Description

Technical Field

[0001] This utility model relates to the technology of traditional musical instruments, specifically to a lightweight and improved dulcimer. Background Technology

[0002] Musical instruments are tools that express music through specific timbres and playing techniques. As the physical medium of musical creation, instruments transform abstract musical notes into concrete auditory experiences. The yangqin, a struck string instrument in Chinese folk music, combines universal appeal with local characteristics. It is an indispensable instrument in Chinese folk orchestras, possessing a bright timbre and rich expressiveness, and can be used for solo, ensemble, and opera accompaniment. The yangqin is a struck string instrument with a trapezoidal body and a four-row bridge layout, covering a range of F... 3 It typically has dozens of steel strings, with 3 to 5 strings in each section. It produces sound by striking the strings with two sticks. Its tone has both articulation and penetrating power. When played slowly, it sounds like a mountain spring tinkling, and when played fast, it sounds like a flowing stream. It is known as the "piano in a national orchestra".

[0003] However, the existing 402-type dulcimer is usually large and heavy, making it difficult to carry or move. At the same time, the traditional 402-type dulcimer lacks lower semitones and second notes, making pitch adjustment more complicated and causing more inconvenience for playing. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight and improved dulcimer to solve the problems of existing dulcimers being difficult to carry or transport, lacking sufficient pitches, and causing inconvenience for performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight and improved dulcimer, comprising a dulcimer mechanism and a bridge mechanism and a tuning mechanism respectively mounted on the top of the dulcimer mechanism. The dulcimer mechanism includes a body, a soundboard is mounted on the top of the body, strings are mounted on the top of the soundboard, and the strings are distributed on the top of the bridge mechanism and the tuning mechanism.

[0006] The bridge mechanism includes a high semitone bridge, a high pitch bridge, a middle pitch bridge, a tenor bridge, a bass bridge, and a low semitone bridge, which are sequentially distributed on the top of the piano surface.

[0007] The tuning mechanism includes a left tuning roller and an inclined nut, which are fixedly installed on the top of the instrument. The top of the left tuning roller is equipped with a roller and a pitch-changing brass wheel.

[0008] Furthermore, a cover is hinged to the top of the instrument body, and the cover covers both ends of the strings.

[0009] Furthermore, the surface of the soundboard is coated with a dark paint, and a small bridge is installed on the top of the soundboard. The small bridges are respectively distributed between the treble bridge and the alto bridge, on the top of the alto bridge, and between the alto bridge and the tenor bridge.

[0010] Furthermore, a grouped mortise is installed on one side of the roller, and the grouped mortise fits against the top of the instrument surface.

[0011] Furthermore, the interior of the voice-changing copper car is provided with a through groove, and a support shaft is installed inside the through groove.

[0012] Furthermore, a support base is installed on the top of the instrument surface, and the inclined mortise is fixedly installed on the top of the support base.

[0013] Compared with the prior art, the present invention provides a lightweight and improved dulcimer. By setting up a dulcimer mechanism, while retaining the pitch positions and arrangement of the traditional 402 type dulcimer, the length of the 402 dulcimer is shortened from 1180mm to 1095mm, and the weight is reduced from 16kg to 14.5kg. The size and weight of the instrument are reduced, making it easier to carry. The rollers and pitch-changing brass on the instrument can be used to quickly and finely adjust the pitch in a short stroke. The number of pitch-changing brass is reduced from 7 in the traditional dulcimer to 2, and the length of the brass is shortened from 52mm in the traditional dulcimer to 25mm. The pitch can be quickly adjusted by hand to achieve the function of key change.

[0014] By incorporating an inclined bridge, unlike the traditional 402 type with a uniform height, the inclined bridge allows for a gradual increase in height from low to high notes. This is used to adjust the string angle, balance the pressure of the strings on the bass bridge, and prevent excessive pressure on the bass bridge from causing deformation or excessive string angle from damaging the strings.

[0015] By eliminating the right rolling plate of the traditional 402 dulcimer and widening the bridge spacing, the effective string length of the mid-low range notes is increased, resulting in a fuller mid-low frequency tone than the traditional 402 dulcimer.

[0016] By adopting a new pitch layout, compared with the traditional 402-type dulcimer, it adds four pitches a1, d1, ьB, and ьA to the high, middle, tenor, low, and semitone keys respectively. This adds a semitone and expands the two-tone range, resulting in a better tone despite its small size, making it easier to play and bringing more convenience to users. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] Example 1:

[0029] This utility model provides a lightweight and improved dulcimer, including a dulcimer mechanism 1 and a bridge mechanism 2 and a tuning mechanism 3 respectively mounted on the top of the dulcimer mechanism 1. The dulcimer mechanism 1 includes a body 11, a soundboard 14 is mounted on the top of the body 11, and strings 12 are mounted on the top of the soundboard 14. The strings 12 are distributed on the top of the bridge mechanism 2 and the tuning mechanism 3.

[0030] The bridge mechanism 2 includes a high semitone bridge 21, a high pitch bridge 22, a middle pitch bridge 23, a tenor bridge 24, a bass bridge 25, and a low semitone bridge 26, which are distributed sequentially on the top of the soundboard 14.

[0031] The tuning mechanism 3 includes a left tuning roller 31 and an inclined nut 38, which are fixedly installed on the top of the soundboard 14. A roller 32 and a pitch-changing brass wheel 34 are respectively installed on the top of the left tuning roller 31.

