主動式噪音消除耳機 ANC Headphone
指導老師:張政元   組長:簡仲雯   組員:吳星穎
本專題為主動式噪音控制耳機,在耳罩式耳機的耳杯中放入麥克風,透過外接前置放大器與控制器電路產生與噪音相反相位的聲音,在使用耳機功能的同時能對機器、車輛等器械發出的低頻噪音進行消噪,適用於在工地、機場工作的人員,減輕低頻噪音對聽力的影響。
This thesis is a noise cancellation headphone with ANC (Active Noise Cancellation) theorem. Putting a mini microphone in ear-cup, we connect a pre-amplifier, an audio power amplifier, and controller circuit to produce the noise which phase is opposite with original noise. Therefore, through the feedback circuit the noise will eliminate.
When the machines are working, there are some low frequency noise for a long time. The feedback circuit will cancel the low-frequency noise. During using the normal headphone function, the people who working at a noisy environment can using the noise cancelation function to protect their hearing ability at the same time.
我們決定將壓電陶瓷晶片和鞋子做結合。
