Abstract
본 고안은 스피커용 혼 구조에 관한 것으로서, 스피커 유니트(1)의 방사구(2)에서 방사된 음파를 음파 분리용 리브(3)에 의해서 상하로 분리하고, 분리된 음파를 단면적이 일정한 음향 통로(4)로 이동시킨 후, 증폭을 위한 음향 통로(5)를 통하여 증폭되고 다시 결합되는 것을 특징으로 한다.The present invention relates to a horn structure for a speaker, which separates sound waves radiated from the radiator port 2 of the speaker unit 1 up and down by a sound wave separation rib 3, and separates the separated sound waves with a constant cross-sectional area. After moving to (4), it is characterized in that it is amplified and recombined through the acoustic passage (5) for amplification.
따라서, 본 발명에서는 구조가 간단하여 조립이 용이할 뿐만 아니라, 스피커 유니트에서 방사되는 단일 음원을 복수의 수직 배열 음원으로 그 특성을 변환시켜서, 결과적으로 음원간의 결합성을 더욱 증대시킴으로서, 특히 같은 구조의 스피커 시스템을 수직으로 여러 대 배열하여 사용하였을 때, 더욱 멀리 소리를 전달할 수 있는 효과가 있다.Therefore, in the present invention, not only is the structure simple and easy to assemble, but also the characteristics of the single sound source radiated from the speaker unit are converted into a plurality of vertically arranged sound sources, and as a result, the coupling between the sound sources is further increased. When multiple speaker systems are arranged vertically, the sound can be transmitted farther.
Description
본 고안은 여러 개의 스피커 시스템을 동시에 사용하였을 때, 보다 멀리 소리를 전달하기 위한 스피커 혼에 대한 것이다. 최근 이를 위해 소리 파장의 1/2 보다 가깝게 음원(스피커 유니트)을 배치하여, 음원들이 서로 결합(커플링)하여 멀리 전달 될 수 있는 라인어레이 방식이 각광을 받는 추세이다. The present invention relates to a speaker horn for transmitting sound farther when using multiple speaker systems simultaneously. Recently, a sound source (speaker unit) is placed closer to 1/2 of the wavelength of the sound, and a line array method in which sound sources can be coupled to each other (coupled) and transmitted far away is in the spotlight.
우퍼 유니트의 경우 재생하는 파장이 길고 유니트 전면 대부분이 울림판이기 때문에, 음원간의 거리를 가깝게 배치하는 것이 용이하다. 하지만 고역대를 담당하는 트위터(컴프레션 드라이버)의 경우 실제 소리가 방사되는 방사구가 유니트 크기에 비해서 매우 작은 것이 일반적이기 때문에, 음원간에 밀접하게 배치하는 것이 어려운 일이다. In the case of a woofer unit, since the wavelength to reproduce is long and most of the front part of the unit is a sounding plate, it is easy to arrange the distance between sound sources close. However, in the case of the tweeter (compression driver) in charge of the high frequency, it is difficult to arrange the sound source closely between the sound sources since it is common that the actual radiator emitter is very small compared to the unit size.
결과적으로 스피커 혼을 이용하여 방사면의 크기를 키워줘야 하지만, 혼으로 확장된 방사면에서 방사되는 음원끼리는 음파의 간섭이 발생하여, 음파가 멀리 전달하는데 방해 요소가 된다. 종래에는 이를 해결하기 위해서 유니트에서 발생하는 음파를 평면파로 바꿔주는 스피커 혼들이 개발되어 사용되고 있지만, 평면파로 바꾸기 위한 혼의 구조가 매우 복잡할 뿐만 아니라 평면파로 바뀐 음파는 날카롭고 차가운 특성을 가진다는 등의 문제들이 있다.As a result, the size of the radiation plane should be increased by using the speaker horn, but sound sources radiated from the radiation plane extended to the horn generate interference of sound waves, which prevents the sound waves from transmitting far away. Conventionally, to solve this problem, speaker horns have been developed and used to convert sound waves generated from the unit into plane waves. However, the structure of the horns for converting into plane waves is very complicated and the sound waves converted into plane waves have sharp and cold characteristics. There are problems.
상술한 바와 같이 종래 기술의 문제점을 해결하기 위하여 안출된 본 고안은 보다 간편한 구조로 음원간의 간격을 줄여서, 스피커 유니트에서 방사된 음원을 점음원에서 선음원에 가깝게 만들 수 있는 혼 구조를 제공하는데 그 목적이 있다.The present invention devised to solve the problems of the prior art as described above provides a horn structure that can make the sound source radiated from the speaker unit closer to the line sound source from the point sound source by reducing the interval between sound sources with a simpler structure. There is a purpose.
