AI Technical Summary
During the tuning process of the existing thumb piano, the pillow bar has a limited height, which causes the hammer to strike unsteadily and the grip to be unstable, making it difficult to complete the tuning quickly.
A combination structure of a first pillow bar and a second pillow bar is adopted. The first pillow bar is "L"-shaped and the second pillow bar is "U"-shaped. One end of the metal bar is placed on the first pillow bar, and the other end is placed on the part of the second pillow bar where there is no hole, and is locked by fasteners. The second pillow bar presses against the metal bar to keep it stable, and the extended part provides a gripping point to increase the hammering space.
It improves the stability and accuracy of tuning, increases the space for the hammer to strike, and provides a better grip point for quick and easy tuning.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thumb pianos, in particular to a thumb piano which is easy to tune. Background Art
[0002] The carlimba, also known as the kalimba, is a distinctive African folk instrument. Its sounding body consists of a series of elastic metal bars of varying lengths, producing different wavelengths of sound, while a wood or gourd-shaped resonance box acts as the base. During use, the carlimba requires frequent tuning by striking the ends of the metal bars with a hammer to adjust their length.
[0003] At present, with regard to the structure of the existing thumb piano, specifically Chinese patent CN202220375994.5 discloses a nine-key mini thumb piano. This patent only provides two pillow bars on the resonance box for the installation of the metal bars, and then allows one end of all the metal bars to be placed on the two pillow bars respectively, and then the fixed beam presses the metal bars downward to complete the installation of the metal bars. When tuning is required, a small hammer is used to strike the two ends of the metal bars respectively. However, due to the limited height of the pillow bar, the space provided will also be limited, so the hammer drop will be limited, and when tuning, the grip of the thumb piano can also clamp the two sides of the resonance box, so that a more stable grip cannot be provided when hammering. The unstable grip easily causes inaccurate hammering, resulting in the inability to complete the tuning quickly. Utility Model Content
[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a thumb piano that is easy to tune.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A thumb piano that is easy to tune, includes a resonance base, a first pillow bar, a second pillow bar and a metal bar, wherein the first pillow bar is "L"-shaped, and the bottom of the first pillow bar is locked to the resonance base by a fastener, the second pillow bar is "U"-shaped, and both ends of the second pillow bar are facing upward, and the second pillow bar is located at one end close to the first pillow bar and is provided with a number of through holes corresponding to the number of metal bars, one end of the metal bar passes through the through holes and is placed on the upper end of the first pillow bar, and the middle part of the metal bar is placed on the end of the second pillow bar that is not provided with the through holes, wherein the middle part of the second pillow bar is locked to the resonance base by a fastener, and as the fastener is locked, the second pillow bar presses all the metal bars, causing the metal bars to deform to keep them firmly placed.
[0007] Preferably, the second pillow strip is provided with an extension portion extending in a horizontal direction at the top end of the end provided with the through hole.
[0008] Preferably, the distance from the top end of the first pillow bar to the surface of the resonance base is equal to 5 cm.
[0009] Preferably, the fastener is a screw.
[0010] Preferably, a rope threading hole is provided on the resonance base.
[0011] Due to the above-mentioned solution, the present invention uses the first and second pillow bars to form a mounting structure for the metal bar. On the one hand, this eliminates redundant components, allowing the second pillow bar to serve both a supporting and a pressing role. On the other hand, the L-shaped design of the first pillow bar allows the other end of the metal bar to be at a higher height, creating more space between the metal bar and the resonance base, thereby better meeting the requirements of hammer-type tuning. At the same time, an extension portion is also provided on the second pillow bar, which provides the user with more gripping points, facilitating a more stable grip when tuning.

[0017] like Figure 1 and Figure 2 As shown, the present embodiment provides a thumb piano that is easy to tune, comprising a resonance base 1, a first pillow bar 2, a second pillow bar 3 and a metal bar 4, wherein the first pillow bar 2 is in an "L" shape, and the bottom of the first pillow bar 2 is locked on the resonance base 1 by a fastener 5, the second pillow bar 3 is in a "U" shape, and both ends of the second pillow bar 3 are facing upward, and the second pillow bar 3 is located at one end close to the first pillow bar 2 and is provided with a number of through holes 6 corresponding to the number of metal bars 4, one end of the metal bar 4 passes through the through holes 6 and is placed on the upper end of the first pillow bar 2, and the middle part of the metal bar 4 is placed on the end of the second pillow bar 3 where no through holes 6 are provided, wherein the middle part of the second pillow bar 3 is locked on the resonance base 1 by the fastener 5, and as the fastener 5 is locked, the second pillow bar 3 presses all the metal bars 4, causing the metal bars 4 to deform to keep them firmly placed, and the fastener 5 is a screw.
[0018] In this embodiment, the first pillow bar 2 and the second pillow bar 3 form a mounting structure for the metal bar 4. On the one hand, redundant components are eliminated, allowing the second pillow 3 to play both a supporting role and a pressing role. On the other hand, relying on the L-shaped design of the first pillow bar 2, the other end of the metal bar 4 can be at a higher height, so that there is a larger space between the metal bar 4 and the resonance base 1, thereby better meeting the hammer-type tuning needs.
[0019] Furthermore, in order to allow the fingers to grip better, the second pillow bar 3 of this embodiment is provided with an extension part 7 extending in the horizontal direction at the top end of the end where the through hole 6 is provided. In this way, relying on the setting of the extension part 7, the thumb or other fingers can be placed there when gripping, so that the grip can be more secure when tuning and hammering.
[0020] Furthermore, with regard to the height design of the top of the first pillow bar 2, in this embodiment, the distance d from the top of the first pillow bar 2 to the surface of the resonance base 1 is equal to 5 cm. Thus, the tuning requirements can be met with a space of 5 cm.
[0021] Furthermore, in order to facilitate carrying, a rope threading hole 8 is provided on the resonance base 1 of this embodiment.
[0022] The above are only preferred embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
