본 고안은 반발마그네트를 이용하여 자속의 누출을 감쇄시켜줄 수 있도록 된 리펄션(REPULSION) 스피커에 관한 것으로, 특히 상부플레이트와 실드케이스를 일체로 형성시켜주므로서 자속누출을 감쇄시켜줄 수 있도록 된 리펄션 스피커에 관한 것이다.The present invention relates to a repulsion speaker that can reduce the leakage of magnetic flux by using a repulsive magnet. In particular, the repulsion that can reduce the magnetic flux leakage by forming the upper plate and the shield case integrally It is about a speaker.

전기신호를 음성신호로 변환시켜주는 역할을 하는 스피커는 일반적으로 영구자석과 상하플레이트 및 센터폴로 구성된 자기회로를 통해 보이스코일을 구동시켜 줌으로써 보이스코일에 연결된 진동판을 진동시켜 음성을 재생시켜 주도록 되어 있는데, 이때 만일 상기 자기회로로부터 자속이 누출되게 되면 그 주위에 있는 전기 및 전자소자에 나쁜 영향을 끼칠 우려가 있고, 특히 텔레비젼이나 모니터등과 같이 자장을 이용하여 전자빔을 편향시켜 주도록 되어 있는 기기에 있어서는 스피커의 자기회로로부터 누출되는 자속으로 말미암아 화질이 저하되는 현상이 일어나게 된다.A speaker that converts an electric signal into a voice signal generally drives a voice coil through a magnetic circuit composed of a permanent magnet, an upper and lower plate, and a center pole to vibrate the diaphragm connected to the voice coil to reproduce voice. At this time, if the magnetic flux leaks from the magnetic circuit, it may adversely affect the electric and electronic devices around it. In particular, in a device that is used to deflect the electron beam by using a magnetic field such as a TV or a monitor. The magnetic flux leaking from the speaker's magnetic circuit causes the image quality to deteriorate.

따라서 종래에는 스피커의 자석으로서 고특성의 알루니코마그네트를 사용하여 자기회로를 형성시켜 주므로써 자속을 차폐시키거나 제1도와 같이 반발마그네트를 이용하여 자속의 누출을 감쇄시켜 주도록 함으로써 자기회로의 자속이 외부소자에 양향을 끼치지 않도록 하고 있었다.Therefore, in the related art, a magnetic circuit is formed by using aluminium magnet having high characteristics as a magnet of a speaker, thereby shielding the magnetic flux or reducing the magnetic flux leakage by using a repulsive magnet as shown in FIG. It did not affect the external device.

그러나 후자와 같이 반발마그네트를 이용하여 자속의 누출을 감쇄시켜주도록된 종래의 스피커는, 제1도에 도시된 바와 같이, 실드케이스의 일단을 상부 플레이트와 결합시켜주고 있었으나, 이는 마그네트 및 하부플레이트 두께의 변동에 따라 실드케이스의 금형을 별도로 제작하여야 할 뿐만아니라, 상부플레이트와 실드케이스의 결합부에서 자속이 누출되게된다는 문제점이 있었다.However, the conventional speaker designed to attenuate the leakage of magnetic flux by using a repulsive magnet as in the latter, as shown in Figure 1, was to combine one end of the shield case with the upper plate, which is the magnet and lower plate thickness According to the fluctuation of the mold of the shield case to be manufactured separately, there was a problem that the magnetic flux leaks from the coupling portion of the upper plate and the shield case.

이에 본 고안에서는 상기와 같은 종래의 문제점을 해결하여 마그네트 및 하부플레이트의 두께를 자유롭게 조절할 수 있을 뿐만아니라 실드케이스의 금형을 별도로 제작할 필요가 없도록 하부 플레이트의 상·하면에 페라이트마그네트와 반발마그네트를 각각 설치하고, 상기 페라이트마그네트의 상면에는 리펄션실드케이스를 설치하며, 상기 반발마그네트의 하면에는 뒷덮개를 설치하되 뒷덮개를 스크류우로 결합설치해 놓은 스피커를 제공하는데 그 목적이 있다.Therefore, the present invention solves the conventional problems as described above, so that the thickness of the magnet and the lower plate can be freely adjusted, and the ferrite magnet and the repulsive magnet are respectively formed on the upper and lower surfaces of the lower plate so that the mold of the shield case is not required to be manufactured separately. To install, and the upper surface of the ferrite magnet is installed a shield shield case, the lower surface of the repulsion magnet is provided with a rear cover but the rear cover is coupled to the screw installed to provide a speaker.

