본 고안은 저음용 스피커에 관한 것으로, 특히 진동판외측에다 드로운콘(drone cone)을 설치해서 저음 특성을 향상시켜준 드로운콘일체형 저음용스피커에 관한 것이다.The present invention relates to a woofer speaker, and more particularly, to a drop cone integrated bass speaker having a drone cone installed outside the diaphragm to improve bass characteristics.
일반적으로 스피커는 전기신호를 음성신호로 변환시켜주는 장치로서, 특히 다이나믹형 스피커는 비교적 그구조가 간단하고 변환효율이 높을 뿐만 아니라 광범위한 음성재생대역을 통해 양호한 특성을 가지고 있어 가장 폭넓게 사용되고 있는바, 이러한 다이나믹형 스피커는 일반적으로 마그네트와 플레이트 및 센터폴로 구성된 자기회로를 통해 보이스코일에 연결된 진동판을 진동시켜 음성을 재생시켜주도록 되어 있다.In general, a speaker is a device that converts an electrical signal into a voice signal, and in particular, a dynamic speaker has a relatively simple structure, high conversion efficiency, and good characteristics through a wide range of voice reproduction bands. Such a dynamic speaker is generally designed to reproduce voice by vibrating a diaphragm connected to a voice coil through a magnetic circuit composed of a magnet, a plate, and a center pole.
한편, 저음용스피커는 저음재생대역을 넓혀주기 위해 진동판의 재질을 부드럽게 한다든지 또는 케비넷에 원통형덕트를 형성시켜 진동판의 콤플라이언스를 향상시켜주고, 덕트의 공진점과 스피커의 최저공진주파수에 의한 케비넷의 공진주파수까지 재생대역을 넓혀주므로서 저음특성을 향상시켜주고는 있었으나, 진동판의 재질변경으로 인해 진동판의 제조공정이 복잡하여 원가상승의 요인이 발생되고 있었을 뿐만 아니라 덕트내의 정재파의 발생으로 스피커의 출력 특성이 불량해지는 등의 문제점이 있었다. 이러한 문제점을 해결해주기 위하여 근래에는 스피커케비넷에다 보이스 코일이 없고, 진동계만 붙어 있는 일종의 더미우퍼(dummy woofer)를 설치해 놓은 드로운콘시스템(drone cone system)를 널리 채용하고있다.On the other hand, bass speakers improve the compliance of the diaphragm by softening the material of the diaphragm or by forming a cylindrical duct in the cabinet to widen the bass reproduction band, and improve the compliance of the cabinet by the resonance point of the duct and the lowest resonant frequency of the speaker. Although the resonant frequency was widened, the bass characteristics were improved, but the manufacturing process of the diaphragm was complicated by the material change of the diaphragm. There were problems such as poor properties. In order to solve this problem, recently, a drone cone system, which has a voice woofer in a speaker cabinet and has a kind of dummy woofer attached only to a vibrometer, is widely used.
그러나 이러한 종래의 드로운콘시스템은 제1도에 도시된 바와같이 케비넷의 일부에다 별도의 드로운콘을 부착시켜주고 있기 때문에 케비넷의 부피가 커지게 되고, 별도의 드로운콘을 제작하고 부착하는데 따른 제품의 원가상승의 요인으로 되고 있다.However, since the conventional draw cone system attaches a separate draw cone to a part of the cabinet as shown in FIG. 1, the volume of the cabinet becomes large, and a separate draw cone is manufactured and attached. As a result, the company's cost rises.
이에 본 고안은 상기와 같은 문제점을 해결해 주기 위해 인출된 것으로, 스피커프레임의 외주연을 연장형성시켜 여기에다 드로운콘을 실치해 놓음으로써, 이 드로운콘이 진동판과 역위상으로 진동해서 저음대역을 공진시켜줌으로서 저음특성이 향상되도록된 드로운코일체형 저음용스피커를 제공함에 그 목적이 있다.Therefore, the present invention was drawn to solve the above problems, by extending the outer circumference of the speaker frame and placing the draw cone on it, the draw cone vibrates in the reverse phase with the diaphragm to reduce the low band. It is an object of the present invention to provide a draw coil integrated low-speaker speaker, which is designed to improve resonance by resonating.
