Abstract

An earphone having an equalizer function is provided to reproduce a low-pitched sound by opening a second exhaust hole, and to reproduce a high-pitched sound by closing the second exhaust hole. In an earphone having an equalizer function, a tubular supporting unit(3) is coupled to the rear of the earphone. An exhaust hole(2) is perforated on the rear surface of a housing(1) to exhaust vibration air generated when a diaphragm vibrates. A second exhaust hole(4) is perforated at a narrow part(3a) of the tubular supporting unit(3). A sleeve type opening and closing unit(5) having an adjusting hole(6) for opening and closing the second exhaust hole(4) is installed in the narrow part(3a) of the tubular supporting unit(3).

본 발명은 간편한 조작으로 고음 또는 저음 특성의 음색으로 재생할 수 있고, 고음 또는 저음 특성도 자유로이 조절할 수 있게 한 이퀄라이저 기능을 가진 이어폰에 관한 것이다.The present invention relates to an earphone having an equalizer function that can be reproduced in a tone of a high or low tone characteristic by a simple operation, and can also freely adjust the high or low tone characteristic.

휴대폰이나 MP3용 이어폰 수요자는 풍부한 저음을 선호하는 성향이 강하지만, 통상의 휴대폰, MP3용 이어폰은 고정적인 음질로만 청취할 수 있게 설계돼 있어서 풍부한 저음이 고음 재생영역을 침범하는 바람에 저음으로 치우친 음색으로 재생되는 등 단일 재생음질, 즉 저음 특성의 음질을 재생하는 것에 만족할 수밖에 없어 아쉬웠다.Consumers of mobile phones and MP3 earphones tend to prefer abundant bass, but ordinary mobile phones and MP3 earphones are designed to listen only with a fixed sound quality, so that the rich bass is inclined to the bass due to the high sound quality. It was unfortunate to be satisfied with reproducing a single reproducing sound, i.e., a bass character, such as a tone.

이런 실정을 고려할 때, 장래의 이어폰은 청취음의 고음과 저음을 자유로이 선택하여 재생음의 본래 음색대로 청취할 수 있는 방향으로 구조를 개선할 필요성이 대두된다.Considering this situation, there is a need for future earphones to freely select the high and low sounds of the listening sound and to improve the structure in such a way that the original sound of the reproduced sound can be heard.

따라서 본 발명의 목적은 간편한 조작으로 고음 또는 저음 특성으로 재생할 수 있는 이퀄라이저 기능을 가진 이어폰을 제공하는 것이다.Accordingly, an object of the present invention is to provide an earphone having an equalizer function that can be reproduced with high or low pitch characteristics by a simple operation.

이 과제는, 하우징의 뒷면에 천공된 배기공으로 스피커의 진동판이 진동할 때 발생하는 진동공기가 빠져나가게 한 이어폰의 뒤쪽에 관상 지지구가 결합된 것에 있어서, 상기 지지구의 일점에 제2 배기공을 천공하고 지지구상에는 상기 배기공을 개폐하는 슬리브형 개폐구를 설치하여 개폐구를 올려서 제2 배기공을 개방하면 진동판에 의한 진동공기가 더 많이 빠져나가 풍부한 저음이 재생되고 개폐구를 내려서 제2 배기공을 막으면 기존의 하우징측 배기공으로만 진동공기가 배기되어 고음 특성이 부각되도록 한 이퀄라이저 기능을 가진 이어폰으로 달성할 수 있다.The problem is that the tubular support is coupled to the rear of the earphone which allows the vibration air generated when the diaphragm of the speaker vibrates to the exhaust hole drilled on the rear side of the housing, so that the second exhaust hole is provided at one point of the support. When the perforated and the support sphere is provided with a sleeve-type opening and closing opening and closing the exhaust hole to open the opening and closing the second exhaust hole, the vibration air by the diaphragm is more escaped, rich bass is reproduced and the opening and closing the lower exhaust opening If this is prevented, it can be achieved with an earphone having an equalizer function, in which vibrating air is exhausted only through the exhaust hole of the existing housing side, so that high-pitched characteristics are highlighted.

도 1에서, 이어폰의 스피커 하우징(1)의 뒤쪽에는 관상 지지구(3)가 결합되어 있고, 지지구(3)상에는 제2 배기공용 슬리브형 개폐구(5)가 설치되어 있다.In Fig. 1, the tubular support 3 is coupled to the rear of the speaker housing 1 of the earphone, and the sleeve type opening and closing port 5 for the second exhaust hole is provided on the support 3.

개폐구(5)는 바디(7)의 상단에 일체로 형성된 일종의 슬리브이며, 바디(7)의 하단부에 일체로 주어진 링(8)은 상기 바디(7)의 하단에 결합된 코드 보호관(9)에 헐겁게 끼워져 너덜거리지 않게 지지되도록 하는 것이다.The opening and closing hole 5 is a kind of sleeve integrally formed at the upper end of the body 7, and the ring 8 integrally provided at the lower end of the body 7 is connected to the cord protection tube 9 coupled to the lower end of the body 7. It is loosely inserted so that it is supported without being tattered.

