Description

Technical Field

[0001] The invention relates to the technical field of thumb pianos, and in particular to a novel thumb piano. Background Art

[0002] The thumb piano is a musical instrument originated from Africa. Different regions in Africa have different names for it, such as Mbira, Kalimba, Thumbpiano, Likembe, etc. Due to its small size, easy to learn and simple operation, the thumb piano is very popular among some music lovers around the world and has formed a large-scale market worldwide.

[0003] The thumb piano generally includes a piano body, 1-2 rows of metal shrapnel and a piano stand. The piano stand includes two front and rear nut and a bridge. The shrapnel is placed on the front and rear nut. The bridge between the two nut presses the shrapnel downward to keep the shrapnel under a certain tension.

[0004] Press the shrapnel with the thumbs of both hands and then release it to produce sound through vibration, which is mainly used for accompaniment. The shrapnel of the existing thumb piano is directly fixed on a solid wooden board. The timbre of the thumb piano of this structure is relatively clear and cannot produce a rich timbre. Summary of the invention

[0005] In view of the above-mentioned technical problems, the present technical solution provides a new type of thumb piano, which can effectively solve the above-mentioned problems.

[0006] The present invention is achieved through the following technical solutions:

[0007] A new type of thumb piano comprises an integral piano body and a piano stand fixed on the integral piano body, on which a shrapnel for playing music is mounted; the integral piano body comprises a drum skin arranged on the top surface, and a general support fixed on the lower side of the drum skin for supporting the drum skin; the drum skin is closed and fixedly connected to the general support to form a sound cavity opening downward; the piano stand is fixed at the middle of the drum skin.

[0008] Furthermore, the total support includes an upper support and a lower support, and the upper support and the lower support are adjustably fixedly connected.

[0009] Furthermore, the edge of the drum skin is fixed on the outer side wall of the lower support, and a gap is provided between the drum skin and the outer side wall of the upper support.

[0010] Furthermore, a rounded corner is provided between the top surface of the upper support and the outer wall.

[0011] Furthermore, the outer diameter of the upper support is slightly smaller than the outer diameter of the lower support; a groove is provided on the top surface of the upper support, and the groove extends from the middle of the upper support to the inner wall of the upper support.

[0012] Furthermore, the outer diameter of the upper support is 0.1-2 mm smaller than the outer diameter of the lower support; and the inner wall depth of the groove is 0.5-3 mm.

[0013] Furthermore, the upper support is provided with a plurality of fixing holes for fixing, which are located at positions corresponding to the fixing holes, and the lower support is provided with a through hole; adjustment holes for adjusting the gap between the upper support and the lower support are evenly distributed between the through holes; the inner walls of the fixing holes and the adjustment holes are provided with internal threads.

[0014] Furthermore, the piano stand includes a bottom plate fixed on the top surface of the drum skin, and a front nut, a rear nut and a bridge installed on the top surface of the bottom plate, and the spring sheet is installed between the front nut, the rear nut and the bridge.

[0015] Furthermore, the top surface of the base plate is provided with limiting grooves for limiting the front nut and the rear nut at the positions of the front nut and the rear nut; and mounting holes are provided at the mounting positions of the bridges, and the bridges are fixed to the base plate by fasteners.

[0016] Furthermore, the bottom surface of the drum skin is provided with a fixing plate which cooperates with the bottom plate and is fixed, and the fixing plate is provided with positioning holes; the fasteners penetrate the bridge, the bottom plate and the drum skin, and are connected and fixed with the positioning holes on the fixing plate.

[0017] Compared with the prior art, the novel thumb piano proposed by the present invention has the following beneficial effects:

[0018] The arrangement of the drum skin in the technical solution enables the musician to play the shrapnel with his thumb to vibrate the shrapnel, and the vibration of the shrapnel drives the bottom plate and the drum skin to vibrate at the same time, so that the sound of the thumb piano can be thicker and louder; furthermore, when the thumb piano is held in the hand and played, the sound cavity formed between the drum skin and the total support can make the sound waves generated by the vibration of the drum skin hit the inner wall of the sound cavity and then be reflected back into the air, so that the sound waves rotate in the sound cavity to form a simulated echo state; thus, the sound of the thumb piano can be more ethereal, mellow and more pleasant to the ears.

