본 고안은 저음역용 스피커의 구조에 관한 것으로 스피커에서 재생되는 음질을 좌우하흔 진동판을 질량이 무거운 종이재질로써 구성하되, 반구형의 무제한 지향성 콘지로 구성하여 스피커의 정면이나 측면 등의 어느 위치에서 음을 듣더라도 고른 음의 세기가 전달되도록 함으로써 고품질의 우파스피커를 제공토록함에 그 목적이 있는 것이다.The present invention relates to the structure of a low-end speaker, and the diaphragm is composed of a heavy paper material, which determines the sound quality reproduced by the speaker, and is composed of a hemispherical unlimited directional cone so that the sound is generated at any position such as the front or side of the speaker. The objective is to provide a high quality right speaker by allowing even loudness to be transmitted even when listening.
종래의 일반적인 우파에 있어서는 진동판을 설치하되 일정각도를 유지하는 콘형태의 진동판을 사용해 왔기 때문에 음의 세기가 청취하는 위치에 따라 심한 차이를 보이는 결점이 있었다.In the conventional general right wave, since the diaphragm in the shape of a cone is installed but maintains a constant angle, there is a drawback that the sound intensity varies greatly depending on the listening position.
즉, 제 3 도에서 나타난 바와같이 스피커의 정면위치에서 측면위치로 이동하면서 음을 듣게되면 그 음의 세기가 측면에서는 현격한 차이로 감쇄하는 현상을 발견할 수가 있는 것이다.That is, as shown in FIG. 3, when the sound is heard while moving from the front position to the side position of the speaker, the intensity of the sound is attenuated by a remarkable difference in the side.
한편 트위타나 미드레인지 스피커의 구조에 있어서는 천으로 구성된 질량이 가벼운 도움형 진동판이 개량되어 통용되고 있으나 저음역용 스피커에 있어서는 고음역용 스피커에 사용되는 천재질의 도움형 진동판을 사용할 수가 없었기 때문에 그대로 콘형태의 진동판을 사용할 수밖에 없었던 것이다.On the other hand, in the structure of tweeter and midrange speaker, the help type diaphragm with light weight made of cloth is improved and used, but in the low range speaker, it is not possible to use the help type diaphragm made of high quality speaker. There was no choice but to use a diaphragm.
그 이유는 저음의 경우는 공기를 밀어내는 힘이 강해야 하므로 만약 천재질의 도움형진동판을 사용하게되면 웅장한 음을 내야하는 스피커가 제구실을 못하게 되는 문제가 발생하였던 것이다.The reason for this is that in the case of bass, the force to push the air must be strong, so if you use the genius help type vibration plate, the speaker that has to make a loud sound will not be able to get out of the control room.
본 고안은 상기와 같은 종래의 저음역용 스피커의 제결함을 감안하여 강한 힘으로 공기를 밀어내기에 충분한 재질특성을 갖는 종이재질의 진동판을 반구형으로 구성하여 무제한 지향성의 특성을 갖도록 안출한 것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention is made in consideration of the defects of the conventional low-end speaker as described above, the paper diaphragm having a material characteristic enough to push out the air with a strong force is composed of a hemispherical shape to have a characteristic of unlimited directivity attached to this When described in detail based on the drawings as follows.
스피커본체(1) 상부에 댐퍼(2)를 형성하여서 이루어지는 저음역용 스피커에 있어서 브라켓(3)에 장착된 스피커 본체(1)를 무제한 지향성 특성을 갖는 펄프지(종이) 또는 폴리프로필렌(P.P) 재질의 반구형 진동판(4)을 상기 브라켓(3)에 진동가능토록 포설하여서 이루어진 것으로 본 반구형 진동판(4)은 진동억제용 댐퍼(2)에 연결된 보빈(6)과 드라이브 콘(5)에 의하여 일체적으로 연결되어 있다.In the low frequency speaker formed by forming the damper 2 on the speaker body 1, the speaker body 1 mounted on the bracket 3 is made of pulp paper (paper) or polypropylene (PP) material having unlimited directivity. The hemispherical diaphragm 4, which is formed by vibrating the hemispherical diaphragm 4 on the bracket 3, is integrally formed by a bobbin 6 and a drive cone 5 connected to a vibration suppression damper 2. Is connected.
