Abstract
이 발명은 스피커의 음압왜곡 보상장치에 관한 것으로서, 하부판상단의 포올캡에서 교류자속의 상쇄를 위한 유도전류가 이론적으로 90°의 시간적 위상차만을 갖게 됨으로써 상쇄효과가 불완전하고(180°가 완전함), 상부판과 하부판에 유도전류가 발생하여 저항에 인한 열손실(철손)이 발생하였으며, 또한 상, 하부판에 교류자속이 침투하여 히스테리시스(HYSTERISIS) 손실이 발생되는 종래의 문제점을 해결하고자 한다.The present invention relates to a sound pressure distortion compensator of a speaker, and the induction current for canceling alternating magnetic flux in the pole cap on the lower plate has theoretically only a 90 ° time phase difference, so that the offset effect is incomplete (180 ° is perfect). In addition, heat loss (iron loss) due to resistance is generated due to an induced current generated in the upper plate and the lower plate, and also to solve the conventional problem that hysteresis loss occurs due to AC flux penetrating the upper and lower plates.
이를 해결하기 위하여 이 발명은, 구동부의 하부판 상단 외주면에 대략 보이스 코일과 동일한 권선수로 권선되고 반대방향으로 권선된 보상코일을 부착형성함으로써 주파수에 관계없이 교류자속이 상쇄되어 교류자속량이 적게되고, 음압왜곡이 최소화되어 스피커 유니트의 음질향상을 도모할 수 있도록 한 것이다.In order to solve the problem, the present invention, by forming a winding coil of approximately the same number of turns as the voice coil and wound in the opposite direction on the upper peripheral surface of the lower plate of the drive unit, the alternating magnetic flux is canceled regardless of frequency, thereby reducing the amount of alternating magnetic flux. The sound pressure distortion is minimized to improve the sound quality of the speaker unit.
그러므로, 이 발명은 고음질이 요구되는 스피커의 분야에 유용하게 이용된다.Therefore, this invention is usefully used in the field of a speaker where high sound quality is required.
