본 고안은 어느 일정대역의 음장(음의 영역)을 향상시킬 수 있도록 한 개량 스피커에 대한 것이다.The present invention is directed to an improved speaker capable of improving the sound field (sound range) of a certain band.

종래의 스피커는 통상 제3도에서 보는 바와같은 구조로 된 것이 널리 사용되었는데, 이들은 각기 제조에 많은 어려움이 있었으며, 특히 특성에서도 음질등이 현저하게 떨어지는 등의 결함이 있었다.Conventional speakers are generally used in the structure as shown in Figure 3, they have been a lot of difficulties in manufacturing, respectively, in particular, there was a defect such as a significant drop in sound quality, such as characteristics.

즉, 제3도 (a)와 같은 스피커의 경우는 일반적인 위상 반전형 스피커로서 캐비네트의 내부와 외부의 음파가 닥트(D)의 크기와 길이에 의해 간섭 또는 증가되는 현상을 이용토록 한 것이지만 제조가 어렵고, 캐비네트는 어느 정도 이상의 강도가 요구되며, 통상 스피커의 최저공진 주파수 이하의 재생에만 활용되는 한계성이 있으며, 그 음장특성은 제4도(가)의 곡선과 같다.In other words, the speaker shown in FIG. 3 (a) is a general phase inverted speaker, which uses a phenomenon in which sound waves inside and outside the cabinet are interfered or increased by the size and length of the duct D. The cabinet has a certain strength or more, and there is a limit that is usually used only for reproduction below the lowest resonance frequency of the speaker, and the sound field characteristics thereof are as shown in FIG.

한편, (나)와 같은 스피커는 통상 라디오 카세트 레코오더 또는 텔레비젼등에 사용되는 염가형으로 저음부분에서 특성이 떨어지는 큰 결점이 있는 것으로 그 음장특성은 제4도(나)의 곡선과 같다.On the other hand, a speaker such as (B) is a low-cost type commonly used in radio cassette recorders or televisions, and has a large drawback in that it has low characteristics in the bass portion.

또한, (다)와 같은 스피커는 캐비네트가 밀폐형으로 된 것으로서 캐비네트의 강도가 스피커의 진동에 의해 공진이 일어나지 않을 정도의 강성이 요구되며 제조시 캐비네트의 밀폐가 완전하지 않게 되면 음질이 현저하게 떨어지는 결점이 있기 때문에 제조에 많은 어려움이 따르게 되는 문제점이 있으며, 그 음장특성은 제4도(다)의 곡선과 같다.In addition, the speaker as shown in (c) is a cabinet of a sealed type, the strength of the cabinet is required to be rigid enough that resonance does not occur due to the vibration of the speaker, and the sound quality is remarkable when the cabinet is not completely sealed during manufacture. There is a problem that a lot of difficulties in manufacturing due to the drawback of the fall, the sound field characteristics are the same as the curve of FIG.

따라서, 이들 스피커들은 제조가 어렵고, 어느 한 방향으로의 음방사를 목적으로 할 뿐 이므로 필요한 부분의 일정대역 음장을 향상시키기에는 부족한 결점이 있었다.Therefore, these speakers are difficult to manufacture, and only have the purpose of sound emission in one direction, which is insufficient to improve the constant band sound field of the required portion.

본 고안은 이와같은 점들을 해결하기 위해 캐지네트의 양측면과 배면의 중앙에 각각 음의 방사구를 형성하여 다방향의 일정대역 음장재생을 향상시킬 수 있도록 고안한 것으로 첨부도면에 의거 상술하면 다음과 같다.The present invention is designed to improve the multi-directional constant-band sound field reproduction by forming a negative spinneret in the center of both sides and the rear of the cabinet to solve these points. same.

내면에 스피커(1)를 부착한 버플(2)을 전면에 착설하는 캐비네트(3)의 양측면판(4), (4') 동일위치에는 사각형상으로 방사구(5), (5')를 뚫어 설치하고, 배면판(6)의 중앙부에는 스피커(1)와 동일 위치에 원형의 방사구(7)를 뚫어 설치하여서 된 것이다.Both side plates 4 and 4 'of the cabinet 3 on which the baffle 2 with the speaker 1 attached to the inner surface is mounted on the front surface, and the radiating openings 5 and 5' in the same position. The hole is installed, and the central portion of the rear plate 6 is installed by drilling a circular spinneret 7 at the same position as the speaker 1.

