Simple Ways to Clean Your Phone Speakers and Make Them Sound Louder

Trying to listen to a voice message, watch a video, or take a phone call on speakerphone only to realize the sound coming out of your smartphone is incredibly muffled, quiet, or crackly is deeply frustrating. You find yourself turning the volume buttons all the way up to maximum, but the audio still sounds like it is buried underwater. This annoying sound drop rarely means your physical speakers are blown out or broken. Instead, your phone's tiny acoustic grill meshes are almost always just choked shut under a thick layer of hidden pocket lint, dirt, and earwax.

You can easily clear out the debris and restore your phone's original crisp, loud sound using these three quick steps:

Step 1: Use a Dry, Soft-Bristled Toothbrush to Scrub the Speaker Grills

The safest and most effective tool for cleaning out packed pocket lint from your phone's audio slots is a clean, completely dry toothbrush with soft bristles. Hold your smartphone with the speaker grills facing downwards so that any loosened dirt falls out out of the device instead of sliding deeper inside the frame. Gently scrub the bristles back and forth across the speaker meshes at a slight angle. The fine hairs of the toothbrush will slide into the tiny acoustic holes, hooking onto lint clumps and pulling them out cleanly.

Step 2: Clear Out Packed Earwax Using a Wooden Toothpick Very Gently

If you look closely at your phone's top ear-speaker slot and see a shiny, solid layer blocking the mesh, you are dealing with packed earwax from holding the phone against your face. A toothbrush cannot break this layer loose. Take a sharp wooden toothpick, hold it almost completely flat against the screen to avoid poking straight into the delicate speaker material, and very gently scrape the wax out from the edges of the slot. Take your time, and never push the point of the toothpick deeply into the grill holes, or you risk puncturing the underlying acoustic membrane.

Step 3: Play a Low-Frequency Sound Wave to Eject Trapped Moisture

If your phone speaker started sounding muffled right after you used it in the rain, took it into a humid bathroom, or dropped it in water, a tiny droplet of moisture is trapped inside the audio chamber. The surface tension of the water blocks the speaker cone from vibrating freely. You can force the water out using pure physics. Open your mobile web browser, search for a free online tool called "Fix My Speakers" or open a video player and search for a "165Hz speaker cleaner sound wave." Playing this high-volume, low-frequency buzzing tone creates intense air pressure inside the speaker chamber, physically blasting the trapped water droplets out of the grills.
