본 고안은 이중 바플 스피커에 관한 것으로, 특히 보조바플을 형성하여 바플의 후면에 위치시킴으로써 바플에 의한 공진을 없애고 이상음을 방지토록 한 이중 바플 스피커에 관한 것이다.The present invention relates to a double baffle speaker, and more particularly, to a double baffle speaker which forms an auxiliary baffle and is located at the rear of the baffle to eliminate resonance caused by the baffle and prevent abnormal sound.
종래기술에 의한 바플 스피커는 제1도에 도시된 바와 같이 스피커(10)와, 상기 스피커(10) 전면 양쪽단부에 결착되는 바플(11)과, 상기 각각의 바플(11)끝단과 결착되고 스피커(10)을 감싸는 케이스(12)와 상기 하측 바플(11')에 관통되어 결착되는 덕트(13)로 구성된다.The baffle speaker according to the prior art has a speaker 10, a baffle 11 that is fastened to both ends of the front surface of the speaker 10, and the ends of each baffle 11 as shown in FIG. It consists of a case 12 surrounding the 10 and a duct 13 penetrating through the lower baffle 11 '.
상기와 같이 구성된 스피커가 가동되면, 스피커(10)의 전면과 후면으로 음이 방사된다. 후면으로 방사된 음은 케이스(12)내에서 간섭되어 덕트(13)를 통해 전면으로 빠져 나가게 된다.When the speaker configured as described above is operated, sound is radiated to the front and rear of the speaker 10. The sound radiated to the back is interfered in the case 12 and exits to the front through the duct 13.
그러나, 후면으로 방사된 음은 케이스에 부딪히고 위상 반전되어 바플에 전달되므로써 이상음이 발생케 되고, 위상 반전된 음은 덕트를 통해 전면으로 방사되지만 스피커 전면으로 방사된 음과 동일한 축으로 전달되지 못할 뿐만 아니라 케이스 내부에 정재파가 남게 되어 특정주파수에서 이상음을 발생시키는 문제점이 있다.However, the sound radiated to the rear side hits the case and is phase-inverted and transferred to the baffle, causing the abnormal sound to be emitted. Not only that, there is a problem in that a standing wave remains inside the case to generate an abnormal sound at a specific frequency.
본 고안은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 바플 후면에 일정간격을 두고 보조바플을 형성하여 케이스에 부딪혀 위상 반전되는 음이 직접 바플에 부딪히지 않게 하고 위상 반전된 음이 스피커 전면으로 방사된 음과 동일한 축으로 방사되게 하여 이상음을 방지하고 저음감을 더욱 향상시킬 수 있는 이중 바플 스피커를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, by forming an auxiliary baffle at a certain interval on the back of the baffle, so that the sound of the phase inversion due to the case does not directly hit the baffle and radiates the phase inverted sound to the front of the speaker. It is an object of the present invention to provide a double baffle speaker that can be radiated on the same axis as the sound, thereby preventing abnormal sound and further improving bass.
상기와 같은 목적을 달성하기 위한 본 고안에 의한 이중 바플 스피커는 스피커와, 상기 스피커를 외부에서 감싸는 케이스와, 일단이 스피커 중앙부의 내측과 결착되고 타단이 스피커의 후면과 결착되어 케이스 내부공간을 양분하는 지지대와, 상기 스피커의 양쪽 끝면부에 결착되는 보조바플과, 상기 보조바플과 홀이 형성되도록 마주보게 위치된 바플로 구성되어 음이 후방으로 방사되면 케이스에 부딪히게 되고 케이스에 부딪히는 순간 음이 위상반전되어 홀을 빠져나가면서 스피커 전방으로 방사되는 정상적인 음과 동일한 위상이 되는 것을 특징으로 한다.Dual baffle speaker according to the present invention for achieving the above object is a speaker, the case surrounding the speaker from the outside, one end is bound to the inside of the speaker central portion and the other end is bound to the rear of the speaker to divide the internal space of the case And a sub baffle that is fastened to both ends of the speaker, and a baffle positioned to face the sub baffle and the hole, so that when the sound is radiated backward, the sound hits the case and the sound hits the case. It is characterized by being in phase with the normal sound radiated to the front of the speaker while the phase is reversed and exits the hole.
이하, 본 고안에 의한 이중 바플 스피커의 실시예를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of a double baffle speaker according to the present invention will be described in detail with reference to the accompanying drawings.