미설명 부호 "8"은 버플을 고정하기 위한 리브들이다.Reference numeral "8" is ribs for fixing the baffle.

이와같이 되는 본 고안은 캐비네트(3)의 전면에 스피커(1)를 부착한 버플(2)을 결착하면 제2도에서 보는 바와 같이 스피커(1)의 후면 일부가 배면판(6)의 방사구(7)를 관통되게 결합되는 것으로서, 스피커(1)를 작동시키면 스피커(1)의 진동판에서 발생한 음파는 스피커(1)의 전면과 배면에 동일한 량으로 방사되는데, 이때 배면으로 방사되는 음파는 통상 캐비네트(3) 내에서 제1반사, 제2반사 ……를 계속하게 되어 어느 한 부분으로 모이게 되어, 정재파(定在波)가 발생되며, 그 모이는 부분은 대개 구석진 곳으로 정재파가 모인 부분은 음압이 상승하게 되어 밸런스를 깨뜨리게 됨은 물론 스피커 진동판의 진동에 악 영향을 주게 되지만 본 고안은 상기 정재파가 모이게 되는 구석진 곳에 해당하는 스피커(1)의 후면위치와 캐비네트(3)의 양측 위치에 방사구(7), (5), (5')를 각각 뚫어 설치하였기 때문에 이들 방사구를 통해 정재파가 신속하게 외부로 방사제거 되기 때문에 이들 방사구를 통해 정재파가 신속하게 외부로 방사제거되기 때문에 스피커(1)의 진동판 동작에 악 영향을 주지않게 됨도 물론 결국 음파가 캐지네트(3)의 전면과 후면은 물론 그 양측면으로 동시에 방사되어 넓은 범위의 높은 음장 재생효과를 얻을 수 있게 되는 것이며, 그 음장 특성은 제4도(라)의 곡선과 같다.When the baffle 2 having the speaker 1 attached to the front of the cabinet 3 is attached to the present invention, as shown in FIG. 2, a part of the rear surface of the speaker 1 is radiated from the rear plate 6. When the speaker 1 is operated, the sound waves generated from the diaphragm of the speaker 1 are radiated in the same amount to the front and the rear of the speaker 1, wherein the sound waves radiated to the back are normally First reflection, second reflection in cabinet 3... … As a result, the standing wave is gathered into one part, and the standing wave is generated, and the gathering part is usually a corner, and the part where the standing wave is gathered increases the sound pressure, which breaks the balance as well as the vibration of the speaker diaphragm. Although adverse effects are affected, the present invention provides the spinnerets 7, 5, and 5 'at the rear positions of the speakers 1 and the sides of the cabinet 3 corresponding to the corners where the standing waves are collected. Since the standing waves are radiated to the outside quickly through these spinnerets because they are drilled and installed, the standing waves are quickly radiated to the outside through these spinnerets. Eventually, the sound waves are radiated simultaneously to the front and rear of the cabinet 3 as well as to both sides thereof to obtain a wide range of high sound field reproduction effects. The surname is like the curve in Fig. 4 (D).

특히, 캐비네트(3)의 배면판(6)에 뚫은 방사구(7)에는 스피커(1)의 후면 일부가 관통되게 결합되기 때문에 더욱 진동판의 움직임이 원활하게 되는 것이다.In particular, the part of the rear surface of the speaker 1 is coupled to the spinneret 7 drilled on the rear plate 6 of the cabinet 3 so that the movement of the diaphragm becomes smoother.

이와같이 본 고안은 캐비네트의 양측면과 배면에 방사구를 뚫어 설치하므로 음파가 캐비네트 내부에서 반사되어 일어나던 정재파를 신속하게 외부로 방사 제거시켜 주어 진동판의 움직임을 원활하게 하여주는 장점이 있음은 물론 넓은 범위의 높은 음장 재생효과를 얻을 수 있게 되는 매우 효과적인 고안이다.In this way, the present invention is installed by drilling the spinneret on both sides and the rear of the cabinet, so that the sound waves are reflected from the inside of the cabinet to remove the standing wave quickly radiate to the outside has the advantage of smooth movement of the diaphragm of course It is a very effective design that can achieve a wide range of high sound field reproduction effects.
