본 고안은 스피커에 관한 것으로, 특히 하부플레이트와 센터롤이 ＂＂ 형상으로 절곡형성되고 이 센터폴하면에 프레임이 부착, 설치된 스피커에 관한 것이다.The present invention relates to a speaker, in particular the lower plate and the center roll The present invention relates to a speaker that is bent into a shape of a fan and has a frame attached to the bottom of the center pole.

일반적으로 스피커는 전기신호를 음성신호로 변환시켜 주기 위한 장치로서, 그 중 다이나믹형 스피커가 비교적 그 구조가 간단하고 변환효울이 높을 뿐만 아니라 광범위한 음성재생대역에 걸쳐 양호한 특성을 나타내주기 때문에 폭넓게 사용되고 있다.Generally, a speaker is a device for converting an electrical signal into a voice signal, and a dynamic speaker is widely used because of its relatively simple structure, high conversion efficiency, and good characteristics over a wide range of voice reproduction bands. .

한편 이러한 종래의 다이나믹형 스피커는 제1도에 도시되어져 있는 바와 같이, 상부 및 하부플레이트(3,1)와 페라이트마그네트(2) 및 센터폴(4)로 자기회로가 구성되면서, 상부 플레이트(3) 상면에는 프레임(5)이, 하부플레이트(1) 하면에는 반발마그네트(10)가 각각 부착되고, 상기 자기 회로의 외측에는 차폐막(11)이 설치된 구조로 되어, 상기 반발마그네트(10)와 차폐막(11)이 자속이 누설되는 것을 방지해주도록 되어 있다.Meanwhile, as shown in FIG. 1, the conventional dynamic speaker includes a magnetic circuit composed of upper and lower plates 3 and 1, ferrite magnets 2 and center poles 4, and an upper plate 3 as shown in FIG. The upper surface of the frame 5, the lower plate (1) is attached to the repellent magnet 10, the outer side of the magnetic circuit is provided with a shielding film 11 structure, the repulsive magnet 10 and the shielding film (11) is to prevent the magnetic flux from leaking.

그런데 이와 같은 종래의 스피커구조에 있어서는, 차폐막이 반발마그네트와 페라이트마그네트에 접착되어 있기 때문에 자성을 띠게됨으로써 주위에 설치된 회로소자에 영향을 끼쳐 조립제품의 성능을 떨어지게 할뿐만 아니라, 외부로 자속이 누설되어 스피커의 출력음압특성을 나빠지게 하는 문제점과 함께 제품의 조립공정이 복잡해지는 등의 문제점이 있었다.However, in such a conventional speaker structure, since the shielding film is adhered to the repulsive magnet and the ferrite magnet, it becomes magnetic, thereby affecting the circuit elements installed in the surroundings, thereby degrading the performance of the assembled product and leaking magnetic flux to the outside. As a result, the output sound pressure characteristics of the speaker are deteriorated, and the assembly process of the product is complicated.

이에 본 고안은 상기와 같은 문제점을 해결해주기 위해 고안된 것으로, 하부플레이트와 센터폴을 ＂＂ 형상으로 절곡, 형성시켜 놓으면서 상기 센터폴하면에다 프레임을 연결 부착시켜 주므로서, 조립공정이 간단해지도록 하면서 자속의 누설을 방지할 수 있도록 된 스피커를 제공함에 그 목적이 있다.The present invention is designed to solve the above problems, the lower plate and the center pole ＂ It is an object of the present invention to provide a speaker that is capable of preventing leakage of magnetic flux while simplifying the assembling process by attaching and attaching a frame to the bottom of the center pole while bending and forming it in a shape.

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 ＂＂ 형상의 하부플레이트(1)상에 마그네트(2)와 상부플레이트(3)가 차례로 부착되면서 상기 하부플레이트(1)의 센터폴(4) 하면에는 프레임(5)이 부착되고, 상기 상부플레이트(3)와 센터폴(4) 사이에는 진동판(6)과 연결된 보이스코일(7)이 설치된 구조로 되어 있다.This invention is When the magnet 2 and the upper plate 3 are sequentially attached to the lower plate 1 having a ＂shape, the frame 5 is attached to the lower surface of the center pole 4 of the lower plate 1, and the upper plate ( Between the 3) and the center pole 4 has a structure in which a voice coil 7 connected to the diaphragm 6 is installed.

상기와 같은 구조로 된 본 고안은, 상부플레이트(3)와 마그네트(2) 및 ＂＂ 형상의 하부플레이트(1)가 자기회로를 구성해주게 되고, 또 상기 하부플레이트(1)의 센터폴(4)하면에 부착된 프레임(5)이 상기 하부플레이트(1)와 일정거리로 떨어져 있게되어 자속이 누설되는 것을 방지해주게 된다.The present invention has a structure as described above, the upper plate (3) and the magnet (2) and ＂ The lower plate 1 having a ＂shape constitutes a magnetic circuit, and the frame 5 attached to the lower surface of the center pole 4 of the lower plate 1 is separated from the lower plate 1 by a predetermined distance. This prevents the magnetic flux from leaking.

한편, 제2도는 본 고안의 단면도로서, 하부플레이트(1)가 ＂＂ 형상으로 형성되어 센터폴(4)을 구성해주고, 프레임(5)은 그 중앙부가 ＂＂ 형으로 형성되어 상기 센터폴(4) 하면에 부착되면서 그 저면부위가 하부플레이트(1)와 적당한 간격으로 떨어져 있음이 도시되어져 있는데, 이렇게 프레임(5)이 차폐막기능을 하게되면서 자속이 누설되는 것을 방지해주게 된다. 여기서 상기 센터폴(4)은 하부플레이트(1)를 성형시 프레스공정으로 쉽게 형성시켜 줄 수 있다.On the other hand, Figure 2 is a cross-sectional view of the subject innovation, the lower plate (1) The center pole 4 is formed in the shape of a shape, and the center of the frame 5 is It is shown that the bottom portion is formed in the shape of a 폴 type and attached to the lower surface of the center pole (4) at a suitable interval from the lower plate (1), so that the magnetic flux leaks while the frame (5) functions as a shielding film. To prevent it. Here, the center pole 4 can be easily formed by a press process when forming the lower plate (1).

이와 같이 본 고안은 ＂＂ 형상의 하부플레이트(1)와 마그네트(2) 및 상부플레이트(3)에 의해 자기회로가 구성되어 보이스코일(7)을 흐르는 전류에 의해 진동판(6)이 진동되어져 음압이 발생하게 되는 것이다.In this way, the present invention The magnetic plate is composed of the lower plate 1, the magnet 2, and the upper plate 3 having a ＂shape, and the diaphragm 6 is vibrated by the current flowing through the voice coil 7, thereby generating a sound pressure.

상기와 같은 구조와 작용에 의하여 본 고안은, 하부플레이트(1)와 센터폴(4)을 프레스공정으로 간단히 생산해낼 수 있게되고, 또 반발마그네트와 차폐막이 필요없이 프레임(5)자체에 의해 자속이 누설되는 것을 방지해 줄 수 있게 됨으로써, 스피커의 생산성을 높일 수 있게 될뿐만 아니라 출력음압특성을 향상시켜 줄 수 있는 효과가 있다.By the above-described structure and action, the present invention can produce the lower plate 1 and the center pole 4 simply by the pressing process, and the magnetic flux by the frame 5 itself without the need of a repulsive magnet and a shielding film. By being able to prevent the leakage, it is possible not only to increase the productivity of the speaker but also to improve the output sound pressure characteristics.
