본 고안은 원통형요우크를 사용하는 알니코형 스피커에 관한 것으로, 특히 원통형요우크에 결합홈과 삽입홈을 형성시키고 프레임에는 결합돌기를 형성시켜 조립이 쉬워지도록 한 스피커에 관한 것이다.The present invention relates to an alnico type speaker using a cylindrical yoke, and more particularly, to a speaker configured to form a coupling groove and an insertion groove in a cylindrical yoke, and to form an engaging protrusion in a frame to facilitate assembly.

일반적으로 스피커는 전기신호를 음성신호로 변환시켜 주는 것으로서 이는 마그네트의 종류에 따라 페라이트 마그네트형스피커와 알니코형스피커로 크게 구분할 수가 있는바, 그 중 알니코형스피커는 원통형 요우크를 사용하고 있어서, 이 요우크에다 프레임을 결합시켜줄 경우 제1도에 도시되어져 있는 바와 같이 요우크(1)의 상부에다 결합턱(9)을 형성시키고, 이 결합턱(9)에 프레임(8)을 접착시킨 뒤 여기에 상기 결합턱(9)의 상측을 코킹작업으로 절곡시켜 프레임(8)이 결합고정되도록 해주고 있었다.In general, a speaker converts an electrical signal into a voice signal, which can be roughly divided into a ferrite magnet type speaker and an alnico type speaker according to the type of magnet. Among them, the alnico type speaker uses a cylindrical yoke. When the frame is coupled to the yoke, as illustrated in FIG. 1, the coupling jaw 9 is formed on the upper portion of the yoke 1, and the frame 8 is bonded to the coupling jaw 9. After this, the upper side of the coupling jaw (9) was bent by the caulking operation to allow the frame (8) to be fixed.

그러나 이러한 종래의 스피커에서는 코킹작업이 불량하게 되면 프레임이 기울어진 상태로 결합되어져, 진동판의 진동상태를 불량하게 해 주게 될 뿐만 아니라 크레임이 요우크로 부터 떨어지게 되는 등의 문제점이 발생되고 있었다.However, in such a conventional speaker, when the caulking operation is poor, the frame is coupled in an inclined state, which not only causes the vibration state of the diaphragm to be poor, but also the problem of falling the crane from the yoke.

이에 본 고안은 상기와 같은 문제점을 해결하기 위해 고안된 것으로, 요우크에다 결합홈과 삽입홈을 형성시켜 주는 한편 프레임의 결합돌기가 요우크의 삽입홈을 통해 결합홈에 끼워지게 함으로써 조립이 쉽게 이루어지게됨은 물론 프레임과 요우크의 결합력이 향상되도록 된 스피커를 제공함에 그 목적이 있다.Therefore, the present invention is designed to solve the above problems, while forming a coupling groove and an insertion groove in the yoke, the assembly protrusion of the frame is easily assembled by inserting the coupling groove through the insertion groove of the yoke. It is an object of the present invention to provide a speaker that is, of course, to improve the coupling force of the frame and the yoke.

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 요우크(1)의 중앙부에 마그네트(2)가 설치되고, 상기 요우크(1)와 마그네트(2) 사이에는 진동판(3)과 연결된 보이스코일(4)이 설치되면서 상기 요우크(1)의 상부외측에는 결합홈(5)과 함께 다수의 삽입홈(6)이 형성됨, 상기 결합홈(5)에는 다수의 결합돌기(7)가 형성된 프레임(8)이 결합 설치되어 상기 진동판(3)을 지지해 주게 되는 구조로 되어 있다.The present invention is a magnet (2) is installed in the center of the yoke (1), between the yoke (1) and the magnet (2) is installed the voice coil (4) connected to the diaphragm (3) while the yoke ( A plurality of insertion grooves 6 are formed at the upper outer side of the upper part together with the coupling grooves 5, and the frame 8 having the plurality of coupling protrusions 7 is installed at the coupling grooves 5 so that the diaphragm ( It is structured to support 3).

상기와 같은 구조를 갖는 본 고안은, 프레임(8)의 결합돌기(7)를 요우크(1)의 삽입홈(6)을 통해 끼워준 다음 프레임(8)을 돌려주게 되면 상기 결합돌기(7)가 결합홈(5)에 억지끼움식으로 결합되게 되는 것이다.According to the present invention having the structure as described above, the coupling protrusion 7 of the frame 8 is inserted through the insertion groove 6 of the yoke 1 and then the frame 8 is returned to the coupling protrusion 7. Is to be coupled to the coupling groove (5) by interference fit.

한편 제2도는 본 고안에 따른 요부분리 사시도로서, 요우크(1)의 상부외측에 결합홈(5)과 삽입홈(6)이 형성되고, 프레임(8)의 하부에는 결합돌기(7)가 형성되고 있는 것이 도시되어져 있는데, 여기서 상기 결합돌기(7)를 상기 삽입홈(6)에 끼워준 상태에서 프레임(8)을 돌려주게 되면 상기 결합돌기(7)가 결합홈(5)에 억지끼움으로 끼워져 고정되게 되고, 또 결합부위에다 접착제를 도포해주게 도면 결합력을 더욱 높여 줄 수가 있게 된다.On the other hand Figure 2 is a perspective view of the main portion according to the present invention, the coupling groove 5 and the insertion groove 6 is formed on the upper outer side of the yoke 1, the coupling projection 7 is formed on the lower portion of the frame 8 It is shown that the formation of the coupling protrusions (7) to the insertion grooves (6) when the frame (8) is rotated when the coupling projections (7) to the coupling grooves (5) by interference fit It is inserted and fixed, and by applying an adhesive to the bonding portion, it is possible to further increase the bonding strength of the drawings.

이와 같이 해서 프레임(8)이 요우크(1)에 결합 고정되고 마그네트와 구동부가 설치된 상태, 즉 제3도와 같이 스피커의 조립이 완료된 상태에서 보이스코일(4)이 상하 구동되면서 진동판(3)이 진동하게 되어 음압이 발생되게 돈다.In this way, the frame 8 is coupled to the yoke 1 and fixed, and the magnet coil and the driving unit are installed, that is, the voice coil 4 is driven up and down while the speaker is assembled as shown in FIG. It vibrates and turns on sound pressure.

상기와 같이 본 고안은, 종래 프레임(8)이 요우크(1)에 부착시켜진 상태에서 코킹작업을 하던 것과는 달리, 프레임(8)의 결합돌기(7)를 요우크(1)의 삽입홈(6)에다 끼운 다음 프레임(8)을 돌려주게 되면 상기 결합돌기(7)가 결합홈(5)에 억지끼움식으로 결합되게 되므로서 스피커의 조립공정을 단축시켜줄 수 있게 될 뿐만 아니라 프레임(8)와 요우크(1)의 결합상태를 양호하게 하여 스피커의 성능을 향상시킬 수 있는 효과가 있다.As described above, the present invention, unlike the conventional caulking operation in the state that the frame 8 is attached to the yoke 1, the engaging projection 7 of the frame 8 is inserted groove of the yoke 1 When the frame 8 is rotated after the 6 is inserted, the coupling protrusion 7 is coupled to the coupling groove 5 by interference fit, thereby shortening the assembly process of the speaker, as well as the frame 8. ) And the yoke (1) to improve the performance of the speaker can be improved.
