Abstract

본 발명은 스피커구동장치에 관한 것으로서, 특히 스피커보빈의 여러 부분에 권취된 보이스코일들과 이 보이스코일에 대응하여 자기장을 유도하는 스피커자기계의 다중자기회로를 구비한 다중스피커구동장치에 관한 것이다. 스피커구동장치의 자기회로 중 한 개의 자기회로는 원통형보빈의 내주부의 원주형마그네트와 삽입자기유도판으로 형성된 내부자기계와 외주부의 환형마그네트와 환형자기유도판으로 형성된 외부자기계로 구비된다. 이 하나의 자기회로가 원통형보빈에 권취된 보이스코일의 개수만큼 적층되어 다중구조의 자기회로를 형성함으로써 원통형보빈의 상한 진동력을 증가시킨다. 이로인해, 스피커 구동시, 저음의 재생범위가 넓어지는 효과를 가지며 각 보이스코일에 작용하는 자기력의 간섭에 의해 중고음재생시 발생하는 분할진동을 억제하여 중음을 안정화시키고 불필요한 고음을 제거하는 효과를 갖는다.Field of the Invention [0002] The present invention relates to a speaker driving apparatus, and more particularly, to a multi-speaker driving apparatus having a multi-magnetic circuit of a speaker magnet that induces a magnetic field corresponding to voice coils and voice coils wound around various portions of a speaker bobbin. One of the magnetic circuits of the speaker drive apparatus is provided with an insulator machine formed by a cylindrical magnet of an inner peripheral portion of the cylindrical bobbin and an insertion magnetic induction plate, and an external magnetic system formed by an annular magnet of an outer peripheral portion and an annular magnetic induction plate. This one magnetic circuit is stacked by the number of voice coils wound on the cylindrical bobbin to form a multi-structure magnetic circuit, thereby increasing the upper vibration power of the cylindrical bobbin. This has the effect of widening the reproduction range of the bass sound when the loudspeaker is driven and has the effect of stabilizing the middle sound and eliminating unnecessary treble by suppressing the divided vibration generated at the time of reproduction of the middle tone due to the interference of the magnetic force acting on each voice coil .
