Why is there a buzzing sound in the headphones?

1. Try using another headset. If the buzzing sound disappears, it means there is a problem with the headset.

2. Plug in the headphone in question and twist the headphone wire with your hands. If the buzzing sound changes, it means the wire is broken, resulting in poor contact. Take the earphones apart and use a soldering iron to solder the broken ends.

3. If there is no response when twisting the wire, then turn the plug of the headset again. If the buzzing sound changes, it means that the plug contact is not good. You can use fine sandpaper to gently wipe away the rust stains or use a special The metal cleaning effect is better.

4. If the buzzing sound persists after changing headphones, it means there is a problem with your system settings. Open the sound card control panel and select None under the sound effect item, and select noise suppression under the microphone effect item.

Headphones (Earphones; Headphones; Head-sets; Earpieces) are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into listenable signals using speakers close to the ears. The sound waves arrived. Headphones are usually detachable from the media player and connected using a plug. The advantage is that you can listen to the sound alone without disturbing others; it can also isolate the sound of the surrounding environment, which is very helpful for people who use it in noisy environments such as recording studios, DJs, traveling, and sports. Earphones were originally used for phones and radios, but with the popularity of portable electronic devices, earphones are mostly used in mobile phones, Walkmans, radios, portable video games and digital audio players.

From the perspective of the development of the entire audio industry, wireless headsets are still a new thing. They have not been developed for a long time. They are still on the rise. User demands are constantly increasing, and users’ expectations for wireless headsets are also increasing. , this is a new test for the industry. At present, the key points that users are most concerned about include sound quality, battery life and wireless transmission capability. From the data point of view, wireless transmission capability can basically meet the needs of the vast majority of users, while sound quality and battery life still have great potential for improvement. If we start with these two points to improve it, I believe it will easily attract users’ attention in the future.

Headphones are a symbol of people’s portable audio. Mobile phone headsets are divided into two standards: OMTP standard is usually called national standard, and CTIA is called international standard. Earphones are classified according to their energy conversion methods, mainly including: dynamic coil method, moving iron method, electrostatic type and isomagnetic type. From the structural and functional classification, it can be divided into semi-open and closed types; from the wearing form, it can be classified into earbud type, ear-hook type, in-ear type and head-mounted type; from the number of wearers, it can be classified into single earphone and Multi-person headphones; based on the sound source, they can be divided into active headphones and passive headphones; active headphones are also often called plug-in headphones.

The price of headphones ranges from a few yuan to hundreds of thousands of yuan. The ordinary price is generally around 20 yuan, and the slightly better price is around 400 yuan. If it is a headset, the price is usually higher. some. Top-quality headphones, such as limited-edition headphones produced by some top brands, can cost tens of thousands of yuan or more.

How to solve the problem of buzzing sound in headphones?

Solution: The design solution is to add a tuning vent. When the headphones are inserted into the ears, the air pressure is discharged from the vent. This cannot be changed after the headphones are purchased. You can use Memory foam earmuffs can be pinched flat and inserted into the ears. They will then rebound naturally and wear securely. This way, air pressure will not be pressed into the earphones and can be relieved.

1. Cause analysis: The unit and the front cavity of the earphones are sealed, and there is no tuning vent. After being inserted into the ears, the air pressure directly acts on the diaphragm, and the diaphragm produces a deformed sound, similar to the wrinkles of plastic. sound.

2. Note: For headphones with this condition, when wearing or taking them off, try to avoid inserting them into the ear canal or pulling them out quickly. In this case, the air pressure force will be too strong and the diaphragm may be damaged. , should be as slow as possible.

3. Additional points: When the rubber head is inserted into the ear, after the headphone rubber head is sealed with the ear hole, the airflow in the ear pushes the diaphragm of the headphone speaker to produce a sound. This indicates that your headset is The sealing performance is very good, and the sound is very loud when playing music.

After plugging in the earphones on the phone, there is always a buzzing sound in the earphones. What is going on?

There may be the following reasons:

1. The sensitivity of the headset is too high, and a very small audio voltage can push it.

2. The shielding wire of the earphones has fallen off, or there is no shielding wire at all. The shielding wire should completely wrap the signal wire with a braid, instead of using an ordinary single-core ground wire. Replace;

Solution:

1. Change to headphones with lower sensitivity and higher impedance;

2. Change the signal cable of the headphones to one with The shielded wire is a mesh braided signal wire;

3. Find a friend who knows electronics and welding to connect a 683 or 104 ceramic capacitor between the left and right channel signal wires and the ground wire.

4. If there is no problem with the headset on another mobile phone, it means that the phone has a plug-in or sound effect software turned on, and it will be fine after restarting.

If you use vivo’s Bluetooth headset and there is noise or lag in the Bluetooth headset, you can refer to the following solutions:

1. Confirm whether it is a problem with the audio source. It is recommended to change to other music/videos. Play it and see;

2. Put the two earphones into the charging box and close the lid, then reopen the lid and try to connect and play music again;

3. Enter Bluetooth on your phone On the settings page, in the paired device, cancel the pairing, then put the earphones into the charging box and open the lid. Press and hold the function button for 2 seconds. When the white indicator light continues to flash, the earphones enter the pairing state. After pairing, play again. Try music;

4. Put the earphones into the charging box, keep the charging box open, and then press and hold the function button on the charging box for 15 seconds until the orange light flashes quickly and release the button. When the headset is restored to factory settings, after the factory reset is completed, the headset will automatically enter the pairing state, and try again after pairing;

5. If there is still noise from the headset after operating the above method, you need to bring the headset and If you have a valid purchase voucher, go to the vivo customer service center for inspection and processing. You can follow the WeChat official account "vivo" or "vivo customer service" to check the service center address and phone number. It is recommended to call before going to ensure that there is a staff member to receive you before going there to avoid wasting valuable time. , a trip in vain.
