  • Previous iMacs featured a dual-mic setup, with two microphones hiding behind the front-facing camera. Two microphones allows the device to filter out ambient noise and produce a cleaner signal.

  • This year, it seems Apple switched to a single microphone—and moved it to the bottom of the display, behind the glass.

  • Perhaps they've improved their signal processing enough to make do with one and save some pennies.

  • We'll wait to hear from the early adopters if the new setup is any better or worse.

之前的 iMac主打双麦克风设计，即将两个麦克风藏在前部摄像头后面。两个麦克风将可以滤除周围的环境噪音，以打造纯净的音质。

今年，Apple 似乎改用了单麦克风设计，并将它移至玻璃面板底下、显示器的下方。

也许，Apple 改进了信号处理，以期用最少的钱达到双麦克风的效果。

请较早入手新 iMac 的用户向我们反馈你们对单麦克风设计的看法，我们将洗耳恭听。
