자외선경화 접착제를 이용한 보이스코일 제조방법{METHOD OF MAKING VOICE COIL WITH ULTRAVIOLET ADHESIVES}VOICE COIL MANUFACTURING METHOD USING UV CURIZED ADHESIVE {METHOD OF MAKING VOICE COIL WITH ULTRAVIOLET ADHESIVES}

본 발명은 스피커용 보이스코일에 관한 것으로, 더욱 상세하게는 자외선경화(UV) 접착제를 이용한 보이스코일 제조방법에 관한 것이다.
The present invention relates to a voice coil for a speaker, and more particularly, to a voice coil manufacturing method using an ultraviolet curing (UV) adhesive.

일반적으로, 널리 사용되는 다이나믹 방식 스피커는 영구자석과 보이스 코일, 그리고 보이스 코일의 움직임에 따라 진동하는 진동판으로 이루어져, 보이스 코일에 전류가 흐르면 영구자석에 의해 형성된 자기장과의 상호작용에 의하여 보이스 코일이 움직이게 되며, 이때 보이스 코일의 움직임에 따라 진동판이 진동하게 되어 소리를 발생시키게 된다. In general, a widely used dynamic speaker includes a permanent magnet, a voice coil, and a diaphragm vibrating according to the movement of the voice coil. When a current flows through the voice coil, the voice coil is formed by interaction with a magnetic field formed by the permanent magnet. In this case, the diaphragm vibrates according to the movement of the voice coil to generate sound.

통상, 콘 스피커의 경우에는 코일을 보빈에 권선하여 보이스코일을 제조한 후 보빈을 진동판에 부착하나 마이크로 스피커의 경우에는 보빈을 사용하지 않고 미리 접착층이 도포된 와이어를 사용하여 권선한다. 예컨대, 대한민국 특허청 등록특허공보에 등록번호 제10-0968292호로 공고된 보이스코일 제조방법 및 장치는 수작업으로 이루어지던 보이스코일의 리턴 작업과 연결선 접착 작업을 자동화 공정으로 처리하는 기술이 개시되어 있다.In general, in the case of a cone speaker, a coil is wound around the bobbin to manufacture a voice coil, and then the bobbin is attached to a diaphragm, but in the case of a micro speaker, the coil is wound using a wire coated with an adhesive layer in advance without using a bobbin. For example, a method and apparatus for manufacturing a voice coil, which is disclosed in Korean Patent Application Publication No. 10-0968292, discloses a technique for processing a return operation of a voice coil and a connection line bonding operation, which were performed manually, by an automated process.

상기 보이스코일은 2개 이상의 와이어가 병렬로 배치되어 UV 접착제로 부착된 것이다.
The voice coil has two or more wires arranged in parallel and attached with UV adhesive.

본 발명에 따르면, 접착층이 미리 도포된 와이어를 사용하지 아니하고 권선 중에 자외선경화(UV) 접착제를 도포한 후 권선하면서 자외선을 조사하여 경화시킴으로써 제조비용을 줄일 수 있고, 열에 강하고 충격에 대한 내구성이 뛰어난 보이스코일을 제조할 수 있다.
