본 발명은 스피커에 관한 것으로 특히 그 목적이 전체적인 외관이 어느 일측으로 길다란 구조의 오발트랙타입(Oval/Track type)의 슬림형태로 구현토록 하기 위하여 구현되어지는 보이스코일포머를 슬림타입의 장방형으로 구현할 경우에 상기 보이스코일포머에 권취되어진 코일에서 발생되는 열에 의하여 내측으로 휘어짐이 발생되어짐을 방지하기 위한 것이고 이를 위한 수단이 간단하게 이루어지도록 한 것이고, 이로 인하여 생산성을 향상토록 한 것이다.The present invention relates to a loudspeaker, and in particular, an object of which a voice coilformer, which is implemented to implement a slim shape of an Oval / Track type having an overall appearance of which is long to one side, can be implemented in a slim type rectangle. In this case, it is to prevent the warpage from occurring due to the heat generated from the coil wound around the voice coil former and to simplify the means therefor, thereby improving productivity.

현재 슬림형의 스피커 구현을 위하여 장방형의 보이스코일포머를 사용할 경우에 보이스코일포머 자체의 구조적인 부분으로 인하여 중앙부분이 내측으로 오그라들게 된다는 것이고, 특히 상기 보이스코일포머에 권취되어진 보이스코일에서 발생되는 열에 의하여 보이스코일포머가 내측으로 쉽게 오그라드는 현상이 발생됨으로 보이스코일포머가 결합되어지는 스피커 유니트 내의 영구자석 사이의 갭(gap)에 끼워진 상태에서 상하 이동될 경우에 간섭이 발생된다는 것이다.When the rectangular voice coil former is used to implement a slim speaker, the central part is shrunk inward due to the structural part of the voice coil former itself. As a result, the voice coil former is easily deformed to the inside, and thus interference occurs when the voice coil former is moved up and down while being fitted in the gap between the permanent magnets in the speaker unit to which the voice coil former is coupled.

따라서 이러한 간섭에 의하여 안정적인 출력특성을 갖지 못한다는 단점이 있어 도7에 도시된 바와 같이 최근에는 이러한 보이스코일포머의 중간에 일체로 일정간격을 유지하면서 보강대를 형성토록 하거나 또는 다수개로 등분되어진 보이스코일포머를 대응되는 면을 서로 접착토록 함으로서 보강대를 구현토록 하여 보이스코일포머가 내측으로 오그라드는 현상을 방지하고 있는 것이다.Therefore, there is a disadvantage in that it does not have a stable output characteristics due to such interference, as shown in Figure 7 Recently, the voice coil is formed to maintain the reinforcement while maintaining a constant interval integrally in the middle of the voice coil former or divided into a plurality of voice coils The former is bonded to each other to form a reinforcing rod, thereby preventing the voice coil former from being shriveled inward.

그러나 이러한 것의 단점은 보이스코일포머의 살두께가 아주 ??은 살두께를 갖고 있기 때문에 보강대가 일체로 형성된 상태에서의 실질적인 생산이 불가능하다는 것이고 생산할 경우에도 생산성이 열악하여 경제적이지 못하다는 단점이 있는 것이다.However, the disadvantage of this is that the thickness of the boy coilformer has a very thin thickness, so that practical production is impossible in the state where the reinforcing rod is integrally formed. will be.

또한 도8에 도시된 바와 같이 접착의 방식으로 대응되는 면을 접착토록 하는 것은 접착에 의한 대응되는 면의 두께가 두꺼워지게 되면서 전체적인 좌우 중량의 차이로 상하 진폭이동시 형태의 변형이 발생된다는 것이고 이러한 접착이 정밀하지 못할 경우에는 정확한 장방형의 구조를 취할 수 없게 되고 이러한 정밀한 접착을 위하여는 결국 생산성이 나빠 실질적인 사용에 많은 문제점이 있다는 것이다.In addition, as shown in FIG. 8, the adhesion of the corresponding surface by the method of adhesion means that the thickness of the corresponding surface by the adhesion becomes thick and deformation of the shape occurs when the amplitude is moved up and down by the difference in the overall left and right weights. If it is not precise, it is impossible to take an accurate rectangular structure, and for such precise bonding, there is a problem in practical use because of poor productivity.

따라서 본 발명에서는 보이스코일포머가 진동판과 결합되어진다는 점을 착안하여 진동판의 이면으로 격판을 장착하여 상기 격판이 보이스코일포머의 내공간에 끼워지면서 보이스코일포머가 오그라드는 현상을 방지토록 한 것이다.Therefore, in the present invention, the voice coil former is combined with the diaphragm, and the diaphragm is mounted on the back of the diaphragm to prevent the voice coil former from degrading while the diaphragm is fitted into the inner space of the voice coil former. .

이하 첨부도면에 의거 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

우선 본원발명에서의 구성이 종래의 구성과 동일한 기술사상일 경우에는 서로 동일한 도면부호를 사용하였다.First of all, when the configuration in the present invention is the same technical idea as the conventional configuration, the same reference numerals are used.