상술한 목적을 실현하기 위한 본 고안에 의한 스피커용 혼 구조는, 스피커 유니트(1)의 음파 방사구(2)에서 방사되는 음파를 음원 분리용 리브(3)와 혼 측판(12), 혼 상하판(11)에 의해서, 두 갈래의 독립된 음향통로(4)로 분리하고, 분리된 두 개의 음원은 일반적인 방사구조의 형상인 음향통로(5)를 거치면서 증폭된 소리로 혼 밖으로 방사되는 구조를 특징으로 한다.The speaker horn structure according to the present invention for realizing the above-described object, the sound wave radiated from the sound wave radiator 2 of the speaker unit 1, the sound source separation rib 3 and the horn side plate 12, the horn up and down The plate 11 separates the two separate sound paths 4 into two separate sound sources, and the two separate sound sources are radiated out of the horn by the amplified sound through the sound path 5 which is a general radial structure. It features.
따라서 본 고안에서는 구조가 간단하여 조립이 용이할 뿐만 아니라 스피커 유니트에서 방사되는 음파를 효과적으로 수직배열하여 선음원의 특성을 얻을 수 있게 되는 효과가 있다.Therefore, in the present invention, the structure is simple and easy to assemble, and the sound waves radiated from the speaker unit can be effectively vertically arranged to obtain the characteristics of the line sound source.
이하 본 고안의 바람직한 실시예를 첨부된 도면에 따라서 더욱 상세하게 설명하고자 한다.Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
도면 1은 두개의 대칭인 혼부재를 결합하여 완성된 모습을 나타낸다. 스피커 유니트 결합판(14)은 스피커 유니트과 면대면으로 맞닿게 되고, 결합판의 고정홀(9)와 유니트의 고정홀(10)을 나사를 이용하여 조립하도록 되어 있다.1 shows a completed state by combining two symmetric horn members. The speaker unit coupling plate 14 is brought into contact with the speaker unit on a face-to-face surface, and the fixing holes 9 of the coupling plate and the fixing holes 10 of the unit are assembled using screws.
두개의 대칭 혼부재는 상호 결합홀(8)에 의해서 상호 나사로 체결하도록 되어 있다.The two symmetric horn members are fastened to each other by mutual coupling holes 8.
음파방사구(2)에서 방사되는 음파는 음향 통로(4)에 의해서 수직으로 나뉘어 지는데, 이 음향 통로(4)는 각 단면에서 동일한 면적으로 형성되어 음파의 특성이 변하지 않도록 한다. 분리된 음파는 2차 음향 통로(5)로 유입되어 그 단면을 넓히면서 수직적으로 일정한 지향각을 형성하면서 증폭된다.The sound waves radiated from the sound wave radiator 2 are divided vertically by the sound passages 4, which are formed in the same area in each cross section so that the characteristics of the sound waves do not change. The separated sound waves are introduced into the secondary sound passage 5 and are amplified while forming a constant directivity vertically while widening the cross section thereof.
음파가 서로 간섭을 일으키지 않고 결합하기 위해서는 파장의 1/2 이하로 음원의 거리가 가까와야 하는데, 혼 크기가 커져야 할 경우에는 도면 2의 또다른 실시예처럼 음원 분리용 리브(3)을 추가로 확장하여 음파의 결합성을 유지할 수 있다.In order to combine the sound waves without interfering with each other, the distance of the sound source should be close to 1/2 or less of the wavelength. If the horn size needs to be increased, the ribs 3 for sound source separation may be additionally added as shown in another embodiment of FIG. It can be expanded to maintain sound wave coupling.
도면 1과 같이 결합된 스피커 혼 조립품은 도면 3과 같이 스피커 인클로저에 조립될 수 있다. 인클로저에 장착을 위한 결합판(6)에는 결합홀(7)이 형성되어 있어서, 인클로저의 결합판(20)에 나사로 체결한다. 인클로저 장착을 위한 결합판(6)은 혼의 중간부에서부터 돌출되고, 보강판(13)에 의해서 지지되어 스피커 유니트의 무게를 충분히 감당하도록 형성되어 있다.The speaker horn assembly coupled as shown in FIG. 1 may be assembled into a speaker enclosure as shown in FIG. A coupling hole 7 is formed in the coupling plate 6 for mounting to the enclosure, so that the coupling plate 6 is screwed to the coupling plate 20 of the enclosure. The coupling plate 6 for mounting the enclosure protrudes from the middle of the horn and is supported by the reinforcement plate 13 so as to sufficiently bear the weight of the speaker unit.
음향 통로(5)의 마지막단에서 방사된 음파는 인클로저에 설치된 음파 방사판(22)에 의해서 수평으로 확산하도록 되어 있다.The sound waves radiated at the end of the acoustic passage 5 are horizontally diffused by the sound wave radiating plate 22 provided in the enclosure.
상술한 바와 같은 본 고안에 의하면 구조가 간단하여 조립이 용이할 뿐만 아니라 스피커에서 방사되는 음파를 효과적으로 수직적 배열로 변환시킴으로써, 음파간의 간섭을 줄이고 고음질의 음파를 보다 멀리 전달하는 음향적 특성을 얻을 수 있다..According to the present invention as described above, the structure is simple and easy to assemble, and by converting the sound waves radiated from the speaker into a vertical array effectively, it is possible to reduce the interference between the sound waves and to obtain acoustic characteristics that deliver higher quality sound waves farther. have..