[0032] As can be seen from the above, by utilizing the smaller size and weight of the instrument body 11 compared to the traditional dulcimer, it is easier and less strenuous to carry and operate. By placing the instrument body 11 on the instrument stand, the instrument is played by striking the strings 12 with the bamboo sticks. The strings 12 are supported by the high semitone bridge 21, high semitone bridge 22, middle semitone bridge 23, tenor bridge 24, bass bridge 25, and low semitone bridge 26, which enables playing operations in various registers.

[0033] By supporting the strings 12 with grouped mountain passes 33, the length of the multiple strings 12 in each group can be unified. By pushing the rollers 32 and the pitch-changing brass carriages 34 on the top of the instrument body 11, the pitch can be quickly and finely adjusted in a short stroke. The pitch-changing brass carriages 34 are triangular in shape, which makes it easy for the fingers to pinch the slopes on both sides, and can be pushed and moved relatively easily. This can change the support distance for the strings 12, and can be used to adjust the pitch relatively quickly, thus achieving the function of transposition. During the adjustment process, it can also effectively avoid contact between the fingers and the strings 12, and avoid friction between the fingers and the strings 12 during movement, which could cause damage to the fingers. This improves the safety of pitch adjustment. The number of pitch-changing brass carriages 34 has been reduced from 7 in the traditional dulcimer to 2, and the length has been shortened from 52mm in the traditional dulcimer to 25mm. The pitch can be quickly adjusted by hand to perform transposition operations, making the pitch adjustment operation time-saving and labor-saving.

[0034] The inclined sluice gate 38 is set from low to high, which can gradually increase the height from low to high notes. It is used to adjust the angle of the string 12, balance the pressure of the string 12 on the bass bridge 25, and prevent the bass bridge 25 from being deformed due to excessive pressure or the string 12 from being damaged due to excessive angle. It can effectively improve the service life of the string 12 and reduce the trouble caused by maintenance.

[0035] By widening the bridge spacing of the bridge mechanism 2, the effective string length of the mid-low range notes can be increased, resulting in a fuller mid-low frequency tone than the traditional dulcimer, which can effectively improve the listening quality and enhance the appreciation effect.

[0036] By adopting a new pitch layout, compared with the traditional dulcimer, four additional pitches a1, d1, ьB, and ьA are added to the high pitch 22, middle pitch 23, tenor pitch 24, low pitch 25, and low semitone pitch 26 respectively. This adds a low semitone, expands the two-tone range, and while reducing the size of the instrument body 11, it still has a better tone, making it easier to play, increasing the range, and bringing more convenience to the user.

[0037] From the appendix Figure 2 It can be seen that the top of the instrument body 11 is hinged with a cover 13, which covers both ends of the strings 12.

[0038] As can be seen from the above, by flipping the lid 13 upwards, it is convenient to maintain the fixed position between the strings 12 and the soundboard 14, as well as to adjust the tension of the strings 12.

[0039] For details, please refer to the appendix. Figure 2 As shown, the surface of the soundboard 14 is coated with a dark paint, and a small bridge 27 is installed on the top of the soundboard 14. The small bridge 27 is distributed between the treble bridge 22 and the alto bridge 23, on the top of the alto bridge 23, and between the alto bridge 23 and the tenor bridge 24.

[0040] As can be seen from the above, by using a dark-colored piano surface 14, the player can more clearly observe the position of the strings 12, effectively reducing the visual impact of dark shadows on the player, avoiding operational errors on the strings 12, and improving the convenience of playing.

[0041] For details, please refer to the appendix. Figure 3 As shown, a grouped slit 33 is installed on one side of the roller 32, and the grouped slit 33 is attached to the top of the instrument surface 14.

[0042] As can be seen from the above, by pushing the roller 32, the grouping gate 33 can be moved synchronously. By moving the grouping gate 33, the support distance on the string 12 can be changed, and the pitch adjustment operation can be performed relatively quickly.

[0043] Working principle: By placing the body 11 on the stand for support, the roller 32 and the tuning peg 34 can quickly change the key in a short stroke. During the adjustment of the pitch, the fingers are less likely to come into contact with the strings 12 and rub against each other, which can avoid damage to the fingers. The inclined nut 38 can conveniently compensate for the support of the strings 12 on the bass bridges 25 on both sides, and can gradually increase the height from low to high notes. It can be used to balance the pressure of the strings 12 on the bass bridges 25 and prevent deformation due to pressure. The four positions a1, d1, ьB, and ьA are added to the treble bridge 22, alto bridge 23, tenor bridge 24, bass bridge 25, and low semitone bridge 26, respectively.

[0044] Example 2:

[0045] Reference Appendix Figure 4 As shown, the interior of the voice-changing copper car 34 has a through groove 36, and a support shaft 35 is installed inside the through groove 36.

[0046] As can be seen from the above, the string 12 can pass through the through groove 36. The support shaft 35 and the through groove 36 are rotatably installed, which enables the support shaft 35 to have a rotation function. The support shaft 35 can provide rolling support for the string 12. When the variable pitch brass carriage 34 is pushed to move, it can cooperate with the rolling action of the support shaft 35 to easily adjust the support distance for the string 12, and quickly perform pitch adjustment operation, bringing more convenience to the user.

[0047] Reference Appendix Figure 5 As shown, a support base 37 is installed on the top of the soundboard 14, and an inclined mortise 38 is fixedly installed on the top of the support base 37.

[0048] As can be seen from the above, the support base 37 can be fixed at the top of the soundboard 14, which can conveniently support the inclined nut 38, allowing the inclined nut 38 to support the string 12 and balance the pressure of the string 12 on the bass bridge 25.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
