After a period of use, the smartphone speaker will get dust, lint, and other types of dirt that you cannot see with the naked eye. If it is not cleaned for a long time, it will make a hissing sound. However, before going to the repair shop, you can try a few methods to clean the speaker phone inside and out.
Steps
Remove dirt from speakers with household items
- Note other speaker locations, such as next to the volume buttons or at the bottom of the front of the phone.
- Change cotton swabs when they get dirty.
- Rotate the clay so you can always use its clean surfaces.
- Buy sticky clay from stationery stores or online distributors.
- Raise the brush and use the stiff bristles to scrub stubborn dirt.
- Always use a medium brush, because a soft brush won’t be strong enough to remove dirt, and a stiff brush is too thick to get into the small speaker holes.
Blowing dirt with compressed air
- Buy a can of compressed air with a straw to increase accuracy.
- Tighten the suction hose if you notice compressed air leaking on either side of the nozzle.
- Skip the straw if you’re comfortable spraying compressed air without using it.
- Do not blow too close to the speaker; otherwise, the electronic components inside the phone may be damaged.
- If you use a straw, hold the straw with your non-dominant hand to hold it in place when blowing air.
Clean the speaker from the inside
- You can buy a part plow at home appliance stores, which is a tool with a flat, wide screw head that is used as a wedge.
- If you find it difficult to pry, increase the heat to heat the phone case frame to melt the glue that holds the back cover in place to the phone case frame.
- With older and cheaper phones, you can pry the back cover off by hand. For newer and more expensive phones with glass backs, you can’t do that.
- Gently pull the speaker out using a tool pry if it is difficult to remove.
- You can also use a soft cloth or lint-free paper towel. However, they are not very effective at absorbing dirt.
- Make sure to let the speaker strip and speaker hole dry before placing the speaker back into the machine.
- Remove the plastic film on the screw if your phone has one.
- After removing the auxiliary back cover, you can touch and clean the grooves and speakers. However, in some cases, you will only be able to clean the grooves on the speaker.
- Insert the auxiliary back cover once the speaker cleaning is complete and tighten the screws. You can then attach the metal case to the speaker and close the back cover.
Things you need
- Cotton swab
- Sticky Clay
- Medium toothbrush
- Compressed air tank (with suction tube for added accuracy)
- Suction cup
- Components pry rod
- Phillips screwdriver size #3 (10 cm)
Advice
- If the speaker still malfunctions after cleaning, take the phone to a repair shop.
- Each phone line will have a different design, especially with newer models. No matter how it’s designed, don’t break any wires or cables, and don’t do things you’re not sure about. A working phone is better than a dirty phone!
