본 고안은 스피커장치에 관한 것으로서, 특히 두 종류의 저음재생구조를 동시에 사용하여 보다 넓은 주파수대역에서 큰 출력음압을 나타내는 저음재생용 스피커장치에 관한 것이다.The present invention relates to a speaker device, and more particularly, to a speaker device for low sound reproduction, which exhibits a large output sound pressure in a wider frequency band by simultaneously using two types of low sound reproduction structures.
고충실도재생(Hi-Fi)이 비교적 힘든 종 저음재생을 위하여 다양한 스피커시스템이 제안되어 왔으며, 그 중에서도 2중공간을 이용한 체적비방식과 위상반대방사음을 이용한 베이스리플럭스(Base Refllex)방식이 널리 이용되고 있다.Various loudspeaker systems have been proposed for high-fidelity reproduction (Hi-Fi), which is relatively difficult to reproduce, and among them, the volume ratio method using double space and the bass refllex method using phase anti-radiation sound are widely used. It is used.
전자의 경우를 제1도를 참조하여 설명하면, 내 외부를 상호연통시키는 덕트(5)가 일측벽에 형성된 스피커박스(1)는, 격벽(6)에 의해 2개이 방 즉 덕트(5)를 통하여 외부와 연통되는 개방공간부(4)와 그렇지 아니한 밀폐공간부(3)로 구분되며, 격벽(6)의 중앙영력에는 개방공간부(4)를 향하여 스피커유니트(2)가 고정설치되어 있다. 스피커유니트(2)는 후방의 마그네트와(전방의 자동판등으로 구성되는 것으로서, 격벽(6)의 중앙영역은 이 진동판 외연에 맞추어 적절히 절취되어 있다. 밀폐공간부(3)는 대역통과필터(Band Pass Filter) 역할을 하는 것으로서, 고음주파수성분을 감쇠시키고 저음주파수분만을 재생시킨 후 덕트(5)를 통해 외부공간으로 방사한다.The former case will be described with reference to FIG. 1. In the speaker box 1 having a duct 5 communicating with the inside and the outside on one side wall, two partitions 6 form a room, that is, the duct 5. It is divided into an open space portion (4) and a non-closed space portion (3) which communicates with the outside through, and the speaker unit (2) is fixedly installed toward the open space portion (4) in the central force of the partition (6). . The speaker unit 2 is composed of a magnet on the rear side (an automatic plate of the front side, etc., and the center region of the partition wall 6 is appropriately cut out in accordance with the outer periphery of the diaphragm. Band Pass Filter), which attenuates high frequency components and reproduces only low frequency components, and radiates to the outer space through the duct (5).
이 저음재생시스템에서는 밀폐공간부(3)에 대한 개방공간부(4)의 체적비에 의해 방사되는 저음의 특성이 정해지는데, 체적비가 작아질수록 주파수특성대역은 좁아지는 반면 그곳에서의 출력음압은 커지고, 반대로 체적비가 커지면 주파수특성대역은 넓어지나 그 곳에서의 음압은 감소하게 된다. 따라서 넓은 특성대역과 합께 큰 음압특성을 얻는 것은 불가능하고 어느 정도 두 특성이 적당히 충족되는 곳에서 만족할 수 밖에 없었다.In this bass reproducing system, the characteristics of the bass radiated by the volume ratio of the open space part 4 to the closed space part 3 are determined. As the volume ratio becomes smaller, the frequency characteristic band becomes narrower, while the output sound pressure therein On the contrary, as the volume ratio increases, the frequency band becomes wider, but the sound pressure therein decreases. Therefore, it is impossible to obtain a large sound pressure characteristic in combination with a wide characteristic band, and it has to be satisfied where both characteristics are satisfactorily met.
제2도는 공지의 위상반전캐비넷 속칭 베이스리플렉스방식을 도시한 것으로서, 스피커박스(1)의 뒷판으로 방사된 저음의 일부를 위상반대로 하여 스피커유니트(2)의 전동판 전면에서 방사되는 음파와 같은 위상으로 만들어 저음특성을 개선한다.FIG. 2 shows a known phase inversion cabinet, known as a bass reflex method, in which phases such as sound waves radiated from the front of the driving plate of the speaker unit 2 are made by inverting a part of the bass radiated to the rear panel of the speaker box 1 in phase. Improve the bass characteristics.
이를 위해 스피커박스(1)의 일 내측면에 스피커유니트(2)가 외부를 향하여 부착되고 적절한 위치에 덕트(5)가 마련된 구조를 취하고 있다. 그러나 이 경우 역시, 소정범위의 주파수대역에서만 큰 음압을 얻을 수 있은 뿐 넓은 대역 전반에 걸쳐 큰음압특성을 갖는 저음재생은 불가능하다.To this end, the speaker unit 2 is attached to one inner surface of the speaker box 1 to the outside and has a structure in which the duct 5 is provided at an appropriate position. However, in this case as well, a large sound pressure can be obtained only in a frequency band of a predetermined range, and low sound reproduction having a large sound pressure characteristic over a wide band is impossible.
