[0002] The thumb piano (or "kalimba", English name: Carlimba) is a national musical instrument with ethnic characteristics in Africa. In different African countries, the thumb piano has different names. For example, Kalimba is the name of this instrument in Kenya, while in Zimbabwe it is called Mbira, and in Congo it is called Likembe. It also has names such as Sanza and Thumb Piano. It is mainly named because the thin pieces on the body of the piano are plucked by the thumbs (mainly made of wood, bamboo, and also made of metal in modern development). The traditional thumb piano uses a gourd as a resonator;

[0003] Currently, the key fixing parts of the thumb piano are usually composed of a metal beam in the middle and two wooden sleepers in front of and behind the metal beam. It is necessary to install the keys on the metal beam through machine equipment, which greatly reduces the convenience of assembling the keys.

[0020] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following detailed description of the specific embodiments of the present utility model will be provided in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0021] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element present at the same time. In contrast, when an element is referred to as being "directly" connected to another element, there is no intermediate element.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] As Figure 1 and Figure 2 shown, a thumb piano includes a piano body 1, at least one key fixing member 2, a plurality of keys 3, and a key pressing member 4. The key fixing member 2 is detachably mounted on the piano body 1. The plurality of keys 3 are inserted into the key fixing member 2 in a preset order. The key pressing member 4 is detachably mounted on the top of the key fixing member 2, and the bottom of the key pressing member 2 presses against the plurality of keys 3 to fix the plurality of keys 3 on the key fixing member 2. The key fixing member 2 is made of a metal material, and the metal material is one of steel material or iron material.

[0024] As Figure 3 shown, the key fixing member 2 has a "J"-shaped structure. Installation feet 23 are symmetrically arranged at both ends of the bottom of the key fixing member 2. Installation holes 231 are formed in the installation feet 23, and screws pass through the installation holes 231 and are threadedly connected to the piano body 1. When it is necessary to detach the key fixing member 2 from the piano body 1, the screws can be detached from the installation holes 231. The number of key fixing members 2 can be 1 or 2, and can be set according to the actual number of keys 3. Key insertion interfaces 21 adapted to the number of keys 3 are respectively formed on both sides of the key fixing member 2. The key insertion interfaces 21 near the ends of the keys are lower in horizontal height than the key insertion interfaces 21 far from the ends of the keys. The plurality of keys 3 form a preset inclination angle with the horizontal plane, and the height of the playing ends of the keys 3 is slightly higher, which is convenient for playing.

[0025] In one embodiment, the key pressing member 4 has a "U" - shaped structure. A plurality of screw holes 22 are formed at the top of the key fixing member 2. The mounting screws 5 pass through the screw holes 22 and are thread - connected to the key pressing member 4. Reinforcing ribs are provided on both sides of the screw holes 22. Thread grooves are formed at positions on the key pressing member 4 that are adapted to the screw holes 22. During installation, the thread grooves are thread - connected to the mounting screws 5. The mounting screws 5 can be hexagon screws. The setting of the reinforcing ribs prevents the "almost - shaped" key fixing member 2 from deforming after being squeezed by the mounting screws 5.

[0026] As Figure 1 and Figure 3 shown, Embodiment 1: When installing 17 keys 3, one key fixing member 2 is set. First, the mounting screws 5 can be passed through the screw holes 22 and thread - connected to the thread grooves, so that the key pressing member 4 is assembled to the key fixing member 2. Then, while several keys 3 pass through the key insertion openings 21, the key pressing member 4 exerts pressure on several keys 3, and several keys 3 are fixed to the key fixing member 2.

[0027] As Figure 4 shown, Embodiment 2: When installing 36 keys 3, two key fixing members 2 and two key pressing members 4 are set. The two key fixing members 2 are arranged side by side, one higher and one lower, on the body 1 of the thumb piano;

[0028] First, the mounting screws 5 can be passed through the screw holes 22 and thread - connected to the thread grooves, so that the two key pressing members 4 are respectively assembled to the corresponding key fixing members 2. Then, while some keys 3 pass through the key insertion openings 21 of the higher - positioned key fixing member 2, one of the key pressing members 4 exerts pressure on the keys 3, and some keys 3 are fixed to the higher - positioned key fixing member 2. Then, the remaining keys 3 are sequentially passed through the key insertion openings 21 of the lower - positioned key fixing member 2 and the single - side key insertion openings 21 of the higher - positioned key fixing member 2, so that the other key pressing member 4 exerts pressure on the keys 3, and some keys 3 are fixed to the lower - positioned key fixing member 2. In this way, the keys 3 on the two key fixing members 2 form both a height difference in the vertical direction and a position difference in the horizontal direction, which is convenient for playing the keys 3 of the thumb piano.

[0029] In this way, for the thumb piano, through the cooperative setting of the body 1, the key fixing member 2, several keys 3, and the key pressing member 4, when installing the keys 3, several keys 3 are inserted into the key fixing member 2, and the key pressing member 3 is installed on the key fixing member 2 through the mounting screws 5, and the bottom of the key pressing member 4 presses against the keys 3, then the assembly of the keys 3 can be completed. It is simple and fast, and can be completed manually without using equipment for installation. At the same time, the key fixing member 2 is made of metal material, which can better conduct the vibration of the piano sound to the body 1 of the piano, forming a good sound effect.

[0030] In one embodiment, the length of the key 3 gradually shortens in a preset order and proportion as the musical scale goes from low to high; the width of the key 3 gradually narrows in a preset order and proportion as the musical scale goes from low to high.

[0031] The widths of traditional keys are the same, resulting in unbalanced vibrations, specifically manifested as weak bass, difficult pronunciation of high notes, and prone to situations such as "hollow notes, dead notes, and too low volume".

[0032] In this way, the basic rule of the strings is that high notes are thin and short, while low notes are thick and long. Designing the key 3 into a structure with a wide bass and a narrow treble according to the above rule conforms to the pronunciation rule and can achieve a better playing effect. The arrangement order of the keys 3 in this application can be arranged in order from the low musical scale to the high musical scale from one end of the key fixing member 2 to the other end, or can adopt an arrangement method where the low musical scale keys 3 are in the middle and the high musical scale keys 3 are on both sides.

[0033] In one embodiment, the playing end 31 of the key 3 is an inverted spoon-shaped structure, and the shapes and sizes of the spoon-shaped structures are the same.

[0034] In this way, the playing end of the key 3 of the current ordinary thumb piano is usually a rectangular-like structure, which is likely to cause discomfort to the player's hand after a long time of playing. In this application, the playing end 31 of the key 3 is designed as an inverted spoon-shaped structure. The inverted spoon-shaped structure has a certain arc surface structure, which has a certain buffering effect when contacting the fingers and can effectively reduce the symptoms of hand discomfort.

[0035] In one embodiment, the body 1 of the musical instrument is a mortise and tenon structure piano case or a panel type body.

[0036] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
