이하, 첨부도면을 참조하여 본 발명에 대해 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

설명에 앞서, 여러 실시예에 있어서, 동일한 구성을 가지는 구성요소에 대해서는 동일 부호를 사용하여 대표적으로 제1 실시예에서 설명하고, 그 외의 실시예에서는 제1 실시예와 다른 구성에 대해서만 설명하기로 한다.Prior to the description, in the various embodiments, components having the same configuration will be representatively described in the first embodiment using the same reference numerals, and in other embodiments, only the configuration different from the first embodiment will be described. do.

도 1 내지 도 3에는 본 발명의 제1 실시예에 따른 이어패드가 도시되어 있다. 이들 도면에 도시된 바와 같이, 본 발명의 제1 실시예에 따른 이어패드(10)는 이어패드 몸체(11), 삽입 헤드(21), 한 쌍의 트레드(31)를 포함한다.1 to 3 show an ear pad according to a first embodiment of the present invention. As shown in these figures, the ear pad 10 according to the first embodiment of the present invention includes an ear pad body 11, an insertion head 21, and a pair of treads 31.

이어패드 몸체(11)는 일정 길이의 원기둥 형상을 가진다. 이어패드 몸체(11)의 내주에는 이어패드 몸체(11)의 길이방향을 따라 관통공(13)이 관통 형성되어 있다. 이어패드 몸체(11)의 관통공(13)은 이어폰(1, 도 5참조)에서 발생하는 음파의 진행을 위한 통로 역할을 하며, 이에 따라 이어패드 몸체(11)는 통상의 울림판 역할을 한다.The ear pad body 11 has a cylindrical shape of a predetermined length. Through-holes 13 are formed in the inner circumference of the ear pad body 11 along the longitudinal direction of the ear pad body 11. The through hole 13 of the ear pad body 11 serves as a passage for the progress of the sound waves generated in the earphone 1 (see FIG. 5), and thus the ear pad body 11 serves as a conventional sounding plate.

또한, 이어패드 몸체(11)에는 이어폰(1)이 착탈가능하게 결합된다. 관통공(13)의 내주면에는 일정 폭을 가지며 고리형상으로 돌출된 단차부(15)가 형성되어 있다. 관통공(13)의 단차부(15)에 이어폰(1)이 결합됨에 따라, 이어패드(10)와 이어폰(1)은 견고하게 결합되어 외력에 의해 이어패드(10)는 이어폰(1)으로부터 쉽게 빠지지 않게 된다.In addition, the earphone 1 is detachably coupled to the ear pad body 11. An inner circumferential surface of the through hole 13 has a predetermined width and is formed with a stepped portion 15 protruding in an annular shape. As the earphone 1 is coupled to the stepped portion 15 of the through hole 13, the ear pad 10 and the earphone 1 are firmly coupled so that the ear pad 10 is detached from the earphone 1 by external force. It does not fall easily.

삽입 헤드(21)는 이어패드 몸체(11)의 일단부의 외주에 일체로 돌출 형성되어, 외이도에 삽입된다. 삽입 헤드(21)는 외이도에 삽입이 용이하도록 전체적으로 반구형의 단면형상을 가진다.The insertion head 21 protrudes integrally with the outer circumference of one end of the ear pad body 11 and is inserted into the ear canal. Insertion head 21 has a hemispherical cross-sectional shape as a whole to facilitate insertion into the ear canal.

한편, 도 3에 도시된 바와 같이, 본 발명의 제1 실시예에 따른 이어패드(10)의 삽입 헤드(21)는 이어패드 몸체(11)와의 사이에 이격 공간(23)을 형성하며, 이어패드 몸체(11)의 일단부로부터 이어패드 몸체(11)의 길이방향을 따라 일체로 연장 형성되어 있다.On the other hand, as shown in Figure 3, the insertion head 21 of the ear pad 10 according to the first embodiment of the present invention forms a separation space 23 between the ear pad body 11, It extends integrally along the longitudinal direction of the ear pad body 11 from one end of the pad body 11.

