The decision to disassemble Xiaomi’s soundbar often comes when the device stops turning on, the sound becomes hoarse or battery replacement is required in portable models. Unlike smartphones, the brand’s acoustic systems do not have official service manuals in the public domain, which forces owners to act through trial and error. The wrong approach to opening the case can damage plastic latches or rupture the thin plumes of the speaker.
Before you start a screwdriver, you need to know exactly what model you're dealing with. Mi TV Soundbar, Mi Compact Speaker and Gaming Soundbar games have fundamentally different build patterns. Some are assembled on screws hidden under rubber legs, others are exclusively glue-based and tight latches. It's critical to determine the type of attachment before work begins, because applying force to the glued body without warming up will lead to irreversible cracks.
In this article, we will take a closer look at the dismantling process, the tools and precautions you need to take: how to safely disconnect the Bluetooth module, check the condition of the capacitors and clean the insides of dust. Competent disassembly is the first step to successful repairs that will extend the life of your audio system without going to a service center.
Tools and workplace preparation required
The cross screwdriver is not enough to disassemble electronics properly. Xiaomi soundbars are often assembled using different caliber screws and specific fasteners. You will need a set of precision screwdrivers that include the sizes of the PH0 and PH1, as well as a flat stinger for working with latches. Using the wrong tool can lick the screw hats, which will greatly complicate further repair.
Special attention should be paid to tools for opening the case without damage. Plastic mediators or special spudger blades are mandatory, since a metal knife will leave deep scratches on the glossy plastic. For models assembled on glue, a hairdryer or a professional hot water heater Hot Air Station is necessary to soften the adhesive.
Prepare the workspace in advance. The surface should be clean, well-lit and not conduct static electricity. It is recommended to use an antistatic mat or at least natural fabric. Also prepare containers for sorting screws, as their number can vary from 4 to 12 pieces depending on the model.
- 🛠️ A set of precision screwdrivers (cross and flat).
- 📱 Plastic blades and mediators for opening.
- 🌡️ Hair dryer or heat heat heater for working with glue.
- 🧲 Magnetic mat or organizer for screws.
⚠️ Warning: Before any work begins, be sure to disconnect the soundbar from the power grid and let it cool completely if it was working.Residual voltage in the power supply capacitors can be dangerous.
Determination of the type of anchorage and access points
The first step is always a visual inspection of the case. Electronics manufacturers, including Xiaomi, are committed to minimalism, so visible screws are often absent. Carefully examine the back panel and the bottom of the device. Often the mounting points are hidden under decorative plugs, rubber legs or stickers with technical information.
If there are no screws at all, then the body is assembled on the latches, in which case the seam between the front and back of the body runs along the entire perimeter, sometimes access to the insides is only possible through the removal of the end panels (plugs on the sides), determine whether there are microscopic holes on the ends or barely noticeable joints where you can carefully insert the blade.
For an accurate understanding of the design of your model, it is useful to check the table below, which gives common types of mounts for different soundbar series.
| Soundbar model | Type of attachment | Location of screws | Difficulty autopsy |
|---|---|---|---|
| Mi TV Soundbar | Latches + screws | Under the rubber legs | Medium |
| Mi Compact Speaker | Glue + Latches | Absent (hidden) | Tall. |
| Gaming Soundbar | Screws. | Rear panel (open) | Low. |
| Mi Soundbar Pro | Latchers | Under the decorative grid | Tall. |
If you find screws under rubber legs, use a hair dryer to gently unstick them. Don't pull the rubber sharply so as not to deform it. After unscrewing all visible fasteners, check if the screws are left under stickers with a DC-IN port or Optical connector.
The process of opening the soundbar body
The most critical thing is to split the halves of the body, and if the screws are twisted but the body doesn't open, don't use excessive force. Run your finger or shoulder blade along the seam to find the place where the latch holds the strongest. You should start opening the screws at the opposite angle to the power connectors, so that you don't damage the internal cables.