본 고안에 의한 이중 바플 스피커는 제2도 및 제3도에 도시된 바와 같이 스피커(20)와, 상기 스피커(20)전면 양쪽단부에 결착되어 전면으로 방사되는 음을 차단하는 보조바플(21)과, 상기 각각의 보조바플(21)과 홀이 형성되도록 일정간격을 두고 위치되는 바플(22)과, 상기 각각의 바플(22)의 끝단과 결착되고 스피커(20)를 외부에서 감싸는 케이스(23)와, 상기 케이스(23) 중앙부 내측과 일단이 결착되고 타단은 스피커(20)의 후면과 결착되는 지지대(24)로 구성된다.Dual baffle speaker according to the present invention is the secondary baffle (21) to block the sound radiated to the front by being coupled to both ends of the speaker 20, the front surface of the speaker 20, as shown in FIG. And a baffle 22 positioned at a predetermined interval so that each of the auxiliary baffles 21 and holes is formed, and a case 23 which is bound to an end of each of the baffles 22 and surrounds the speaker 20 from the outside. ), And the supporter 24 is coupled to the inner side and one end of the center of the case 23 and the other end thereof to the rear side of the speaker 20.
상기 보조바플(21)은 2단으로 절곡 형성되어 있다. 1단(21')은 케이스(23)의 내측을 향하고, 2단(21)은 바플(22)의 후면에 위치되고 단부가 케이스(23)와 일정 간격으로 유지되어 케이스(23)로부터 위상 반전되는 음이 보조바플(21)에 부딪히고 타고 넘는 음은 바플(22)과 보조바플(21)사이의 홀을 통과한다.The auxiliary baffle 21 is bent in two stages. The first stage 21 'faces the inside of the case 23, the second stage 21 is located at the rear of the baffle 22, and the ends are held at a predetermined distance from the case 23, thereby reversing the phase from the case 23. The sound that hits the secondary baffle 21 and passes over the sound passes through the hole between the baffle 22 and the auxiliary baffle 21.
상기 케이스(20)의 내면, 바플(22)의 내면 및 보조바플(21)의 표면에 흡음재(25)가 각각 부착되어 케이스(23)와 바플(22)과 보조바플(21)에 부딪혀 발생되는 이상음이 방지된다.The sound absorbing material 25 is attached to the inner surface of the case 20, the inner surface of the baffle 22, and the surface of the auxiliary baffle 21, respectively, and is caused by colliding with the case 23, the baffle 22, and the auxiliary baffle 21. Abnormal sounds are prevented.
상기와 같이 구성된 본 고안에 의한 이중 바플 스피커의 작용효과를 설명하면 다음과 같다.Referring to the effect of the double baffle speaker according to the present invention configured as described above are as follows.
스피커가 동작되면 스피커(20)의 전면과 후면으로 음이 방사된다. 스피커(20)후면으로 방사되는 음은 케이스(23)에 부딪혀 위상 반전되어 양쪽에 있는 보조바플(21)에 부딪히게 된다. 부딪힌 음은 흡음재(25)에 흡입되고 반사된 음은 보조바플(21)을 넘어 바플(22)과 보조바플(21) 사이의 홀을 통과하여 전면으로 방사되는 음과 동일축 상으로 방사된다. (도면 제3도 참조)When the speaker is operated, sound is radiated to the front and rear of the speaker 20. The sound radiated to the rear surface of the speaker 20 impinges on the case 23 and is reversed in phase to impinge on the auxiliary baffles 21 on both sides. The sound hit is absorbed by the sound absorbing material 25 and the reflected sound is radiated on the same axis as the sound radiated to the front surface through the hole between the baffle 22 and the auxiliary baffle 21 beyond the auxiliary baffle 21. (See Fig. 3)
이와 같이 본 고안에 의한 이중 바플 스피커는 바플 후면에 각각의 보조바플을 형성함으로써 위상 반전된 음이 바플에 직접 전달되지 않을 뿐만 아니라 스피커 전면으로 방사된 음과 동일한 축으로 방사되므로써 공진에 의한 이상음과 정재파로 인한 이상음을 방지하고 저음감을 더욱 향상시킬 수 있는 이점이 있다.As described above, the double baffle speaker according to the present invention forms an auxiliary baffle on the back of the baffle so that not only the phase inverted sound is directly transmitted to the baffle, but also is radiated on the same axis as the sound radiated to the front of the speaker, thereby causing abnormal sounds due to resonance There is an advantage that can prevent abnormal sounds due to standing waves and further improve the bass sound.
