    • Phillips #0 and #2 Screwdriver

    • Flathead 3/32" (2.5mm) Screwdriver

  2. The AXX 200 is well put together. And by that, I mean the plastic housing on the back is held in place by adhesive. Lots and lots of adhesive.
    • The AXX 200 is well put together. And by that, I mean the plastic housing on the back is held in place by adhesive. Lots and lots of adhesive.

    • Start by using opening picks to remove the adhesive holding the back casing. A hair dryer or heat gun would help.

    • Plastic opening tools are also brought into the picture to get past the sticky adhesive and to pry open the back casing.

    • A spudger with a longer tip would be more helpful – or a plastic ruler could work as well.

    • After getting through the adhesive, lift the back casing open as pictured.

      • Warning: CAREFUL! A flex connector holds the buttons on the back casing to the unit, so don’t be too eager pulling the back casing away.

    • Disconnect the flex connector by simply pulling it downwards with a pair of flat-head tweezers

    • Then, remove the button PCB panel with a Phillips #0 screwdriver.

    • Remove the audio chamber by unscrewing the 6 screws with a Phillips #2 screwdriver.

      • Warning: lift up the delicate NFC sensor with tweezers before opening the chamber. You will have to peel off any excess adhesive to reveal the screw holes.

    • It’s a sizeable audio chamber for such a small speaker. Upon opening it up, you will easily identify:

    • 5200 mAH lithium ion battery

    • Port tube for boosted bass

    • Drivers x 2

    • You’ll also notice that all the cables (and there are a lot of them) are shielded with foam to prevent rattling.

    • Great Odin’s raven! That’s a big battery!

    • It’s a whopping 3.7V Li-ion battery with 5200mAh, and it’s used to power the device and charge your phone.

    • The built-in port tube enhances bass.

    What has not been mentioned it this is stock battery, but there is a another PCB hidden in the end of battery which houses the charging logic. This converts from a two wire (common and live rail, black and red) to a three wire (black, red and yellow) to monitor the charging status.

    • There is a hidden PCB in end of the battery, check here for charging issues

    • Using tweezers and screwdrivers, carefully remove the black tack (or adhesive putty) used to keep the cables in place at both ends of the chamber.

      • Sound Blaster really hasn’t stinged on the putty. There is a lot of it. It makes for an airtight enclosure, but the amount of putty really is quite overwhelming. Have I mentioned there’s a lot of putty? Oh okay, good.

    • Two microphones can be spotted at the top of the audio chamber, but there’s no way to access them from here.

    • Once the cables are loosened, remove the drivers with a Phillips screwdriver.

      • The unique positioning of the drivers allows for a wider sound spectrum. Both drivers measure about 1.6 inches (or 40 mm) each.

    • The next step is to open the bottom chamber.

    • Peel open the rubber base to reveal more screw holes.

    • Unscrew the base cap with a Phillips screwdriver.

      • Be careful not to expose the metal contact on the base to moisture.

    • Use a flathead 3/32" screwdriver to carefully unhook and release the catch holding the PCB.

      • Be gentle so you don’t break the plastic catch.

    • The various ports at the bottom of the AXX 200 seem to be separated into different PCBs.

    コメントを追加する

    • There are a total of four PCBs neatly stacked up to fit in the small AXX 200 chamber. It minimizes space. Saved space = bigger audio chamber = better audio.

    • To take out the stack of PCBs, first, disconnect the flex connector with tweezers.

    • After that, disconnect the two connectors. These are probably connected to the microphones at the top.

    • Lastly, disconnect the final connector that is linked to the battery from the bottom PCB.

    • The first PCB houses the microSD card slot, which allows for MP3 playback and voice recording.

    • First, remove the top two Phillips screws to detach the microSD card slot PCB.

    • Gently disconnect the microSD card slot PCB from the stack.

      • MicroSD card slot

    • The next PCB in the stack houses the USB port for smart device charging.

    • Proceed to remove the screws on the PCB with the USB 2.0 port.

      • USB 2.0 port

    • This PCB also has a Bluetooth chip processor integrated onto it.

    • Here’s the tough part. Separating the audio board requires some soldering. It also doesn’t help that I have the ugliest soldering iron on the face of the planet.

    • Use a (prettier) soldering iron to melt the solders and remove the four cables connected to the audio board.

      • 3.5 mm Aux-in / Mic-in jack

      • 3.5 mm headphones jack

    • Remove the two screws to detach the audio board from the bottom PCB.

      • Warning: There is another cable soldered to the bottom of the audio board. Handle the audio board carefully.

    • Flip the audio board carefully and you will see another cable attached to it below. Using the soldering iron, melt the solder on the audio board to detach the cable.

    • That’s the sb-axx1 quad-core sound processor, which Sound Blaster says makes the device intelligent.

    • With the bottom fully dismantled, move on to the top – the glass panel.

    • A word of caution: unless God has blessed you richly with magical fingers, or you have A LOT of flux solvent and patience, chances are you’ll end up cracking this thing.

    • Firmly attach a small baller suction cup on the touch panel.

    • Then, carefully pry open the touch panel with a hobby knife.

      • Warning: The plastic touch panel is very tightly sealed and prone to crack. Handle the touch panel with care.  Drip flux solvent in between the gaps to dissolve the adhesive.

    • Unscrew the six screws located at each corner of the top panel.

    • Then, remove the four screws in the center to open the top panel.

      • There are cables attached to the top panel. Open the top panel with care.

    • Unplug the NFC cable connected to the top panel.

    • Disconnect the flex connector to completely remove the top panel.

    • Remove the rubber strips on the side with a flat-head screwdriver.

    • Lift up the plastic casing with a flat-head screwdriver.

      • The plastic casing ensures the LED lights are shielded to prevent bleeding of light.

    • The LED lights on the touch panel are covered with rubber light guides.

      • Light guides allow the individual LEDs to light up one by one on the touch panel. Neat.

    コメントを追加する

    • Below the touch panel are FOUR microphones. Not one, not two… FOUR.

    • Remove the adhesive (sigh) around the microphones with a flat-head screwdriver

      • Solvent may be used if the adhesive is too tough to remove.

    • Next, remove the flex connector through the slot.

      • This is the main flex connector that runs from the bottom to the top panel.

    • This is another light guide for the LED that acts as the AXX 200’s Bluetooth indicator.

      • The actual LED is located on the touch panel PCB.

    • The white metal grille at the front is also removable. If you find white a little understated, this would be the part where you break out the spray paint from the garage and go to town on this bad boy. A little unfortunate that you have to remove everything else before being able to remove the grille.

    • To remove the metal grille, pry open the two catches using a flathead screwdriver.

    • Lastly, slide the inner chamber out from the metal grille casing.

    • Voila! The Sound BlasterAxx AXX 200 in pieces.

    • Tearing apart the AXX 200 requires patience.

    • The glass touch panel breaks easily. It is highly unlikely that you can restore the AXX 200 to its original condition without some scratches or cracks.

    • There are a large number of tiny screws holding together the AXX 200. It would be best to keep the screws in the order you removed them.
