Description

Technical Field

[0001] The present application relates to the technical field of tuners, and more specifically, to a folk music disc tuner. Background Art

[0002] The twelve-tone equal temperament, also known as the "twelve-interval temperament", is a universal temperament system in the world that divides a group of notes (octave) into twelve semi-tone intervals. The wavelength ratio between two adjacent notes is exactly equal. The twelve-tone equal temperament was discovered by Zhu Zaiyu, the prince of the Ming Dynasty in China. He divided the octave interval into twelve equal parts according to the wavelength ratio. Each part is called a semitone (minor second), and two semitones make up a whole tone. In the twelve-tone equal temperament, a semitone is the smallest pitch distance in the twelve-tone equal temperament organization, and the distance between two notes equal to two semitones is called a whole tone.

[0003] Currently, a disc tuner is required as an auxiliary learning tool for the twelve-tone equal temperament. However, due to its integrated structure, the existing disc tuner is difficult to be effectively disassembled, inspected and maintained when needed.

[0004] In order to solve the above problems, the present application provides a folk music disc tuner. Utility Model Content

[0028] Example:

[0029] The present application embodiment discloses a folk music disc tuner, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, comprising a main disk 1, a first turntable 2 is provided on one side of the main disk 1, and a second turntable 3 is provided on the other side of the main disk 1, and the center points of the main disk 1, the first turntable 2 and the second turntable 3 are on the same reference axis, a first through hole 4 is provided at the center of the main disk 1, and a clamping groove 7 is provided on the side wall of the first through hole 4, a second through hole 5 is provided at the center of the first turntable 2, and a third through hole 6 is provided at the center of the second turntable 3, and an assembly cylinder 8 is movably inserted through the inner walls of the first through hole 4, the second through hole 5 and the third through hole 6, and a clamping block 9 is fixedly installed on the outer side wall of the middle part of the assembly cylinder 8, and the inner walls on both sides of the assembly cylinder 8 are provided with internal threads, and locking structures are symmetrically provided on both side ends of the assembly cylinder 8;

[0030] The main disk 1, the first rotating disk 2, and the second rotating disk 3 are all in a circular disk-shaped structure, and the diameters of the main disk 1 and the second rotating disk 3 are equal, while the diameter of the first rotating disk 2 is smaller than the diameters of the main disk 1 and the second rotating disk 3. Four card slots 7 and card blocks 9 are provided, and the four card slots 7 and card blocks 9 are evenly distributed on the outer side of the middle part of the assembly cylinder 8, and each card slot 7 and card block 9 are mutually card-engaged and adapted.

[0031] The locking structure includes a rotating wheel 10 located at one end surface of the assembly cylinder 8, a stud 11 is fixedly connected to the center position of one side of the rotating wheel 10, and the outer wall of the stud 11 is screwed to one side end of the assembly cylinder 8 through an internal thread. The two rotating wheels 10 are respectively abutted against the end surfaces of the first rotating disk 2 and the second rotating disk 3 that are away from each other, and the side walls of the two rotating wheels 10 are uniformly provided with a plurality of anti-slip grooves;

[0032] The first turntable 2 and the second turntable 3 are fixedly mounted with a slide ring 12 on their opposite end faces. The slide ring 12 has a semicircular ring structure, and the arc surface on one side of the slide ring 12 is in sliding contact with the side wall of the main disk 1. The setting of the slide ring 12 can effectively slide and limit the first turntable 2 and the second turntable 3 on the two side surfaces of the main disk 1, and can also effectively reduce the sliding wear problem of the two on the two side surfaces of the main disk 1, thereby improving the overall service life.

[0033] The implementation principle of this embodiment is: when in use, one side of the integral disc regulator is pentatonic syllables, and the other side is heptatonic syllables, combining the twelve-tone equal temperament with the fifth-harmonic temperament, and the first turntable 2 or the second turntable 3 is rotated on the end surface of the main disc 1, and when one tone is determined, other related tones can be known, which is applicable to all musical instruments except the guzheng;

[0034] When the whole needs to be disassembled for inspection and maintenance, it is only necessary to use the rotation of the studs 11 by the rotating wheels 10 on both sides in turn to make both of them detach from the two side ends of the assembly cylinder 8, and then the first turntable 2 and the second turntable 3 can be removed from the two sides of the main disk 1. Under the clamping cooperation of each clamping block 9 and the clamping groove 7, when the whole is in a complete assembled state and in use, the first turntable 2 and the second turntable 3 are operated and rotated on the outer walls of the two sides of the assembly cylinder 8, and it is ensured that the main disk 1 will not rotate on the outer wall of the assembly cylinder 8.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
