And it is related to the vent hole 13 installed in the earphone is not affected by the noise from the outside because the hole size of the vent hole 13 is not large.

Description

이어폰용 통기공{omitted}Ventilator for Earphones {omitted}

이어폰은 우리가 흔히 사용하고 있으며 이어폰이 가장 좋은 음을 재생하기위해서는 진동판이 자유롭게 진동할수 있도록 하는 것이 바람직 하지만 종래의 이어폰은 진동판의 뒷부분은 진동을 방해받지않기위해 통기공를 적절히 설치하고 있으나 진동판의 앞부분은 귀에 이어폰을 끼우면 이어폰과 귀구멍 사이의 공간이 밀폐되어 진동판이 진동하면 공기의 진동에 의해 음이 전달되기도 하지만 진동에 의해 배압이 발생하고 있으나 그에 대한 대책이 없어 배압에 의해 진동판의 진동이 방해를 받아 좋은 음의 재생이 불가능하므로 보다 좋은 음의 재생이 가능한 통기공를 설치한 이어폰을 제공하는데 목적이 있다.Earphones are commonly used by us, and it is desirable to allow the diaphragm to vibrate freely in order to reproduce the best sound. However, conventional earphones have vents properly installed at the back of the diaphragm to prevent the vibration from being disturbed. When the earphone is inserted into the ear, the space between the earphone and the ear hole is sealed and when the diaphragm vibrates, sound is transmitted by the vibration of the air, but back pressure is generated by the vibration, but there is no countermeasure, so the vibration of the diaphragm is prevented by the back pressure. Receiving good sound is impossible to receive the purpose is to provide earphones with a ventilator installed to enable better sound reproduction.

진동판은 외부의 압력등의 영향을 받지않는 가장 자유로운 상태에서 완전한 진동으로 좋은 음을 재생하도록 설계되어 있는데 이어폰을 귀에 꽂으면 진동판이 진동할 때 뒷면은 공명 역할도 하고 배압이 외부로 누설되도록 구성되어 있어 배압의 영향을 받지않으나 귀에 꽂힌 앞부분(귓구멍)은 공기가 밀폐되어 진동판이 진동하면 외이에서 내이로 진동이 전달되어 내이에서 소리를 인지하게 되는데 밀폐된 공간에서 진동에 의해 발생된 공기압이 소멸되지않고 배압이 되어 진동판의 진동을 방해하는 역할을 하여 진동판이 설계한 데로 진동을 할수없어 좋은 소리를 재생할 수 없는 문제점이 있다.The diaphragm is designed to reproduce good sound with full vibration in the most free state without being influenced by external pressure. When the earphone is plugged into the ear, the diaphragm acts as a resonance and the back pressure leaks to the outside when the diaphragm vibrates. It is not affected by the back pressure, but the front part (ear hole) which is plugged into the ear is sealed with air, and when the diaphragm vibrates, the vibration is transmitted from the outer ear to the inner ear to recognize the sound from the inner ear. There is a problem that can not play a good sound due to the back pressure without the role of the diaphragm to hinder the vibration of the diaphragm can not vibrate as designed.

상기와 같은 문제점을 해결하기위하여 바람직한 실시예를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve the problems as described above with reference to the accompanying drawings, preferred embodiments are as follows.

이어폰은 보편화 되어 있는 제품으로 근본 구조는 같으나 외형은 천차만별이므로 여기서는 가장 기본적이라고 생각되는 모델을 기준하여 설명한다.Earphones are universal products with the same basic structure but different appearances.

특히 본 발명의 통기공는 위치,크기 개수등을 다양하게 변화시켜 이용할수 있으나 근본적으로 배압을 외부로 배출시키는 작용과 통기공를 통하여 외부와 내부의 압력을 자동으로 균형잡아주는 역할을 하는 같은 기술이므로 여기서는 대표적인 방법으로 설명한다.In particular, the ventilation hole of the present invention can be used by varying the position, the number of sizes, etc. However, since the same technology serves to automatically balance the pressure between the outside and inside through the action of discharging the back pressure to the outside and the ventilation hole here. It demonstrates in a typical way.

If it is inserted into (8), it prevents the inflow of noise from the outside and closes, so that the space between the outer ear (8) and the inner ear (9) becomes a sealed space, and when the diaphragm (2) vibrates in the sealed space, the vibration pressure in the air This pressure is not exhausted from the inner ear 9 and is reflected and acts as a back pressure 11 on the diaphragm 2, thus preventing the diaphragm 2 from vibrating freely, thereby making it impossible to reproduce good sound.

도5는 본 발명의 이어폰 통기공에 의해 배압이 외부로 배출되는 모양을 표시한 부분 단면의 측면도로서 본 발명의 이어폰 통기공에 의해 배압이 외부로 배출되는 모양을 표시한 부분 단면의 측면도로서 이어폰에 외이(8)이 끼워져 있을 때 한부분에 통기공(13)을 설치하여 진동파(10)에 의해 발생된 배압(11)이 통기공(13)의 구멍을 통하여 화살표 방향으로 외부로 베출되도록 구성시켜 배압(11)에 의한 진동판(2)의 진동을 방해할수 없게 되며 이 구멍을 통하여 외기와 연결되므로 내외의 공기압력이 항상 상압으로 균형을 이루게 되며 통기공(13)의 구멍 크기가 크지않으므로 외부로 부터 소음의 영향을 받지 않는다..5 is a side view of a partial cross-sectional view showing a state in which the back pressure is discharged to the outside by the earphone vent hole of the present invention. When the outer ear (8) is fitted in the vent hole 13 is installed in one part so that the back pressure 11 generated by the vibration wave 10 is projected to the outside in the direction of the arrow through the hole of the vent hole (13) It is not possible to prevent the vibration of the diaphragm 2 by the back pressure (11), and because it is connected to the outside air through this hole, the internal and external air pressure is always balanced at normal pressure, and the hole size of the vent hole 13 is not large. It is not affected by noise from the outside.

도6는 본 발명의 이어폰에 통기공가 설치된 모양의 정면도로서 (13)은 통기공,(2)는 진동판,(14)는 통기공,(1)은 앞커버이다.6 is a front view of a vent installed in the earphone of the present invention, 13 is a vent, 2 is a diaphragm, 14 is a vent, and 1 is a front cover.

통기공(13)이 상부에 한개 설치되어 있으나 필요에 따라 다수개를 설치할수도 있고 삼각형 ,반원형등 다양한 형태로 이어폰에 설치하여도 되며 근본적으로는 배압을 소거하고 내외의 공기압력이 항상 상압으로 균형을 이루게 하는 통기공역할을 하는 같은 기술이다.One ventilation hole 13 is installed on the upper part, but it can be installed as many as needed. It can be installed in earphones in various forms such as triangle and semi-circle, and basically eliminates back pressure and balances the internal and external air pressure to normal pressure.
