본 고안은 소형라디오 카셋트와 같이 스피커박스의 용적이 작은 스피커에 저음 재생 한계를 높이기 위한 저음 보상용 스피커장치에 관한 것이다.The present invention relates to a speaker device for compensating bass for increasing the bass reproduction limit to a speaker of a small volume of a speaker box, such as a small radio cassette.
종래의 라디오 카셋트에 있어서의 스피커장치는 제품의 특성상 크기의 제약을 받기 때문에 용적이 작게되며, 이러한 작은 스피커장치에서는 저역 재생 한계를 높이려 해도 용적이 작은 스피커박스에서는 스피커 자체를 저역특성이 좋은 것으로 사용한다 하더라도 저역 재생특성에는 거의 영향을 주지못하여 스피커용적에 의해 좌우되는 결점이 있었으며, 또한 스피커의 진동판이 울릴 때 진동판의 앞면과 뒷면 양쪽으로 음이 방사되게 되는데 이때 각각의 위상이 반대가 되므로 앞면의 소리는 뒷면의 소리에 영향을 받아 감쇠된 효과가 나며 이는 파장이 긴 저역주파수일수록 더욱 심하여 메인앰프에서 저역을 살려 스피커를 통해 나온다 하더라도 스피커 장치구조상 저역감쇠 현상이 발생하는 문제점이 있었다.The speaker device in the conventional radio cassette is limited in size due to the characteristics of the product, so the volume is small. In such a small speaker device, even if the low frequency reproduction limit is increased, the speaker itself may have good low-frequency characteristics. Even if it is used, it has little effect on the bass reproducing characteristics and is influenced by the volume of the speaker. Also, when the diaphragm of the speaker rings, the sound is radiated to both the front and rear sides of the diaphragm. The sound of the sound is attenuated by the influence of the sound on the back, and the longer the lower the frequency, the more severe the low frequency in the main amplifier, even if coming out through the speaker, there was a problem that the low frequency attenuation occurs in the speaker device structure.
본 고안은 이와같은 제결점을 해결하기 위하여 처음 스피커가 설치된 일측에 터보관(저음 보상용관)을 설치하여 중음 이하의 저음재생효과를 높일 수 있도록 안출한 것으로써 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to solve the above drawbacks by installing a turbo tube (bass compensation tube) on the side where the first speaker is installed to increase the bass reproduction effect below the mid-tone, which will be described in detail with the accompanying drawings. As follows.
스피커박스(1)의 전면 중앙부 상하에는 고음용 스피커(2)와 저음용 스피커(3)를 설치하고, 저음용 스피커(3) 일측에는 터보관(4)을 설치하며, 스피커박스(1)의 후면에는 횡으로 수개의 통공(5)을 형성하여서 구성된 것이다.A high-pitched speaker (2) and a low-pitched speaker (3) are installed above and below the front center of the speaker box (1), and a turbo tube (4) is installed at one side of the low-pitched speaker (3). It is configured by forming a plurality of through holes (5) on the rear side.
이와같이 구성된 본 고안은 제5도의 회로도에서 도시한 바와같이 스위치(S1)을 ON 시키면 R-C 공진회로가 형성되어 고주파수 성분이 중단되어 전체적으로 저역이 승압된 주파수 성분이 메일앰프를 통하여 저음용 스피커(3) 출력으로 나오게 된다.In this configuration, as shown in the circuit diagram of FIG. 5, when the switch S 1 is turned on, an RC resonant circuit is formed so that a high frequency component is interrupted, and a low frequency boosted component is used for the low-frequency speaker (3). ) Output.
이 출력이 저음용 스피커(3)의 진동판(301)을 울려주면 진동판(301) 뒷면으로 발생되는 갖가지 주파수 성분은 스피커 박스(1) 뒷면에 형성된 통공(5)으로 빠져나가게 되는데 이 주파수 성분중 파장이 긴 저주파 성분은 통공(5)으로 빠져나가기 어려우므로 스피커박스(1) 내에서 반사작용이 일어나 터보관(4)을 통하게 된다.When this output echoes the diaphragm 301 of the woofer 3, various frequency components generated on the rear surface of the diaphragm 301 are released to the through hole 5 formed on the rear side of the speaker box 1. Since the long low frequency component is hard to escape to the through hole 5, reflection occurs in the speaker box 1 and passes through the turbo pipe 4.
이때, 터보관(4)의 길이에 따라 매칭되는 주파수 성분은 진폭이 작기 때문에 비 직선성에 따르는 혼변도 일그러짐 및 도플러효과에 의한 주파수 변조의 일그러짐이 작아져 중음이하의 음이 강하게 재생되는 특징을 지닌 것이다.At this time, since the frequency component matched according to the length of the turbo tube 4 is small in amplitude, the distortion of the confusion caused by the nonlinearity and the distortion of the frequency modulation due to the Doppler effect are reduced, so that the sound of the subtone is strongly reproduced. will be.
