Abstract

The utility model relates to an improved electronic piano keyboard, belongs to the field of musical instruments, and solves the problem that the tones produced by pressing the black key and the white key with the same note on the current electronic piano keyboard are different, which is unfavorable for playing. The electronic piano keyboard comprises a plurality of black keys, a plurality of white keys and a carbon film mounting board, wherein a plurality of carbon films pressed by the black keys are designed on the carbon film mounting board corresponding to the pressing positions of the black keys, and the carbon film pressed by the black key is 30 mm in length and 3.9 to 4.1 mm in width; and a plurality of carbon films pressed by the white keys are designed on the carbon film mounting board corresponding to the pressing positions of the white keys, and the carbon film pressed by the white key is 30 mm in length and 1.9 to 2.1 mm in width. In the electronic piano keyboard, as the sizes of carbon films pressed by the white keys are reduced, a very natural tone can be achieved by a player during the playing process without the necessity of differentiating the black and the white keys.

Description

A kind of improved piano key board

Technical field

The utility model relates to the musical instrument field, particularly relates to a kind of improved piano key board.

Background technology

Referring to Fig. 1 and Fig. 2, the piano key board of prior art, comprise a plurality of black keys 1, a plurality of white key 2 and a carbon film installing plate 3, corresponding with the position that black key 1 is pushed, the carbon film plate 5 that design has that multi-disc is subjected to that black key pushes on carbon film installing plate 3, be subjected to that black key pushes carbon film plate 5 long 30mm, wide 3.9mm～4.1mm; The carbon film plate 4 corresponding with the position that white key 2 is pushed, that design has that multi-disc is subjected to that Bai Jian pushes on carbon film installing plate 3, be subjected to that Bai Jian pushes carbon film plate 4 long 30mm, wide 3.9mm～4.1mm.That is: be subjected to that black key pushes carbon film plate 5 be subjected to that Bai Jian pushes carbon film plate 4 measure-alike, black key 1 is identical with the contact area of its corresponding carbon film plate of pushing with Bai Jian 2, because like this, the player is in actual playing procedure, the tonequality of pressing the black key 1 of same note and Bai Jian 2 and producing is differentiated, and this just brings disadvantageous effect to performance.In order to make the player in playing procedure, need not to realize white black key dish, both can obtain the playing effect of very natural tone color, people wish that urgently a kind of improved piano key board comes out.

The utility model content

Technical problem to be solved in the utility model is, the piano key board that overcomes prior art is at the black key of pressing same note and Bai Jian and the tonequality that produces is defective differentiated, bring unfavorable effect to performance, satisfy people's the eager desire and the market demand of piano key board, a kind of improved piano key board is provided, it is identical that this improved piano key board is pressed the tonequality that the black key of same note produces with Bai Jian, make the player in playing procedure, need not to realize white black key dish, both can obtain the playing effect of very natural tone color.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of improved piano key board, comprise a plurality of black keys, a plurality of white key and a carbon film installing plate, corresponding with the position that black key is pushed, the carbon film plate that design has that multi-disc is subjected to that black key pushes on the carbon film installing plate, be subjected to that black key pushes carbon film length of a film 30mm, wide 3.9mm～4.1mm; The carbon film plate corresponding with the position that white key is pushed, that design has that multi-disc is subjected to that Bai Jian pushes on the carbon film installing plate, be subjected to that Bai Jian pushes carbon film length of a film 30mm, this improved piano key board be subjected to that Bai Jian pushes the wide 1.9mm～2.1mm of carbon film plate.

The beneficial effects of the utility model are: a kind of improved piano key board of said structure, since be subjected to that Bai Jian pushes its size of carbon film plate change little, make the contact area of the corresponding carbon film plate of pushing of white key diminish with it, it is identical causing pressing the tonequality that the black key of same note produces with Bai Jian, thereby make the player in playing procedure, need not to realize white black key dish, both can obtain the playing effect of very natural tone color.Solve problem to be solved in the utility model, reached the purpose of this utility model.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is the inner structure synoptic diagram of the utility model before improvement;

Fig. 3 is the inner structure synoptic diagram of the utility model after improvement.

Among the figure, 1, black key; 2, Bai Jian; 3, carbon film installing plate; 4, be subjected to that Bai Jian pushes carbon film plate; 5, be subjected to that black key pushes carbon film plate.

Embodiment

Referring to Fig. 1 and Fig. 3, the described a kind of improved piano key board of present embodiment, comprise a plurality of black keys 1, a plurality of white key 2 and a carbon film installing plate 3, corresponding with the position that black key 1 is pushed, the carbon film plate 5 that design has that multi-disc is subjected to that black key pushes on carbon film installing plate 3, be subjected to that black key pushes carbon film plate 5 long 30mm, wide 4mm; The carbon film plate 4 corresponding with the position that white key 2 is pushed, that design has that multi-disc is subjected to that Bai Jian pushes on carbon film installing plate 3, be subjected to that Bai Jian pushes carbon film plate 4 long 30mm, wide 2mm.Since be subjected to that Bai Jian pushes carbon film plate 4 its sizes change little, make the contact area of the corresponding carbon film plate of pushing of white key 2 diminish with it, the black key 1 that causes pressing same note is with Bai Jian 2 and the tonequality that produces is identical, thereby make the player in playing procedure, need not to realize white black key dish, both can obtain the playing effect of very natural tone color.Solve problem to be solved in the utility model, reached the purpose of this utility model.

The above only is a preferred embodiment of the present utility model; be not to be used for limiting the utility model, all its similar embodiment and approximate structure, for example; be subjected to that Bai Jian pushes the wide 1.9mm～2.1mm of carbon film plate etc., these features all should be covered by the protection domain of the utility model patent.
