Abstract

The present invention relates to an earplug to provide white noise where a hole is drilled in the center to allow a double filter to be inserted therein to block large noise and increase small white noise, so as to enable ventilation due to the hole, and have a structure with sufficient room, which relives the burden on a user's ear since there is no need to fill the inside of the ear.

Description

노이즈 귀마개{noise earplug}Noise earplugs {noise earplug}

본 발명은 백색소음을 제공하는 귀마개에 관한 것이다.The present invention relates to earplugs that provide white noise.

근로자가 작업하고 있을 때 발생하는 소음에 의해서 청력장해를 받을 우려를 보호하는 도구이다. 음파의 진동수가 높을수록 많이 흡수하는 성질을 가지고 있다.It is a tool to protect workers from the possibility of hearing impairment due to noise generated when they are working. The higher the frequency of the sound wave, the more it absorbs.

백색소음은 넓은 주파수 범위에서 거의 일정한 스펙트럼을 가지는 신호로 불규칙한 패턴과 적당한 소음인 것이 특징이다. 귀에 쉽게 익숙해져 오히려 거슬리는 소음을 덮어주는 역할을 한다.White noise is a signal with an almost constant spectrum in a wide frequency range, and is characterized by irregular patterns and moderate noise. It is easy to get used to, and it serves to cover the noise that is rather intrusive.

유럽특허 제 19208744.3European Patent No. 19208744.3 미국특허 제 16713811US Patent No. 16713811

본 발명의 목적은 종래기술의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 귀마개의 본질인 소음 차단부분이 날이갈수록 발전하는데 오히려 소음이 없으면 심리적안정을 찾지못하는 사람들에게 이롭 게 하고, 실제 백색소음은 집중력향상효과가 존재하기때문에 그 부분을 살리고자 하는 것이다.An object of the present invention is to solve the problems of the prior art, and the object of the present invention is to benefit people who do not find psychological stability without noise, while the noise blocking part, which is the essence of earplugs, develops day by day. Noise has a concentration enhancing effect, so we want to save that part.

귀마개는 보통 소음 제거를 위해 귀와 접촉하는 부분에 빈틈이 존재하지 않는다. 이 때문에 귀에 습기가 차는 등 문제가 생기는데, 본 발명은 중앙에 구멍을 뚫고 필터로 소리를 거르는 식이기 때문에 귀 건강에 이롭다.Earplugs usually do not have gaps in the part that comes into contact with the ear to eliminate noise. This causes problems such as moisture in the ears, but the present invention is beneficial to ear health because it filters sound through a filter with a hole in the center.

이중필터 구성으로 1차는 55db 이상의 큰 소음을 어느정도 잡아주고 2차적으로는 작은 백색소음과 동시에 db이 큰 소음들을 25db에 수렴하게 한다. With a dual filter configuration, the primary captures loud noises of 55db or more, and the secondary converges small white noise and large db noises to 25db.

착용에 대한 피로감을 최대한 덜어주기 위해 귓 속 귓속 모양에 가장 알맞은 모양새로 만든다. In order to reduce fatigue from wearing as much as possible, it is made in the most suitable shape for the shape of the inner ear.

본 발명에 따르면, 백색소음으로 인한 집중력 향상으로 일률강화와 새로운 구조로 만들어진 모양으로 기존에 귀마개에 존재하는 문제점인 통풍이 안되는점을 개선하고 소음을 인위적인 소리로 변형시키는 게 아니라 귀에 쉽게 익숙해져 편안함을 가져오게 하는 효과가 있다.According to the present invention, the improvement of concentration due to white noise improves uniformity and a new structure, which improves the lack of ventilation, which is a problem existing in earplugs, and does not transform noise into artificial sound, but is easily accustomed to the ear and is comfortable. has the effect of bringing about

도 1은 본 발명에 의한 노이즈 귀마개의 도면이다.1 is a diagram of a noise earplug according to the present invention.

도 1에는 본 발명에 의한 노이즈 귀마개가 도시되어 있는데, 중앙에 구멍(1,4)을 뚫고 필터(2,3)로 소리를 거르는 식이기 때문에 귀 건강에 이롭도록 되어 있다. 1 shows a noise earplug according to the present invention, which is beneficial to ear health because it is a type in which holes 1 and 4 are drilled in the center and sound is filtered through filters 2 and 3.

이중필터 구성으로 1차 필터(2)는 55db 이상의 큰 소음을 어느정도 잡아주고, 2차 필터(3)는 작은 백색소음과 동시에 db이 큰 소음들을 25db에 수렴하게 한다. With a dual filter configuration, the first filter (2) catches loud noises of 55db or more to some extent, and the second filter (3) converges small white noise and noises with large db to 25db.

또, 본 발명은 이중필터를 접합시켰기 때문에 필터가 들어가는 곳에 통풍구간을 만들어 장시간 착용시 귀에 생기는 부담감과 질병등을 예방할 수 있고, 1차 필터에서는 55db이상의 소리를 낮게 잡아주어 밸런스를 맞추고, 2차 필터에서는 25db미만의 백색소음은 크고 55db미만의 소음은 작게 맞추어 25db에 최대한 수렴하게끔 설계되어 있다.In addition, since the present invention combines double filters, a ventilation section is created where the filter enters to prevent burden and disease in the ears when worn for a long time. In the filter, white noise of less than 25db is large, and noise of less than 55db is set to be small, and it is designed to converge to 25db as much as possible.