[0019] In this technical solution, the total support is set as an upper support and a lower support that are adjustable and fixedly connected. This is because the drum skin has different tension and relaxation in cold and hot environments due to the principle of thermal expansion and contraction. In order to achieve a better sound for the thumb piano, musicians need to adjust the tension and relaxation of the drum skin. The upper support and the lower support that are adjustable and fixedly connected can meet the needs of musicians in this regard.

[0020] In the present technical solution, when adjusting the upper support and the lower support, the fasteners in the fixing holes between the upper support and the lower support can be loosened or removed first, and then the depth of the fasteners in the adjustment holes can be adjusted with tools; the top surface of the end of the fastener in the adjustment hole is against the bottom surface of the upper support, and when the fastener in the adjustment hole is deeper, the upper support is lifted up, thereby adjusting the gap between the upper support and the lower support; thereby achieving the purpose of adjusting the tension of the drum skin.

[0021] In the present technical solution, the outer diameter of the upper support is slightly smaller than the outer diameter of the lower support, and the design of the groove on the top surface of the upper support is for more convenient adjustment of the tension of the drum skin; in addition, the rounded corners set between the top surface of the upper support and the outer wall can reduce the friction of the drum skin when adjusting the tension of the drum skin, thereby protecting the drum skin.

[0022] The design of the limiting groove on the top surface of the bottom plate in the present technical solution can serve as a limiting groove for the nut; at the same time, it is also convenient for production workers to prevent the nut from rolling and shifting when installing the nut, and it is more convenient to limit the nut and install the spring piece, thereby increasing production efficiency.

[0023] The setting of the fixing plate in the technical solution can further fix the bottom plate on the drum skin, making the bottom plate more firmly fixed. In addition, the fastener runs through the bridge, the bottom plate and the drum skin, and is connected and fixed with the positioning hole on the fixing plate, which can increase the parts of the thumb piano and also reduce the installation steps of the thumb piano, further increasing the production efficiency.

DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Under the premise of not departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solutions of the present invention should all fall within the protection scope of the present invention. Example 1

[0033] like Figure 1-3 As shown, a new type of thumb piano comprises a piano body and a piano bracket fixed on the piano body, and a shrapnel 7 for playing music is installed on the piano bracket.

[0034] The entire body of the instrument includes a drum skin 1 arranged on the top surface, and a general support 2 fixed on the lower side of the drum skin 1 for supporting the drum skin 1; in the present embodiment, the general support 2 is an elliptical frame with a through hole in the middle; the drum skin is fixedly connected to the top of the general support 2 in a closed manner to form a sound cavity opening downward.

[0035] The total support 2 includes an upper support 21 and a lower support 22, and the upper support 21 and the lower support 22 are adjustably fixedly connected. Four fixing holes for fixing are provided on the bottom surface of the upper support 21, which are respectively provided at the diagonal positions, and the inner walls of the fixing holes are provided with internal threads; at the positions corresponding to the fixing holes, a through-fixing through hole 221 is provided on the lower support 22. The fastening screw passes through the fixing through hole 221 and is fixed to the fixing hole.

[0036] On the lower support 22, a plurality of adjustment holes 222 for adjusting the gap between the upper support 21 and the lower support 22 are evenly distributed between the fixed through holes; the inner wall of the adjustment hole 222 is provided with an internal thread. The evenly distributed adjustment holes 222 are to make the gap between the upper support 21 and the lower support 22 the same, so that the drumhead 1 can be evenly distributed.

