본 고안은 스피커를 사용하는 음발생 장치를 구비하는 기기의 스피커 시스템에서 특정 주파수 대역에서 특성을 보정하도록 한것으로서, 특히 공명기의 원리를 이용하여 음의 간섭현상을 배제토록한 장치에 관한 것이다.The present invention aims to correct a characteristic in a specific frequency band in a speaker system of a device having a sound generating device using a speaker, and more particularly, to a device for excluding sound interference by using the principle of a resonator.
종래에는 제1도에 도시한 바와같이 통상 스피커의 앞단에 관형상의 음통로(4)를 형성하는 스피커 캐비넷(1)중앙 내부의 배플(2)에 스피커(3)를 설치하고 후방 캐비넷(1) 하측에 덕트(7)를 형성한 것이다.Conventionally, as shown in FIG. 1, a speaker 3 is provided in a baffle 2 inside the center of a speaker cabinet 1 which forms a tubular sound passage 4 at the front end of a speaker, and the rear cabinet 1 The duct 7 is formed in the lower side.
이와같은 종래의 시피커 시스템에서 보는 바와같이 스피커 캐비넷(1)의 배플(2)에 설치된 스피커(3)에서 음이 발생하여 스피커 앞단 음통로(4)를 통과할 때 음파의 간섭 및 전재파 현상에 의하여 주파수 특성상 음압이 상승하여 제2와 같이 특정 주파수 대역의 음레벨이 피지치를 형성하게 되었다.As shown in the conventional sieppeaker system, sound is generated from the speaker 3 installed in the baffle 2 of the speaker cabinet 1, and the sound wave is interfering with the sound wave interference when passing through the sound path 4 in front of the speaker. As a result, the sound pressure increases due to the frequency characteristics, and the sound level of the specific frequency band forms sebum as in the second embodiment.
또한 스피커(3) 후방 캐비넷(1)에 덕트(7)를 형성하므로 스피커 내부에 음이 방사되므로 스피커 유니트 후방에서 발생하는 음을 캐비넷(1) 내부에서 공명시켜 덕트(7)를 통하여 후방으로 내보내 저음을 재생시킬 수 있는 것이다.In addition, since the duct 7 is formed in the rear cabinet 1 of the speaker 3, the sound is radiated inside the speaker, so that the sound generated from the rear of the speaker unit is resonated in the cabinet 1 and is discharged to the rear through the duct 7. You can play bass.
그러나 이러한 종래의 스피커시스템에서는 스피커에서 음이 발생하여 스피커 앞단 음통로를 통과할 때 음파의 간섭 및 정재파에 의한 영향에 특정주파수에서 음악이 상승하여 제2도의 주파수 특성상에 있어서 특정 주파수 대역에서 음레벨의 피크치가 발생하여 평탄한 특성을 얻기가 아려웠으며, 음파의 간섭현상에 의해 음의 명료도가 뚜렷해지지 못하는 문제점이 있다.However, in such a conventional speaker system, when the sound is generated from the speaker and passes through the sound path in front of the speaker, the music rises at a specific frequency due to the interference of the sound waves and the standing wave, and thus the sound level at a specific frequency band in the frequency characteristic of FIG. It was difficult to obtain a flat characteristic due to the peak value of, and there is a problem that the sound clarity is not clear due to the interference of sound waves.
본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서 스피커에서 음향이 발생하여 스피커 앞단 음통로를 통과할 때 공평기의 원리를 이용 음통로에 구멍을 형성하여 구멍을 통하여 공동에서 특정음대역의 피크치임을 공명 상쇄시켜 음레벨이 평탄한 늑성을 얻도록 하여 음의 명료도가 뚜렷해지도록 하는데 본 고안의 목적이 있다.The present invention was devised to solve the above problems. When the sound is generated from the speaker and passes through the sound path in front of the speaker, the hole is formed in the sound path by using the principle of fairness. The purpose of the present invention is to make the sound clarity clear by canceling the peak value by resonating the sound level so as to obtain flat smoothness.
상기와 같은 목적을 달성하기 위한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment for achieving the above object will be described in detail with reference to the accompanying drawings.
