CS2.4是THIEL(中译名“超奥”)在2003年推出的产品,它蜕变于1997年推出的CS2.3。 对于如图1所示的同轴单元,THIEL称之为“复合驱动器(Compound Driver)”。它乍看和普通中音单元没什么两样,但它与KEF的双音圈双磁路Uni-Q技术不同,THIEL的这个同轴单元只有一个音圈和一套磁路结构,在中音单元的防尘帽位置上安置了高音的球顶振膜,中音振膜与高音振膜用一种聚合物“耦合悬边”相连接。这一悬边既充当球顶高音的悬挂,又起到机械分频的作用,它将来自音圈波长较大的中频振动通过“耦合悬边”传递到中音锥盆。而那些波长较小的高频被“耦合悬边”阻碍,
CS2.4 is the product of THIEL (Chinese translation of “Super Olympics”) introduced in 2003, it transformed into CS2.3 released in 1997. For the coaxial unit shown in Figure 1, THIEL called the “compound driver.” At first glance, it looks no different from a normal midrange unit, but unlike KEF’s dual voice coil dual magnetic Uni-Q technology, the THIEL coaxial unit has only one voice coil and a magnetic circuit structure. Dust cap placement of the dome of high-pitched diaphragm, midrange diaphragm and treble diaphragm with a polymer “coupled dangling” connected. This dangling serves as both a dome-treble suspension and a mechanical crossover, which transmits mid-frequency vibrations from the larger voice coil through the “coupling dangling” to the mid-cone. While those with smaller wavelengths are hampered by “coupled dangling”
