The Xiaomi Mi portable speakers are well-deservedly popular due to their combination of sound, compactness and affordable price. However, even the most reliable technology can fail: Bluetooth fails, one speaker loses sound or the speaker stops turning on. Most of the faults lie inside the case, from oxidized contacts to damaged plumes. It is quite possible to disassemble the Xiaomi Mi column yourself, but the process requires accuracy and knowledge of key nuances.
In this article, you'll find a step-by-step photo manual, a list of tools you need, and common mistakes that beginners make when disassembling. We'll look at the design features of popular models, from Mi Portable Bluetooth Speaker to Mi Smart Speaker, and explain how to avoid damage to the board or speakers. If you've never done electronics repair, don't worry: you can cope with our tips even without special education.
Before you start, consider that disassembling the Xiaomi Mi speaker will void the manufacturer's warranty if it is still valid, and there is a risk of damaging fragile elements (such as a microphone module or battery) if you carelessly handle it. If you are not sure about yourself, contact the service center. But if you decide to act on your own, follow our recommendations.
What Xiaomi Mi models can be disassembled at home?
The design of Xiaomi speakers varies depending on the model and year of release.Some devices (for example, Mi). AI Speaker with voice assistants have more complex builds because of the extra microphones and sensors. Others, like Mi Portable Bluetooth Speaker, are relatively easy to understand. Here's a list of models that even a beginner can handle:
- π Xiaomi Mi Portable Bluetooth Speaker (Classic Round Column)
- π Xiaomi Mi Bluetooth Speaker 2 (with improved bass speaker)
- π Xiaomi Mi Smart Speaker (with voice control support)
- π Xiaomi Mi Pocket Speaker (Ultracompact Model)
- π Xiaomi Mi Outdoor Bluetooth Speaker (waterproof version)
It is more difficult to deal with the columns of the Mi series. AI Speaker or Mi Smart Speaker Pro β these are equipped with additional boards for processing voice commands, and their body is often sealed. If your model is not included in the list above, study its design on iFixit or in thematic forums before disassembling.
Note: Index columns IPX7 (For example, Mi Outdoor Bluetooth Speaker has enhanced water protection, and their body is sealed with silicone pads, which are easily damaged when disassembled. If you plan to assemble the device back, buy a remix of the pads in advance.
Required tools and materials
You don't need professional equipment to disassemble the Xiaomi Mi column, but you can't do without a minimum set of tools.
- π§ Plastic mediators (2-3 pieces) - for careful separation of the body. Metal screwdrivers can leave scratches!
- π§ Cross screwdriver (size) PH0 or PH00) β screw-hole.
- π§ Tweezers β to extract plumes and small details.
- π§ Dryer or thermo-air station - if the body is glued (relevant for models with a IP-certification).
- π§ Isopropyl alcohol (90%+) β Cleaning contacts and removing glue residues.
- π§ Multimeter β to check the integrity of the chains after disassembly.
- π§ Silicone gasket or sealant - if you plan to restore water protection.
If your battery is swelling, prepare:
- π§€ Protective gloves and glasses (electrolyte is dangerous!).
- π₯ Fire-resistant surface (e.g. ceramic tiles).
- π¦ A dense package for recycling an old battery.
β οΈ Warning: Do not use knives or other sharp objects to open the case! The risk of damaging plumes or speakers is extremely high. If the case does not respond to plastic mediators, warm it up with a hair dryer (temperature not higher than 60).Β°C) to soften the glue.
βοΈ Preparation for disassembly
Step-by-step: how to disassemble the Xiaomi Mi column
The disassembly process can be divided into 3 stages: opening the case, removing the board and speakers, diagnosing malfunctions. Let's consider each of them in detail with the example of Xiaomi Mi Portable Bluetooth Speaker (the most common model).
Step 1: Removal of the back cover
1. Turn the speaker downward (so as not to damage the membrane).
2. Insert a plastic mediator into the gap between the top and bottom of the case. Start with the control buttons, which are usually less glue.
3. Carefully swipe the mediator around the perimeter, gradually disengaging the latches. If the body does not respond, warm it slightly with a hairdryer (do not direct hot air to the speaker!).
4. After removing the lid, you will see:
- π Battery (usually glued to the body).
- π± Printed circuit board.
- π Dynamic (can be fixed with screws or glue).
What to do if the body does not separate?
Stage 2: Extracting the board and speakers
1 Unscrew the circuit board screws (usually 3-4 pieces). In some models, the board is mounted on the latches - carefully tuck it into the mediator.
2. Disconnect the plumes leading to the control buttons and the speaker. Don't pull the wires! Take the connector and pull it up gently.
