If you like this article, just "like" and "pay attention". Everyone who is beautiful cares. What are you waiting for?

Nowadays, many people like to use headphones when watching TV, listening to music and chatting by voice on their smartphones. The speaker that comes with the mobile phone is released, which makes many people slowly ignore it. Many people will wonder why the speaker of mobile phone is getting louder and louder, and sometimes they can't even hear each other's voice. What's going on here?

The reason why mobile phone speakers become smaller.

1, the hole of the mobile phone speaker is blocked.

There will be many holes in the mobile phone speaker, just to let the sound spread better. However, the long-term use of the mobile phone will let dust enter the speaker of the mobile phone, and even cause these small holes to be blocked. Its principle is the same as that of computer dust removal, and mobile phone dust will also have an impact when it enters the speaker.

Solution: Disassemble the machine and clean up the dust. Open the back cover, remove the screws, tear off the back cover inside, tear off the dust screen inside the speaker and microphone, and clean up the installation, so the sound will be much louder.

2. The speaker itself is damaged.

Nowadays, smart phones are getting thinner and thinner, and mobile phones can't stand our bumps. As soon as the mobile phone hits the ground, our screen may be broken. However, when all our attention is focused on the screen, we may inadvertently damage the speaker, and the position of the speaker is often the position where the mobile phone is descending.

Solution: If the coil inside the speaker is in contact with the permanent magnet, the coil can't vibrate, so it can't produce sound or the sound is weak, so you can only change the speaker, or the gasket between the speaker and the motherboard is in poor contact, so you just need to disassemble the phone and install the speaker.

The mobile phone system is out of order.

When our mobile phone downloads some rogue software, these software will automatically bind to our mobile phone system, which will lead to errors in mobile phone operation and hardware problems. Sometimes the sound of the speaker is low because our mobile phone system is incompatible with the software, which leads to the wrong internal parameters.

Solution: If it is a system problem, it is recommended to clean up rogue software or brush the machine to deal with it. According to many similar maintenance situations, the speaker volume caused by the mobile phone system is too small to be used normally, and it will return to normal after brushing the mobile phone.

4, mobile phone water damage speakers.

After the phone falls into the water, the water outside the phone is easy to handle, but the water entering through the speaker hole is more difficult. The most troublesome thing is that the speaker is the first to be affected and damaged after the mobile phone enters the water. There is no sound at all after entering the water, no matter how loud it is.

Solution: When the mobile phone is flooded, first shake the mobile phone vigorously and throw out the water that has entered it. Then use a hair dryer (alternating cold air/hot air) to blow at the speaker hole of the mobile phone to dry the water in the mobile phone.