Put a plastic blade in the joint and slowly lead it along the perimeter, hearing the characteristic clicks of the unbuttoned locks. For adhesive models, preheat the seam to a temperature of 60-70 degrees. This will soften the glue and allow the parts to be separated without cracks. The movements should be progressive, without jerking.
☑️ Pre-mortem checks
In some Xiaomi models, the front speaker grid is part of the design and is removed separately. If you feel that the body is not dissipating, check if its screws are kept under the end plugs. Sometimes it is enough to remove the side covers to access the main control board.
- 🔍 Visually inspect the perimeter for hidden screws.
- 🔥 Warm up the adhesive joints (if any) during 2-3 minute.
- 🔓 Start the opening from the angle opposite to the connectors.
- 👂 Listen to the snaps of the latch when pushing the shoulder blade.
⚠️ Warning: Do not use metal knives or screwdrivers to crack the case.The metal slips easily and can pierce the circuit board or damage the speaker membrane, leading to wheezing.
Disconnecting plumes and retrieving electronics
When you remove the back cover, you'll see the soundbar's internal device, and the main focus is on the control board and the wires that go to the speakers, and in most cases, the speaker is connected to the board with two wires (plus and minus) that can be soldered or connected through the JST connector.
If the wires are soldered, you'll need a soldering iron to fully retrieve the board. However, for cleaning or visual inspection, it's often enough to bend the board aside. Be extremely careful with plumes connecting control buttons or LED lights to the main board. They're very thin and easily torn when handled carelessly.
To turn off the connectors, use a plastic blade or nail. Don't pull the wires themselves, just the plastic case of the connector. If the connector has a lock (latch on top), it must first bend upwards.
What to do if the plume is broken?
When you remove the board, pay attention to the condition of the capacitors. Swelling tops or leaked electrolyte indicate a malfunction of the power supply, which is often the reason why the soundbar does not turn on. Also check the soldering quality in places where heavy elements such as a transformer or power connector are connected.
- 🔌 Carefully disconnect the speaker power connectors.
- 📸 Take a photo of the wire connection before disconnecting.
- 🧹 Clean the dust board with a soft brush.
- 👀 Inspect the capacitors for bloating.
Features of disassembly of portable models
Xiaomi portable speakers, such as the Mi Portable Speaker, are more complex because of the battery, and it takes great care to disassemble them because it has a lithium-ion battery inside, and damage to the battery can lead to fire or chemical burns.
Often, these models have screws hidden deep inside, under a layer of glue or under the main grille of the speaker. The grille in budget models often has to be carefully cut or peeled off, which spoils the appearance. So when disassembling portable versions, it is important to have spare adhesive bases or new mesh.
The main board in portable versions is usually compact and mounted on screws to the plastic frame.The Bluetooth module and battery are connected by thin wires. When removing the board, make sure you do not hook or tear off the wires going to the battery, as they often pass through narrow channels.
💡
Use isopropyl alcohol to dissolve the glue under the stickers. It evaporates quickly and does not conduct current, which is safe for electronics.
If your goal is to replace the battery, look for the labeling on the battery itself. Standard sizes often allow you to replace your native battery with an analogue of AliExpress or the local radio market, soldering wires to the old protection board (BMS) or using the original connector.
Assembly and performance check
The assembly is done in reverse order. Before you snap the case, be sure to check the device's health. Connect the power and sound source (Bluetooth or AUX), make sure all channels are working, there are no extraneous noises and wheezing, which will save you time to re-disassemble if you forgot to connect a plume.
When installing the back cover, make sure that the wires do not fall under the screws and are not clamped with plastic latches. A clamped wire can short-circuit or break the contact when vibrating while the bass is running. Lay the cables gently along the walls of the case.
If you used the adhesive to fix the case, let it dry completely before turning on. For screw models, twist them cross-twisted, evenly tightening to avoid skewing the body and slitting.
💡
The basic principle of assembly is that there are no extra parts and the free position of the wires inside the case. No elements should hang around or press the board.
The final step will be to test all the functions: control buttons, display and pairing with the phone, and if the soundbar works correctly, the repair or maintenance can be considered successfully completed.