스피커 캐비넷(1) 중앙내부의 배플(2)에 스피커(3)를 설치하고 상기 스피커(3)의 앞단에 관형상의 음통로(4) 외측에 공동(6)을 형성하여 상기 음통로와 공동사이에 덕트(5)를 형성하여 음통로를 통과하는 음파의 공명 현상을 상쇄 시키도록 한 것이다.The speaker 3 is installed in the baffle 2 inside the center of the speaker cabinet 1, and the cavity 6 is formed outside the tubular sound passage 4 at the front end of the speaker 3, and the cavity is connected to the sound passage. The duct (5) is formed between to cancel the resonance of the sound waves passing through the sound path.
도면중 미설명부호 7은 덕트이다.Reference numeral 7 in the drawings is a duct.
이와같이 구성된 본 고안의 작용 효과는 다음과 같다.The effects of the present invention configured as described above are as follows.
스피커 캐비넷(1)의 배플(2)에 설치된 스피커(2)에서 음이 발생하여 스피커 앞단 음통로(4)를 통과할때 음파의 간섭이나 정재파를 방지하기 위하여 헬름홀쯔 공명기 원리를 이용한 덕트(5)를 통하여 공동(6)에 의해 특정 주파수 대역에서 발생되는 음의 피크치에서 발생되는 공명현상을 감쇄 시키게 되는데 이를 수식으로 표현하면여기서 C : 음속(㎝/sec) A : 구멍의 단면적(㎝) L : 구멍의 길이(㎝) V : 공동의 부피(㎠) Duct using the Helmholtz resonator principle to prevent sound waves from interfering or standing waves when the sound is generated from the speaker 2 installed in the baffle 2 of the speaker cabinet 1 and passes through the sound passage 4 in front of the speaker 5 ) To attenuate the resonance generated at the negative peak value generated in a specific frequency band by the cavity (6). Where C: sound velocity (cm / sec) A: cross-sectional area of hole (cm) L: length of hole (cm) V: volume of cavity (cm 2)
상기와 같은 음통로(4)의 내부에 덕트(5)을 통하여 음이 공동(6)에서 흡수하므로 공동내부에서 반사되며 소멸 되므로 시피커(3)에서 발생하는 음이 음통로(4)로 통과할 때 헬름홀쯔 공명기 원리를 이용한 공동(6)에 의해 음파의 간섭이나 정재파가 보정되어 제4도와 같이 평탄한 특정 주파수를 갖는 음이 음통로(4)를 통하여 외부로 음이 발진되는 것이다.Since the sound is absorbed from the cavity 6 through the duct 5 inside the sound path 4 as described above, the sound generated from the sipe picker 3 passes through the sound path 4 because it is reflected and extinguished within the cavity. At this time, the interference or standing wave of the sound wave is corrected by the cavity 6 using the Helmholtz resonator principle, so that the sound having a flat specific frequency as shown in FIG. 4 is oscillated to the outside through the sound path 4.
또한 스피커 캐비넷(1) 후방 덕트(7)에 의해 스피커(3) 내부에서 음이 후방으로 방사되므로 후방에서 발생하는 음의 정재파를 덕트(7)를 통하여 후방으로 내보내 소멸시킬 수 있는 것이다.In addition, since the sound is radiated to the rear from the inside of the speaker 3 by the rear duct 7 of the speaker cabinet 1, the standing wave of the sound generated from the rear can be discharged to the rear through the duct 7 to be extinguished.
상기와 같은 본 고안에 의하면 스피커에서 음향이 발생하여 스피커 앞단 음통로를 통과할 때 공명기의 원리를 이용 관통로 내부의 구멍을 통하여 공동에서 특정음 대역의 피크치음을 상쇄시킴으로서 제4도와 같이 특성이 평탄한 특성을 얻으므로 음파의 간섭을 받지 않아 음의 명료도가 뚜렷해지는 잇점이 있다.According to the present invention as described above, when the sound is generated from the speaker and passes through the sound path in front of the speaker, the characteristics of the characteristic are as shown in FIG. 4 by canceling the peak sound of a specific sound band in the cavity through the hole inside the through passage using the principle of the resonator. Since the flat characteristics are obtained, the sound intelligibility is distinct from the interference of sound waves.
