본 고안은 이중의 자기회로부를 갖춘 스피커에 관한 것이다.The present invention relates to a speaker having a dual magnetic circuit portion.
일반적으로 스피커는 자기회로부와 진동판 및 프레임으로 구성되고, 자기회로부는 마그네트가 내장된 요우크 및 보이스코일이 감겨진 보빈으로 이루어진다.In general, the speaker is composed of a magnetic circuit portion, a diaphragm and a frame, the magnetic circuit portion is composed of a yoke and a voice coil wound bobbin with a built-in magnet.
한편, 스피커는 대별하여 코온(CONE)형 스피커와 호온(HORN)형 스피커로 분류하여 코온형 스피커는 오디오 제품의 개발과 더불어 기존의 호온형 스피커를 개량 발전시킨 것이다.On the other hand, the loudspeaker is roughly classified into a CONE type speaker and a HORN type speaker, and the COON type speaker is an improvement of the existing horn type speaker with the development of an audio product.
그러나 상기 스피커 중 호온형 스피커는 코온형 스피커에 비해 전기음향변환능률이 좋기 때문에 출력음압레벨을 대략 6-12DB정도가 높은 98-110DB정도의 값을 갖는다.However, since the horn type speaker has better electroacoustic conversion efficiency than the coon type speaker, the output sound pressure level has a value of about 98-110DB, which is about 6-12DB higher.
따라서, PA용이나 악기용 또는 주위의 소음이 심한 장소에서는 이와 같은 출력음압레벨이 높은 호온 스피커를 사용하고 있다.Therefore, a horn loudspeaker with such a high output sound pressure level is used for PA, a musical instrument, or a place where the surrounding noise is high.
본 고안은 이러한 호온형 스피커를 개량시킨 것인바, 출력이 큰 스피커는 보이스 코일(VOICE COIL)에서 발생하는 일이 많으므로 댐퍼나 보빈의 접착부분에 내열성이 좋은 접착제를 사용해야 하고, 이 열은 외부로 방출시키기 위한 방열기구를 설치해야 하는 번거로움이 따르게 된다.The present invention is an improvement of such a horn type speaker. Since a loud speaker is often generated from a VOICE COIL, a heat-resistant adhesive must be used for the adhesive portion of the damper or bobbin. The hassle of having to install a heat dissipation device to discharge the furnace is accompanied.
즉, 종래의 호온형 스피커에 대한 구조를 보면, 제1도에서 보는 바와 같이, 마그네트(1)와 포올(2, POLE) 및 상, 하부판(3, 4)으로 이루어진 요우크(5) 부분과, 진동판(6)에 접착된 보이스코일(7) (정확히는 보이스코일이 감겨진 보빈)이 엣지(8, EDGE)에 지지된체 상기 엣지(8)가 압착되는 압착부(9) 및 이퀄라이져(10, EQUALIZER)를 내장한 호온(11)으로 이루어져 있다.That is, the structure of the conventional horn type speaker, as shown in Figure 1, the yoke (5) portion consisting of the magnet 1, the poles (2, POLE) and the upper and lower plates (3, 4) and , A voice part 7 bonded to the diaphragm 6 (exactly, a bobbin wound with a voice coil) is supported on an edge 8, EDGE, and a crimp part 9 and an equalizer 10 in which the edge 8 is compressed. It consists of a horn (11) with built-in EQUALIZER.
주지하는 바와 같이 마그네트에서의 자속의 흐름을 보이스코일에 흐르는 전류와 함께 플레밍의 왼손법칙에 적용시키면 보이스코일은 수직승강하는 방향으로 힘을 받아 전동판을 상하로 진동시키케 된다.As is well known, if the flow of magnetic flux in the magnet is applied to the Fleming's left hand law together with the current flowing through the voice coil, the voice coil will vibrate up and down the electric plate by the force in the vertically rising direction.
