or structure, do any change; every have the technical scheme identical or close with the application, all drops within protection domain of the present utility model.
