Zusammenfassung: | The present invention relates to an earphone system with two-unit sound balance. In an earphone, the earphone system comprises: a casing having a hollow structure having a snail-like shape with an opened rear face, and including an upper end portion in which a cable is drawn and an upper stepped surface and a lower stepped surface formed on an inner wall thereof; a cover coupled to a rear surface of the casing; an inner double casing having a first tubular body having a first stepped surface formed on an inner circumference thereof and a lower outer circumference mounted on the upper stepped surface, and a second tubular body integrally formed with the lower outer circumference of the first tubular body, having a second stepped surface formed on an inner circumference thereof, and a lower outer circumference mounted on the lower stepped surface; a base output part inserted into the first tubular body such that a lower end portion thereof is mounted on the first stepped surface; a medium/high tone output part inserted into the second tubular body such that a lower end portion thereof is mounted on the second stepped surface; an acoustic discharge portion protruding so as to pass through one side of the front surface of the casing. Even when conventional casing and cover are used, the earphone system of the present invention can improve the output of the low tone and the medium/high tone.
본 발명은 2-유닛 사운드 밸런스 이어폰시스템에 관한 것으로, 이어폰에 있어서, 배면이 개방된 달팽이 형상의 중공 구조로서 상단부에 케이블이 인입되어 있고, 내부벽에 상부 단차면 및 하부 단차면이 형성된 케이싱과; 상기 케이싱의 배면에 결합된 커버와; 내주연에 제 1 단차면이 형성되어 있으며 상기 상부 단차면에 하단 외주연이 거치된 제 1 관체와, 상기 제 1 관체의 하단 외주연과 일체로 형성되어 있으며 내주연에 제 2 단차면이 형성되어 있고 상기 하부 단차면에 하단 외주연이 거치된 제 2 관체를 갖는 내부 더블케이싱과; 상기 제 1 단차면에 하단부가 거치되도록 상기 제 1 관체에 삽입된 베이스 출력부와; 상기 제 2 단차면에 하단부가 거치되도록 상기 제 2 관체에 삽입된 중고음 출력부와; 상기 케이싱의 전면 일측부에 관통되도록 돌출 형성된 음향 토출구로 구성됨으로써, 종래의 케이싱과 커버를 사용하더라도 저음과 중고음의 출력을 개선할 수 있는 효과가 있다. |