이하 본 고안의 구성 및 작용, 효과를 예시된 도면에 의거 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 자기회로부(1)상에 진동판(2)과 연결된 보이스코일(3)이 설치되고, 상기 자기회로부(1)의 상부플레이트(4)상에는 상기 진동판(2)이 지지되는 프레임(5)이 설치되면서 이 프레임(5)의 외측부에는 연장부(6)가 형성되고, 이 연장부(6)상에는 가스켓(7)을 매개로 드로운콘(8)이 설치된 구조로 되어 있다.According to the present invention, the voice coil 3 connected to the diaphragm 2 is installed on the magnetic circuit part 1, and the frame 5 on which the diaphragm 2 is supported on the upper plate 4 of the magnetic circuit part 1. The extension part 6 is formed in the outer part of this frame 5 in this installation, and the draw cone 8 is provided on the extension part 6 via the gasket 7. As shown in FIG.
미 설명부호 9는 스피커이다.Reference numeral 9 is a speaker.
상기와 같은 구조로 된 본 고안은, 케비넷(도면에 도시되지 않음)에 설치되게 되면 진동판(2)의 진동에 따라 드로운콘(8)이 상기 진동판(2)과 역위상으로 진동되면서 진동음의 저음영역을 공진시켜 줌으로써, 저음재생대역이 훨씬 넓어 지도록 되어있을 뿐만 아니라 종래에 드로운콘을 별도로 설치시켜 놓케 됨에 따른 여러가지 문제점들을 해소시켜 주도록 되어있다.The present invention has a structure as described above, when installed in the cabinet (not shown in the drawing), the draw cone (8) in accordance with the vibration of the diaphragm (2) vibrating in reverse phase with the diaphragm (2) of the vibration sound By resonating the bass region, the bass reproduction band is not only wider, but also solves various problems caused by the conventional draw cone separately installed.
한편 제2도는 본고안의 단면도로서, 프레임(5)의 외측에 연장부(6)가 형성되고 이 연장부(6)상에는 가스켓(7)을 매개로 드로운콘(7)이 설치되어 있는 것을 보여주고 있는데, 자기회로부(1)상에 설치된 보이스코일(3)이 인가되는 전류신호에 따라 상하로 구동되게되면, 그에 따라 진동판(2)이 진동되면서 음이 재생되게 된다. 여기서 스피커(9)가 케비넷에 부착되게 되었을때 스피커(9)와 케비넷사이에 밀폐된 공간이 형성되게 되어 진동판(2)이 상측으로 진동되는 순간에는 상기 드로운콘(8)이 하측으로 진동되게 되고, 상기 진동판(2)이 하측으로 진동되는 순간에는 상기 드로운콘(8)이 상측으로 진동되게 됨으로써 상기 드로운콘(8)에는 진동판(2)이 역위상공진음이 발생하게 된다.2 is a cross-sectional view of the present invention, showing that the extension portion 6 is formed on the outer side of the frame 5 and the draw cone 7 is provided on the extension portion 6 via the gasket 7. When the voice coil 3 installed on the magnetic circuit part 1 is driven up and down according to the applied current signal, the diaphragm 2 is vibrated accordingly to reproduce sound. Here, when the speaker 9 is attached to the cabinet, a sealed space is formed between the speaker 9 and the cabinet so that the draw cone 8 vibrates downward when the diaphragm 2 vibrates upward. When the diaphragm 2 is vibrated downward, the draw cone 8 is vibrated upward, so that the diaphragm 2 generates an antiphase resonant sound in the draw cone 8.
이때 드로운콘(8)은 진동판(2)의 저음보다 더욱 낮은 주파수로 공진되게 되어 스피커(9)이 저음재생대역을 한층 넓혀주게 된다.At this time, the draw cone 8 is resonated at a lower frequency than the bass of the diaphragm 2, so that the speaker 9 further widens the bass reproduction band.
이와같이 본 고안은 진동판(2)의 가장자리 바깥쪽에다 드로운콘(8)을 설치해 놓아 진동판(2)의 진동음보다 더욱 낮은 주파수를 방사시켜줌으로써 저음특성이 더욱향상되게 될 뿐만 아니라 스피커 케비넷의 크기가 소형화되고, 별도의 설치작업이 필요없이 제품의 제조원가를 낮출수 있는 효과가 있다.As such, the present invention places a drop cone 8 outside the edge of the diaphragm 2 to radiate a lower frequency than the vibration sound of the diaphragm 2 to further improve the bass characteristics, as well as the size of the speaker cabinet. It is miniaturized and has the effect of lowering the manufacturing cost of the product without the need for additional installation work.
