反馈式主动消噪耳机的研制

The Research of Active Noise Cancellation in Headphone with feedback mode

介绍了消噪系统的工作原理,重点对反馈式主动消噪耳机进行了系统设计,通过时电路仿真、电路调试及测试,验证了消噪耳机的实际消噪效果,最后提出了进一步的改进与建议.

The operating principle of a noise-cancelling system is introduced in this paper, and the system scheme of the active noise-cancelling headphone in feedback mode is described in detail. By the circuit simulating debugging and testing, the noise-cancelling effects of the headphone are proved.Atast,some improvements are proposed.