우선 본 발명에서의 기본적인 구조는 진동판(20)이 보이스코일포머(10)와 결합되어지는 이면으로 보이스코일포머(10)의 내공간(11)에 긴밀하게 끼워지도록 격판(21)을 구현토록 한 것이다.First, in the present invention, the diaphragm 20 is a back surface coupled to the voice coil former 10 so that the diaphragm 21 may be implemented to be tightly fitted into the inner space 11 of the voice coil former 10. will be.

이를 위한 구조로는 도1 및 도 2에 도시된 바와 같이 장방형으로 이루어지는 진동판(20)의 이면으로는 격판(21)을 고정토록 하기 위하여 이면에는 돌출테(27)를 구비토록 하고 상기 돌출테(27)의 내측으로 격판(21)을 끼움토록 하면서 고정토록 하는 것이다.1 and 2, the rear surface of the diaphragm 20 having a rectangular shape is provided with a protruding frame 27 on the rear surface of the diaphragm 20 to fix the diaphragm 21. 27 is to be fixed while fitting the diaphragm 21 into the inner side.

이때 격판(21)은 보이스코일포머(10)의 길이에 따라 단수 도는 복수로 선택적으로 사용되어지는 것이고, 격판(21)의 하단에는 걸림턱(23)을 구비하여 상기 격판(21)이 보이스코일포머(10)의 내공간(11)에 끼워진 상태에서 보이스코일포머(10)가 걸림턱(23)에 걸려 놓여지도록 하는 것이다.At this time, the diaphragm 21 is to be selectively used in a singular or plural number according to the length of the voice coil former 10, the lower end of the diaphragm 21 is provided with a locking jaw 23, the diaphragm 21 is a voice coil In the state of being fitted into the inner space 11 of the former 10, the voice coil former 10 is to be hung on the locking step (23).

또한 상기 격판(21)의 하단에는 결합돌기(25)를 구비토록 하고, 상기 격판(21)이 보이스코일포머(10)의 내공간(11)에 끼워진 상태에서 결합홈(26a)을 갖는 받침대(26)를 결합토록 함으로서 보이스코일포머(10)가 결합된 상태에서 격판(21)과 탈리되는 현상을 방지하게 되는 것이다.In addition, the lower end of the diaphragm 21 is provided with a coupling protrusion 25, the pedestal having a coupling groove 26a in a state where the diaphragm 21 is fitted into the inner space 11 of the voice coil former 10 ( By combining the 26) it is to prevent the separation of the diaphragm 21 and the diaphragm 21 in the voice coil former 10 is coupled.

또한 도6a에 도시된 바와 같이 보이스코일포머(10)의 내공간(11)에 끼워지는 격판(21)을 판상이 아닌 축(22)의 형태를 취할 경우에도 동일한 효과를 얻을 수 있는 것이고, 상기 축(22)의 하단에도 마찬가지로 걸림턱(23a)을 구비토록 함으로서 보이스코일포머(10)가 축(22)과 결합된 상태에서 내측으로 오그라드는 현상을 방지할 수 있는 것이다.Also, as shown in FIG. 6A, the same effect can be obtained when the diaphragm 21 fitted into the inner space 11 of the voice coil former 10 takes the form of a shaft 22 rather than a plate. Similarly, the lower end of the shaft 22 is provided with a locking step 23a to prevent the phenomenon that the voice coil former 10 is inwardly engaged in a state in which the voice coil former 10 is coupled to the shaft 22.

따라서 보이스코일포머(10)를 진동판(20)과 결합할 경우에 보이스코일포머(10)를 진동판(20)의 이면에 장착된 격판(21) 또는 축(22)과 결합토록 하면 됨으로 제조가 용이하게 되는 것이고, 또한 보이스코일포머(10)가 진동판(20)에 장착된 격판(21) 또는 축(22)의 걸림턱(23,23a)에 걸려 안착되어짐으로 별도의 보이스코일 포머(10)를 고정시킬 필요가 없게 되어 간단하게 제작되어질 수 있는 것이다.Therefore, when the voice coil former 10 is combined with the diaphragm 20, the voice coil former 10 may be easily combined with the diaphragm 21 or the shaft 22 mounted on the rear surface of the diaphragm 20. In addition, since the voice coil former 10 is caught by the latching jaws 23 and 23a of the diaphragm 21 or the shaft 22 mounted on the diaphragm 20, the separate voice coil former 10 is formed. It does not need to be fixed and can be manufactured simply.

또한 격판(21)이 진동판(20)의 돌출테(27)의 내측에 접착 등의 방식으로 고정됨으로 견고한 고정이 가능하게 되는 것이다. In addition, since the diaphragm 21 is fixed to the inner side of the protruding frame 27 of the diaphragm 20 by bonding or the like, a rigid fixing is possible.

따라서 장방형의 보이스코일포머가 구조적이거나 도는 코일에서 발생되는 열에 의하여 내측으로 오그라드는 현상을 진동판의 격판에 의하여 간단하게 해결하게 됨으로 제조의 용이성은 물론 조립의 용이성을 제공하게 되는 것이다.Therefore, since the rectangular voice coil former is easily solved by the diaphragm of the diaphragm, it is easy to manufacture as well as to facilitate the assembling of the inside of the coil by the heat generated from the structural or turning coils.
