Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of five-degree circle turntable tools, and in particular to a musical note indicator turntable for teaching assistance. Background Technology
[0002] In music learning, understanding note relationships and fretboard positions is a crucial foundation. A note indicator turntable, a teaching aid that visually displays note distribution, the circle of fifths, and helps students quickly locate the corresponding notes on the fretboard, is widely used in music teaching and learning.
[0003] Existing circular fingerboards and circle of fifths turntables typically employ a double-layer design, with the lower turntable displaying various musical notes and the upper turntable displaying them via perforations. However, in practical use, the perforations on the upper turntable are difficult to align precisely with the notes on the lower turntable, often resulting in misalignment. This deviation leads to unclear or incomplete note markings displayed on the upper turntable, and can even cause confusion between adjacent but different notes (such as A and A#). Existing circle of fifths turntables have significant structural design flaws, failing to achieve precise alignment. This makes it easy for learners to make mistakes when learning note distribution patterns, understanding the operation of the circle of fifths, and determining note positions in actual instrument playing. This problem not only reduces learning efficiency but also seriously affects learners' correct grasp of music theory. Utility Model Content

[0027] Example 1:
[0028] like Figures 1 to 6 As shown, a note indicator turntable for teaching assistance includes an upper plate 1 and a lower plate 2 arranged coaxially. The upper plate 1 has several sets of display ports 11 circumferentially arranged along its upper edge, and the lower plate 2 has several note color blocks 21 circumferentially arranged along its upper edge. Each note color block 21 is located on the rotation path of the corresponding display port 11, and the opening area of the display port 11 is not less than the projected area of the corresponding note color block 21.
[0029] Several positioning blocks 4 are fixed circumferentially on the lower plate 2. The ends of the positioning blocks 4 are rounded. Each positioning block 4 and the corresponding note color block 21 are on the same radial direction of the lower plate 2. The back of the upper plate 1 is provided with a number of guide grooves 3 in the same radial direction as the positioning blocks 4. Each guide groove 3 and the corresponding display port 11 are on the same radial direction of the upper plate 1. The guide groove 3 includes a sliding groove 31 and a locking groove 32. The inner wall of the sliding groove 31 is provided with symmetrical double inclined surfaces that gradually shrink towards the locking groove 32. The locking groove 32 is located in the center of the sliding groove 31. Through the cooperation of the positioning blocks 4 and the guide grooves 3, the upper plate 1 and the lower plate 2 can be accurately connected during rotation. The symmetrical double inclined surface design of the sliding groove 31 allows the positioning blocks 4 to slide smoothly into the locking groove 32, fixing the relative positions of the upper plate 1 and the lower plate 2. The display port 11 is aligned with the corresponding note color block 21, ensuring the accuracy of the note indication and avoiding deviations when students learn the distribution rules of notes, understand the operation logic of the circle of fifths, and determine the position of notes in actual instrument playing.
[0030] Additionally, the note color blocks 21 on the lower plate 2 are composed of ukulele or guitar strings, frets, and a sequence. The sequence consists of semicircles of numbers from 0 to 12, with two semicircles forming a ring. Each number in the sequence corresponds to a specific string in the radial fret marking its current position. The upper plate 1, based on the lower plate 2, is distributed according to different fingerings for different scales. The display port 11 shows the specific position of each string in the scale. Following the rules of positional frets, with a maximum of four notes per string, the scale is organized into a scale box. Different colored borders distinguish different positions, and black arrows mark the tonic position. By rotating the upper plate, the black pointer points to different tonics (specific numbers in the sequence), and the corresponding fingering (i.e., note color blocks 21) is displayed in different positions on the upper plate 1. The note names of each degree in the scale are also displayed in the display port 11. The relative rotation of the upper plate 1 and lower plate 2 allows for switching between different keys, achieving the effect of note teaching.
[0031] A handle 5 is fixed in the center of the upper plate 1. A grip sleeve 6 is slidably fitted on the handle 5. The grip sleeve 6 is rotatably connected to the lower plate 2. A fixing ring 51 is provided on the handle 5. Several springs 7 are elastically connected between the fixing ring 51 and the grip sleeve 6. The grip sleeve 6 is controlled by the elastic force of the springs 7 to drive the lower plate 2 to abut against the upper plate 1. The design of the handle 5 and the grip sleeve 6 allows the user to hold it easily. The rotatable connection between the grip sleeve 6 and the lower plate 2 makes it convenient for the user to pull the lower plate 2 to rotate, making the operation simple and intuitive. At the same time, the springs 7 can apply elastic force to the lower plate 2, so that it can abut against the upper plate 1 and push the positioning block 4 to slide on the slide groove 31 until it is inserted into the slot 32, achieving the effect of automatic alignment.
[0032] The end of the grip 6 is provided with several equally spaced guide rods 8, and the guide rods 8 slide through the fixing ring 51. A baffle 81 is fixed on the guide rod 8. The guide rod 8 can limit the grip 6, making its movement smoother and preventing deviation. This makes the rotation accuracy of the lower plate 2 higher, making it easier for the display port 11 to align with the note color block 21. At the same time, the baffle 81 limits the movement distance of the guide rod 8, preventing the gap between the lower plate 2 and the upper plate 1 from being too large, making it easier for the user to judge the relative position of the display port 11 and the note color block 21.
[0033] Example 2:
[0034] Please see Figure 7 A note indicator turntable for auxiliary teaching, in another implementation of the upper plate 1 and lower plate 2 in Embodiment 1, specifically: the note color block 21 on the lower plate 2 is a circle of fifths pattern, and the display port 11 on the upper plate 1 is aligned with the circle of fifths pattern. By rotating the lower plate 2, the number of sharps and flats in different keys and on which specific notes they are located can be quickly determined, realizing convenient teaching of the circle of fifths.
[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
