Want to contribute? Google Home smart speakers play music, answer questions, and control various smart gadgets installed in a home. One can see the gold-plated tip of the stainless-steel is to connect with the golden contacts visible on the PCB. Below you can see the capacitive touch sensor consisted of stamped sheet metal adhered onto the inside of the plastic shell, surrounding the LED light pipes. The dimensions and weight of the unit, per Google’s product page specs, are: depth: 2.65 in (67.3 mm) width: 7.02 in (178.5 mm) height: 4.65 in (118 mm) weight: 16.9 oz (480 g) And as usual, I’ve included a 0.75″ (19.1 mm) diameter U.S. penny for size comparison. Ah, the pretty, soft-touch, and expressively-colored base-plate. On initially hearing that the controls required tapping, I thought this might have been done by an accelerometer, which we can see it wasn’t. The fabric shell has corresponding insulating and padded Kapton tape, to ensure a snug fit, and probably to prevent direct moisture or contaminants from glitching out the capacitive sensing. Now lets take a look at the capacitive-touch volume controls, which did seem to be behaving. After turning the device over, you can gently lift the fabric-covered top. To date, Google Home, the subject of this teardown, is only available in the US (although some UK users have imported them but with varying experiences as to how much functionality crosses the Atlantic – so be warned). This teardown is not a repair guide. These are used for sensing side-taps for volume control. The speaker is incredible for its size, easily outperforming the Echo Dot, but it won’t fill a room in quite the same way as the regular Home. 2. share. And lastly, what could have gone wrong with the tap control to cause the. Let's look at your Home's specifications: ... Marvell 88DE3006 Armada 1500 Mini Plus dual-core ARM Cortex-A7 media processor. Removing the adhesive and the torx screws now allows the two halves of the product to easily come apart, revealing a ribbon cable that needs to be unplugged before completely seperating. These translators are helping us fix the world! 8GB vs 16GB M1 MacBook — Does It Even Matter? at Snatcher. No long term harm here, as the shield covers will still protect from any noise once replaced. How is a single speaker used to create uniform omnidirectional sound, from behind the LED dots and touch controls all while embedded under the fabric? It is a variant of Google Home with the same overall functionality, but in a smaller pebble-like form factor around 4 inches (10 cm) in diameter, with a fabric top that its white-colored status lights shine through. If there is still glue over the screw heads you can easily pierce with the screwdriver. Thanks. Accessibility. Removing the black enclosure, we can see it is indeed an impressively sized custom speaker enclosure, and we get a hint at the solution to providing omnidirectional sound from the metal shape below. Want the latest weather, traffic, finance, sports and more? And as with most MEMS microphones used today, the port is on the bottom, requiring a hole through the PCB, as can be seen below. The flex cable connects to a small interfacing PCB, with a USB header, a toggle switch (for disabling the microphone), and a reset button on the reverse, intended to be pressable through the baseplate. While the Google Home Mini and Amazon Echo Dot were given birth by two feuding giants, and they look very different on the outside, what’s on the inside does not appear too different. We can see some familiar chips from the previous and originial Google Home. Lets have a closer look at this metal/plastic part, and see how it contributes to the design. Step 1 Google Home Mini Teardown. figuring out the location of the sound, similiar to how two ears on opposite sides of one’s head does. Do not remove glue, as the bottom will not hold otherwise later. I’m open to learn about how this compares in terms of time and cost on the assembly line. But the metal could also add strength and tight tolerances to what is the main structural component holding everything else together, while also adding a bit of weight, helping the little Google Home Mini feel more solid and sit better on a table-top. April 24, 2018 by Brian Dipert Comments 0. All Google had to do was make the Home more conversational than its streaming dongle.

