본 고안은 조립공정이 극히 간편하도록 구성된 확성기용 드라이버 유니트에 관한 것이다.The present invention relates to a driver unit for a loudspeaker configured to make the assembly process extremely simple.
일반적으로 확성기용 드라이버 유니트는 원기둥 형상의 요크(Yoke)와 도우넛 형상의 마그네트(Magnet) 및 보이스 코일(Voice Coil)이 권회된 진동판으로 구성되어 있고 요크의 외경과 마그네트의 내경사이에는 진동판의 보이스코일 부분이 진퇴할 수 있는 좁은 간격의 공간부가 형성되어 있으며, 이러한 공간부는 진동판의 진퇴시 보이스코일 부분이 요크나 또는 마그네트 부분에 접촉되지 않도록 전체적으로 일정한 간격을 유지하는 것이 중요하다.In general, a loudspeaker driver unit is composed of a cylindrical yoke, a donut-shaped magnet and a voice coil wound around a diaphragm, and between the outer diameter of the yoke and the inner diameter of the magnet, the voice coil of the diaphragm. A narrow spaced portion is formed so that the portion can move back and forth, and it is important to maintain a constant space as a whole so that the voice coil portion does not come into contact with the yoke or the magnet portion when the diaphragm moves forward and backward.
그러나 종래의 드라이버 유니트는 공간부를 형성하기 위해 요크의 바깥둘레에 센터 게이지(Center guage)라 불리는 별도의 기구를 끼우고 그 게이지의 바깥둘레에 마그네트를 끼워 접착제로 고정시킨후 게이지를 빼내어 게이지의 두께만큼 공간부가 형성되도록 하는 구조로 되어 있기 때문에 제조공정중 많은 양의 게이지가 필요하게 되고 마그네트가 접착제에 의해 완전히 고정될때까지 게이지가 요크와 마그네트 사이에 끼워져 있어야 하므로 작업능률의 저하는 물론 공정상의 부주의로 인해 불량품이 많이 발생하게 되는등 결점이 있었다.However, in the conventional driver unit, a separate mechanism called a center gauge is mounted on the outer circumference of the yoke to form a space, and a magnet is fixed to the outer circumference of the gauge to remove the gauge, thereby removing the gauge thickness. As the structure is designed to form the space part, a large amount of gauge is required during the manufacturing process, and the gauge must be sandwiched between the yoke and the magnet until the magnet is completely fixed by the adhesive. There was a defect such as a lot of defective products are generated.
본 고안은 종래의 이와같은 결점을 해결하기 위해 요크와 마그네트 사이에 합성수지로 된 간격유지구를 끼우고 그 상방에 도우넛형의 링과 상판을 결합하므로서 별도의 센터게이지 없이도 유니트를 간편하게 조립할 수 있도록 함은 물론 일정한 간격의 공간부가 형성될 수 있도록 한 것인바 이를 첨부된 도면에 의해 그 구조를 더욱 상세히 설명하면 다음과 같다.In order to solve the above-mentioned drawbacks, the present invention inserts a synthetic resin gap retainer between the yoke and the magnet and combines the donut-shaped ring and the upper plate on the upper side so that the unit can be easily assembled without a separate center gauge. Of course, it is to be formed a space portion of a predetermined interval will be described in more detail the structure by the accompanying drawings as follows.
요크(1)의 외측에 도우넛형의 마그네트(2)를 고정설치하여서 되는 통상의 것에 있어서, 요크(1)와 마그네트(2) 사이에 단턱(3a)을 가진 합성수지제 간격유지군(3)를 끼워 단턱(3a)이 마그네트(2)에 얹혀지도록 하고 간격유지구(3)의 내주벽(3b)과 외주벽(3c)에는 각각 상판(4)의 요입부(4a)와 도우넛형링(5)의 요입부(5a)를 삽입한후 상판(4)과 링(5)사이 공간부(6)에 진동판(7)의 보이스코일 권회부(7a)가 삽입되도록 하여서 된 것이다.In a conventional thing in which the donut-shaped magnet 2 is fixedly installed on the outside of the yoke 1, a gap between the yoke 1 and the magnet 2 is made of a synthetic resin gap holding group 3 having a step 3a. The step 3a is placed on the magnet 2, and the inner peripheral wall 3b and the outer peripheral wall 3c of the spacing support 3 are respectively formed of the recessed portion 4a and the donut ring 5 of the upper plate 4, respectively. After the recess 5a is inserted, the voice coil winding 7a of the diaphragm 7 is inserted into the space 6 between the upper plate 4 and the ring 5.
이와 같이 구성된 본 고안은 간격유지구(3)의 단턱(3a)에 마그네트(2)가 얹혀져 있어 요크(1)와 마그네트(2)가 일정한 간격을 유지하게 되고, 또 간격유지구(3)의 내주벽(3b)과 외주벽(3c)에 상판(4)과 링(5)의 각 요입부(4a)(5a)가 끼워져 있어 상판(4) 링(5) 사이공간부(6)가 일정한 간격을 유지하게 되므로 진동판(7)의 진퇴시 보이스코일 권회부(7a)가 상판(4)이나 링(5)과 접촉하지 않게 된다.According to the present invention configured as described above, the magnet 2 is placed on the step 3a of the spacing holder 3 so that the yoke 1 and the magnet 2 maintain a constant spacing, and The recesses 4a and 5a of the upper plate 4 and the ring 5 are fitted to the inner circumferential wall 3b and the outer circumferential wall 3c, so that the space 6 between the upper plate 4 and the ring 5 is constant. Since the voice coil winding part 7a does not come into contact with the upper plate 4 or the ring 5 when the diaphragm 7 is advanced and retracted.
이와 같이 본 고안은 요크(1)와 마그네트(2) 사이에 간격유지구(3)를 끼우고 이 간격유지구(3)의 상방에 상판(4)과 링(5)을 끼우는 극히 간단한 조립공정에 의해 일정한 간격의 공간부(6)를 형성할 수 있게 되므로 별도의 센터게이지를 사용하여 공간부(6)를 형성하던 종래의 것에 비해 조립공정이 간편해지고 따라서 작업능률의 향상을 기할 수 있으며 제품의 불량율을 대폭 감소시킬 수 있는 효과가 있다.In this way, the present invention is an extremely simple assembly process of sandwiching the gap retainer (3) between the yoke (1) and the magnet (2) and the upper plate (4) and the ring (5) to the upper space of the gap retainer (3). Since the space portion 6 can be formed at regular intervals, the assembling process becomes simpler than the conventional one in which the space portion 6 was formed by using a separate center gauge, thus improving work efficiency. There is an effect that can significantly reduce the defective rate of.
