摘　　要：简述了驱动带式扬声器的工作原理(Lorentz Force洛仑兹力)。并对美国Bohlender Graebener公司的NE08产品作了具体分析,包括尺寸、磁体排列、振膜、音圈圈数分布、有限元法的磁通密度模拟等。最后介绍了这种带式扬声器的频响及失真度。The working principle of driving the ribbon transducer（Lorentz Force） is described. The detailed dimension, magnet array, diaphragm, coil rounds distribution of voice coil for NE08 of Bohlender Graebener from US are analyzed. The finite elements method of magnetic flux simulation is introduced. Finally, the frequency response and very low distortion value of this ribbon transducer are introduced.
