说起来,扬声器的工作原理很简单。无非是通电的音圈在磁场中运动,带动振膜振动辐射出声波。可是,一只扬声器却是多种工业和技术的产物。一个世纪以来,耗费了许多人力和物力进行多方面研究,结果也没取得什么飞跃的进展。直到今天,人们还不能光凭物理测 Speaking, the working principle of the speaker is very simple. Nothing more than the power of voice coil movement in the magnetic field, vibrating diaphragm vibration radiation sound waves. However, a speaker is a product of a variety of industries and technologies. Over the past century, many human and material resources have been spent on various aspects of research, and no progress has been made. Until today, people still can not rely on physical measurements
