How to clean the dust on the phone speaker?

Here's how to clean up your phone's speaker:

Mobile: Huawei Mate40Pro

System: <>2. Click the speaker cleanup button on the interface that opens.

3. Open the button behind the automatic cleaning in the interface, turn up the volume of the mobile phone, and repeat it once or twice to clean the ash.

Introduction to mobile phone speakers

A mobile phone speaker is an electroacoustic device that converts electrical energy into sound energy, which is simply a sounder and a mobile phone speaker. There are many types of loudspeakers, and although they work in different ways, they all ultimately generate mechanical vibrations to push the surrounding air, causing fluctuations in the air medium to achieve the conversion of electrical sound.

The mobile phone speaker is divided into mono, two-channel, stereo three parts, in the mono audio equipment, you can only feel the sound, the front and back position and timbre, the volume of the volume, and can not feel the horizontal movement of the sound from left to right.

Generally speaking, there are two sound channels, and the electrical signals they transmit are often different in the circuit, and electroacoustics in the process of pursuing stereo sound, due to technical limitations, only used binaural channels in the earliest days, so stereo and binaural sound seem to have become one thing.

Before 1958, the way people recorded and advanced audio was still mono. Mono refers to mixing audio signals from different directions and recording them with a recording device, and then replaying them by a loudspeaker. The effect of the replay is simplistic and distorted compared to the real natural sound.

The steps to clean up the dust from the phone horn are as follows:1. Find Settings on the desktop of your phone and click Settings.

4. After entering the speaker cleaning page, turn on automatic cleaning.

5. The start prompt pops up, click I know.

Introduction of mobile phone speakersMoving-coiled. The basic principle comes from Fleming's left-handed law, if a wire with current and magnetic field lines are placed perpendicularly between the north and south poles of the magnet, the road line will be moved by the interaction between the magnetic field lines and the current. More than 90% of the cone cells are dynamic designs.

Electromagnetic. A movable iron chopping plate (armature) is erected in the middle of a U-shaped magnet, and when the current flows through the coil, the armature will be magnetized and the magnet will cause repulsion, and at the same time drive the diaphragm to move. This design is inexpensive but not effective, so it is mostly used in ** tubes and small headphones.

Inductive. It is similar to the electromagnetic principle, but the armature is doubled, and the two voice coils on the magnet are not symmetrical, and the two armatures will push each other for different magnetic fluxes when the signal current passes. Unlike electromagnetism, inductance can reproduce lower frequencies, but the efficiency is very low.

If the mobile phone has been used for a long time, due to static electricity and daily use, it will be found that the microphone and speaker have serious dust, but ordinary consumers do not have professional tools, so it is impossible to disassemble and clean up the phone by themselves. A simple method of cleaning the ash, only one section can be cleaned.

Although I don't feel like it has much impact on daily use, I always feel psychologically uncomfortable. If there is too much backlog, it will also clog the speaker and make the phone less sound. Tap on the audio file and turn up your phone's volume to the maximum to start dusting your phone's speakers.

** When the horn hole has a strong sense of vibration. The principle is very simple, that is, through a specific sound wave vibration, some fine dust will automatically fall, and some dust stuck to the horn hole can be cleaned up. Of course, the dust cleaned out is also very fine, and a lot of dust is naturally invisible to the naked eye.

Precautions1. Some dual-speaker mobile phone earpieces can also produce sound, so this method can also clean the earpiece.

2. Remember to wipe it with a wet paper towel after the cleaning is completed.

There are the following ways to solve it:

1. Use a needle to pick out the dust in the handset and speaker of the mobile phone, and then suck out the dust from the thing that is blown down or inhaled with slight force.

Note: Improper operation of this method will damage the parts of the phone.

2. Go to the after-sales or maintenance office and let a professional person help you disassemble the machine and clean the ash. It is not recommended to disassemble it yourself, because it is very likely to break the phone without experience.

Usually we put the mobile phone in the trouser pocket or bag, and the trouser pocket or bag usually has some fine dust, after a long time, the speaker and microphone on the top of the iphone are full of all kinds of dust, because it is a filter, so it is a headache to clean up, today I will talk about how to clean up this dust.

1.Find a piece of double-sided tape (transparent glue is also acceptable, but you have to find a particularly sticky one) and tear it into a band.

2.Attach the double-sided tape to the microphone or speaker and smooth it out.

3.Peel the double-sided tape off and you'll see a lot of dust stuck to you that you didn't notice before.

4.Finish the day.

Precautions: Pay attention to clean up the dust, and never use sharp objects to poke the dust on the microphone or speaker, otherwise the more you poke in, the more you will have to disassemble the machine.
