본 고안은 스피커에 관한 것으로, 특히 스피커의 후단부에다 진동음분산판을 부착시켜 스피커재생음의 공명 및 찌그러짐 현상을 방지하도록 된 스피커에 관한 것이다.The present invention relates to a speaker, and more particularly to a speaker that is attached to the rear end of the speaker to prevent the resonance and distortion of the speaker reproduction sound by attaching a vibration sound distribution plate.
일반적으로, 스피커는 전기신호를 음성신호로 변환해 주는 장치인데, 특히 그중 다이나믹 스피커는 비교적 그 구조가 간단하고 변화효율이 높을 뿐만 아니라 광범위한 음성재생 대역을 통해 양호한 특성을 갖고 있는 것이기 때문에 널리 사용되고 있는바, 이는 영구자석과 플레이트 및 센서폴로 구성된 자기회로를 통해 보이스 코일을 구동시켜줌으로써 보이스코일에 연결된 진동판을 진동시켜 음성을 재생시켜주도륵 되어 있다.In general, a speaker is a device that converts an electrical signal into a voice signal, and in particular, a dynamic speaker is widely used because of its relatively simple structure, high change efficiency, and good characteristics through a wide range of voice reproduction bands. Bar, it is designed to reproduce the voice by vibrating the diaphragm connected to the voice coil by driving the voice coil through a magnetic circuit consisting of a permanent magnet, a plate and a sensor pole.
한편 진동판으로부터 음이 재생될때에는 진동판의 앞면과 뒷면 양쪽으로부터 음이 방사되게 되고, 이음은 각각의 위상이 반대인 관계로 앞면의 소리는 뒷면의 소리에 영항을 받아 강쇄된 효과가 나타나게 되면서 특히 파장이 긴 낮은 주파수에서는 더욱 심하게 나타나게 되는데, 이와같은 음의 간섭현상을 방지하기 위해서는 일반적으로 배플(baffle)을 설치하여 앞뒤의 음이 서로 간섭하지 않도록 하거나 밀폐형 캐비넷을 사용하여 뒷면에서 발생하는 소리를 모두 캐비넷속에 가둬 놓고 있다.On the other hand, when the sound is reproduced from the diaphragm, the sound is radiated from both the front and the back of the diaphragm, and the sound of the front side is influenced by the sound of the back side, so that the sound of the front side is influenced by the sound of the back side. This long, low frequency is more severe. To prevent such sound interference, a baffle is usually installed to prevent the sound of the front and rear from interfering with each other, or to use a closed cabinet to remove all the sound from the back. It's locked in a cabinet.
그런데, 이와 같은 종래의 스피커캐비넷에서는 내부에서 정재파가 발생하여 공명현상이 일어나게 됨으로써 스피커의 음압특성을 나쁘게 하고 있었다However, in such a conventional speaker cabinet, standing waves are generated inside and resonance occurs, thereby deteriorating sound pressure characteristics of the speaker.
한편 이를 방지하기 위해 종래에도 캐비넷내면에 여러 가지 흡음부재를 부착시켜 주고는 있었으나, 그 또한 제1도에서 볼 수 있는 바와 같이 진동음이 대부분 진동판의 후면과 캐비넷사이에서 직접반사되기 때문에 공명현상을 완전히 제거하지 못하고 있었다.On the other hand, in order to prevent this, in the past, various sound absorbing members were attached to the inner surface of the cabinet, but as can be seen in FIG. It could not be removed.
이에, 본 고안은 상기와 같은 문제점을 해결하기위하여, 스피커의 후단부에다 진동음분산판을 부착시켜 진동음의 공명현상이 방지되도록 된 스피커를 제공하는데 그 목적이 있다.In order to solve the above problems, the present invention has a purpose to provide a speaker that is attached to the rear end of the speaker to the vibration sound dispersion plate to prevent resonance of the vibration sound.
이하 본 고안의 구성 및 작용, 효과를 예시된 도면을 통하여 상세히 설명한다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the illustrated drawings.
본 고안은 캐비넷(1)의 전면판(2)에 스피커(3)가 설치되면서 상기 스피커(3)의 후단부(4)에 진동음분산판(5)이 설치되는 구조로 되어 있다.The present invention has a structure in which the vibration sound distribution plate 5 is installed on the rear end portion 4 of the speaker 3 while the speaker 3 is installed on the front plate 2 of the cabinet 1.
미 설명부호 6은 진동판이다.Reference numeral 6 is a diaphragm.
상기와 같은 구조로 된 본고안은 진동판(6)뒷쪽으로 방사되는 재생음이 진동음분산판(5)에 의해 1차로 반사 되면서 캐비넷(1)의 간면으로 분산 흡수되어 소멸되게 된다.In the present invention having the structure as described above, the reproduction sound radiated to the rear of the diaphragm 6 is primarily reflected by the vibration sound distribution plate 5, and is dispersed and absorbed by the liver surface of the cabinet 1 to be extinguished.
한편, 제2도는 본 고안에 따른 스피커의 단면도로서, 스피커(3)의 후단부(4)에 진동음분산판(5)이 설치되어 있는 것을 보여주는 것인데, 진동판(6)으로부터 방사되는 진동음은 도면에서 점선으로 표시해주고 있는 바와 같이 진동음분산판(5)에서 1차로 반사되면서 캐비넷(1)의 각면으로 분산되게 되고, 이때 분산되는 진동음은 흡음재질로된 캐비넷(1)의 각면에 흡수되면서 소멸되게 된다.On the other hand, Figure 2 is a cross-sectional view of the speaker according to the present invention, showing that the vibration sound distribution plate 5 is installed on the rear end portion 4 of the speaker 3, the vibration sound radiated from the vibration plate 6 is As indicated by the dotted line, the vibration sound distribution plate 5 is first reflected while being distributed to each side of the cabinet 1, and the dispersed vibration sound is absorbed by each side of the cabinet 1 made of sound-absorbing material to be extinguished.
또한 제3도는 본 고안에 따른 진동음분산판(5)을 보여주는 것인데, 그 형상이 절두원추형으로 되어 있어 진동음이 진동음분산판(5)의 측면에 의해 반사되면서 분산 되도록 되어 있다.In addition, Figure 3 shows the vibration sound distribution plate 5 according to the present invention, the shape is a truncated cone shape so that the vibration sound is reflected while being reflected by the side of the vibration sound distribution plate (5).
상기와 같이 본고안은 스피커(3)의 후단부(4)에 진동음분산판(5)을 부착시켜 놓아 캐비넷(1)의 내부로 방사 되는 진동음이 분산, 소멸되게 됨으로써 재생음의 공명과 찌그러짐 현상이 방지되게 되고 스피커의 출력음압 특성을 향상시켜 주는 효과가 있다.As described above, the vibration sound distribution plate 5 is attached to the rear end 4 of the speaker 3 so that the vibration sound emitted into the cabinet 1 is dispersed and dissipated, thereby resonating and crushing the reproduction sound. It is prevented and has the effect of improving the output sound pressure characteristics of the speaker.
