본 고안은 멀티웨이스피커시스템의 구조에 관한 것으로, 특히 위상반전형의 저음용스피커(woofer)의 구조를 개량시킨 멀티웨이스피커 시스템에 관한 것이다.The present invention relates to a structure of a multi-way speaker system, and more particularly, to a multi-way speaker system in which a structure of a phase inverted low-woofer speaker is improved.

음향기기의 발달과 더불어 스피커도 각 음역의 재생을 담당하는 고음용(tweeter), 중음용(squaker), 저음용(woofer)의 스피커를 캐비넷에 함께 내장시킨 이른바 멀티웨이스피커시스템이 많이 보급되어져 있다.Along with the development of sound equipment, so-called multi-way speaker systems, in which a speaker, a tweeter, a squaker, and a woofer, which are responsible for reproducing each sound range, are incorporated in a cabinet, are widely distributed. .

이러한 스피커는 일반적으로 직접방사형의 다이나믹형이 주종을 이루고, 근래에는 진동판의 진동에 의하여 복사음과 진동암이 소멸하는 것을 막아주어 스피커의 저음을 보다 강화시킨 위상반전형스피커도 개발되어져있다.In general, such a speaker is mainly composed of a direct radiation type dynamic type, and in recent years, a phase inverted speaker has been developed to further enhance the bass of the speaker by preventing radiation and vibration from extinction due to vibration of the diaphragm.

한편, 종래의 멀티웨이스피커시스템은 제1도에서 보는 바와 같이 앞면을 향해 스피커의 진동판이 노출되어진 직접 방사형태를 많이 취하고 있는데, 스피커가 진동판과 자기 회로부 및 프레임으로 구성되어진 관계로 프레임에 의해서 진동판의 음압의 변화가 방해를 받는 점도 고려되어져야 한다.On the other hand, the conventional multi-way speaker system takes a lot of direct radiation form in which the diaphragm of the speaker is exposed toward the front as shown in Figure 1, the diaphragm by the frame because the speaker is composed of the diaphragm, the magnetic circuit portion and the frame. Consideration should be given to the disturbance of the sound pressure change.

즉, 프레임이 설치된 스피커의 뒷면은 캐비넷 내부에 내장되고, 진동판의 더스트캡 부분은 밖으로 노출되어진 상태로 설치되므로서 진동판의 진동시 스피커뒷쪽으로 생기는 진동음은 이 프레임에 의해 방해를 받게되고, 이 음이 다시 캐비넷 내벽에 반사되어 청취자에게 들릴때에는 처음의 음압보다도 훨씬 감소된, 이른바 재생음이 나쁜 결과를 초래하고, 이는 음악애호가들의 취향에도 역행되는 문제점으로 개선의 여지가 많았던 것이다.That is, the back of the speaker with the frame is built in the cabinet, the dust cap portion of the diaphragm is installed to the outside exposed state, the vibration sound generated behind the speaker during the vibration of the diaphragm is hindered by this frame. When reflected back to the cabinet wall and heard by the listener, the so-called reproducing sound, which is much lower than the original sound pressure, has a bad result, which is contrary to the taste of music lovers.

이에 본 고안에서는 특히 저음용스피커(woofer)를 원래 위치와 반대로, 즉 뒤집어 배치한 상태로 하되, 캐비넷내의 진동음이 반전되어 나올 수 있도록 캐비넷 전면에 덕트(duct)와 관통호울(hole)을 형성시킨 것이다.In the present invention, in particular, the speaker for the lower (woofer) in the opposite position, that is, the state is placed upside down, the duct and the through hole (hole) formed on the front of the cabinet so that the vibration sound in the cabinet can be reversed will be.

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

본 고안은 캐비넷내의 저음용스퍼커(woofer, 1)를 자기회로부(2)가 외부를 향하도록 설치하고, 상기 스피커(1)의 프레임(3)과 프레임(3) 사이에는 캐비넷 전면(4)으로 관통되는 음반사용의 덕트(duct, 5)를 설치하는 한편, 캐비넷전면(4)의 스피커둘레에는 위상반전용덕트(6)가 형성되며, 상기 저음용스피커(1)와 중음용스피커(7)사이에는 가로막(8)을 설치시킨 구조로 된 멀티웨이스피커시스템이다.The present invention is to install a low-frequency spur (woofer, 1) in the cabinet so that the magnetic circuit portion 2 facing outwards, between the frame 3 and the frame 3 of the speaker 1 to the front cabinet (4) A duct 6 for a phase change is formed on the speaker circumference of the cabinet front 4 while a duct 5 for penetrating recordings is provided, and the low sound speaker 1 and the middle sound speaker 7 are provided. It is a multi-way speaker system having a structure in which a diaphragm 8 is installed therebetween.

도면중 미설명 부호 9는 캐비넷이다.In the drawing, reference numeral 9 denotes a cabinet.

제2도는 본 고안에 따른 멀티웨이스피커시스템의 정면도로서, 스피커이면의 진동음은 스피커프레임(3) 사이의 덕트(5)로 직접방사되고, 스피커 전면의 진동에 의한 음파는 캐비넷 내벽에 부딪혀 반사되어 위상반전용덕트(6)로 방사되어진다.2 is a front view of the multi-way speaker system according to the present invention, the vibration sound of the rear surface of the speaker is directly radiated into the duct 5 between the speaker frame (3), the sound waves due to the vibration of the front of the speaker hit the inner wall of the cabinet is reflected The phase reflection duct 6 is radiated.

따라서 종래의 스피커시스템에서처럼 스피커이면의 반사음이 무시되는 결점을 보완하여 오히려 스피커 이면음을 직접 방사에 의한 음압변화로 청취하고, 스피커 전면의 진동음은 캐비넷 벽에서 반사되어 덕트(6)를 통해 방사되므로 음의 재생효율이 극대화되며, 특히 진동판의 진동에 의한 음압변화가 위상에 의해 서로 상쇄되어 진동음이 적어지는 단점을 해소시킬 수가 있다.Therefore, as in the conventional speaker system, it compensates for the drawback that the reflected sound on the rear side of the speaker is ignored and rather listens to the sound pressure change by direct radiation, and the vibration sound on the front of the speaker is reflected on the cabinet wall and radiated through the duct 6 The sound reproduction efficiency is maximized, and in particular, the sound pressure change due to the vibration of the diaphragm cancels each other by the phase, thereby eliminating the disadvantage of less vibration sound.

한편, 저음용스피커의 진동폭은 타음역의 스피커작동에 방해를 줄만큼 크므로 저음용스피커(1)와 중음용스피커(7) 사이에 가로막을 설치하여 음의 간섭에 의한 재생음 효율의 저하를 막도록 한다.On the other hand, the vibration width of the low-end loudspeaker is large enough to obstruct the operation of the speaker in the other sound region, so that a diaphragm is installed between the low-peak speaker 1 and the mid-range speaker 7 to prevent the degradation of the reproducing sound efficiency due to sound interference. To do that.

상기와 같은 본 고안에 따른 스피커시스템을 사용하므로서 저음에서의 위상반전에 의한 탁월한 재생음의 실현이 가능하고, 특히 타음역의 스피커에 방해를 주지않아 스피커의 음재생 역할을 극대화시킬 수 있다.By using the speaker system according to the present invention as described above it is possible to realize the excellent reproduction sound by the phase inversion in the bass, and in particular, it is possible to maximize the role of sound reproduction of the speaker without disturbing the speaker of the other sound range.
