본 발명은 스피커의 보이스코일포머에 관한 것으로 특히 전체적인 외관이 어느 일측으로 길다란 구조의 오발트랙타입(Oval/Track type)의 슬림형태로 구현토록 하여 장방형의 슬림타입에 저음의 구현이 가능하고, 왜율을 감소시켜 고음질을 구현하기 위한 스피커의 구조를 취하기 위하여 보이스코일포머를 슬림타입의 장방형으로 구현할 경우에 보이스코일포머가 내측으로 휘어짐이 발생되어짐을 방지하기 위한 것이다.The present invention relates to a voice coilformer of a speaker. In particular, the overall appearance is long in either side, so that it can be implemented in a slim shape of the Oval / Track type, so that bass sounds can be implemented in a rectangular slim type. In order to take the structure of the speaker to realize a high sound quality by reducing the shape of the voice coil former to implement a slim type of the rectangular shape is to prevent the voice coil former to be inwardly generated.

현재 대부분의 장방형의 스피커는 원형의 보이스코일포머에 진동판만을 콘타입으로 하여 장방형으로 구현토록 한 것으로, 이는 장방형의 보이스코일포머를 사용할 경우에는 보이스코일포머에 권취되어진 보이스코일에서 발생되는 열에 의하여 보이스코일포머가 내측으로 오그라드는 현상이 발생됨으로 간섭에 의하여 안정적인 출력특성을 갖지 못하기 때문이다.Currently, most rectangular speakers have a circular voice coil former and only a diaphragm as a cone type, which is implemented as a rectangular type. When the rectangular voice coil former is used, it is caused by the heat generated from the voice coil wound around the voice coil former. This is because the coil former does not have a stable output characteristic due to interference because the phenomenon occurs.

즉 오발타입의 슬림형의 스피커 구현을 위하여 장방형의 보이스코일포머를 사용할 경우에 보이스코일포머 자체의 구조적인 부분으로 인하여 중앙부분이 내측으로 오그라들게 된다는 것이고, 특히 상기 보이스코일포머에 권취되어진 보이스코일에서 전류가 흐를 경우에 발생되는 열에 의하여 보이스코일포머가 내측으로 쉽게 오그라드는 현상이 발생됨으로 보이스코일포머가 결합되어지는 스피커 유니트 내의 요크(Yoke)와 그 내부에 위치되는 영구자석 사이의 갭(gap)에 끼워진 상태에서 상하 이동될 경우에 간섭이 발생되기 때문이다.In other words, when the rectangular voice coil former is used to implement the slim speaker of the oval type, the central part is shrunk inward due to the structural part of the voice coil former itself, and especially in the voice coil wound around the voice coil former. The gap between the yoke in the speaker unit to which the voice coil former is coupled and the permanent magnet located therein is caused by the heat generated when current flows, causing the voice coil former to be easily deformed inward. This is because interference occurs when it is moved up and down in the state of being fitted in the.

따라서 최근에 이러한 장방형의 보이스코일포머를 사용하면서도 내측으로 오무라듬을 방지하기 위하여 보이수코일포머의 중간에 보강대를 형성토록 하거나 또 는 등분되어진 보이스코일포머를 접착토록 함으로서 내측으로 오그라드는 현상을 방지하고 있는 것이다.Therefore, in order to prevent the curling inward while using such a rectangular voice coil former, it is possible to prevent a gradation inward by attaching a reinforcing bar in the middle of the visible water coil former or by bonding the equally divided voice coil former. I'm doing it.

그러나 이러한 것의 단점은 보이스코일포머의 살두께가 아주 얇은 형태를 취하게 됨으로 장방형의 보이스코일의 중간에 보강대를 고정토록 한다는 것이 불가능하고, 또한 등분되어진 것을 접착토록 할 경우에는 중간대의 두께가 두꺼워지면서 중량의 차이로 상하 진폭이동시 형태의 변형이 발생될 수 있다는 것이다.However, the disadvantage of this is that the thickness of the voice coil former is very thin, so it is impossible to fix the reinforcement in the middle of the rectangular voice coil, and when the adhesive is divided into equal parts, the middle thickness becomes thick. The difference in weight may cause deformation of the shape when the amplitude is moved up and down.

따라서 본원출원인이 선출원한 것에서는 통상 보이스코일포머가 진동판과 결합되어진다는 점을 착안하여 진동판의 이면으로 격판을 장착하여 상기 격판이 보이스코일포머의 내측에 기워지도록 함으로서 장방형의 진동판이 내측으로 오무라드는 것을 방지토록 하였다.Therefore, the applicant of the present application, in the case that the voice coil former is usually combined with the diaphragm, the diaphragm is mounted on the back of the diaphragm so that the diaphragm is inclined inside the voice coil former so that the rectangular diaphragm is inward. Preventing Murad.

그러나 이러한 것의 단점이 격판이 보이스코일의 내측에 끼워진 이후에도 격판을 보이스코일포머와 접착고정하여야 함으로 격판을 진동판에 고정하기도 곤란하지만 이러한 격판을 보이스코일포머의 내측에 끼움토록 한 후 고정?? 하는 2중의 작업이 요구된다는 단점이 있는 것이고, 또한 진동판에 격판을 고정하기 위하여는 부드럽고 유연한 진동판의 재질에는적용이 곤란하다는 단점이 있는 것이었다.However, the disadvantage of this is that even after the diaphragm is fitted inside the voice coil, it is difficult to fix the diaphragm to the diaphragm because the diaphragm must be fixed to the inside of the voice coil former. There is a disadvantage in that a double operation is required, and in addition, in order to fix the diaphragm to the diaphragm, it is difficult to apply to the material of the soft and flexible diaphragm.

