What should I do if the voice of my mobile phone becomes smaller?

There are six solutions to the low voice of mobile phones.

Method 1: Adjust the volume.

In the mobile phone settings, set the settings such as mobile phone * * *, alarm clock * * *, voice call and media volume to the highest level, and try them one by one to see which part is out of order.

Method 2: Hardware failure

(1) When we are on the phone, we can turn the volume button on the outside of the phone to the highest level. At this time, if the sound of the mobile phone is still very low, it may be that the handset is broken and needs to be replaced.

(2) If the sound is very low when you play the speaker, or when the mobile phone plays songs, it may be that the external speaker is broken and needs to be replaced with a new external speaker.

(3) If someone can't hear me on the phone, it may be that the microphone of the mobile phone is broken. At this time, the microphone of the mobile phone needs to be repaired to ensure the normal use of the mobile phone.

Method 3: Software conflict

The software installed on the mobile phone conflicts. It may be that the third-party software you downloaded recently caused the volume of your mobile phone to decrease. At this time, it is necessary to uninstall the recently installed software and restart the phone. It is best to detect the voice of the mobile phone.

Method 4: System failure

System failure can also lead to a low voice of the mobile phone, so make a backup of the mobile phone first. Then enter the phone settings-restore the factory settings and try again.

Method 5: Install the software.

(1) You can try to install third-party volume enhancement software, such as "Volume+".

(2) Download and install it on the mobile phone, and then adjust the volume.

Method 6: Mobile phone maintenance

If all the above methods fail, or can't be handled now, then after-sales maintenance is the best choice.

The above are six solutions to how to deal with the low voice of mobile phones. I hope the above sharing can help you solve the problem of low voice on your mobile phone.

2. Why does the sound of Android phone suddenly become smaller?

1, software problem. The mobile phone has built-in voice control settings, one is the telephone volume control of the system; Second, the volume control of the system interface operation prompts, such as ringing, various prompts, etc. The third is the volume control of the APP application calling system. They are independent;

2. Turn up their slider-pull volume control, which can usually solve the sound control problem in the corresponding use. The system has no options for installing and uninstalling drivers or applications related to the volume for users to modify and debug. So if you suspect that it is a system problem, brush the machine to verify it.

3. Hardware problems. After the mobile phone enters the water, the related equipment is injured. For example, horn damage, cable desoldering, related circuit module desoldering, volume micro button deformation, all of which may cause quality problems and have to be sent for repair.

Mobile phone speaker is an electroacoustic device that converts electric energy into acoustic energy, which is simply a sound generator.

There are many kinds of speakers. Although the working methods are different, they all push the surrounding air by generating mechanical vibration, which makes the air medium fluctuate, thus realizing the conversion of "electricity-force-sound".

3. What causes the speaker sound of mobile phone to decrease?

Reason: 1. Dust accumulation on hand-held phones 1. When the receiver appears in a dusty place for a long time, dust will be deposited on the receiver, so we should clean the receiver every once in a while, just as we need to clean our ears often.

2, cleaning methods can be used to fiddle with the dust near the receiver to make it loose and fall off, or you can gently wipe it with a toothbrush, different mobile phone methods are diversified. Second, the mobile phone hardware is damaged or aging 1. Mobile phone hardware will inevitably age after being used for a long time. Because we often use mobile phones, all kinds of water vapor and liquids often erode the handset, and the hardware will naturally age.

2. If the physical method can't be solved at this time, it is necessary to measure whether it is necessary to spend money to replace the receiver. Of course, the sound of some mobile phones becomes smaller. It may be that the external speaker of the mobile phone is damaged, so hands-free and extremely low music playback often occur.

4. If others say that our phone calls are very low, it may be that there is something wrong with the microphone of the mobile phone. Therefore, the voice of the mobile phone becomes smaller, and it is necessary to find the key to the problem in order to better prescribe the right medicine.

5. For all kinds of hardware damage or damage, you can check the audio driver of the mobile phone first, or download the audio driver test again in the mobile phone official website. If the method fails, it is recommended to consult professional maintenance personnel.

Third, the influence of software APP is influenced by software. Generally speaking, it is caused by the built-in voice control settings of the mobile phone: 1, the telephone volume control of the system; 2. Volume control of operation prompts in the system interface, such as * * *, various prompts, etc. 3. The 3.PP application calls the volume control of the system, which is independent. 4. If the sound becomes smaller sometimes, it may be related to the compatibility between APP software and mobile phone.

Because some software has the overbearing function of changing the sound of the mobile phone, if the mobile phone really can't find the reason why the sound is getting smaller, you can consider trying to delete the suspicious software to test the reason. Fourth, system error, failure 1, mobile phone system error, sometimes affecting the sound. At this time, you can try to restart your phone first. If the phone is useless after restarting, you can activate the second measure and solve it by restoring the sound settings. Ordinary Android phones have advanced settings, so you can reset or restore the phone at this time.

2. However, some mobile phones have no reset or recovery function. At this time, we can make a backup on the mobile phone and then restore the factory settings in the mobile phone settings. Generally speaking, if the sound of the mobile phone suddenly decreases, it is probably because of our habit of using the mobile phone, so we should clean the handset more, pay attention to the maintenance of the mobile phone, and prevent it from falling. After all, mobile phone devices are still easy to drop.

Extended data mobile phone speaker: 1, simply speaking, sound! It is an electroacoustic device that converts electric energy into acoustic energy. There are many kinds of speakers. Although the working methods are different, they all push the surrounding air by generating mechanical vibration, which makes the air medium fluctuate, thus realizing the conversion of "electricity-force-sound".