3 If the speaker is glued, put a plastic blade around the edges. Be careful, the membrane breaks easily.
4 The battery is usually glued to double-sided tape. To remove it, grab the edge and slowly pull, heating the hair dryer (if the tape keeps up).
β οΈ Warning: If the battery is swelling, don't puncture it! It can cause fire. Place the column on a fireproof surface and carefully remove the battery without deforming it.
Stage 3: Diagnostics and troubleshooting
Now that all the components are removed, you can start looking for the problem, and here are the most common malfunctions and their signs:
| Symptoms. | Probable cause | How to check |
|---|---|---|
| Column not included | Failed battery or power controller | Call the multimeter power supply chain, check the voltage on the battery |
| No sound in one of the speakers. | The plume is severed or the speaker is damaged | Visual inspection of contacts, checking the resistance of the speaker |
| The column does not connect via Bluetooth. | Problems with Bluetooth module or antenna | Antenna cable vertebrating, checking soldered contacts |
| Distorted sound (wheezing, crackling) | Getting moisture on a board or speaker | Corrosion inspection, alcohol cleaning |
If you find oxidized contacts, clean them with a cotton swab dipped in isopropyl alcohol. To check the chains, use a multimeter in vertebrae mode. Do not solder wires without experience! - you should consult a specialist.
π‘
If the column stopped turning on after moisture hit, place the board in isopropyl alcohol for 10-15 minutes, then dry with a hair dryer (cold air) for 30 minutes.
Common Mistakes in Disassembly and How to Avoid Them
Even experienced craftsmen sometimes make mistakes that lead to the final breakdown of the device, and here are the most common ones and ways to prevent them:
- π The plume breaks, never pull the wires! Only take the connectors.
- π₯ Overheating of the board - when soldering, use a soldering iron with a capacity of no more than 30 W and a temperature of up to 300Β°C.
- π§ Moisture on the speaker - do not clean the membrane with wet wipes, use a dry brush.
- π Short circuit of the battery β do not put the battery on metal surfaces.
- π Damage to the speaker membrane - do not press the center of the speaker with your fingers.
Another common problem is the loss of screws or springs during disassembly, so to avoid this, use a magnetic mat or spread the parts in order of extraction (for example, left to right). If the screws vary in size, take a picture of their location before unscrewing.
Pay special attention to the silicone pads in waterproof models, if they break or deform, the column will lose its leakage, in which case you will have to buy a remix or use a sealant (for example, LOCTITE 595).
1. Correct connection of all plumes.
2. battery polarity (plus to plus, minus to minus!).
3. Integrity of control buttons (sometimes they "fail" during assembly).-->
How to collect the column back: tips and life hacks
Building a Xiaomi Mi column is often harder than disassembling, and here are some tips to avoid problems:
- Start with the speaker, put it in place and fasten it with screws (if any). Make sure the membrane doesn't touch the body.
- Connect the plumes, they must enter the connectors without effort. If the plume does not sit down, check if it is inverted.
- Secure the board - first screw all the screws "live", then tighten them cross-to-cross to avoid distortions.
- Install the battery -- if it sticks, use a new double-sided tape. Don't skimp on glue!
- Close the case, start with the button side, then click the rest. For models with glue, use a special adhesive (for example, for models with glue, B-7000).
After assembly, don't rush to turn on the column.
- π Correct connection of the battery (multimeter).
- π Integrity of speakers (light tapping β sound should be ringing, without wheezing).
- πΆ Bluetooth work (plug in to the phone).
If the speaker doesn't turn on, take it apart again and check the polarity of the battery -- that's the most common assembly error, and if the sound is distorted, it's possible that the speaker is not tightly mounted or that the membrane is damaged.

When the disassembly did not help: alternative solutions
If after dismantling and diagnostics, the Xiaomi Mi column never worked, do not despair.
- π§ Replacement of the fee β if the power controller or Bluetooth module is burned, it is sometimes cheaper to buy a new fee on AliExpress (price from 500 to 1500) β½).
- π Battery replacement β bloated or βdeadβ batteries can be replaced with similar ones (for example, a battery is suitable for the Mi Portable Speaker). 3.7V 1200mAh).
- π Use as an external amplifier β if only Bluetooth is broken but the speakers are working, plug in the speaker by AUX-cable (if there is a connector).
- π± Sale for parts β serviceable speakers or battery can be sold profitably on Avito or in thematic groups.
If the problem is in the software (for example, the speaker is turned on but not connected to the phone), try resetting.
- Hold the power button and Volume+ within 10 seconds.
- The column should emit an audible signal and reboot.
- After reset, re-pair with the phone.
If neither method helped, it may be cheaper to buy a new speaker.For example, the Xiaomi Mi Portable Bluetooth Speaker 2 costs about 2000. β½, and the repairs will cost 1500-2500 β½.
