  • We pull the final board from the top of the Show, and find the expected hardware—buttons, lots of microphones, and some ADCs to funnel your voice from the microphones to the CPU:

  • Texas Instruments TLV320ADC3101 92 dB SNR Low-Power Stereo ADC (x4) as seen in the Echo and Echo Dot

  • Knowles MEMS Microphone (x8)

  • Switch (x3)

  • Fun fact: all that foam tape minimizes vibration noise so that Alexa still has a chance of hearing you during loud music sessions.

我们把最后一块电路板从 Show 的顶部拽出来，然后发现了预料之中的硬件—按键、许多麦克风和一些将你的声音从麦克风传送到CPU的 数模转换器：

Texas Instruments TLV320ADC3101 92 dB SNR 低功率立体声 数模转换器 (x4) ，与 Echo 和 Echo Dot中看到的一样

麦克风 (x8)

开关 (x3)

小知识：泡棉胶带可以减少震动噪音，这样Alexa即使在比较嘈杂的环境也可以听到你说话。
