How to disassemble the Xiaomi column: from Mi Portable to Redmi - instructions with photos and nuances

Xiaomi portable speakers are some of the most popular gadgets for music on the road, but even they are not immune to breakdowns. Whether it is a crack in the speakers, fast battery discharge or problems with Bluetooth connection, sooner or later the question arises: how to disassemble the device to fix it yourself? In this article, we will discuss in detail the process of disassembling Xiaomi speakers – from budget Redmi to flagship Mi Portable – point out the pitfalls and give tips how to avoid typical errors.

It is important to understand that the design of Xiaomi speakers differs depending on the model and year of release. For example, the 2018-2020 Mi Bluetooth Speaker was assembled on screws under a cross screwdriver, and newer versions (for example, Xiaomi Sound or Redmi Speaker Play) may have latches or even glue. We will look at universal methods, but before dismantling be sure to specify the model of your device – this will save time and nerves.

If you've never been a digital user, don't worry: Xiaomi speakers are medium-sized devices, and the key is to be careful, use the right tools, and take your time. FAQ Answering frequent questions, and tips on how to assemble the column back to make it work like a new one.

Preparation for disassembly: tools and security measures

Before you start a screwdriver, prepare everything you need, and without the right tools, you risk damaging the body, the speakers, or the board, and here's the minimum set you'll need:

• 🔧 Screwdriver kit: cross-haired (PH0, PH1), flat (1.5-2 mm), as well as triving (T5, T6) for some.
• 🧲 Magnetic mat or tray – so as not to lose small screws and details.
• 📸 Smartphone for photographing each stage of disassembly (useful when reassembling).
• 🔥 Hair dryer or construction thermoair – if the body is glued (relevant to Xiaomi Mi) AI Speaker or Redmi Speaker Player).
• 🧴 Plastic mediators or blades for disconnecting latches without scratches.

Also, do not forget about the safety measures:

• ⚡ Disconnect the column from charging and discharge it to 0% (this minimizes the risk of short circuit when working with the board).
• 🧤 Work with gloves or grounding to avoid static electricity.
• 🚫 Do not use metal objects to tamper with the case - only plastic or wood.

⚠️ Note: If your Xiaomi column is warranty-free, disassembly will void it. Check the warranty period in the Mi Home app or on the box before work begins.

Determine the type of mounting of the body: screws, latches or glue?

Xiaomi speakers design varies depending on the series. To avoid breaking the device, first determine how the body parts are bonded:

To check for screws, inspect the body for:

• 🔍 Rubber legs - screws are often hidden under them (carefully tuck the leg with a plastic spatula).
• 🏷️ Stickers or labels – sometimes they mask mounts (for example, on Xiaomi Mi Outdoor Bluetooth Speaker).
• 🕳️ Microphone or speaker holes – screws can be next to them.

If you can't see the screws, you're probably holding the body on latches or glue, and you're going to need to have a gentle hair dryer warm-up (not above 80).°C to avoid damaging plastic and using plastic mediators to separate parts.

💡

Before heating, wrap the column case in a food film - this will protect it from overheating and help evenly distribute heat.

Step-by-step dismantling of the Xiaomi column: from the case to the board

Consider a universal disassembly algorithm using the Mi Portable Bluetooth Speaker (similar to most models), and if your column is different, adapt the steps to its design.

Step 1: Removing the back cover

1. Place the speaker down on a soft surface (for example, a towel).

2 If you have screws, unscrew them and put them in a magnetic tray. If there are no screws, heat the edge of the body with a hairdryer around the perimeter (30-60 seconds).

3. Put a plastic mediator in the gap between the front and rear panels and guide them gently around, disengaging the latches. Start at the corner where the charging connector is, which is usually less glue.

Step 2: Battery disconnection

After removing the cover, you will see:

• 🔋 Battery (usually glued or fixed with double-sided tape).
• 🔊 Speakers (can be soldered or connected via connectors).
• 📱 Control board (with chips and Bluetooth module).

First, disconnect the battery to avoid short circuits.

1. Take a picture of the location of the wires.
2. Carefully unfurl or disconnect the power connector (usually red and black wires).
3. If the battery is glued, put it with a plastic spatula.

⚠️ Warning: Do not use metal tools to work with the battery, this can cause it to swell or ignite. If you notice that the battery is swelling, do not try to repair it - dispose of it according to the rules of your region.

Step 3: Dismantling speakers and boards

The speakers in Xiaomi speakers are usually mounted on screws or latches. Unscrew them and put them aside. The control board can be removed after all the connectors (Bluetooth antenna, control buttons, microphone) are disconnected.

If you want to replace a speaker, pay attention to its impedance (resistance) and power – they must match the original. For example, in the Mi Portable Speaker, 4 ohm speakers are used, and in Xiaomi Sound – 8 ohms.

Typical breakdowns and how to fix them

Once you've taken a column apart, you might encounter a few common problems, and here's how to diagnose and fix them:

1. The column is not switched on or charged

Possible causes:

• 🔌 Damaged charging connector - check it for oxidation or breaks.
• 🔋 Failed battery - bloating or lack of voltage (checked by multimeter).
• 📱 Burned control board - usually accompanied by the smell of burning or blackened elements.

Decision:

• If the problem is in the connector - clean the contacts with alcohol or replace the connector ( soldering requires experience).
• If the battery is faulty, replace it with a similar one in capacity (for example, a battery of 1200-1500 mAh will suit the Mi Portable Speaker).
• If the fee is burned, repairs may not be cost-effective - it is cheaper to buy a new column.

2. Crackling or lack of sound

Reasons:

• 🔊 Damaged speaker - rupture of the membrane or a wire break.
• 📶 Bluetooth module problems – the speaker connects, but the sound is interrupted.
• 🔈 Pollution dynamics – dust or moisture inside.

Decision:

• Check the integrity of the speaker membrane - if it is torn, replace the speaker.
• Test the speaker through aux input (if any) – if the sound is coming, the problem is in the Bluetooth module.
• Blow the speaker with compressed air or gently clean with a cotton swab soaked in alcohol.

3. The column does not connect via Bluetooth

This is one of the most common problems.

• 📡 Firmware failure – column is enabled but not visible in the list of devices.
• 🔄 Damaged Bluetooth module — physical breakdown on the board.
• 🔋 Low battery power – some models turn off Bluetooth when under 10%.

Decision:

• Reset the column settings (usually by pressing the power button for 10-15 seconds).
• Check the integrity of the Bluetooth antenna on the board – it can be soldered or connected via a connector.
• Update the firmware through the official Mi Home app (relevant for smart Mi speakers) AI Speaker).

How to collect the column back: tips and life hacks

Building a column after repair is as important as disassembling, and here are the key points to consider:

1. Check all the connectors -- they need to be tightly connected, without any distortions, especially in the battery and speakers.
2. Make sure the seals are intact – if the column has moisture protection (e.g. Xiaomi Mi Outdoor Speaker), check the rubber pads.
3. Twisting the screws cross-cross to avoid skewing the body.
4. Test the speaker before final assembly - plug it into charging and check the sound, Bluetooth and buttons.

If the column case was held on glue, use bilateral tape 3M Or a special glue for plastic (like Loctite 406). Don't overdo it with glue - the excess can get inside and damage the board.

💡

After assembly, allow the glue or tape to dry for 1-2 hours before the first inclusion of the column.

If the column does not work after assembly:

• 🔍 Check if you have forgotten to connect any connector.
• 🔋 Make sure the battery is charged (plug the speaker into the network for 30 minutes).
• 📱 Reset the settings to factory (press the power button for 10-15 seconds).