이와같이 구성된 본 고안의 작용 및 그 효과를 설명하면, 스피커 본체(1)에 설치된 전자석내의 보이스코일에 전류가 통하게 되면 상하로 작용하는 힘에 의하여 댐퍼(2)에 부착된 보빈(6)이 상하로 떨게되므로 여기에 일체적으로 연결된 드라이브콘(5)을 통하여 반구형(도움형) 진동판(4)으로 진동력이 전달되어 진동판(4)에 접해있는 공기를 진동시켜 우파특유의 웅장한 저음을 재생시키게 되는 것으로 진동판(4)이 반구형으로 구성되어 있기 때문에 청취자의 위치에 관계없이 제 2 도의 그래프에서와 같이 거의 일정한 세기의 음을 들을수가 있게 되는 것이다.Referring to the operation and effects of the present invention configured as described above, when the current flows through the voice coil in the electromagnet installed in the speaker body 1, the bobbin 6 attached to the damper 2 is moved up and down by a force acting up and down. The vibration force is transmitted to the hemispherical (help type) diaphragm 4 through the drive cone 5 integrally connected thereto to vibrate air contacting the diaphragm 4 to reproduce the magnificent bass unique to the right wave. Since the diaphragm 4 is formed in a hemispherical shape, the sound of almost constant intensity can be heard as shown in the graph of FIG. 2 regardless of the position of the listener.
여기서 본 고안의 주요부로 사용되는 반구형 진동판(4)은 그 재질에 있어서 특히 중요성이 요구되는바, 그 재질로써는 공기 저항을 충분히 이길 수 있는 강도 및 탄력을 겸비한 펄프지나 비닐계 합성수지인 폴리플로필렌(p.p)이 가장 이상적이다. 만약 저음역용 스피커(WOOFER)에 고음역용스피커(TWeeter) 또는 중간음역용스피커(MID RANGE)에서 사용되고 있는 천으로 된 진동판을 사용하게 되면 공기를 밀어내는 강도가 불균일하여 우파특성을 잃어버리게되는 문제점이 발생하여 사용할 수가 없는 것이다.Here, the hemispherical diaphragm 4 used as the main part of the present invention is particularly important in its material, and as the material, polyflofilene which is a pulp or vinyl-based synthetic resin having strength and elasticity that can sufficiently overcome air resistance. pp) is the most ideal. If you use cloth diaphragm which is used in TWeeter or MID RANGE for low frequency speaker (WOOFER), there is a problem that the right to push the air is uneven and the right wave characteristic is lost. It can't be used.
한편 본 고안은 제 1 도와 같이 반구형의 진동판(4) 내로 모든 스피커 본체를 집어넣을수가 있어 그 부피를 최소화하여 콤팩트한 저음역용 스피커를 제공할 수가 있는 것이다.On the other hand, the present invention can put all the speaker body into the hemispherical diaphragm 4 as in the first diagram it is possible to provide a compact low-range speaker by minimizing its volume.
이와같이 본 고안은 드라이브콘(5)으로 연결되는 진동판(4)을 반구형(도움형)으로 구성하여 종래의 콘형 스피커에 평면 진동판을 설치한 저음역용 스피커보다 청취자의 듣는 위치에 관계없이 스피커에서 전달되는 음의 세기가 거의 일정한 무제한 지향성을 갖는 저음역용 스피커로서 그 실사용가치를 일층 고양시킨 콤팩트화가 가능한 우수한 고안인 것이다.In this way, the present invention is composed of a diaphragm (4) connected to the drive cone (5) in a hemispherical shape (help type) is transmitted from the speaker regardless of the listening position of the listener than the low-end speaker installed a flat diaphragm in the conventional cone-shaped speaker It is a low-end speaker with unlimited directivity with almost constant sound intensity, and it is an excellent design that can be compactized to further enhance its practical value.