따라서 본 발명에서는 이러한 문제점의 해결을 위하여 보이스코일포머의 상측을 일정길이로 하단방향으로 절개하여 절개부를 형성하고, 상기 절개부에 끼움되어지게 보강판을 장착함으로서 유연한 진동판의 사용이 가능하게 되면서 작업성을 향상토록 한 것이다.Therefore, in the present invention, in order to solve this problem, the upper side of the voice coil former is cut to a predetermined length in a lower direction to form an incision, and the flexible diaphragm can be used by mounting a reinforcement plate to be fitted to the incision. It is to improve sex.

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 장방형의 보이스코일포머(10)에는 하단에 보이스코일(3)이 권취되어져 있고 그 상측으로 일정간격으로 절개되어져 절개부(12)가 형성되고, 보이스코일포머(10)의 내공간(11)에는 보강판(20)이 끼워지면서 보강판(20)의 양변에 형성된 절개부(21)가 보이스코일포머(10)의 절개부(12)에 서로 맞물리면서 끼워지는 구성이다.First of all, the basic structure of the present invention has a rectangular voice coil former 10 in which a voice coil 3 is wound at a lower end thereof, and is cut at a predetermined interval thereon to form an incision 12, thereby forming a voice coil former 10. Reinforcement plate 20 is fitted in the inner space 11 of the) is a configuration in which the cutout portion 21 formed on both sides of the reinforcement plate 20 is fitted while being engaged with the cutout portion 12 of the voice coil former 10. .

이때 보강판(20)은 플라스틱으로 성형되어진 것이거나 또는 얇은 금속판을 사용할 수 있는 것이고, 얇고 가벼운 재질이면 어떠한 것을 사용할 수 있는 것이다.At this time, the reinforcing plate 20 is molded in plastic or can use a thin metal plate, if the thin and light material can be used for anything.

또한 보강판(20)이 보이스코일포머(10)의 내공간(11)에 끼워질 경우에 끼워진 상태에서는 내공간(11)의 상측으로 보강판(20)이 돌출되어지지 않는 것이고, 이러한 돌출을 방지하기 위하여 절개부(12,21)가 서로 대응되게 맞물림되면서 결합토록 한 것이다.In addition, when the reinforcing plate 20 is fitted in the inner space 11 of the voice coil former 10, the reinforcing plate 20 does not protrude upward of the inner space 11, and such protrusion is performed. In order to prevent the incisions (12, 21) are to be engaged with each other to correspond to each other.

또한 보강판(20)의 양변에 형성된 절개부(21)에 의하여 보이스코일포머(10)의 내공간(11)에 끼워지면서 측벽(13)으로 돌출되어지는 돌출부(23)는 보이스코일(30)이 권취되어진 부분끼지 끼워지거나 보이스코일(30)이 권취되어진 부분의 상측까지만 끼워질 수 있는 것이다.In addition, the protrusion 23 protruding into the side wall 13 while being fitted into the inner space 11 of the voice coil former 10 by the cutouts 21 formed on both sides of the reinforcing plate 20 is the voice coil 30. This wound portion is sandwiched or only the upper side of the portion where the voice coil 30 is wound.

우수한 보강을 위하여는 보이스코일(30)이 권취어진 부분까지 끼워지는 것이 좋은 것이다.For excellent reinforcement, it is good that the voice coil 30 is fitted to the wound part.

이때에는 보이스코일(30)의 두께만큼 절개부(21)의 형태도 다단으로 구현토록 하게 되는 것이다.At this time, the shape of the cutout portion 21 is to be implemented in multiple stages as the thickness of the voice coil (30).

또한 보강판(20)이 보이스코일포머(10)와 결합되면서 돌출되어지는 돌출부(23)는 상측으로는 경사면(24)을 형성토록 하여 진동판(40)과의 결합시 간섭을 제거토록 한 것이다.In addition, the protrusion 23 protruding while the reinforcing plate 20 is coupled to the voice coil former 10 is formed to form an inclined surface 24 upward to remove interference when the diaphragm 40 is coupled to the diaphragm 40.

따라서 보이스코일포머(10)를 진동판(40)과 결합하면 보이스코일포머(10)의 내공간(11)에 보강판(20)이 끼워진 상태에서 상측으로 돌출되어지는 부분이 없어 긴밀한 결합이 가능하게 되는 것이다.Therefore, when the voice coil former 10 is combined with the diaphragm 40, there is no part protruding upward in the state where the reinforcing plate 20 is fitted in the inner space 11 of the voice coil former 10, thereby enabling close coupling. Will be.

또한 보이스코일포머(10)의 절개부(12)에 의하여 보강판(20)이 서로 맞물림되어지면서 결합됨으로 결합력이 우수하게 되는 것이고, 이와 같이 결합된 상태에서 접착제 등을 이용하여 고정토록 함으로서 제조의 간편함을 제공하게 되는 것이다.In addition, the reinforcing plate 20 is coupled to each other by the cutout portion 12 of the voice coil former 10 is coupled to each other to be excellent bonding force, so as to be fixed by using an adhesive or the like in the combined state of the It will provide simplicity.

따라서 장방형의 보이스코일포머에 보강판이 직접결합되어짐으로 진동판의 재질을 다양한 것을 사용할 수 있음은 물론 보이스코일포머와 진동판과의 결합이 용이하게 되는 것이다.Therefore, since the reinforcing plate is directly coupled to the rectangular voice coil former, various materials of the diaphragm may be used, and the coupling between the voice coil former and the diaphragm becomes easy.
