| 纯铝带高音的基本结构是铝带悬置于两列磁钢所构成的横向线性磁场中，铝带同时起到两个作用：音圈和振膜。通常铝带自身的阻抗很低，为了与放大器匹配，中间必需插入阻抗变换器把功放输出转化成低电压大电流信号。 The basic structure of pure aluminium belt tweeter is that the aluminium belt is suspended in the transverse linear magnetic field composed of two rows of magnetic steels, and the aluminium belt plays two roles simultaneously: voice coil and vibration film. Usually the impedance of the aluminum strip itself is very low. In order to match the amplifier, it is necessary to insert an impedance converter in the middle to convert the output of the power amplifier into a low voltage and high current signal. |
