Numbers cited in the examples below are not limited to the objects of citation and can be applied to all examples. An object that has the same purpose and effect as the configuration presented in the examples is an equivalent replacement object. The high-level concept presented in the examples includes low-level concept objects that are not described.

(Example 1-1) The present invention relates to a harp that implements a chromatic scale, and includes a resonance portion 100 through which one end of the string is penetrated and fixed; A fixing part 200 extending from the resonance part 100 and fixing the other end of the string; Includes.

The present invention relates to a harp on which a player plays music using a plurality of strings of different lengths. Stringed instruments that use multiple strings can be classified into stringed instruments, string instruments, and percussion instruments depending on the playing method. The harp is a musical instrument that produces sound by plucking strings. Strings of different lengths are fixed to a frame and the player plucks the strings to create music. In other words, as the length of each string is different, the sound frequency implemented by the string is formed differently.

At this time, due to the structural characteristics of the strings, a problem arises in that the size of the sound produced by each string is limited. Accordingly, the present invention can be formed as a structure including a separate resonating part 100 extending the fixing part 200 that fixes a plurality of strings of different lengths.

That is, as one end of the plurality of strings is coupled to the resonance unit 100 and the other end is coupled to the fixing part 200, the sound produced by the plurality of strings vibrating is generated by the resonance unit 100. can be amplified.

(Example 1-2) The present invention relates to a harp that implements a chromatic scale. In Example 1-1, the resonance part 100 has a void formed inside, and an inlet hole through which one end of the string passes is formed on one side. A housing 110 formed in; Includes.

(Example 1-3) The present invention relates to a harp that implements a chromatic scale. In Example 1-2, one end of the string is formed in a structure that is fixed to the other inner surface of the housing 110.

The present invention relates to a resonance unit 100 that amplifies the volume of sound realized by a plurality of strings. As one end of the string is coupled to the resonating part 100, which is formed as an integrated or combined structure with the fixing part 200, the size of the sound produced by each string can be amplified.

At this time, the resonance unit 100 may be formed in a structure including a housing 110 in which an inlet hole is formed, and one end of a string penetrating the inlet hole is inserted into the empty space inside. In other words, the sound produced by the string vibrating is partially amplified within the housing 110 and output to the outside.

(Example 1-4) The present invention relates to a harp that implements a chromatic scale, and in Example 1-2, the resonance part 100 is disposed on the outer periphery of the inlet hole, and a string penetrating the inlet hole. a bearing in contact with the outer periphery of; Includes.

(Example 1-5) The present invention relates to a harp that implements a chromatic scale, and in Example 1-4, the friction coefficient of the bearing is formed to a value smaller than the friction coefficient of the housing 110.

The present invention relates to a resonance unit 100 that amplifies the volume of sound realized by a plurality of strings. As one end of the string penetrates and is fixed in the inlet hole formed in the housing 110, the size of the sound generated by the string vibrating may be amplified inside the housing 110 and output to the outside.

At this time, due to the typical structural characteristics of the harp, each string, one end of which is coupled to the housing 110, may be formed in a structure that contacts the inner periphery of the inlet hole. When the above phenomenon is continuously repeated, the string may be damaged due to friction between the string and the housing 110.

In order to solve the above problem, the resonance unit 100 may be made of a material with a friction coefficient smaller than that of the housing 110 and may include a bearing disposed on the inner periphery of the inlet hole.

In Example 1-1, the fixing portion 200 protrudes along the thickness direction and is coupled to the other end of the string, respectively. A tuning unit 210 that controls the tension applied to the strings; Includes.

The present invention relates to a fixing part 200 that fixes the other end of a string, one end of which is coupled to the resonating part 100. As both longitudinal ends of the string are fixed by the resonance unit 100 and the fixing unit 200, a certain tensile force is applied to each string. Therefore, sound can be output to the outside due to an impact transmitted from the outside to the string.

In order to implement the above-described technology, the fixing unit 200 may include a tuning unit 210 that fixes the other end of the string. At this time, the tuning unit 210 is formed in a structure that protrudes from one surface in the thickness direction of the fixing unit 200, thereby preventing mutual interference between the frame constituting the fixing unit 200 and a plurality of strings.

As the fixing part 200 is formed with a structure including the tuning part 210, the positions of a plurality of strings of different lengths are determined so that the performer can play music.

At this time, if the string vibrates repeatedly for a long period of time to produce sound, the tensile force given to each string may decrease. In other words, a scale that is somewhat different from the performer's intention can be output. Therefore, it is desirable that the tuning unit 210 be formed in a structure capable of maintaining the tension applied to each string at any time.

In order to implement the above-described technology, the tuning unit 210 has a structure in which the winding part 211 protruding from one surface in the thickness direction of the fixing part 200 and the tuning pin 212 derived from the other surface rotate around the same rotation axis. can be formed. That is, as the player rotates the rotation axis of the tuning pin 212 while the other end of the string is wound around the outer periphery of the winding portion 211, tension can be restored to each string. At this time, the tuning pin 212 is preferably formed in a structure that protrudes from the other surface in the thickness direction of the fixing part 200 so as not to overlap the string.

(Example 3-1) The present invention relates to a harp that implements a chromatic scale. In Example 2-1, the fixing part 200 is disposed at the lower part of the tuning part 210, and is attached to each string.

As both longitudinal ends of the string are fixed by the resonance unit 100 and the fixing unit 200, a certain tensile force is applied to each string. Therefore, sound can be output to the outside due to an impact transmitted from the outside to the string.

There are a total of 12 musical scales within one octave, including 7 diatonic scales and 5 chromatic scales. At this time, if there are strings for all scales within the octave, the overall size of the harp will increase, making it less portable, and at the same time, when played using the arpeggio technique often implemented in the harp, an uncomfortable sound that is somewhat out of harmony with harmonic music will be produced. There is a problem with how it can be implemented.

Accordingly, the fixing unit 200 of the present invention includes a semitone implementation unit 220 capable of selectively implementing semitones for each string, thereby solving the above-mentioned problems.

In order to implement the above-mentioned technology, the semitone realization unit 220 may be formed in a structure in which a rotating plate 221 having a structure through which a string passes is disposed at the lower end of the tuning unit 210. At this time, the rotation axis of the rotation plate 221 may be formed in a direction parallel to the rotation axis through which the tuning pin 212 transmits rotational force to the winding unit 211. That is, as the communication hole 221-1 formed inside the rotating plate 221 along the longitudinal direction of the string rotates at a predetermined angle by the rotating shaft, the sound of the string can be raised by a semitone by additionally supplying tension to the string. .

(Example 3-6) The present invention relates to a harp that implements a chromatic scale, and in Example 3-4, the cross section of the rotating plate 221 is formed in a circular shape.

At this time, the cross section of the rotation plate 221 is preferably formed in a circular shape with a constant distance value in all directions about the rotation axis. By forming the above-mentioned structure, it is possible to minimize the phenomenon of the string being damaged by the edge portion in contact with the outer circumference of the string.

The string, the other end of which is fixed by the tuning unit 210, can selectively receive additional tension by the semitone realization unit 220. In other words, when the string supplied with tension by the semitone implementation unit 220 vibrates, it outputs a scale that is a semitone higher than the existing tone, ultimately securing the diversity of scales output within the harp.

At this time, the fixing unit 200 may be formed in a structure including a semitone driving unit 230 that selectively activates the semitone implementing unit 220. That is, when the performer wishes to output a scale raised by a semitone for the relevant string, he or she can activate the semitone implementation unit 220 through the semitone driving unit 230.
