Einleitung
The Boomphones Pocket Speaker is an interesting Bluetooth-enabled, portable speaker. It can easily fill a room with music while maintaining a small, pocketable form factor. What kind of sorcery does this little speaker is packing inside? Let's crank up the teardown, shall we?

-
The side of this super compact Bluetooth speaker is covered with a rubbery silicone cover.
-
From the outside, it looks like there are no screws to open this little monster. Maybe it's hidden under the silicone band surrounding the sides.
-
The silicone band is secured with double-sided-tape-like adhesive to the plastic case.
-
We can remove this rubbery silicone cover by wedging a flathead screwdriver in between the plastic case and the silicone cover. Just be careful not to scratch the plastic case in the process.
-
After some plying of the silicone band off case, continue peeling it carefully on all sides until it comes off completely from the plastic case.

-
Finally, some screws! Let's crack open this baby with a Philips head screwdriver. There are a total of 7 screw holding the case together.
-
-
-
After all 7 screws are removed, we can easily crack this thing open. And voila! We can clearly see 4 speakers and the mainboard. The sides of the case has some kind of foam to make sure air moving inside the case can't easily escape to provide maximum vibration to the passive radiator.

4 tiny speakers

One of the two passive radiator

-
Each speaker is rated at 8 ohms and 1.2 watts. Combined, it makes 4.8 watts of audio power. This baby boombox packs some serious punch.
-
After removing 2 Philips head screws, the speaker can be pulled from the case.
-
-
-
Removing 4 Philips head screws on every corner of the mainboard enables us to lift it off and see what's hidden behind it.
-
CSR 57E6 Low power consumption Bluetooth chip
-
MX29LV160DBXBI-70G 16M flash memory chip
-
Nsiway NS 4158 2.6W Mono Amplifier (one for each stereo channel)
-

-
Unidentified IC, presumably for power management and battery charging

-
This pocket speaker is relatively easy to teardown, I give it 9/10.
-
The battery can be easily replaced by twisting the retaining clip on the mainboard
-
Standard Philips head screws make opening easy
-
Minimal adhesive (not too strong) on the outer silicone cover
-
No detailed documentation on the electronics and official teardown guide

So useful! I'm gonna buy it soon~
is it possible to add an output 3.5mm jack ?
With some Dremel works & soldering, it is absolutely possible :D
Connect the 3.5mm jack to the speaker connector (on step 3, marked with orange color). Please do it carefully, I'd love to see your result if it works!
Can I replace the battery with the bigger ones?

Possible, but maybe you can only replace it with just a little bit bigger size (maybe from 1000mAh to 1200mAh) because the original battery itself already takes a good amount of available space inside. You can always use portable power banks to power this thing.