이하 본 고안의 구성 및 작용, 효과를 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 하부플레이트(1)의 상·하면에 페라이트마그네트(2)와 반발마그네트(2')를 각각 설치하고, 상기 페라마그네트(2)의 상면에는 상부플레이트(3)와 실드케이스(4)가 일체로 된 리펄션실드케이스(5)를 설치하는 한편, 상기 반발마그네트(2')의 하면에는 뒷덮개(6)를 설치하되 뒷덮개(6)를 스크류우(7)로 결합설치해 놓은 구조로 되어 있다.According to the present invention, the ferrite magnet 2 and the repulsive magnet 2 'are respectively provided on the upper and lower surfaces of the lower plate 1, and the upper plate 3 and the shield case 4 are provided on the upper surface of the ferramagnetic magnet 2, respectively. Is installed in the repulsion shield case (5), while the back cover (6) is installed on the lower surface of the repulsion magnet (2 '), but the rear cover (6) is coupled to the screw right (7) It is.

미설명부호 8은 결합부, 9는 자기회로부이다.Reference numeral 8 denotes a coupling portion, and 9 denotes a magnetic circuit portion.

상기와 같은 구조로 된 본 고안은 제2도에 도시된 바와 같이, 반발마그네트(2')를 이용하여 자속을 누출을 감쇄시켜 주는 스피커에 있어서, 하부플레이트(1)의 상면에 설치된 페라이트마그네트(2) 상면에 상부플레이트(3)와 실드케이스(4)를 일체로 형성시킨 리펄션실드케이스(5)를 결합 설치하여 상부플레이트(3)와 실드케이스(4)의 결합부(8)에서 자속이 누출되는 요인을 제거할 수 있게될 뿐만아니라, 페라이트마그네트(2) 및 하부플레이트(1)의 두께 변동에 관계없이 부품을 공용화할 수 있도록 한 것이다.The present invention having the structure as described above, as shown in Figure 2, in the speaker to reduce the magnetic flux leakage by using the repulsion magnet (2 '), the ferrite magnet (installed on the upper surface of the lower plate ( 2) a magnetic flux at the coupling portion 8 of the upper plate 3 and the shield case 4 by coupling and installing the reflex shield case 5 in which the upper plate 3 and the shield case 4 are integrally formed on the upper surface; Not only can this leak factor be eliminated, but also the parts can be shared, regardless of the thickness variation of the ferrite magnet 2 and the lower plate 1.

이를 좀더 상세히 설명하면, 상기 반발마그네트(2')의 하면에 뒷덮개(6)를 설치하되 뒷덮개(6)를 하부플레이트(1)의 하면 중앙부에서 스크류우(7)로 결합설치하여 하부플레이트(1)의 두께뿐만 아니라 페라이트마그네트(2) 및 반발마그네트(2')의 두께가 줄어든다하더라도 실드케이스(4)의 금형을 별도로 제작할 필요가 없도록 한 것으로서, 다시말해 자기회로부(9)의 두께에 변동이 생기면 상기 스크류우(7)를 조이거나 풀어 뒷덮개(6)를 반발마그네트(2')의 하면에다 결합 설치시킬 수 있도록 한 것이다To describe this in more detail, the rear cover 6 is installed on the bottom surface of the repulsion magnet 2 'but the rear cover 6 is coupled to the lower plate by installing the screw right 7 at the center of the bottom surface of the lower plate 1. Although not only the thickness of (1) but also the thicknesses of the ferrite magnets 2 and the repulsive magnets 2 'are reduced, it is not necessary to separately manufacture a mold of the shield case 4, that is, the thickness of the magnetic circuit part 9 is reduced. When the fluctuation occurs, the screw right (7) is tightened or loosened so that the rear cover (6) can be coupled to the lower surface of the repulsion magnet (2 ').

이와 같은 본 고안은 상부플레이트(3)와 실드케이스(4)를 일체로 형성시켜줌과 더불어 스크류우(7)로 뒷덮개(6)를 결합시켜줌으로써 페라이트마그네트(2)와 반발마그네트(2') 및 하부플레이트(1)등인 자기회로부(9)의 두께를 자유롭게 조절할 수 있도록 되고, 그에따라 음의 재생특성을 필요한 범위로 조정할수 있을 뿐만아니라 자기회로부(9)의 두께 변동에 따른 실드케이스(4)의 금형제작을 별도로 제작할 필요가 없는 효과가 있다.This invention devises the upper plate (3) and the shield case (4) integrally, as well as by combining the rear cover (6) with the screw (7) ferrite magnet (2) and repulsive magnet (2 ') And it is possible to freely adjust the thickness of the magnetic circuit portion (9), such as the lower plate (1), and accordingly can not only adjust the reproduction characteristics of the sound in the required range, but also the shield case (4) according to the variation of the thickness of the magnetic circuit portion (9) ), There is no need to make a separate mold production.
