Hereinafter, referring to the background technology together with the accompanying drawings as follows.

In the past, audio has been a staple of the home. The level of distribution, quality, and size of TV were not very satisfactory, and there were not many other leisure methods as they are now, so listening to music or radio using audio became a major hobby. At that time, I heard an LP board using a turntable instead of a CD, so the audio at that time was often called'the full-length recorder', and there were many large sizes that were placed in the living room.

As semiconductor technology improved including transistors and small media such as cassette tapes and CDs came out, the size of fixed-type audio for homes gradually decreased.Audio that was reduced in size by digitizing or excluding additional functions such as level meters using such small media is called mini-component. Call. Mini-components have greatly increased the market size by casually entering the small living room of newlyweds or the study room of teenagers. Desktop cassettes, which are smaller in size than mini-components and support large batteries, which can be carried outdoors, were also popularly sold.

However, as computer-based media such as MP3 became more popular, and the types of leisure life in the home became more diverse, it is now common for home living rooms to not have large audio. Mini-components have also given way to small smart devices such as iPods and iPhones. Mini-components that are coming out now are popular with models that focus on linking functions with smartphones, and CD and MP3-only models are mostly. In addition, there are also ways to enjoy music that are difficult to see with proprietary audio such as PC-Fi, so the possibility of the audio market regaining its former reputation is not very high.

In general, home fixed audio is close to stagnation, but the high-end audio market is still there as music listening is a relatively classy hobby in terms of society.

The above audio is equipped with a speaker, and a speaker grill is used to protect the speaker driver of such a speaker. If the speaker grill is made of a material such as hard wire mesh or plastic, sound from the speaker driver can easily pass through. Therefore, the function of protecting the speaker driver may be more excellent when the speaker grill is made of a solid material, but there is a problem that adversely affects the sound quality of the reproduced sound.

On the other hand, a speaker grill made of cloth (hereinafter referred to as'speaker cloth') can easily pass the sound of the entire band except for the high treble and high treble, and it is not perfect, but it is somewhat expensive. It has been used for a long time because it can protect the speaker driver from the risk of damage.

Since the conventional speaker cloth as described above is woven in a plain weave using weft and warp, there is a disadvantage in that the thread is well loosened.

In addition, the conventional speaker cloth has a disadvantage that it is difficult to sew when sewing on a speaker because the thread is loose.

In addition, the conventional speaker cloth is difficult to maintain the spacing between the weft yarns and the spacing between the warps when receiving an external force, so that the shape is changed, and accordingly, the appearance is not good and there is a disadvantage of adversely affecting the sound quality of the reproduced sound.
