Description

Auto Half {AUTOHARP}

The present invention relates to an auto-half, and more particularly, to a structure of an auto-half that is easy to use for education for adults as well as children because it is light in weight and small in size while generating more rich reverberation and sound.

Autoharp (aka Chromaharp) is an instrument in C major that uses an absolute scale played with an open string. It can sound one'note' per string and uses an absolute scale that only sounds an open string'note'. . However, in order to produce an open-string note, it is not an instrument that makes a sound immediately like a piano. It is an instrument that is played by indirectly making a sound by pressing a chord and flicking to find a note to produce the composition of the chord. string), so the'tick-tick' distance may include noise or noise such as the sound of iron.

In addition, since the auto harp has not yet been widely distributed to adolescents, this is due to not only the limitations of the sound, but also because of the heavy weight and inconvenience of carrying. Because of this, it is becoming an obstacle to educational activities for adolescents or children.

There are examples of miniaturized so-called mini auto halfs, but most of them are made for decorative purposes, and the structure is made by cutting the upper and lower plates made of plywood to the struts on the left and right sides, and the sound is bad. There is a side where it is difficult to play for each key because it is not applied. There have been attempts to use it as an educational instrument for kindergarten children, but the arrangement of scales and chords is insufficient, and the problem of having to play only in the high-pitched range by raising a note by one octave and the size of an instrument that is not suitable for kindergarten children is uncomfortable. As a result, its use as a musical instrument for children's education was sluggish.

A preferred embodiment for implementing the auto half of the present invention will be described below with reference to the drawings.

1 and 2 show a general and basic appearance and structure of an auto half (aka chroma half). As shown, the structure of the auto half consists of a body post consisting of a plurality of posts constituting the skeleton of the auto half between the upper plate 1 and the lower plate 2, and has a sealed sound space inside. When the string (4) is bounced, sound is transmitted to the inside through the sound hole (11) formed in the upper plate (2), and the internal reverberation comes out through the sound hole (11) again to generate sound.

A sound hole 11 is formed in the center of the top plate 1, and a tuning pin 12 for adjusting the tension of the string 4 passes through the top plate 1 and is placed in the frame of the body support. It is equipped with a number of strings (4) according to the number. Below the tuning pin 12, a plurality of upper strings 13 supporting the upper part of the string 4 are fixed and provided according to the number of strings 4, and the lower tension of the strings 4 is supported at the lower end. Hahyeonjoo 14 for accommodating and supporting the hahyeonjoo 14 and a hahyeonjoo pedestal 15 for receiving and supporting the hahyeonjoo 14 are formed from one end to the other end and provided. Between the sound hole 11 and the hahyeonju 14, a chord portion 5 capable of pressing a chord is formed across from one side to the other in the vertical direction of the strings 4, and the chord portion 5 is (4) It includes a cord bar 51 formed over the cover and a chord button 52 and a cord cover 53 fixed to the upper plate 2.

3 to 9 are views showing in detail the components of the body post 3 and the body post 3, which are the core structures of the auto half of the present invention.

As shown in Fig. 3, the body support (3) of the auto half of the present invention includes a tuning pin bridge frame (31) that is coupled to the top in a diagonal direction, and a left abutment (32) that is coupled to the left end in a vertical direction. And, it is composed of a right post 33 coupled in the vertical direction to the right end and the Hahyeon-ju bridge frame 42 coupled in the horizontal direction to the lower end, and the frame and the post are frame and post with mutually adjacent frame and post. A structure that can be easily combined with each other is formed, and by connecting and bonding with each other, a closed hollow space is formed inside as shown in FIG. 3.

4 to 6 are views showing in detail the structure of the tuning pin bridge frame 31 and various changeable embodiments. As shown in FIG. 4, both side ends have a structure suitable for coupling with adjacent posts, and a plurality of tuning pintle sound holes 311 are formed on the inner side at regular intervals in the longitudinal direction.

The tuning pintle sound hole 311 and the sound holes formed inside the frame and the post are sound resonating holes for transmitting the sound inside the auto half to the body post. When playing with finger picking, the sound holes receive the vibration of the top plate through the inside of the body and evenly transmit the resonance to the body support, creating a more purified and beautiful sound of the support. It enriches and significantly reduces noise.

