We agreed, however, with glue variability being an issue that many Instrumental customers face, we also discussed how Instrumental’s machine learning algorithms help catch problems in the factory before they escape. Several people suggested that the glue was being used for sound or vibration dampening and electrical protection for an adverse drop event or long term reliability.

We discussed the copious amounts of hot-melt glue on the main power components and asked the audience what their thoughts were. Later, they determined it was worth the time and expense to implement these board changes and other improvements to lower the overall BOM cost for the rest of the product’s life.Īfter shifting back to the live teardown, I removed a further 6 screws to open up the back of the speaker chamber revealing the main guts of the device. The Sonos team likely made the decision to remove the microphones too late to make changes to the first production run having had to qualify the product for certification at DVT and placed orders to meet the PVT schedule.

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. Change Notice: Sonos One (Gen 2) Teardown Summaryĭuring the pandemic, a lot of people have been working from home and have invested in upgrading their home sound systems.
