How to disassemble the Xiaomi Mi Bluetooth Speaker Basic 2: detailed guide with photos and tips

Xiaomi Mi Bluetooth Speaker Basic 2 is a compact and popular device with high-quality sound, but even it is not immune to breakdowns. Over time, speakers can fail, battery drain or control buttons break. In most cases, repairing is cheaper than buying a new speaker, but you need to be able to properly disassemble it.

This article will help you avoid the typical disassembly errors that often damage the body or internal components, and we will take a detailed look at the tools, sequences, and tips for diagnosing faults. If you've never been to electronics, don't worry, the manual is adapted for beginners.

Important: disassembling the column will void the Xiaomi warranty if it is still valid. Before starting work, make sure that the warranty period has expired or you are ready to lose the opportunity for free repairs.

Preparation for disassembly: tools and security measures

Before you start disassembling the Mi Bluetooth Speaker Basic 2, prepare the workplace and the necessary tools, which will save time and protect the device from accidental damage.

You'll need:

• 🔧 Plastic blade (or mediator) - for careful smearing of the body without scratches.
• ⚒️ Cross screwdriver (size) PH0 or PH00) — screw-off.
• 🔋 Tweezers – help to extract small parts, such as plumes or connectors.
• 📸 Smartphone or camera – to photograph the disassembly process (useful when reassembling).
• 🧲 Magnetic mat or container – for storing screws and small parts.

Also, do not forget about the safety measures:

• ⚡ Disconnect the column from charging and turn it off 3-5 seconds before the start of disassembly - this will prevent short circuit.
• 🧤 Work with gloves (optional) to avoid static electricity.
• 🌡️ The temperature in the room should be 18-25°C – at low temperature, plastic becomes brittle.

⚠️ Warning: Do not use metal tools to smear the body, they leave scratches and can damage the latches. If you do not have a plastic blade at hand, wrap the screwdriver with a screwdriver.

Before disassembling, it's helpful to understand how the column works from the inside, so you can avoid damaging critical elements and find faults faster.

Mi Bluetooth Speaker Basic 2: Main Components

The most vulnerable elements are plumes (connecting the board to buttons and a speaker) and a battery (can swell over time). If the speaker does not turn on, in 60% of cases the problem lies in the battery or contact board.

Interesting fact: the Basic 2 uses the same speaker as the more expensive Mi Bluetooth Speaker, but without waterproofing, which means that with careful disassembly, you can replace the speaker with a counterpart from another Xiaomi model.

💡

If the speaker is wheezing at high frequencies, it's probably a problem with the dynamics. Before disassembling, check the sound on another device, perhaps it's the source of the sound, not the speaker.

Step-by-step: how to disassemble the case Xiaomi Mi Bluetooth Speaker Basic 2

Now, to the disassembly process itself, follow the instructions carefully so that the latches of the body are not broken.

Step 1 Remove the back cover

The column case is held together with 4 screws under a cross screwdriver and 6 plastic latches.

1. Turn the column up with the back panel.
2. Unscrew the screws in the corners (they can be hidden under stickers - gently put them under a knife).
3. Insert a plastic shoulder blade into the gap between the front and back panels (start at the corner next to the power button).
4. Carefully drive the shoulder blade around the perimeter, snapping the mounts.

Step 2. Disconnect the plumes

After removing the cover, you will see:

• 🔊 Dynamics (adhesive to the front panel).
• 🔋 Battery (soldered to board).
• 📶 Board with Bluetooth module and buttons.

Before you continue, disconnect the plumes:

1. Take a picture of the plume's location.
2. Carefully tuck the connectors with tweezers (do not pull the wires!).
3. If the plume does not detach, check if there is a latch.

⚠️ Warning: Do not force when disconnecting the plumes, they are fragile. If the connector does not respond, check if it is blocked by a plastic lock (often on the battery connectors).

Diagnostics of malfunctions: what to check first

After disassembly, you need to determine which component is out of order, and here are the most common problems and ways to diagnose them:

1. Column not included

• 🔋 Check the battery: if it is swelling, it needs to be replaced. Measure the voltage with a multimeter (should be 3.7-4.2 V).
• 📱 Check the charge for burnt elements (blackened resistors, swollen capacitors).
• 🔌 Check the charging connector contacts (often oxidized or departed).

2. No sound or distortion

• 🔊 Call the speaker with a multimeter (resistance should be 3-5 ohms).
• 🎛️ Check the soldered speakers contacts on the board - they can move away from vibration.
• 📻 If the sound is intermittent, the problem may be in the Bluetooth module (flash the column over).