그런데, 종래의 스피커는 하나의 보이스코일에 댐퍼(DAMPER)도 없이 하나의 엣지 만을 사용하여 진동판을 지지시키므로 보이스코일의 수직승강운동이 비직선성 운동을 행하게 되므로 스피커의 왜율을 발생시키는 문제가 있게 된다.However, since the conventional speaker supports the diaphragm using only one edge without a damper (DAMPER) on one voice coil, the vertical lifting motion of the voice coil performs a non-linear motion, thereby causing distortion of the speaker. do.
이에 본 고안에는 하나의 진동판에 한쌍의 자기회로부를 구성시켜 보이스코일에서 발생되던 열을 양분시키토록 하여 종래의 방열기구설치 등의 번거로움을 해소시키고, 더구나 진동판에 두개의 엣지가 연접해 있으므로 진동판의 비직선성 운동에 의한 왜율 감소시킬 있도륵 한 것이다.Therefore, in the present invention, a pair of magnetic circuits are formed in one diaphragm to divide heat generated from the voice coil to solve the trouble of installing a conventional heat radiating mechanism, and furthermore, two edges are connected to the diaphragm so that the diaphragm It is also possible to reduce the distortion caused by nonlinear movements.
이하 첨부도면을 참고하여 본 고안을 상세히 실명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 상, 하부 마그네트(1, 1')와 포올(2, 2') 및 상, 중, 하 부판(3, 3', 4)으로 외형으로 이루는 요우크(5)와, 압착부(9) 이중엣지(8, 8')에 정착지지되는 진동판(6) 및 상하 보이스코일(7, 7'), 상기 포올(2)의 내공에 위치한 이퀄라이저(10) 및 호온(11)으로 구성된 이중 자기회로부를 갖춘 호온형 스피커이다.The present invention is a yoke (5) consisting of the upper and lower magnets (1, 1 ') and pools (2, 2') and the upper, middle, and lower plates (3, 3 ', 4) and a crimping portion ( 9) a double plate consisting of a diaphragm 6 and upper and lower voice coils 7 and 7 'supported on the double edges 8 and 8', an equalizer 10 and a horn 11 located in the inner hole of the pole 2; It is a horn type speaker with a magnetic circuit part.
즉, 왜율을 최소화시킬 목적으로 진동판(6)의 정확한 수직승강운동만 가능하도록 두개의 보이스코일과 두개의 엣지를 진동판에 일체로 접속시켜 두되, 기존의 스피커가 갖는 자기회로부의 구성 및 역할과 동일하게 하였으므로 하나의 보이스코일을 사용했을 때 야기되는 고열의 발생, 엣지의 지지력이 부족한 가운데, 유발되는 왜율 변형 등을 해소시킬 수 있게 되는바, 마그네트로부터 자장이 형성되어 자속이 포올을 지나게 될때 보이스코일에 흐르는 전류로 진동판이 상하 수직운동을 하게 되고 그 역할은 두개씩의 보이스코일과 엣지가 분담하므로 종래의 것보다 정확하고 확실한 스피커의 성능을 발휘할 수 있게 되는 것이다.That is, the two voice coils and the two edges are integrally connected to the diaphragm so that only the vertical vertical movement of the diaphragm 6 is possible for the purpose of minimizing the distortion, but the configuration and role of the magnetic circuit part of the existing speaker are the same. Therefore, it is possible to solve the occurrence of high heat caused by using a single voice coil, lack of edge support, distortion caused by distortion, etc., when a magnetic field is formed from the magnet and the magnetic flux passes through the pole. The diaphragm moves up and down vertically by the current flowing in it, and its role is divided into two voice coils and edges, so that the speaker performance can be more accurate and reliable than the conventional one.
따라서, 보이스코일에 발생하는 열의 양분으로 방열기구를 설치할 필요가 없음은 물론, 스피커의 수명을 연장할 수 있고, 특히 진동판에 한쌍의 엣지가 접착지지되어 있으므로 진동판의 비직선상에 의한 왜율변형을 감소시킬 수 있는 효과가 있다.Therefore, the heat dissipation mechanism does not need to be installed by nutrients of heat generated in the voice coil, and the life of the speaker can be extended. There is an effect that can be reduced.
