Summary:Provided is a slit-firing type speaker device which can play back full band. The speaker device comprises: a speaker unit configured to generate sound; an enclosure in which the speaker unit is installed and which is provided to block a rearward sound of the speaker unit so that the rearward sound does not mix with a forward sound; and a reflection plate which covers the speaker unit and is coupled to the enclosure to form a sound passage through which the generated sound moves, wherein the sound passage can comprise: an emitting part which is formed on one end of the sound passage and from which the generated sound is emitted; and an opening part which is formed on the other end of the sound passage. L'invention concerne un dispositif de haut-parleur de type à émission par fente pouvant jouer pleine bande. Le dispositif de haut-parleur comprend : une unité de haut-parleur configurée pour générer un son; une enceinte dans laquelle l'unité de haut-parleur est installée et qui est prévue pour bloquer un son arrière de l'unité de haut-parleur de telle sorte que le son arrière ne se mélange pas avec un son avant; et une plaque de réflexion qui recouvre l'unité de haut-parleur et est couplée à l'enceinte pour former un passage sonore à travers lequel le son généré se déplace, le passage sonore pouvant comprendre: une partie d'émission qui est formée sur une extrémité du passage de son et à partir de laquelle le son généré est émis; et une partie d'ouverture qui est formée sur l'autre extrémité du passage de son. 전(全) 대역 재생이 가능한 틈 방사(slit-firing)형 스피커 장치를 제공한다. 스피커 장치는, 소리를 생성하도록 구성되는 스피커 유닛과, 상기 스피커 유닛이 장착되고, 상기 스피커 유닛의 후방음이 전방음과 섞이지 않도록 상기 후방음을 차단하도록 마련되는 인클로저 및 상기 스피커 유닛을 커버하고, 상기 인클로저와 결합하여 상기 생성된 소리가 이동하는 음향 통로를 형성하는 반사판을 포함하고, 상기 음향 통로는, 상기 음향 통로의 일단에 형성되고, 상기 생성된 소리가 방사되는 방사부와, 상기 음향 통로의 타단에 형성되는 개구부를 포함할 수 있다.