In addition, since the sound holes are formed in a large number on the frame and the support, the density of the body support 3 is significantly reduced, thereby reducing the weight of the entire instrument. Since the weight can be reduced, the thickness of the body holding stand 3 can be extended by about 40 millimeters, and since the frequency can be greatly expanded by widening the width of the inner barrel, a more abundant volume can be generated. According to the practice, the weight of the conventional instrument was about 2705 grams, but the weight of the auto half according to the present invention can be reduced to about 1730 grams, thereby reducing the weight of about 975 grams.

The tuning pintle sound hole 311 and the following frame and the sound hole of the post may have various sizes and shapes, but preferably the diameter of the auto half is between about 1.4 to 1.6 cm and the depth of about 2 to 3.5 cm. Considering the size, it may be formed in an appropriate size.

5 and 6 are views showing various modifications of the tuning pin bridge frame 31. Figure 5 shows that the tuning pin frame bottom hollow portion 312 is formed in the longitudinal direction on the side of the tuning pin bridge frame 31 joined to the lower plate 2, and Figure 6 is the tuning pin bridge frame 31 It is shown that a plurality of tuning pintle bottom hollow holes 313 are formed side by side in the longitudinal direction on the side to be joined with the lower plate (2) of the bottom of the. The tuning pintle bottom hollow part 312 and the tuning pin bottom hollow hole 313 have the effect of enriching the sound resonant, but their main function is to form a space in the tuning pin bridge frame 31 having a high density, It is a configuration aimed at reducing weight. The preferred position where the tuning pintle bottom hollow portion 312 and the tuning pin bottom hollow hole 313 are formed should be formed by avoiding the location of the portion where the tuning pin is placed so as not to weaken the supporting force of the tuning pin.

7 is a view showing in detail the inner side of the left post (32). As shown in FIG. 7, both side ends have a structure suitable for coupling with adjacent posts, and a plurality of left posts sound holes 321 are formed on the inner side at regular intervals in the longitudinal direction. The structure and function of the left strut sound hole 321 may refer to the structure and function of the tuning pintle sound hole 311 described above.

8 is a view showing in detail the inner side of the right post (33). As shown in Fig. 8, both side ends have a structure suitable for coupling with adjacent posts, and a plurality of right post sound holes 331 are formed on the inner side at regular intervals in the longitudinal direction. The structure and function of the right prop sound hole 331 may refer to the structure and function of the tuning pintle sound hole 311 described above.

9 is a view showing in detail the upper surface of the bridge frame 34 Ha Hyun-joo. As shown in Fig. 9, both side ends have a structure suitable for coupling with adjacent posts, and unlike the sound holes of the posts, a plurality of sub-barrier sound holes 341 are located under the upper surface of the bridge frame that is in contact with the upper plate 1. ), and a hahyeonju receiving hole 342 for accommodating the hahyeonju 14 is formed above the hahyeonjutle sound hole 341. The hahyeonju frame sound hole 341 is not formed as an inner surface so as not to weaken the supporting force of the hahyeonju 14, but is formed on the upper surface of the hahyeonju bridge frame in contact with the upper plate 1. The hahyeonjutle sound hole 341 directly receives the resonance from the upper plate 1 to form a sound resonance and transmits the resonance to the hahyeonju bridge frame.

By forming the spacing between the strings 4 of the auto harp of the present invention to be 6 millimeters, noise can be further reduced by allowing the adjacent strings to be smoothly rubbed during finger picking. This is because the spacing of the strings 4 of the conventional auto harp is 6.3 to 6.5 mm, and this is because the noise increases because the strings 4 are scratched more strongly if the strings are wider.

In addition, in order to further widen the range of the auto harp of the present invention, a string for generating C# (degree #) and D (re) sounds was further included, following the highest sound C (degree) of the conventional 36-string instrument. By configuring it with strings, it is possible to play a more diverse range of songs.

In addition, the material of the tuning pin bridge frame 31, the left strut 32, the right strut 33, and the Hahyeonju bridge frame 34, which are the configuration of the body support 4 of the present invention, reduce the weight of the auto half. It will be possible to construct a material of paulownia wood, which is an optimized material for generating high-quality sound resonant.