3. Bluetooth is not working.

• 📡 Try resetting (press the power button for 10 seconds).
• 🔄 Check the Bluetooth antenna (thin wire on the board) - it could have moved away.
• 🖥️ Update the firmware through the official Mi Home software (if the column at least somehow reacts to the buttons).

If you're not sure about your soldering skills, you'd better trust the board repairs to professionals, for example, replacing a burned resistor is cheaper than buying a new column, but requires experience.

Battery replacement: analogue selection and installation process

The battery is one of the most common causes of failure of the Mi Bluetooth Speaker Basic 2. Over time, it loses capacity or swells, which leads to failure of the speaker, you can replace it yourself if you follow the instructions.

Which battery to choose?

The original battery has parameters:

• 🔋 Capacity: 1200 mAh.
• 🔌 Voltage: 3.7 V.
• 📏 Sizes: 45×30×5 mm (exact dimensions can be specified after the old battery is removed).
• 🔌 Type of connector: JST 2-pin (step 2.0 mm).

Suitable analogues:

• 🛒 Xiaomi Original Battery (Article) MB-BAT-1200) — original, but expensive.
• 🛒 Baseus or Remax batteries with similar parameters.
• 🛒 Lithium-polymer batteries from 18650 (soldier iron required to connect).

Replacement process:

1. Set the old battery off the board (or disconnect the connector if it is removable).
2. Install a new battery while observing polarity (+ and –).
3. Seal the contacts or connect the connector.
4. Secure the battery with double-sided tape (so that it does not hang inside the case).

⚠️ Note: If you are using a battery from 18650, make sure it has a built-in protection charge (PCB). Without it, the risk of overheating or bloating is much higher!

💡

When soldering the battery, don't overheat the contacts, which can damage the battery. Use a soldering iron with a power of no more than 30 watts and work quickly.

Column Builder: How to Avoid Mistakes

After repairing or replacing components, you need to properly assemble the column to make it work as before.

1.Pre-assembly check

• 🔌 Connect the column to the charger and make sure it turns on.
• 🔊 Check the sound at different frequencies (use test tracks).
• 📶 Make sure Bluetooth connects without failure.

2. Laying of plumes

The plumes should be flat, without any inflections, and if they are clamped together, it can cause the contacts to break.

• 📏 The plume of the dynamics is not stretched.
• 🔌 The snails are clearly visible (the snails should be heard).
• 🧲 No foreign metal objects inside the body.

3. Rotary screw twisting

The screws should be twisted in the following order:

1. First, fix all the latches of the case (make sure that they are snapped).
2. Wrap the screws diagonally (first two in the corners, then the remaining ones).
3. Do not pull the screws - this can damage the thread in the plastic.

If the column malfunctions after assembly (for example, spontaneously turns off), disassemble it again and check:

• 🔋 Battery contacts (possibly poor soldering).
• 📱 Short circuit charge (check multimeter).
• 🔊 Dynamics - it could shift during assembly.

Frequent Mistakes and How to Avoid Them

Even experienced wizards sometimes make mistakes when disassembling Xiaomi Mi Bluetooth Speaker Basic 2. Here are the most common of them and ways to prevent them:

Damage to the latches of the shell

If you push too hard with your shoulder blade, the plastic latches can break.

• 🔧 Use a thin plastic blade (no more than 0.5 mm thick).
• 🔥 Heat the body with a hair dryer (temperature 40–50)°C) - plastic will become softer.
• ⏱️ Take your time, and then take the slack off.

2.Slide plumes break

The plumes in the column are very thin and easily torn, so as not to damage them:

• 🖲️ Never pull the wires, just the connector.
• 🔍 Before disconnecting, check if there is a fixture (sometimes it needs to be lifted).
• 📸 Take a picture of the location of the plumes before disconnecting them.

3. Overheating at soldering

If you solder a battery or speaker, high temperatures can damage the board.Tips:

• 🔥 Use a soldering iron with a capacity of 20-30 watts.
• ⏳ Drink no more than 3-5 seconds for one contact.
• 🧊 Allow the board to cool before switching on (minimum 2-3 minutes).

4. Wrong assembly

If the column doesn’t work after assembly, it’s likely something is missing:

• 🔍 Check if all screws are twisted (sometimes one is forgotten to insert).
• 🔌 Make sure the plumes are connected to the correct connectors.
• 📋 Check the photos taken before the demolition.

💡

If you've got a speaker that's squeaking or wheezing after you've repaired it, it's probably the wrong polarity. + and-and check the sound again.
