深圳润科迪电子有限公司于一九九八年成功推出全新概念的DFT(消失真)功率放大器,凭借能显著改善扬声器的运动失真而在功放设计界独树一帜,DFT技术原理已在今年的《电子报》介绍多次,其实质就是在没有给扬声器附加传感器的情况下,通过对扬声器驱动电压、驱动电流、反电动势进行检测、变换,最终由功放主动补偿扬声器的运动失真。从而达到降低系统失真,改善重放效果的目的。该技术由美国引进,在实用的初期遇到过大量问题。因为在音响这个特别的领域,
Shenzhen Run Cody Electronics Co., Ltd. successfully introduced in 1998 a new concept of DFT (disappear true) power amplifier, with significantly improved speaker motion distortion in the amplifier design industry is unique, the principle of DFT technology has been in this year’s “Electronics Newspaper ”introduced many times, its essence is without additional sensors to the speaker case, through the speaker drive voltage, drive current, back-EMF to detect, transform, and ultimately by the amplifier to actively compensate for the speaker motion distortion. So as to achieve the purpose of reducing the system distortion and improving the replay effect. The technology was introduced by the United States and encountered a number of problems early in its useful life. Because in this special area of audio,