이와 같이, 이어패드 몸체(11)와 삽입 헤드(21) 사이에 이격 공간(23)이 형성됨에 따라, 이어패드 몸체(11)이 관통공(13)으로 전달되는 소리에 의해 이어패드 몸체(11)에 발생하는 진동은 삽입 헤드(21)에 의해 감쇄되지 않게 되고, 이어패드 몸체(11)의 관통공(13)을 통해 전달되는 소리 증폭의 저하 없이 외이도로 전달할 수 있게 되어 양질의 풍부한 음을 전달할 수 있다.As such, as the separation space 23 is formed between the ear pad body 11 and the insertion head 21, the ear pad body 11 is formed by the sound transmitted from the ear pad body 11 to the through hole 13. Vibration generated in the) is not attenuated by the insertion head 21, and can be transmitted to the ear canal without degrading the amplification of sound transmitted through the through hole 13 of the ear pad body 11, thereby producing a rich sound of high quality. I can deliver it.

여기서, 이어패드 몸체(11)는 반구형의 단면형상을 갖는 것으로 도시되어 있지만 이에 한정되지 않으며, 타원형의 단면형상을 가질 수도 있다.Here, the ear pad body 11 is shown as having a hemispherical cross-sectional shape, but is not limited thereto, and may have an elliptical cross-sectional shape.

한편, 도 4에는 본 발명의 삽입 헤드(21')의 제2 실시예에 따른 이어패드가 도시되어 있다. 본 발명의 제2 실시예에 따른 이어패드(10')는, 전술한 제1 실시예와 달리 이어패드 몸체(11)와 삽입 헤드(21') 사이에 이격 공간(23)이 형성되지 않고, 삽입 헤드(21')는 이어패드 몸체(11)와 일체로 형성되어 있다.4 shows an ear pad according to a second embodiment of the insertion head 21 'of the present invention. In the ear pad 10 ′ according to the second embodiment of the present invention, a space 23 is not formed between the ear pad body 11 and the insertion head 21 ′, unlike the first embodiment described above. The insertion head 21 'is integrally formed with the ear pad body 11.

이와 같이, 이어패드(10')가 이어패드 몸체(11)와 삽입 헤드(21') 사이에 소정의 이격 공간(23)없이 이어패드 몸체(11)와 삽입 헤드(21')가 일체로 형성된 경우, 이어패드 몸체(11)이 관통공(13)으로 전달되는 소리에 의해 이어패드 몸체(11)에 발생하는 이어패드 몸체(11)의 진동이 삽입 헤드(21')에 의해 감쇄되어, 도 3에 도시된 본 발명의 일 실시예에 따른 이어패드(10)에 비해 상대적으로 소리의 증폭 효과가 저하되지만, 이어패드 몸체(11)의 강성이 증대되어 내구성이 향상된다.As such, the ear pad 10 'is integrally formed with the ear pad body 11 and the insertion head 21' without a predetermined space 23 between the ear pad body 11 and the insertion head 21 '. In this case, vibration of the ear pad body 11 generated in the ear pad body 11 by the sound transmitted from the ear pad body 11 to the through hole 13 is attenuated by the insertion head 21 '. Compared to the ear pad 10 according to the exemplary embodiment of the present invention shown in FIG. 3, the sound amplification effect is relatively lowered, but the rigidity of the ear pad body 11 is increased to improve durability.

한 쌍의 트레드(31)는 링 형상을 가지며, 삽입 헤드(21)의 반대방향에 위치하는 이어패드 몸체(11)의 외주면에 간격을 두고 형성된다. 한 쌍의 트레드(31)는 관통공(13)의 축선에 대해 외이도로의 삽입방향을 향해 하향 경사진 경사부(33)를 가진다. 이에, 본 발명의 일 실시예에 따른 트레드(31)는 전체적으로 삼각형의 단면형상을 가진다.The pair of treads 31 have a ring shape and are formed at intervals on the outer circumferential surface of the ear pad body 11 positioned in the opposite direction of the insertion head 21. The pair of treads 31 has an inclined portion 33 inclined downward toward the insertion direction of the ear canal with respect to the axis of the through hole 13. Thus, the tread 31 according to the embodiment of the present invention has a triangular cross-sectional shape as a whole.

