If you put too much force on the screwdriver, you’ll pop a corner free and bend the whole thing up - don’t do that. Work around the edges until the grille comes free. Be careful - you don’t want to bend it up more than needed. Push the screwdriver in, pry gently at the corners and you should get the grille to come up. The least-destructive way I found was a flathead screwdriver, coming from the charge/power port opening. You have to remove the rear grille to get access to the screws, so may as well start there. There’s no obvious way into the speaker - because there’s seriously no obvious way in. I hate the lead free stuff, so I’m excited, if a tiny bit confused about how they got that through in 2013. Based on having to resolder a wire I popped loose from a speaker while messing around, I believe it - the solder didn’t behave like lead-free solder. It’s got a UL listing, and, interestingly, I see no ROHS markings. Looking at the (somewhat worn) specs on the bottom, we see this is a part 886-000015, model S-00136, FCC ID JNZS00136. This is a “toss it in your bag and take it with you” speaker. It’s not audiophile grade audio, but then this isn’t an audiophile grade speaker either. The driver size doesn’t really matter, though - the audio chip only seems to support SBC over Bluetooth (it’s an old, somewhat crappy audio codec), so unless you’re using the aux in port, it’s not like an amazing signal gets into the device in the first place. If you want to pair multiple of them together, you can (this feature mostly existing to drive buying more than one, instead of just buying a bigger speaker, as far as I can tell). They put out enough sound to fill a small room, and are useful enough outside, though it’s not by any means a massive speaker - the twin drivers just don’t move that much air. The Mini Boom showed up in 2013 or so, and has been a fairly popular bluetooth speaker since then - the bass is decent (helped by the case design), the battery life is decent enough, and it’s just an acceptable little knock around speaker. Don’t build things like this.Īnyway, what’s inside? How do you get inside, anyway? Keep reading to find out! The UE Mini Boom On the plus side, they did design it to last - but, seriously. It’s got glue, it’s got soldered connections where headers would make sense, and it’s just a pain to work on. It’s not even waterproof, which is a common excuse for hard-to-take-apart things. It’s hard to get apart, you can’t get it back together without heroics, it doesn’t look the same after you get it back together, and… I just don’t understand why you’d do this. This little gizmo is a perfect example of “nearly unmaintainable consumer crap,” and I’m going to rip on it as I go - there is no reason to build something this hard to work on, and I think it’s irresponsible for consumer product companies to build stuff this way. The Mini Boom is an older Bluetooth speaker that was quite popular some while back - and they’re not particularly well documented. I’ve not found a great teardown of a UE Mini Boom - and, especially, nothing talking about battery replacement.
