Abstract

본 발명은 듀얼 보이스코일형 스피커 유니트에 관한 것으로, 일반적으로 하나의 스피커유니트(1)로 고음과 저음을 함께 낼 수 있도록 하고자 하는 경우에 상기 스피커유니트(1)를 이루는 센터폴요크(3)의 소정부위에 하나의 보이스코일(10)만 구비되어 있음으로 인해 상기 스피커유니트(1)로부터 좀더 고음과 저음을 세분하여 낼 수 없게되는 문제점을 해소하기 위하여, 일반적인 스피커유니트(1)의 네트워크에 전기적으로 회로연결되어 상기 네트워크로부터 전달되는 전신호에 의해 상기 스피커유니트(1)용 베이스부(14)의 소정부위에 구비되는 제1센터폴요크(15)의 제1보이스코일(16)에 추가형 상기 베이스부(14)의 소정부위에 동일체로 형성되는 제2센터폴요크(17)의 외주면에 소정의 유격을 갖는 제2보이스코일(18)이 끼워지되, 상기 제2보이스코일(18)에 상응하여 상기 베이스부(14)측 반경상의 소정부위에 별도의 마그네트(2)를 갖는 플레이트(4)가 동일체로 형성됨으로써 하나의 스피커유니트(1)로 상기 제1,2보이스코일(16,18)을 통해 고음용 스피커(Tweeter)와 저음용 스피커(Woofer)의 기능을 함께 실현할 수 있게 되는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dual voice coil type speaker unit. In general, when one or more speaker units (1) are capable of producing high and low sounds, the center pole yoke (3) of the speaker unit (1) is formed. Since only one voice coil 10 is provided at a predetermined portion, in order to solve the problem that it is not possible to subdivide more high and low sounds from the speaker unit 1, the network of the general speaker unit 1 is electrically connected. Is connected to the first boy coil 16 of the first center pole yoke 15 provided at a predetermined portion of the base portion 14 for the speaker unit 1 by a circuit signal connected to the circuit. A second boy coil 18 having a predetermined play is fitted to the outer circumferential surface of the second center pole yoke 17 formed in the same position on the predetermined portion of the base portion 14, but the second boy coil 18 is inserted into the second boy coil 18. correspondence For example, the first and second voice coils 16 and 18 may be formed as one speaker unit 1 by forming a plate 4 having a separate magnet 2 at a predetermined radius on the base 14 side. Through this, it is possible to realize the functions of a high-pitched speaker (Tweeter) and a low-pitched speaker (Woofer) together.
