It is.

첨부도면 제1도는 고음스피커(13), 중음스피커(14), 저음 스피커(15)등 3개의 스피커를 가진 스피커 시스템의 일예를 나타낸 사시도로서 각 스피커(13)(14)(15)는 하나의 스피커 캐비넷(19)에 함께 부착되어 있다.1 is a perspective view showing an example of a speaker system having three speakers, such as the treble speaker 13, the mid-speaker 14, and the bass speaker 15, wherein each speaker 13, 14, 15 is a single speaker. It is attached to the speaker cabinet 19 together.

또 상기 구조에서는 더 많은 수의 스피커가 설치되는 경우에도 스피커를 동일한 배플(Baffle)에 부착할 수밖에 없다.In the above structure, even when a larger number of speakers are installed, the speakers have to be attached to the same baffle.

그러나 상기한 스피커 시스템은 스피커가 모두 한 방향으로만 향하여 있기 때문에 디자인이 단조롭고 사용자의 취향이나 주위여건에 따라 음역별로 스피커의 방향을 조절 할 수 없는 결점이 있다.However, the speaker system has a drawback in that the speaker is all oriented in one direction, so the design is monotonous and the direction of the speaker cannot be adjusted by sound range according to the user's preference or ambient conditions.

또 제2도와 같이 하나의 스피커(13)(통상 고음스피커임)를 별도의 스피커 캐비넷(20)에 부착하고 이를 중음스피커(14)와 저음스피커(15)가 부탁된 스피커 개비넷(21)에 얹어놓을 수 있게한 스피커 시스템이 알려져 있으나, 각 스피커 캐비넷 사이에 결합수단이 없어 상방에 얹혀진 스피커 캐비넷이 바닥면으로 낙하될 우려가 있고 상부 스피커의 방향전환 작동이 불안정한 결점이 있다.In addition, as shown in FIG. 2, one speaker 13 (usually a high-pitched speaker) is attached to a separate speaker cabinet 20, and the mid-range speaker 14 and the bass speaker 15 are attached to the speaker cabinet 21 to which the speaker is requested. There is a known speaker system that can be mounted, but there is a risk that the upper speaker cabinet may fall to the floor because there is no coupling means between each speaker cabinet, and the redirection operation of the upper speaker is unstable.
