본 고안은 자속 누설 방지용 스피거에 관한 것으로, 특히 스피커 자기회로부의 마그네트와 포올의 구조를 달리하여 자속누설을 억제토록 하는 실용적인 자속누설방지용 스피커에 관한 것이다.The present invention relates to a spigot for preventing magnetic flux leakage, and more particularly, to a practical magnetic flux preventing speaker for preventing magnetic flux leakage by changing the structure of the magnet and the pole of the speaker magnetic circuit part.

자속 누설 방지용 스피커(이하 "방자형 스피커"라 약칭함)라 하면, 스피커의 자기회로부를 구성하는 마그네트에서 자속이 발생됨에 따라 TV 나 CRT등에서는 전파방해, 회로방해를 일으켜 제품 특성에 영항을 미치는 점등을 고려해서 상기 마그네트로부터 형성되는 자속의 외부 누출을 억제 시킬 수 있도륵 개발된 스피커이다.A speaker for preventing magnetic flux leakage (hereinafter, abbreviated as "magnetic shielding speaker") is a light that affects product characteristics by causing radio interference and circuit interruption in a TV or CRT as magnetic flux is generated in a magnet constituting the magnetic circuit part of the speaker. In consideration of this, the speaker was developed to suppress external leakage of the magnetic flux formed from the magnet.

이러한 방자형 스피커의 대별되는 누설자속 소멸 방식은 기존 마그네트와에 다른 또 하나의 마그네트를 같은 극끼리 마주향하도록 장착시켜서 동극끼리의 척력에 의한 자속누설을 억제 시켜 왔고, 그외 다른 방식으로는 아예 마그네트 주위를 덮개로 씌워 두어서 자속누설을 억제 시키도록 하는 방식으로 대별하여 구분해 왔었다.The leakage leakage magnetic flux dissipation method of the magnetic shielding speaker has suppressed magnetic flux leakage caused by the repulsive force of the same poles by mounting another magnet to face the same poles with the existing magnets. The cover has been divided into a way to suppress the leakage of magnetic flux.

그러나, 상기한 종래 방식의 첫번째 예에서처럼 두개의 마그네트릍 겹쳐 설치하므로서 누설자속을 억제 시키는 것은 우선 마그네트의 소요가 배가 된다는 원가 상승의 결접 외에도, 같은 극끼리 마주향해 강압장착 시키는 이유로 인해 마그네트 성능 저하의 원인이 됨은 물론, 마그네드의 자력이 센 스피커는 서로 맞붙이기가 힘들어 작업에 곤란한 점등 부대 결정이 많다However, as in the first example of the conventional method described above, suppressing the leakage flux by installing two magnets overlapping one another, in addition to the cost increase that the requirements of the magnets are doubled, the magnets are deteriorated due to the force-mounting of the same poles facing each other. Of course, magnet magnetized speakers are hard to stick together, and there are many lighting unit decisions that are difficult for work

또한, 상기한 두번째 예에서처럼 마그네크 주위에만 덮개를 씌운 경우는 약간의 누설자속 방지역할은 가능할지 몰라도 시간의 경과에 따라 덮개자체도 자화되어 원하는 만큼의 기능을 기대할 수는 없고 이 덮개를 장착 하는데 따르는 공정수와 재료비의 증가등이 문제가 된다.In addition, if the cover is only covered around the magnet, as in the second example above, it may be possible to prevent some leakage flux, but the cover itself is also magnetized over time, so it is not possible to expect as much function as desired. The increase in the number of processes and material costs that follow is a problem.

이에 본 고안에서는 기존의 스피커에서 자기회로부의 마그네트가 마치 도넛츠 형태로 성형되어 하부판 위체 높여져 포을(POLE)사이에 끼워진 구성을 이루게 되어진 대신 마그네트를 하부판 아래에 접착시키고, 그 하부면에는 덮개(SHlELD-CASE)가 맞닿은 형태로 구성되어져 자속 누설방지는 물론, 현재 생산되는 스피커의 부품 변화 없이 그 특성을 개선시킬 수 있도록한 방자형 스피커를 제공하는데 그 안출 목적이 있다.Therefore, in the present invention, the magnet of the magnetic circuit part of the existing speaker is shaped like a donut and is raised above the lower plate to form a configuration sandwiched between the poles. Instead, the magnet is bonded under the lower plate, and a cover (SHlELD) is provided on the lower surface. -CASE) is designed to be in contact with each other to prevent magnetic flux leakage as well as to provide a magnetic speaker that can improve its characteristics without changing the parts of the current speaker.

이하, 본 고안을 1실시예를 들어 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the embodiment as follows.

본 고안은 자기회로부(1)와 진동부(2) 및 프레임(3)으로 이루어지는 방자형 스피커에서, 상기 자기회로부(1)를 이루는 마그네트(4)를 하부판(5)아래에 접착시키되, 자속이 발생되어 진행하는 N극이 포올(6)쪽을 향하도록하고, 상기 마그네트 하부는 상부판(8)에 지지고정되는 덮개(7)의 밀판이 밀착되어 이루어진 방자형 스피커이다.The present invention, in the magnetic shield consisting of a magnetic circuit portion 1, a vibrating portion 2 and the frame (3), the magnet (4) constituting the magnetic circuit portion 1 is bonded to the bottom plate 5, the magnetic flux is generated The N pole is to be directed toward the pole (6), and the lower part of the magnet is a magnetic shield made of a close contact of the cover plate of the cover (7) fixed to the upper plate (8).

즉, 스피커 자기회로부는 덮개(7)내에 포올(6)과 마그네트(4)가 내장된 구조를 이루되, 아래로부터 차례로 마그네트(4),하부판(5)과 일체형의 포올(6)이 접착된 구성을 이루게 되어 있다.That is, the speaker magnetic circuit part has a structure in which the poles 6 and the magnets 4 are built in the cover 7, and the magnets 4 and the bottom plate 5 and the integral poles 6 are sequentially bonded from below. It is supposed to be composed.

따라서, N극에서 발생되는 자속은 S극으로 들어가게 되므로 이 예에서도 마그네트(4)로부터 발생된 자속은 포올(6)에서 상부판(8)을 거쳐 덮개(7)를 타고 흘러 S극으로 들어가는 자장을 형성하게 된다.Therefore, since the magnetic flux generated at the north pole enters the south pole, in this example, the magnetic flux generated from the magnet 4 flows through the cover 7 through the top plate 8 at the pole 6 and enters the south pole. Will form.

상기와 같은 구성을 이루는 방자형 스피커는 자속의 흐름이 자기 회로부내에서만 형성되므로 자속 누설의 영향이 적고, 특히 덮개(7)를 이용한 자속유도를 형성시키므로서 종래의 방자형 스피커에서 야기되던 문제점, 즉 마그네트 2개를 사용하므로서 재료비 및 장착의 어려움의 해소되고, 또한 마그네트와 하부플레이트를 접착 시킨 후 게이지를 이용하여 중심을 잡은 후 덮개를 씌워 주므로 작업공정을 줄일 수 있는 효과가 있다.Since the magnetic flux is formed only in the magnetic circuit part, the magnetic shield having the above-described configuration has less influence of magnetic flux leakage, and in particular, the magnetic flux induction using the cover 7 is formed, that is, the magnet is caused by the conventional magnetic shield. By using the two, the material cost and difficulty of mounting are eliminated, and the magnet is attached to the lower plate, and then the center is covered by the gauge and the cover is covered, thereby reducing the work process.
