Why does the charging strap earphones have an electric current sound?

Because when charging, a large current passes through the data cable and enters the mobile phone, which will generate a magnetic field and interfere with the signal of the earphone, so there will be noise, or it may be that the mobile phone has some slight leakage and interferes with the signal of the earphone. The charger is a high-frequency switching power supply with high-frequency components in series into the power circuit, so there is noise when heard.

Solution: Remove the microphone reinforcement. Because some sound cards don't support it. Optional mobile phone headphones.

Buy original headphones.

Extended Information: Precautions for Using Headphones:

1. When using the earphones, don't pull hard, wear them gently.

2. Try not to use the earphones in the rain, so that the acidic substances in the rain may cause the earphone cable to age prematurely or even be damaged.

3. For walking, cycling and other sports with little activity, users can wear ordinary in-ear headphones.

Remember to make an earbud cover on the earbuds to prevent the earphone eraser from aging.

4. After the earphones are used, they should not be "rolled" on the Walkman, but should be put into the box or bag that the earphones are equipped with. If it's a headset, you can use a bag the size of a CD player to store it, which also prevents scratches on the case of the headset to some extent. It's best to put some desiccant.

Prevent rubber from aging and deforming.

Because the charger is a high-frequency switching power supply, there are high-frequency components connected to the power supply circuit, and noise is heard.

As follows:

1. There is a possibility that the mobile phone has a headphone port current problem, which is a hardware problem of the mobile phone, and the earphone can be replaced for inspection.

2. It may be that the headphone jack is not plugged in properly, you can rotate the headphone plug to detect.

3. It may be that there is a problem with the earphone line, which is generally damaged due to the old line due to wire entanglement, and generally appears at the back end of the plug and can shake the earphone cable and the plug connection part for detection.

From the perspective of the development of the entire audio industry, wireless headphones are still a new thing, the development time is not long, in the rising period, user demand continues to improve, and users' expectations for wireless headphones are also increasing, which is a new test for the industry. Some of the key points that users are most concerned about include sound quality, battery life, wireless transmission capability, and data transmission latency.

From the data point of view, the wireless transmission capacity can basically meet the needs of the vast majority of users, and the sound quality and battery life still have great potential for improvement.

First, the cause of the failure:

1. The headphones are not compatible;

2. The mobile phone is not cleaned up in time, too much system garbage is piled up, and the mobile phone is slow to reflect, so the system garbage and anti-virus of the mobile phone should be cleaned up in time;

3. If the headset is damaged, you can compare the headset with other headsets and replace the headset if necessary;

4. Whether the microphone is in a strengthened state;

5. Whether the mobile phone is charging, the quality of the mobile phone is too poor or the sensitivity of the earphones is too high, and this situation will occur when charging.

Second, the solution:

1. If the earphone jack is not plugged in properly, you can rotate the earphone plug to detect.

2. There is a possibility that the mobile phone has a headphone port current problem, which is a hardware problem of the mobile phone, and the headset can be replaced to check, 3. There is a problem with the headphone line, which is generally caused by the old damage of the line due to the winding of the wire, and it generally appears at the back end of the plug to shake the headphone cable and the plug link part of the detection.

4. The problem of the earphone itself, which may be the current sound caused by the surrounding electromagnetic radiation, or it may be the current sound of the poor performance of the earphone itself.