The feature-turned-bug was a touch sensor that could be used trigger the device to start listening without having to say the magic “Ok Google” wake command. Interesting note: A “pick-and-place” assembly machine uses a vacuum to pick up the tiny electronic components from a reel and then place them onto the PCB. With most of the PCB components covered, we can move our attention to the source of an unfortunate bug, that caused some early devices to continuously listen to audio. Now move around with the spudger under the plastic plate until the adhesive has dissolved on the entire surfacem. One could use a specialized custom heat-pack for this. Now loosen 4 more screws on the top of the unit. Simply ask. It seemed obvious there were some screws hiding beneath this, but seeming really difficult to pry off, I attempted to find some snaps holding together the fabric shell and plastic base, that I could pry apart instead. Google's latest smart speaker emphasizes smart over speaker: it's a small pebble of a thing, about the size of a crosswise slice of a softball. The first teardown of the Samsung Galaxy S21 series has now been shared online with some admittedly minor internal differences from last year’s Galaxy S20 model. View Offer. Google Home 1.26 adds Home Max support & bass, treble settings, details speaker pairing, tablet UI, ‘Room EQ’ [APK Teardown] Abner Li - Nov. 14th 2017 2:13 pm PT Fun hack: If the Mini had Bluetooth speaker support, one would have been able to use the Echo Dot as a $49 ‘Bluetooth-to-audio jack adapter’, while also having the redundancy of two voice assistants through the same speakers. there is low variation in how sensitive manufactured components are to different frequencies ) which makes them great for these beam-forming and noise-cancellation algorithms. The Google Home Mini opens from the bottom There is an orange plastic disc with a piece of orange rubber attached to it. The plastic overmolding however indicates the 13th August.

Regionaut - The packaging is obviously intended for retail, given the hang tab, is well designed and cost effective, with a neat perforated tear-tab, and white pulp trays cradling the product. (I would not put it past Google) It also looks like the white plastic base was manufactured a month later, in September, likely due to the stricter cosmetic requirement meaning it was iterated on during validation runs more than internal parts. Is there something I am missing, or did tight production schedules require time travel? Removing the hopefully final set of 4 torx screws, we set free the interesting metal/plastic part, and finally reveal the main PCB. The Nest Mini is about the same hockey-puck size as its predecessor, but it's a real step up in sound. A relatively minor cost reduction. But I quickly ran into my biggest gripe: for what would mostly be used as a music playing assistant, there is no way to directly connect external “dumb” or even Bluetooth speakers, or support of audio over USB-C, as in the Pixel 2. Google Home relies on its Google Assistant, similar to the way Amazon Echo relies on Alexa and Apple devices use Siri. MEMS microphones are ideal for this, as they have tight sensitivity matching (i.e. The other trade-off’s with having a bottom-port relate to cost and frequency response. NÃME Technologys and Designs - Sitting next to the Google Home and Home Mini, the Max is massive. Texas Instruments TAS5720 audio amplifier. Instead the solution to connect to external speakers here is to buy a $35 Chromecast audio to connect to them over Wifi. If cheap enough, this may have actually helped provide the redundancy necessary to eliminate false positives on the capacitive touch sensors, but hindsight is 20/20. Looking at the single main PCB of the Mini, and that of the Dot, one can see how simple it has become to make a voice assistant, and can assume this will start to become commodified, leaving the innovation to either the AI and Natural Language Processing itself, or the integration of this hardware into other products rather than being just a standalone device. The rest of the stainless-steel part is sprung against the metal frame with foam adhesive, ensuring a tight press against the fabric shell, while still preventing electrical contact with the metal part.

I was drawn to Google’s new design direction, that’s come a far way from their serif, primary-colored type-logo, notably the expressive colors, creative use of materials, the nod to Olivetti and Italian design, and lastly I couldn’t help but be wooed by the playful association to a donut, towards which I have a soft spot. And so I believe we need more people understanding and building this type of technology, to make the chances higher that the future we build will be one that we all want. Our expert audio engineers developed proprietary audio tuning software, allowing us to get the most out of the hardware with a full, clear and natural sound at every volume level. No doubt a lot of acoustic engineering went into this…. The dust problem reported has to do with the original GH, not the Mini. I hope you enjoyed this teardown and took something away from it — if you did, please clap away at the button below. While the new Echo line has a fabric exterior, it does feel more like an afterthought than part of the original design intent. Peeling back some adhesive foam, you can see a flex cable soldered directly to the board — marginally cheaper but significantly tougher than the ZIF connector used on the other end of the cable. When Google released the Home Mini, the lack of a line-out jack was a familiar complaint.It meant users wouldn’t be able attach the device to more powerful speakers and enjoy improved audio. Or related to the heat-generating Dual-Core ARM Cortex A7 directly beneath the contact. Bennet Heidekorn - © 2021 iFixit — Licensed under Creative Commons — Privacy — This could be an attempted fix of a potential bad connection of the sheet metal to the PCB in the case of some tolerance misalignment or spring fatigue.