이와 같이, 트레드(31)가 삼각형의 단면형상을 가짐에 따라, 외이도로 이어패드(10)의 삽입이 원활하게 이루어지고, 또한 트레드(31)와 외이도 내벽 사이의 마찰에 의해 삽입 헤드(21)의 반대방향으로의 움직임이 억제되어, 쾌적하고 안정적인 착용감을 제공할 수 있게 된다.Thus, as the tread 31 has a triangular cross-sectional shape, the ear pad 10 is smoothly inserted into the ear canal, and the insertion head 21 is caused by friction between the tread 31 and the inner ear canal wall. Movement in the opposite direction of is suppressed, thereby providing a comfortable and stable fit.

또한, 한 쌍의 트레드(31)의 외경은 삽입 헤드(21)의 외경보다 크게 형성되어 있다. 그리고, 한 쌍의 트레드(31)는 삽입 헤드(21)의 반대방향을 향할수록 외경이 점진적으로 증대되는 단면형상을 가진다. 이에 의해, 트레드(31)와 외이도 내벽 사이의 밀착력이 더욱 향상되어, 외부의 소음이 외이도로 유입되는 것을 차폐할 수 있을 뿐만 아니라 외이도의 크기에 관계없이 이어패드(10)를 착용할 수 있게 되어, 사용자의 편의성이 증대된다.In addition, the outer diameter of the pair of treads 31 is larger than the outer diameter of the insertion head 21. In addition, the pair of treads 31 has a cross-sectional shape in which the outer diameter gradually increases as it faces the opposite direction of the insertion head 21. As a result, the adhesion between the tread 31 and the inner wall of the ear canal is further improved, which not only prevents external noise from flowing into the ear canal, but also makes it possible to wear the ear pad 10 regardless of the size of the ear canal. User convenience is increased.

그리고, 본 발명에 따른 이어패드(10)는 트레드(31)의 수량을 최소화함으로써 예컨대, 한 쌍의 트레드(31)를 구비함으로써, 이어패드 몸체(11)의 관통공(13)을 통해 전달되는 소리의 증폭이 저하되는 것을 줄어 양질의 풍부한 음을 전달할 수 있다.In addition, the ear pad 10 according to the present invention is transmitted through the through hole 13 of the ear pad body 11 by minimizing the quantity of the tread 31, for example, by having a pair of treads 31. The amplification of the sound is reduced, and abundant sound can be delivered.

여기서, 트레드(31)는 삼각형의 단면형상 대신에 원형 또는 다각형의 단면형상을 가질 수 있다. 그리고, 한 쌍의 트레드(31)는 동일한 외경을 가질 수 있다.Here, the tread 31 may have a circular or polygonal cross-sectional shape instead of a triangular cross-sectional shape. In addition, the pair of treads 31 may have the same outer diameter.

또한, 트레드(31)는 도 5의 본 발명의 제3 실시예에 따른 이어패드(10")에 도시된 바와 같이, 전술한 제1 실시예와 달리 하나만 마련될 수도 있다. 이로써, 전술한 제1 실시예에 비해 상대적으로 이어패드 몸체(11)의 관통공(13)을 통해 전달되는 소리의 증폭이 저하되는 것을 더 줄일 수 있게 된다.In addition, unlike the first embodiment described above, only one tread 31 may be provided as shown in the ear pad 10 ″ according to the third embodiment of the present invention of FIG. 5. Compared to the first embodiment, the amplification of the sound transmitted through the through hole 13 of the ear pad body 11 can be further reduced.

본 발명에 따른 이어패드(10)는 외이도 내벽에 신축가능하게 밀착하며, 외이도의 내벽에 통증없이 삽입되도록, 탄성 변형이 가능한 실리콘, 합성수지, 고무 중 어느 하나의 재질로 이루어지는 것이 바람직하다.The ear pad 10 according to the present invention is elastically close to the inner wall of the ear canal, and is preferably made of any one of silicone, synthetic resin, and rubber which can be elastically deformed so as to be inserted into the inner wall of the ear canal without pain.

