How to clean the top speaker on Xiaomi Redmi Note 9 Pro: detailed instructions with a photo

Over time, your Xiaomi Redmi Note 9 Pro speaker may start to sound worse, with wheezing, distortion, or muffled sound, most often due to dust, villi, or small debris entering the top speaker grille (also spoken), and many users try to clean it with improvised tools such as toothpicks, needles, or compressed air, but this can damage the membrane or mesh.

In this article, we'll look at safe cleaning methods that don't damage the hardware of your smartphone, which tools are really effective and which are better not to use, and we'll also talk about how to avoid the typical errors that can cause the speaker to fail permanently, and if the problem persists after cleaning, there's a checklist at the end of this article to diagnose the malfunctions.

Before you start, make sure that the problem is the pollution.

Why is the top speaker clogged on the Redmi Note 9 Pro?

The design of the top speaker (aka spoken speaker) in the Xiaomi Redmi Note 9 Pro assumes the presence of a protective mesh, but it does not always save from small debris.

• 🌫️ Dust and pile — get through the grille when carrying a phone in your pocket or bag, especially for owners who often put the phone down with the screen.
• 💦 Moisture and condensate – even if the phone hasn’t sunk, moisture from the air can settle on the membrane, attracting dust particles.
• 🍟 Fat and dirt – residues from food, creams or cosmetics clog the microholes of the mesh, worsening sound permeability.
• 🔊 Long-term use - over time, any equipment wears out, and the speaker is no exception. If the phone is used for more than 2-3 years, cleaning may be required more often.

It is important to understand that the top speaker in the Redmi Note 9 Pro is responsible not only for the sound during calls, but also for the multimedia playback in mono mode (if the bottom speaker is turned off or clogged), so its pollution affects the overall sound quality.

⚠️ Warning: If the speaker starts wheezing after a phone drop or fluid hits, cleaning may not help - probably damaged membrane or contacts.

What can not clean the speaker: dangerous methods

Many tips on the internet can hurt your Redmi Note 9 Pro more than they help.

• 🧵 Needles, pins, toothpicks -- they can tear the speaker's membrane or bend the safety net, and even if you think you're being careful, the risk of damage is too high.
• 💨 Compressed air (cylinders) - a jet under pressure can not only drive the debris deeper, but also damage the internal components. It is especially dangerous to use cold air - this can cause condensation inside the housing.
• 🧴 Liquids (alcohol, water, WD-40) — Any moisture that gets inside the speaker will lead to corrosion of contacts or sticking of the membrane.
• 🔥 Heating (dryer, battery) – some try to dry the speaker with a hairdryer, but this can warp plastic parts or melt the glue holding the mesh.

Also, don't try to disassemble the phone yourself if you don't have experience. In the Redmi Note 9 Pro, the speaker is soldered to the board, and its dismantling without special equipment almost always ends in damage to the plumes or contacts.

💡

If you do decide to use compressed air, keep the spray at least 10 cm away from the phone and blow at an angle, not directly into the grille.

Safe Ways to Clean Upper Dynamics

Now let’s move on to the proven methods that won’t hurt your Xiaomi Redmi Note 9 Pro. To get started, prepare the following tools:

Soft brush (for example, for makeup or drawing)|Toothpick with blunted end (be sure to wrap the tip with cotton cotton)|Scotch (preferably paint or stationery)|Lantern (for illumination)|Lupa (optional, for accuracy)-->

Method 1: Cleaning with a soft brush

This is the most gentle method that is suitable for removing surface dust:

1. Turn off your phone to avoid accidental tapping.
2. Hold the flashlight at an angle to the speaker - this will help to see the contamination.
3. Carefully run the speaker along the grille (not across) so as not to drive the garbage deeper.
4. For better effect, you can slightly moisten the brush with distilled water (not alcohol!), but then be sure to dry the phone for 1-2 hours.

Method 2: Scotch disposal

This method helps to remove villi and fine dust that stuck to the net:

1. Cut a small piece of tape (no more than the width of the speaker grille).
2. Apply it to the speaker with a sticky side down and press it slightly.
3. Take the tape off in a sharp move, the garbage should stay on it.
4. Repeat 2-3 times, using a new piece each time.

This method is especially effective if hair or threads get into the speaker.

Method 3: Toothpicking with cotton wool (for persistent contaminants)

If the garbage is tightly entrenched in the grille, you can use a toothpick, but with caution:

1. Wrap the tip of the toothpick with a thin layer of cotton (it should be tightly fixed).
2. Slightly moisten the cotton wool with distilled water (don’t drip on your phone!).
3. Carefully run the speaker on the grille without pressing - cotton will collect dirt.
4. Dry the phone in a vertical position for 1-2 hours.

⚠️ Attention: If the sound gets worse after cleaning or there's a crack, you accidentally shoved the garbage inside the speaker.

How do you check if the cleaning has helped?

Once the speaker is cleaned, you need to evaluate the result, and you can do this in several ways:

If there's no improvement after cleaning, maybe the problem isn't the pollution, it's the hardware malfunction, and then just replacing the speaker will help.

💡

If the sound is perfect after cleaning, but after 1-2 weeks the problem returns, then the garbage enters the phone from the outside. Check the case or bag in which you carry your smartphone: perhaps there is pile or sand accumulating there.

What if the speaker doesn’t work after cleaning?

Sometimes, after cleaning yourself, the speaker stops working altogether, and this can happen for several reasons:

• 🔌 Contact damage – if you pressed too hard on a toothpick or brush, the speaker plume could come off.
• 💧 Moisture intrusion – even drops of distilled water can cause corrosion if the phone is not dried.
• 🔊 Garbage deepening – if dust particles penetrate the membrane, the speaker can “jam".
• 🛠️ Software failure is rare, but it happens that after physical exposure, you need to restart or reset the sound settings.

Here's what we can do:

1. Restart your phone – sometimes it helps to restore the speaker.
2. Check the sound settings: Go to Settings → Sound and Vibration → Sound Quality. Make sure that Mono Sound or Sound Amplification mode is not activated.

Reset the sound settings

Settings → System and device → Resetting settings → Resetting sound settings

Prevention: How to protect the speaker from pollution?

To avoid having to clean the speaker every few months, follow these tips:

• 📱 Use a speaker-protected case – some models have special “sponges” or protrusions that prevent dust from getting in.
• 🧼 Regularly wipe the phone – just once a week to remove dust from the body with a microfiber wipe.
• 🚫 Do not put the phone down with the screen – especially on soft surfaces (sofa, bed) where pile accumulates.
• 💼 Carry your phone in your own pocket – not with keys, coins or other items that could scratch the grille.
• 🌧️ Avoid humidity – Do not use your phone in the rain or in the bathroom (even if it has protection). IP53).

In the Redmi Note 9 Pro, the top speaker is located next to the infrared port, so it is important not to touch it when cleaning.The IR port is sensitive to mechanical stress and can fail if you accidentally press it with a toothpick or brush.
