Abstract

구동부의 하부판 상단 외주면에 대략 보이스 코일과 권선수로 권선된 보상용 코일을 구비한 스피커가 개시된다. 이 스피커는 보상코일이 보이스 코일과 반대방향으로 권선되되 보이스 코일과 직렬로 연결되어 주파수에 관계없이 교류자속이 보상코일에 의해 상쇄되어 교류자속량이 적게되고, 음압왜곡이 최소화되어 스피커 유니트의 음질향상을 도모할 수 있도록 구성된다.Disclosed is a speaker having a voice coil and a compensation coil wound by a number of windings on an upper outer circumferential surface of a lower plate of a driving unit. In this speaker, the compensation coil is wound in the opposite direction to the voice coil, but is connected in series with the voice coil so that the AC flux is canceled by the compensation coil regardless of the frequency, so that the amount of AC flux is reduced and the sound pressure distortion is minimized to improve the sound quality of the speaker unit. It is configured to promote.
