However, in order to make an open string sound, it is not an instrument that sounds like a piano, but rather an instrument that presses chords and finds the sound that you want to make the chords indirectly and plays indirectly. strings can be touched, and the 'tick' distances may include noise or noise, such as vocal sounds.

In addition, AutoHalf has not yet been widely distributed to adolescents, not only because of the limitation of the sound, but also due to the heavy weight and inconvenience of carrying. For this reason, it is an obstacle to educational activities for adolescents or children.

There is an example of miniaturized so-called mini auto half, but most of them are made for decorative purpose, and its structure is made by cutting the upper and lower boards made of plywood on the left and right sides of the support stand, and the sound is bad. There is a side that is difficult to play by key because it is not correct. There was an attempt to use it as an educational instrument for kindergarten children, but there was a lack of arrangement of musical scales and chords. Due to this, the use as a musical instrument for children was sluggish.

Sound holes formed inward in the tuning pintle sound hole 311 and the frame and the support stand are sound ring holes for transmitting the sound inside the auto half to the support body. The sound holes receive the tremor vibration of the top plate evenly through the inside of the body when it is played by finger picking, and evenly transmits the sound to the body prop, creating a more purified beautiful sound of the pedestal. It enriches the noise and significantly reduces noise.

In addition, since the sound holes are formed in a plurality of frames and props, the density of the body props 3 is significantly reduced, thereby reducing the weight of the entire instrument. Since the weight can be reduced, the thickness of the body prop 3 can be extended by about 40 millimeters, and the width of the inner cylinder can be widened to greatly increase the frequency, thereby generating more abundant volume. 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 could be reduced to about 1730 grams, and thus the weight reduction effect of about 975 grams could be enjoyed.
