Description

TECHNICAL FIELD

[0001] The utility model relates to an electric piano, especially a novel electric piano key. BACKGROUND

[0002] With the popularization and development of music culture, electric piano as a common musical instrument has been widely welcomed. However, the existing electric piano key has certain defects in design. At present, the pressing end face of most electric piano keys is a horizontal plane, and this design makes the two side edges of the key form a right angle, which is relatively sharp. When performing the playing technique of scratching, the performer will obviously feel the jamming, and the fingers will not slide smoothly on the key, which greatly affects the fluency of performance and the musical expressiveness. At the same time, the sharp key edge is also easy to scratch the fingers, bringing an uncomfortable experience to the performer.

[0003] Although some electric pianos attempt to set a fillet on the two side edges of the key to alleviate the problem of finger scratching, the jamming problem during scratching cannot be effectively solved because the overall pressing end face of the key is still a plane, and the smoothness of performance is still unsatisfactory. Therefore, it is of great practical significance to develop a novel electric piano key that can improve the smoothness of scratching and avoid finger scratching.

[0004] Therefore, it is urgent for the technical personnel in the field to develop a novel electric piano key. CONTENT OF THE UTILITY MODEL

[0005] The utility model is to solve the above-mentioned problems, and provides a novel electric piano key, which solves the problems of scratching jamming and finger scratching of the existing electric piano key, and improves the performance experience of the electric piano through the innovative design of the key pressing surface.

[0006] The above-mentioned purpose of the utility model is realized by the following technical scheme: a novel electric piano key, comprising a key body, wherein an arc-shaped pressing surface is arranged on the upper end face of the key body.

[0007] When the arc-shaped pressing surface is one, the arc-shaped pressing surface covers the entire upper end face of the key body, and the left and right side edges of the arc-shaped pressing surface are filleted. This design makes the key form a smooth arc-shaped surface as a whole, avoiding the problem of sharp edges caused by the traditional flat key. At the same time, the left and right side edges of the arc-shaped pressing surface are filleted, which further optimizes the edge structure of the key, making the fingers more comfortable during contact and sliding, and completely solving the hidden danger of finger scratching. During scratching, the fingers can naturally and smoothly slide along the arc-shaped pressing surface, greatly improving the smoothness of scratching and providing a better performance experience for the performer.

[0008] When there are two curved pressing surfaces, located on the left and right sides of the key body respectively, and a horizontal pressing surface between them, the curved pressing surfaces are tangent to the horizontal pressing surface, and the outer edges of the curved pressing surfaces are rounded. This design combines the characteristics of curved and horizontal surfaces, retaining the familiar feel of the horizontal pressing surface during regular key operation, while using the curved pressing surface to solve the problem of glissando. Furthermore, the tangency of the curved pressing surface to the horizontal pressing surface and the rounded outer edges of the curved pressing surface make the transition of the finger from the curved pressing surface to the horizontal pressing surface or vice versa smoother, without producing obvious abruptness, further improving the smoothness of glissando.

[0009] The advantages of this invention compared to existing technologies are as follows: The novel digital piano keys of this invention effectively solve the problems existing in current digital piano keys through the two innovative design schemes described above. Whether using a single arc-shaped pressing surface covering the entire upper surface of the key body, or a design combining arc-shaped pressing surfaces on both sides with a horizontal pressing surface in the middle, both significantly improve the smoothness of scraping, preventing discomfort to the fingers and thus enhancing the overall playing performance and user experience of the digital piano.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] Example 1: As Figure 1 , Figure 2 As shown, a single arc-shaped pressing surface piano key: a new type of electric piano key, including a key body 1, wherein the upper end surface of the key body 1 is provided with an arc-shaped pressing surface 2, the arc-shaped pressing surface 2 is set as one, the arc-shaped pressing surface 2 covers the entire upper end surface of the key body 1, and the left and right sides of the arc-shaped pressing surface 2 are rounded corners 3.

[0016] In the manufacture of the keyboard of this embodiment, first select the appropriate material, such as high strength, wear-resistant and good texture of engineering plastics, such as polycarbonate (PC) or acrylonitrile-butadiene-styrene copolymer (ABS) and so on. Using high-precision injection mold or CNC machining process, the key body 1 is shaped to ensure that the upper end surface of the key body 1 forms an arc-shaped pressing surface 2 covering the entire surface. In the process of processing, the accuracy of the arc is strictly controlled to ensure the smoothness of the finger sliding on it. At the same time, the left and right sides of the arc-shaped pressing surface 2 are rounded 3, and the transition of the rounded 3 is natural and smooth through polishing and other processes.

[0017] In use, when the performer performs the scratch, the finger contacts the arc-shaped pressing surface 2, and due to its smooth arc-shaped design, the finger can naturally slide along the arc-shaped track, avoiding contact with the sharp edge. Moreover, the entire arc-shaped surface provides continuous support and guidance, making the sliding of the finger more smooth, greatly reducing the feeling of jamming. For example, when playing some pieces that require rapid scratching, the performer can easily and smoothly complete the scratching action, improving the efficiency and quality of the performance.

[0018] Embodiment two: as shown in Figure 3 , Figure 4 The keyboard with two arc-shaped pressing surfaces combined with a horizontal pressing surface in the middle: a new type of electric piano keyboard, comprising a key body 1, the upper end surface of the key body 1 is provided with an arc-shaped pressing surface 2, the arc-shaped pressing surface 2 is two, the two arc-shaped pressing surfaces 2 are respectively located on the left and right sides of the key body 1, and a horizontal pressing surface 4 is provided between the two arc-shaped pressing surfaces 2, the arc-shaped pressing surface 2 is tangent to the horizontal pressing surface 4, and the outer side of the arc-shaped pressing surface 2 is rounded 3.

[0019] Similarly, high-quality engineering plastics are selected as the material of the key body 1, and through precise machining process, arc-shaped pressing surfaces 2 are respectively molded on the left and right sides of the key body 1, and a horizontal pressing surface 4 is formed in the middle part. In the process of processing, it is necessary to ensure that the arc-shaped pressing surface 2 is tangent to the horizontal pressing surface 4 to ensure smooth transition between the two. Accurate machining can be performed using a CNC machine, and professional measuring equipment can be used for detection and adjustment.

[0020] In actual performance, when the performer performs the conventional key operation, the finger is pressed on the horizontal pressing surface 4, and a familiar feeling similar to the traditional key can be obtained. When the scratching is needed, the finger slides from the arc pressing surface 2 on one side, and due to the guiding effect of the arc surface, the finger can smoothly transit to the horizontal pressing surface 4 in the middle and then slide to the arc pressing surface 2 on the other side. In this process, since the arc pressing surface 2 is tangent to the horizontal pressing surface 4, the finger will not feel obvious jerk, and the smoothness of the scratching is significantly improved. For example, when playing some pieces that need to be scratched quickly between different pitches and combined with the conventional key, the design can make the performer more flexible and smooth to complete the performance, and improve the music performance.

[0021] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
