It’s been a month or two since Amazon’s release of their attempt at creating a physical competitor to Siri and Cortana. You have undoubtedly read various reviews of it and heard what it does but we haven’t taken a look at what’s making it all tick. The boys and girls at iFixit have managed to get their hands on one and tear it down, let’s check it out.

Amazon Echo Teardown

The Echo promises to be a faithful home companion whether you want cooking instructions or a favorite song played. Part of what makes the Echo a good home companion is the fact that its a good listener. This is due entirely to the seven(!) V6 microphones embedded in and around the LED ring at the top of the device.

Echo also responds in kind due to the 2.0” tweeter and 2.5” woofer which are powered by a Texas Instruments TPA3110D2 15W Filter-Free Class D Stereo Amplifier. Also living on the power and speaker driver board is the Texas Instruments TPS53312 Step-down regulator with integrated switcher with sound processing issued to a Texas Instruments TLV320DAC3203 Ultra Low Power Stereo Audio Codec.

Rounding things out nicely is the LED/Microphone board near the very top of the device. The LED ring that surrounds the top of Echo is powered by four Texas Instruments LP55231 Programmable 9-Output LED Drivers and audio signal processing duties are handled by four Texas Instruments TLV320ADC3101 92dB SNR Low-Power Stereo ADC’s.

Thanks to iFixit’s superb tear down of the Echo we get to see just how much careful thought was put into making the device work flawlessly.