따라서, 본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 사익 두 방식을 결합하여 상호 보완케함으로써 넓은 대역에 걸쳐 큰 출력음압이 발생가능한 저음재생용스피커장치를 제공하는 것을 목적으로 한다.Accordingly, the present invention has been made to solve the above problems, it is an object of the present invention to provide a speaker device for low sound reproduction that can generate a large output sound pressure over a wide band by combining the two wing method.
전술한 목적을 달성하기 위하여 본 고안은, 마그네트와 진동판등으로 이루어지는 스피커유니트와 이 스피커유니트를 수납지지하기 위한 스피커박스를 구비한 스피커장치에 있어서,In order to achieve the above object, the present invention is a speaker unit comprising a speaker unit consisting of a magnet and a diaphragm and the like and a speaker box for housing and holding the speaker unit,
상기 스피커박스의 일측벽에 마련되어 상기 스피커박스의 내 외부를 상호연통시키는 덕트와, 상기 스피커박스를 상기 스피커유니트와 덕트를 포함한 개방공간부 및 그렇지 아니한 밀폐공간부로 구획하는 격벽 및 상기 개방공간부를 향하여 상기 격벽에 고정설치되는 추가의 스피커유니트를 포함하는 것을 특징으로 하는 스피커장치를 제공한다.A duct provided on one side wall of the speaker box to communicate the inside and outside of the speaker box, the partition wall partitioning the speaker box into an open space portion including the speaker unit and the duct and an unsealed space portion, and the open space portion; It provides a speaker device comprising an additional speaker unit fixed to the partition wall.
이하에서 첨부한 도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제3도는 본 고안의 일 실시예에 따른 스피커장치의 구성도이다. 본 스피커장치는 외형상 제1도에 도시한 스피커시스템의 개방공간부 (4) 내측벽에 추가의 스피커유니트(2')를 외부를 향하여 부착한 간단한 구조를 취하고 있으므로 서두에서 언급한 내용과 중복되는 부분은 설명을 생략한다.3 is a block diagram of a speaker device according to an embodiment of the present invention. This speaker device has a simple structure in which an additional speaker unit 2 'is attached to the outside on the inner wall of the open space part 4 of the speaker system shown in FIG. The description will be omitted.
본 스피커장치의 원리는, 전체적으로 보면 전술한 체적비방식을 유지하면서 부분적으로(개방공간부를 기준으로)보면 베이스리플렉스방식을 취하고 있다는 점이다. 따라서 체적비방식(제1도 참조)으로부터 낮은 제1주파수대역에서 큰 음압을 갖는 저음재생력을 확보함과 동시에 베이스리플렉스방식(제2도 참조)으로부터 보다 높은 제2주파수대역에서 큰 음압을 갖는 저음재생력을 확보함으로써, 보다 넓은 제1 및 제2주파수대역에 걸쳐 높은 음압특성을 나타낼 수 있는 것이다.The principle of the present speaker device is that, in general, the bass reflex method is taken in part (based on the open space) while maintaining the above-described volume ratio method. Therefore, it is possible to secure a low sound reproducing power with a high sound pressure in the low first frequency band from the volume ratio method (see FIG. 1) and at the same time, a low sound reproducing power with a high sound pressure in a higher second frequency band from the base reflex method (see FIG. By securing, it is possible to exhibit high sound pressure characteristics over a wider first and second frequency bands.
이해를 돕기 위하여 주파수대역에 대한 출력음압의 변화를 제5도로 도시하였다. 참조부호 b와 c는 각각 체적비방식 및 베이스리플렉스방식에 의한 음압특성을 나타낸다. 도시된바와 같이 본 고안에 따른 스피커장치의 음압특성 (a)는, 체적비방식에 기인한 제1주파수대역(Ⅰ)에서의 높은 음압특성과 베이스리플렉스방식에 기인한 제2주파수대역(Ⅱ)에서의 높은 응압특성이 그대로 유지되어, 보다 넓은 저음 주파수대역에 걸쳐 높은 음압특성을 나타내고 있다.For the sake of understanding, the change in the output sound pressure over the frequency band is shown in FIG. Reference numerals b and c denote sound pressure characteristics by the volume ratio method and the bass reflex method, respectively. As shown, the sound pressure characteristic (a) of the speaker device according to the present invention is the high sound pressure characteristic in the first frequency band (I) due to the volume ratio method and in the second frequency band (II) due to the bass reflex method. The high pressure-response characteristic of is maintained as it is, showing a high sound pressure characteristic over a wider low frequency band.
한편 추가의 스피커유니트(2') 및 덕트(5)의 위치와 관련하여 제4도와 같은 다른 실시예도 가능함은 물론이다.Of course, other embodiments, such as FIG. 4, are also possible with regard to the location of the additional speaker unit 2 'and the duct 5.
이상 설명한 바와 같이 본 고안에 따른 저음재생용 스피커장치는, 보다 넓은 저음주파수대역에 걸쳐 큰 출력음압을 나타낸다.As described above, the speaker device for bass reproduction according to the present invention exhibits a large output sound pressure over a wider bass frequency band.
