본 고안은 텔레비젼 수상기의 대자(帶磁)방지용 스피커에 관한 것으로, 특히 스피커의 후면에 페라이트(Ferrite)판을 부착하여 스피커에서 발생되는 자속(Flux)을 흡수 하므로서 자기로 인하여 발생되는 수상관내의 대자 현상을 방지하게 되는 것이다.The present invention relates to the anti-magnetism speaker of a television receiver, and in particular, a ferrite plate is attached to the rear of the speaker to absorb magnetic flux generated from the speaker, thereby causing magnetism in the water pipe caused by magnetism. It will prevent the phenomenon.
최근에는 텔레비젼 수상기등의 디자인이 다양해지고 기구적 구조가 소형화되는 경향에 의하여 수상관에 인접하여 스피커가 위치하게 됨에 따라, 스피커에서 발생되는 자속(Flux)에 의해 수상관내의 새도우마스크(Shadow Mask)가 대자되어 전자비임이 간섭을 받으므로서 전자비임의 진행 방향이 바뀌어 화면에 색의 얼룩이 생기는 문제점이 발생하였다.Recently, as the speaker is positioned adjacent to the receiving tube due to the tendency of various designs of the television receiver and the mechanical structure, the shadow mask in the receiving tube is caused by the flux generated from the speaker. Due to the interference of the electron beam, the moving direction of the electron beam is changed, causing a problem of color unevenness on the screen.
종래에는 상기와 같은 문제점을 해결하기 위하여 스피커 본체 내면에 원통형의 페라이트 코어를 삽입하여 스피커를 제작하여 수상기에 부착하므로서, 스피커 측면 방향으로 발생되는 자속은 흡수할 수 있으나, 스피커의 전, 후면의 방향으로 발생되는 자속은 흡수되지 않아 전술한 바와같은 문제점이 발생하였다.Conventionally, in order to solve the above problems, by inserting a cylindrical ferrite core into the inner surface of the speaker body to produce a speaker attached to the receiver, the magnetic flux generated in the speaker side direction can be absorbed, but the direction of the front and rear of the speaker The generated magnetic flux is not absorbed, resulting in the problems described above.
본 고안은 상기와 같은 문제점을 해결하기 위하여 스피커 본체 후면에 페라이트판을 부착하여 스피커의 전, 후면 방향으로 발생하는 자력을 흡수하므로서, 수상관의 양호한 색순도를 유지할 수 있는 텔레비젼 수상기의 대자방지용 스피커를 제공하고져 함에 고안의 목적이 있는 것이다.The present invention to solve the above problems by attaching a ferrite plate on the rear of the speaker body to absorb the magnetic force generated in the front and rear direction of the speaker, to prevent the anti-magnetism speaker of the television receiver that can maintain a good color purity of the water pipe It is the purpose of design to provide.
이하, 본 고안의 일실시예를 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
스피커 본체(2)내면에 원통형의 페라이트코어가(7) 삽입되어 부착된 스피커(1)에 있어서, 상기 스피커 본체(2)의 후면(3)에 삽지구(3a)(3b)를 일체로 형성하여 얇은 판으로 된 페라이트판(4)을 삽입하여 고정되게 장착함을 특징으로 하는 텔레비젼 수상기의 대자방지용 스피커이다.In the speaker 1 having a cylindrical ferrite core (7) inserted into an inner surface of the speaker body (2), the insertion holes (3a) and (3b) are integrally formed on the rear surface (3) of the speaker body (2). It is a speaker for preventing antimagnetism of a television receiver, characterized in that a thin plate of ferrite plate (4) is inserted and fixed.
또한, 첨부도면 제 3 도는 본 고안의 다른 실시예로서, 페라이트판(4)을 양면에 접착층을 형성한 접착판(4')을 이용하여 스피커 본체(2)의 후면(3)에 부착시킨 것이다.3 is a view illustrating another example of the present invention, in which a ferrite plate 4 is attached to the rear surface 3 of the speaker main body 2 using an adhesive plate 4 'having an adhesive layer formed on both surfaces thereof. .
이와같이 구성된 본 고안은 스피커(1)의 축 방향으로 발생되는 자속은 코일(6)과 본체(2) 사이에 끼워진 원통형의 페라이트코어(7)에 의해 흡수하여 차단하고, 전, 후면 방향으로 발생되는 자속은 본 고안의 스피커본체(2)의 후면(3)에 부착되는 페라이트판(4)에 의해 흡수하므로 스피커(1)주위에 설치된 다른 부속은 물론, 텔레비젼 수상관의 전자비임의 진행방향에 영향을 끼치지 않으므로서 수상관이 항상 양호한 색순도를 유지할 수 있게 되는 것이다.According to the present invention configured as described above, the magnetic flux generated in the axial direction of the speaker 1 is absorbed and blocked by the cylindrical ferrite core 7 sandwiched between the coil 6 and the main body 2 and generated in the front and rear directions. The magnetic flux is absorbed by the ferrite plate 4 attached to the rear surface 3 of the speaker body 2 of the present invention, so that other components installed around the speaker 1 as well as the propagation direction of the electron beam of the television receiving tube are affected. The water pipe can always maintain a good color purity without affecting.
또한, 본 고안은 통상의 스피커에 접착판(4)과 페라이트판(7)만을 부착하여도 스피커에서 발생되는 대자현상을 방지할수 있으므로 제작이 용이하고, 대량 생산이 가능하므로 생산 단가를 절감할 수 있는 등 매우 유용한 고안인 것이다.In addition, the present invention can prevent the large magnetic phenomenon generated in the speaker even by attaching only the adhesive plate 4 and the ferrite plate (7) to the conventional speaker, it is easy to manufacture, and mass production is possible, thereby reducing the production cost It is such a useful design.