도 2에서, 하우징(1)의 뒷면 가장자리에는 방사상으로 배기공(2)이 천공돼 있다.In FIG. 2, the exhaust hole 2 is drilled radially in the rear edge of the housing 1.

이 배기공(2)은 저음 특성을 살리기 위해 기왕부터 존재하던 것이다.This exhaust hole 2 has existed since the beginning in order to utilize the bass characteristics.

상기 지지구(3)에서 잘록한 부위(3a)의 일점에는 제2 배기공(4)이 천공되어 있고, 개폐구(5)는 제2 배기공(4)을 포위하는 형태로 잘록한 부위(3a)에 헐겁게 씌워져 있다.The second exhaust hole 4 is perforated at one point of the concave portion 3a of the supporter 3, and the opening and closing port 5 is formed at the concave portion 3a in the form of surrounding the second exhaust hole 4. It is loosely covered.

잘록한 부위(3a)는 위로 올려서 제2 배기공(4)을 틔우고 제2 배기공(4)이 개방된 상태에서 아래로 내리면 제2 배기공(4)이 닫히게 하는 개폐구(5)의 제2 배기공 개폐활동이 가능하게 지지하는 것으로, 잘록한 부위(3a)의 길이가 곧 개폐구(5)의 활동허용거리다.2nd exhaust of opening / closing opening 5 which raises the narrowed part 3a to close up the 2nd exhaust hole 4, and when the 2nd exhaust hole 4 descends in the state which opened, the 2nd exhaust hole 4 will be closed. The ball opening and closing activity is possible to support, the length of the narrowed portion (3a) is the allowable distance of the opening and closing port (5).

개폐구(5)에는 제2 배기공(4)의 개폐를 결정하기 위한 조절공(6)이 천공되어 있다.The opening and closing port 5 is perforated with an adjusting hole 6 for determining the opening and closing of the second exhaust hole 4.

도 2 및 도 3은 개폐구(5)를 올려서 제2 배기공(4)을 완전히 개방시킨 상태 를 나타낸 것인데, 진동판이 진동할 때 발생하는 진동공기 중의 일부는 하우징(1)의 배기공(2)으로 빠져나가고(a) 다른 일부는 제2 배기공(4)으로 빠져나간다(b).2 and 3 illustrate a state in which the second exhaust hole 4 is completely opened by raising and closing the opening 5, and some of the vibration air generated when the diaphragm vibrates is the exhaust hole 2 of the housing 1. (A) and the other part exits to the second exhaust hole (4).

이와 같이 제2 배기공(4)을 개방하면 진동판이 진동할 때 발생하는 진동공기가 더 많이 빠져나가게 되고, 이에 따라 고음 영역을 침범하던 진동공기의 영향이 감소돼 풍부한 저음으로 재생하게 된다.When the second exhaust hole 4 is opened in this way, more vibration air generated when the diaphragm vibrates is released, thereby reducing the influence of the vibration air invading the high-pitched region, thereby reproducing rich bass.

제2 배기공(4)이 열린 상태에서 도 4 및 도 5와 같이 개폐구(5)를 완전히 내려 제2 배기공(4)을 막으면 진동공기는 기존의 배기공(2)으로만 빠져나가(a) 고음 특성이 나타나게 된다.When the second exhaust hole 4 is opened and the opening and closing hole 5 is completely lowered to block the second exhaust hole 4 as shown in FIGS. 4 and 5, the vibrating air escapes only through the existing exhaust hole 2 ( a) The treble characteristic is displayed.

고음 및 저음 특성은 제2 배기공(4)과 조절공(6)이 어긋나 폐쇄되거나 겹쳐져 개방되도록 해서 조절한다.The high and low sound characteristics are adjusted by shifting the second exhaust hole 4 and the adjustment hole 6 so as to be closed or overlapped and opened.

이상 설명한 바와 같이, 이퀄라이저 기능이 부가된 본 발명의 이어폰은 하우징의 뒤쪽에 결합된 관상 지지구의 일점에 천공된 제2 배기공을 개폐구로 계폐시켜 고음 또는 저음 특성을 간단히 선택하여 다양한 음색으로 재생할 수 있으므로 고음 또는 저음 특성을 수요자의 취향에 맞게 자유로이 조절할 수 있는 편의가 제공되는 효과가 있다.As described above, the earphone of the present invention to which the equalizer function is added allows the second exhaust hole perforated at one point of the tubular support coupled to the rear of the housing to be opened and closed to open and close the high or low tone characteristic to reproduce various sounds. Therefore, there is an effect that the convenience to freely adjust the high or low characteristics according to the taste of the consumer is provided.
