But only 4 were ultimately required to integrate with the virtual assistant software from Amazon and Google, so not only were the components removed for the production ramp version, but the board was updated to remove the traces and through holes for the version that I opened up on camera. We suspected that originally this board had 6 different microphones because they are clearly labeled on the solder mask. From the different date codes on the boards were pieced together the evolution of the design from its initial production release in 2018 to a revision in 2019. Here we noticed some of the differences between the product in the live teardown and the one captured earlier on the Instrumental platform. Version differences between MIC PCBA from live teardown version and Instrumental pre-teardown version – note the missing “MIC 1” designator and components on the bottom tab of the board. After peeling back the pieces of black tape on the housing, I unfastened 4 screws holding the top housing and microphone board in place. Once the bottom cover was off, I was able to remove the bottom plastic housing and slide off the sheet metal cage surrounding the speaker. These screws had so much threadlock on them that I needed to add a lever arm to my iFixit screwdriver just to get them started.
To get into the product, I pried up the rubber foot and unscrewed 4 rather tight machine screws. While much of the teardown was done live, Tobias also showed off some of the capabilities of the Instrumental system allowing the team to dive deeper into the boards and assemblies. In this episode of Change Notice, ex-Apple engineer Tobias Noonan-Harris and I opened the Sonos One (Gen 2). We chose the Sonos One because it was one of the first independent speaker manufacturers to offer third-party voice assistant support for Amazon’s Alexa and Google Home, and we were curious how they put it together. Sonos has benefitted from this surge in demand, offering a wide product lineup to create an immersive whole-home audio experience.