[0037] When adjusting the upper support 21 and the lower support 22, the fastener in the fixing hole 221 between the upper support 21 and the lower support 22 can be loosened or removed first, and then the depth of the fastener in the adjustment hole 222 can be adjusted with a tool; the fastening screw in the adjustment hole 222, the top surface of the end of the fastening screw is against the bottom surface of the upper support 21, when the fastener in the adjustment hole is deeper, the upper support 21 is lifted up, thereby adjusting the gap between the upper support 21 and the lower support 22; thereby achieving the purpose of adjusting the tension and relaxation of the drum skin 1.

[0038] The outer diameter of the upper support 21 is slightly smaller than the outer diameter of the lower support 22, and the outer diameter of the upper support 21 is 0.1-2mm smaller than the outer diameter of the lower support 22. The edge of the drum skin 1 is fixed to the outer wall of the lower support 22 by gluing, and a gap is formed between the outer wall of the drum skin 1 and the upper support 21. A groove 214 is provided on the top surface of the upper support 21, and the groove 214 extends from the middle of the upper support 21 to the inner wall of the upper support 21, and the inner wall depth of the groove 214 is 0.5-3mm. The contact area between the upper support 214 and the drum skin 1 can be reduced, and when adjusting the tension of the drum skin 1, the friction between the drum skin 1 and the upper support 21 can be effectively reduced, so that the musician can use very little force to complete the adjustment of the tension and relaxation of the drum skin, and the adjustment operation of the tension and relaxation of the drum skin can be completed more conveniently.

[0039] A rounded corner 213 is provided between the top surface of the upper support 21 and the outer wall 211. The provision of the rounded corner 213 makes the top surface of the upper support 21 and the outer wall more rounded. When the tension of the drum skin 1 is adjusted, the rounded corner 213 can reduce the damage to the drum skin 1 when the drum skin 1 is displaced, and play a protective role on the drum skin 1.

[0040] The drum skin 1 is fixed on the top surface of the total support 2, and the piano bracket is fixed on the middle of the drum skin 1. In order to facilitate the user to grab the thumb piano more comfortably and play, the piano bracket is fixed at a position slightly above the middle of the drum skin 1.

[0041] The piano support comprises a bottom plate 3 fixed on the top surface of the drum head 1, a front nut 4, a rear nut 5 and a bridge 6 installed on the top surface of the bottom plate 3; and a spring piece 7 is installed between the front nut 4, the rear nut 5 and the bridge 6.

[0042] On the top surface of the bottom plate 3, a limiting groove 31 for limiting and fixing the front nut 4 and the rear nut 5 is provided at the positions of the front nut 4 and the rear nut 5; a mounting hole 32 is provided at the installation position of the saddle 6, and the saddle 6 is fixed on the bottom plate 3 by a fastener. The design of the limiting groove 31 and the mounting hole 32 can limit the nut and the saddle 6; at the same time, it is also convenient for the production workers to quickly find the position for installing the nut and the saddle, thereby increasing the accuracy. In addition, the design of the limiting groove also allows the assembler to directly place the nut in the limiting groove when installing the nut, thereby avoiding the rolling and displacement of the nut, and making it more convenient to limit the nut and install the spring piece, thereby increasing the production efficiency.

[0043] The piano bracket also includes a fixing plate 8 installed on the bottom surface of the drum skin 1 and fixed with the bottom plate 3; a positioning hole 81 is set on the fixing plate 8, and the fastening screws pass through the piano bridge 6, the bottom plate 3 and the drum skin 1, and are connected and fixed with the positioning hole 81 on the fixing plate 8.

[0044] The setting of the fixing plate 8 can further fix the bottom plate 3 on the drum head 1, so that the bottom plate 3 is fixed more firmly. In addition, the fasteners penetrate the bridge, the bottom plate and the drum head, and are connected and fixed with the positioning holes on the fixing plate, which can increase the parts of the thumb piano and also reduce the installation steps of the thumb piano, further increasing the production efficiency.
