Description

A kind of piano

Technical field

The invention belongs to musical instrument technical field, more particularly, to a kind of piano.

Background technology

Piano is a kind of keyboard instrument in western classical music, the laudatory title for having " king of musical instrument ".By 88 keys and gold Category string soundboard composition.Piano range scope enumerates the whole musical sounds in Musical System from A227.5Hz to c54186Hz, almost, It is the most wide musical instrument of range in addition to pipe organ.Piano is commonly used to the performance such as solo, ensemble, accompaniment, composition and rehearsal sound Pleasure is very convenient.Player then taps steel by by the key on lower keyboard, affecting piano the inside to enclose the gavel of carpet Silk string sends sound.In Piano Teaching, beginner is often unfamiliar with so much key, is very easy to push the wrong, without one Plant the piano that can aid in guiding beginner correctly to press opposite position key successively according to music score.

In order to be improved to prior art, people have carried out long-term exploration, it is proposed that various solutions. For example, Chinese patent literature discloses a kind of piano for teaching [CN201410314681.9], including piano body and key Area, is also equipped with a fingerprint recognition and opens dress on the piano body；The key area includes the first key area and with first Second key area of key area relative position, is equipped with transformation region, second qin on each key in the second key area Exercise logging modle, discoloration instruction module and fraction assessment module, the exercise logging modle and the are respectively equipped with keypad One key area, the second key area form electrical connection；The exercise logging modle and discoloration instruction module, transformation region are formed electrically Connect and the exercise logging modle and discoloration instruction module, fraction assessment module and the second key area form and electrically connect Connect.

Although such scheme solves the deficiencies in the prior art to a certain extent, can not aid in guiding beginner It is correct successively to press key.

The content of the invention

Regarding the issue above, the present invention provides a kind of reasonable in design, the piano that beginner can be aided in learn.

To reach above-mentioned purpose, present invention employs following technical proposal：This piano includes mid-game, described mid-game it is upper Portion is equipped with periphery, and the bottom of mid-game is provided with some qin pin, and iron row, described mid-game are provided with the inner chamber that described periphery surrounds The key of peripherally located open-mouth is provided with, described key is connected by hammered string instrument with mallet, is also set in described mid-game There is the string positioned at mallet sidepiece, and mallet taps corresponding string sounding when key is depressed, described outer placing sets There is top cover, described top cover is propped up by support frame, middle pin is additionally provided with described mid-game, being provided with a left side between described middle pin steps on Pin, middle step and right step, described pedal are connected by pedal push rod with hammered string instrument, and described peripheral open-mouth also cuts with scissors The rolling cover that can be covered on key is connected to, the music stand for being additionally provided with and being placed for qin spectrum is placed outward, it is characterised in that described key Including the key body with hollow cavity, the first illuminator is provided with described key body, the first described illuminator leads to Cross electric wire to be connected with controller, described controller is arranged on rolling cover, and controller is just right when rolling cover has been turned upward Piano user.The first illuminator in controller control key is sequentially lighted according to music score, and beginner can follow the first hair The order that body of light is lighted presses key successively, so as to guide beginner to press key successively according to music score, improves of beginner Practise efficiency, the position of key is familiar with beneficial to beginner, this be pattern one because the speed that the first illuminator is lighted be set and Comparatively fast, so suitable for there is certain basic beginner.

In above-mentioned piano, the upper end of described key body is open, and open section is coated with key keypad, described Key keypad be detachably connected with key body, the second illuminator, adjacent key body are provided with described key body Between be provided with the switch module that the second illuminator can be controlled to light, the second described illuminator is connected with controller.Pressing The key pressed required for first, the first contact and the second wafer are in contact, circuit turn-on, and controller controls institute according to music score The second illuminator in next key that needs are pressed is lighted, so as to instruct the position where the next key of beginner, just The order that scholar only needs to be lighted according to the second illuminator is pressed successively, and this is pattern two, and the pattern is entirely according to just The speed of scholar oneself pressing key is indicated, it is adaptable to the weaker beginner in basis.

In above-mentioned piano, described switch module includes the first contact and the second wafer, and the first described contact sets Put on the key of side this body sidewall, the second wafer is arranged on the key of opposite side this body sidewall, and when key body quilt The first contact and the second wafer are in contact so that the illuminator of circuit turn-on second is lighted when pressing.First contact and the second wafer phase Contact, the circuit turn-on connected with controller, controller is lighted so as to control the second illuminator.

In above-mentioned piano, the first described contact and the second wafer are horizontally disposed with, and the first described contact is located at The top of the second wafer, and the first contact is fixedly connected with the key body of side, the key body of the second wafer and opposite side Elastic Sliding is connected.Elastic Sliding connection has certain cushioning effect, that is, avoid the first contact and the second wafer hardness connects Touch, also avoid loose contact problem caused by the loosening because of the first contact and the second wafer.

In above-mentioned piano, slide-and-guide block, the key body of opposite side are fixedly connected with described the second wafer On be provided with the slide-and-guide groove being engaged with slide-and-guide block, slide-and-guide block is described along slide-and-guide groove longitudinal sliding motion It is provided with buffer spring between slide-and-guide block and slide-and-guide groove, described buffer spring has upward pre- to slide-and-guide block Clamp force.

In above-mentioned piano, the first mounting seat for being installed for the first illuminator is provided with described key body and the is supplied The second mounting seat that two illuminators are installed, lamp body mounting groove and electricity are offered in the first described mounting seat and the second mounting seat Line passes groove, and described lamp body mounting groove passes groove and is connected with electric wire.Installed by the first mounting seat and the second mounting seat, profit In stabilized structure.