2, mobile phone speakers are divided into mono, dual channel, stereo three parts! In mono audio equipment, only the front and back position, timbre and volume of sound and music can be felt, but the lateral movement of sound from left to right can not be felt. Generally speaking, there are two channels, and the electrical signals they transmit are often different in the circuit. In the process of pursuing stereo, electroacoustic scientists only used dual channels at the earliest due to technical limitations, so stereo and dual channels seem to be the same thing.

What is the reason for the sound of 4.4? OPPO mobile phone suddenly becomes smaller?

It may be caused by dust on the receiver, software conflict, mobile phone problems, etc. When the sound of the mobile phone suddenly drops, you can try the following methods.

1, adjust the volume of the phone.

Press the Volume+key directly to set the volume of the mobile phone to the maximum. Or open the settings, enter the volume setting option, turn all the volumes to the highest level, and then open the media library for audition to see if there will be any response.

2, restart the phone

If the volume button has been turned to the maximum and there is still no sound on the phone, you may wish to restart it. Generally, the volume will be restored after restarting, but in some cases, the volume will be reduced after a short interval.

3. Restore factory settings

Sometimes there are problems in the system, which will lead to various problems in the mobile phone, so if there is no important data and information, you can choose to restore the factory settings. Alternatively, you can make a backup before restoring the factory settings.

Step 4 remove dust

When the mobile phone is used in a dusty place for a long time, it is easy to deposit dust near the receiver. Therefore, we need to clean the mobile phone every once in a while. We can use toothpicks to fiddle with the dust near the receiver to make it loose and fall off, or we can gently wipe it with cotton swabs to reduce the volume jam of the mobile phone.

5. Software conflict

Sometimes the sound becomes smaller, which may be related to the compatibility between APP software and mobile phones. Now many software will change the original volume, which is quite overbearing. You can think about what software you downloaded recently. If you are not sure, you can set permissions on all the software at the mobile phone housekeeper's home and delete it directly.

6. Upgrade the system

Sometimes, the size of the system sound is also related to the system version. I used a mobile phone before, but I just bought it, and the sound is very low. No matter how I adjust it, I can't adjust the volume. Finally, after upgrading the system to the latest version, I found that the voice of the mobile phone was much louder. So the system * * * is also a factor that determines the sound of the mobile phone.

7, inspection and maintenance

It is inevitable that the mobile phone will encounter the problem of hardware aging after being used for a long time, which cannot be solved by physical methods. For all kinds of hardware damage or damage problems, you can consult professional maintenance personnel to see if they can be solved.

5. What if the volume of the mobile phone is turned to the maximum or the sound is very low?

Small voice reason

The microphone is broken.

Component leaks or variable values.

Reweld or replace audio (power supply, CPU).

Increase the working voltage of microphone (MIC).

Low noise solution

Check whether the equipment microphone is blocked.

Check whether the "mute" function on the call interface has been clicked.

Try to change the location (rule out whether it is a network problem).

If your mobile phone supports noise reduction, it is recommended to cancel the noise reduction attempt. Operation: standby interface-phone-menu key-call setting-noise reduction-uncheck.

If it is invalid, back up the data and restore the factory settings of the mobile phone (Settings-Reset-Restore Factory Settings).

6. The mobile phone is getting louder and louder. What happened?

Turn down the volume of the call. If you mean handset mode, that's normal, because handset mode will be considered when designing mobile phones. Most people put their ears close to each other to avoid damaging people's hearing. Even the loudest sound in receiver mode is not as good as the sound played outside.

If it is in playback mode, but it becomes smaller, first of all, it depends on the volume setting of the mobile phone. Many "other volumes" of mobile phones belong to "media volume" and mobile phones belong to "call volume", which are controlled by two (or more) volume controllers, as shown in the figure. You can look inside the volume setting instead of just pressing the volume plus volume minus these two hardware, and everything will be fine.

7. What's the matter with my mobile phone getting louder and louder?

Sometimes you will find that the sound of your mobile phone suddenly becomes small and annoying. So what's the matter with the sudden decrease in the sound of the mobile phone? Below I will introduce the reasons and solutions for the low voice of mobile phones. Let's have a look.

Methods/steps

Set the mobile phone * * *, alarm clock * * *, voice call and media volume to the highest level in the mobile phone settings, and then try one by one to see which part is out of order.

When making a phone call, turn the volume button on the outside of the phone to the highest level. If the sound is still low, it may be that the handset is broken.

If your voice is low when you speak through the speaker and play songs on your mobile phone, the speaker may be broken.

If others can't hear me on the phone, it may be that the microphone of the mobile phone is broken.

Software conflict, it may be that your recently downloaded third-party software caused the volume of your mobile phone to decrease. Uninstall the recently installed software, and then restart the phone.

If the system fails, make a good backup of the mobile phone first, and try to enter the mobile phone settings-restore the factory settings.

8. Why is the sound of mobile phone listening to music suddenly low, even if it is turned to the maximum?

I suggest you try this:

1. Check whether the volume in the music software is adjusted to the appropriate position.

2. Dust off the speaker of the mobile phone.

Because this situation is often covered by the dust inside the mobile phone, sometimes the same happens to the microphone, resulting in the inability to hear the other party's voice during the call.

There are usually two kinds of dust removal methods:

1. There is special dust removal software in the mobile phone, which makes the dust fall off through sound wave vibration. However, due to the limited volume, the dust removal effect is not good, and it is generally used when there is only a small amount of dust.

2. Disassemble the machine for dust removal. Because you can see the inside of the mobile phone, this method has a good dust removal effect. However, disassembly also has certain risks.

Note: Do not disassemble the machine without knowing the disassembly steps! At present, the internal module of mobile phone is highly integrated, and it is easy to destroy the internal structure if it is forcibly disassembled. You can choose to send the machine to the outside repair shop and pay a certain fee to let them help you complete the dust removal, which is relatively safe.
