On Dec. 30, 2104 and Jul. 6, 2015, the same inventor filed two other patents, rather similar but not identical, that both were registered on 19th of August, 2015, with the numbers KR1015458230000 and KR1015458350000

So, both patents claim for a 'relatively long sound path' or a 'relatively long acoustic passage', as source of a 'wide bandwidth'/'wide acoustic band'.

The second patent deals with a more complex system, still dedicated to set the fipple size. Here, there is a whole hollow insert in the lower part of the nose flute.
The author explains that 'conventional nose flutes' include a body in which « the throttle 120 [on the 1st patent drawings] is coupled slidably to 117 to depression introduced into inlet hole (111a) » [according to Google translate...].
In order to improve que sound quality of the model presented in the first of this pair of patents, Mr. Kwang Hyun Jang proposes the version described the second one. However, I must say I don't understand how it works. This insert is bezeled and cannot slide. The Google translation of the description is total gibberish:
« Nose flutes is improved sound quality according to the present invention for achieving the above object, the rear upper portion has the first discharge which is a part of the inflow kotbaram ball the inlet exhaust and the inlet holes formed in close contact with the nose portion, the rear lower portion the ball body is formed in close contact with the mouth area; The inside is provided on the front of the body and guide so that a portion of kotbaram introduced through the inlet hole is discharged to the lower surface outside of the body, and guide so that the other part of the kotbaram is discharged into a ball of the first discharge, yet the kotbaram the other part includes a passage member passage is formed to guide to discharge toward the front of the body, said passage member and the passage top (上端 部) is in the lower end surface (下 端面) of said inlet ball and communicates and lower end of the body communicating with the outer and middle portions may be respectively communicated with the front outer side of the first exhaust hole and the body. »
If someone can explain to me, I would appreciate a lot.

« Nose flutes 100 according to this embodiment is easily to carry, and to the engaging side of the front upper end of the body (110), (110b) can be formed, engaging with (110b) has latching sphere (50) ( It may be a lower portion of FIG. 5) to be inserted.»
'Ambiance' views in both paents [click on the images to magnify]:
« Conventional nose flute includes a body 110 and the throttle 120. »
Have you noticed the use of the word 'conventional' ? Have you ever seen so many nose flutes with such a sliding system ? OK, there were the ones by Cornelius Degen or some old patents, but were they really 'conventional' ?
We will get the answer to this question in the Part II !
