当代电动式扬声器结构之研究与创新

Research and innovation of modernelectric loudspeaker structure

扬声器仍是当前电声转换最为薄弱的环节,由于失真较大,长期以来电声指标的提高一直受其瓶颈制约。本文从电声理论入手,对其结构进行深入全面地分析与研究,发现“双音效应”;并就声电类比串联电路之误作了大胆地修正。提出创新改革方案:纯音电动式扬声器,它的出现标志着平民高保真音响时代的到来。

Loudspeaker is still the weakest link of electroacoustic conversion,due to the large distortion.The improvement of electroacoustic index has been restricted by its bottleneck for a longtime.This paper starts with the electroacoustic theory;the structure is analyzed and studied thoroughly and comprehensively.We found the“Two tone effect”;in addition,the mistake of the analogy series circuit of acoustic and electric is boldly corrected.Put forward innovation and reform plans,pure tone electric speaker.Its appearance marks the arrival of the era of high fidelity sound for common people.