이러한 구성에 의하여, 본 발명에 따른 이어패드(10)를 일 예로서 스피커(3)와 마이크(5)가 내장된 이어폰(1)에 장착하여 사용자의 외이도에 삽입하는 경우, 도 6에 도시된 바와 같이 삽입 헤드(21)가 외이도 내벽에 밀착함과 동시에, 각 트레드(31)는 삽입 헤드(21)의 반대방향으로 탄성 변형하며 삽입된다.By such a configuration, when the ear pad 10 according to the present invention is mounted on the earphone 1 with the speaker 3 and the microphone 5 as an example, and inserted into the ear canal of the user, as shown in FIG. As the insertion head 21 is in close contact with the inner ear canal wall, each tread 31 is inserted while being elastically deformed in the opposite direction of the insertion head 21.

한편, 한 쌍의 트레드(31)는 삽입 헤드(21)의 반대방향을 향할수록 외경이 점진적으로 증대되는 단면형상을 가짐에 따라, 각 트레드(31)가 삽입 헤드(21)의 반대방향으로 젖혀지며 외이도 내벽에 밀착된다.On the other hand, as the pair of treads 31 have a cross-sectional shape in which the outer diameter gradually increases as the direction toward the opposite direction of the insertion head 21, each tread 31 is bent in the opposite direction of the insertion head 21. The outer ear canal adheres to the inner wall.

따라서, 각 트레드(31)와 외이도 내벽 사이에 마찰력이 발생하게 되어, 이어패드(10)가 외력에 의해 쉽게 외이도로부터 이탈하지 않게 되며, 쾌적하고 안정적으로 착용할 수 있게 된다.Therefore, friction force is generated between each tread 31 and the inner ear canal wall, so that the ear pad 10 is not easily detached from the ear canal by the external force, and can be worn comfortably and stably.

또한, 각 트레드(31)에 의해 외이도 내벽이 차폐됨에 따라, 외부의 잡음이 외이도로 유입되는 것을 차단하게 된다.In addition, as the inner wall of the external auditory meatus is shielded by each tread 31, external noise is blocked from flowing into the external auditory meatus.

그리고, 최소한의 트레드(31)가 외이도 내벽에 밀착됨에 따라, 이어패드 몸체(11)의 관통공(13)을 통해 전달되는 소리의 증폭이 저하되는 것을 줄일 수 있게 된다.As the minimum tread 31 is in close contact with the inner ear canal wall, the amplification of the sound transmitted through the through hole 13 of the ear pad body 11 may be reduced.

또한, 한 쌍의 트레드(31)가 서로 다른 직경을 가짐에 따라, 사용자의 외이도의 크기에 관계없이 이어패드(10)를 간편하게 착용할 수 있게 되어, 사용자의 편의성을 향상시킬 수 있게 된다.In addition, as the pair of treads 31 have different diameters, the ear pads 10 can be easily worn regardless of the size of the ear canal of the user, thereby improving user convenience.

한편, 전술한 실시예에서는 스피커와 마이크가 내장된 이어폰에 본 발명에 따른 이어패드가 장착되는 것으로 설명하고 있지만 이에 한정되지 않으며, 본 발명에 따른 이어패드는 스피커가 내장된 이어폰, 유선형 이어마이크, 블루투스 헤드셋, wifi 헤드셋, 근거리 무선통신 헤드셋(NFC 헤드셋), binary CDMA 헤드셋 등에 장착될 수 있음을 밝혀둔다. On the other hand, in the above-described embodiment, the ear pad according to the present invention is described as being mounted on the earphone with a speaker and a microphone, but the present invention is not limited thereto, and the ear pad according to the present invention includes a earphone with a speaker, a wired ear microphone, Bluetooth headsets, wifi headsets, short-range wireless headsets (NFC headsets), binary CDMA headsets, etc.
