After putting on the big headphones, listen to the person next to you or the voice will be amplified

My circuit is relatively poor, I said the wrong everyone corrected, the principle of the headset is the current input sound output, take the dynamic headset as an example (most of the headphones are dynamic headphones), the current signal is amplified, filtered, rectified, into the coil in the permanent magnetic field, due to the principle of electromagnetic conversion, the coil in the magnetic field will vibrate due to the change in the strength of the current, and then drive the diaphragm connected to it to produce mechanical vibration and sound, the relevant schematic diagram, the circuit diagram is as follows, it can be seen that unless your classmate is particularly loud, The amplitude can still resonate with the diaphragm after being greatly reduced by ABS earmuffs, sound insulation cotton, etc., of course, I believe that it is impossible for ordinary people to do this, because this has been taken into account at the beginning of the design, or, your classmates are emitting high-frequency radio frequency signals that affect the headphone circuit current, it is recommended that you report to the organization to retain talents for us, ps; Human voice frequency: 60-1200Hz, common RF model frequency: 100,000Hz or above.

1.There is no such thing;

2.Your description is quite similar to that of a moving iron hearing aid;

3.The reason why the headphones are made into a head-mounted airtight design is to isolate the noise of the external environment, and the same is true for the airtight in-ear plugs;

4.If it's like you said, how can you appreciate it?!

Did your headphones take a microphone and you turned it on again?

It depends on what kind of headphones you are using, for example, the in-ear type is better than other sound isolation. Many headphones are basically labeled on whether they can isolate from outside sounds, such as noise-canceling headphones.

In-ear headphone sound isolation:

1. Reduce the interference of external noise to the world.

2. Provide a closed environment, which greatly reduces sound leakage. From a practical point of view, that is, in a noisy environment; You can enjoy it at a relatively low volume without being affected**.

3. Increase the texture and volume of low frequency.

4. Increase the performance of the most detailed details of these headphones, the catheter of these headphones will be connected to the ear tips and inserted into the front half of the ear canal, thus creating a sealed listening environment. And many high-end in-ear headphones will even customize the eardrum for the customer to provide the best comfort and perfect sound isolation.

There are two main types of noise-cancelling headphones:

Active noise cancellation and passive noise cancellation.

First of all, let's talk about the simple principle of passive noise reduction, passive noise reduction is simply sound insulation. It is to isolate noise as much as possible through the sound insulation material or special structure of the earphone. However, these headphones can only block high-frequency noise, and are helpless against low-frequency noise reduction.

Active noise cancellation is to neutralize the noise by generating a reverse sound wave equal to the external noise through the noise reduction system, thereby reducing noise. This kind of headphones are equipped with a special noise reduction circuit, generally through the audio receiver (such as a micro microphone) and the anti-noise output chip, by receiving, analyzing the frequency of external noise and generating the opposite frequency, weakening or canceling each other, so as to achieve the purpose of shielding noise.

Summary. That's because there is ** sound in your headphones, and if the outside world is loud, it will indeed have a certain impact, but it shouldn't last long, try to wear less headphones, and if you have more headphones, it's not good.

Hello, what kind of situation have you encountered, is someone talking loudly into your ear, and your ears are uncomfortable?

Ear shaking is uncomfortable.

That's because there is ** sound in your headphones, plus the outside world is loud, there will indeed be a mold height fixing collapse sound, but it shouldn't last long, try to wear less headphones, more headphone belts, it's not good.

Is that okay without headphones?

Try to wear as few headphones as possible, why do you need to wear headphones?

Play the game. Some earphones are not well designed for a long time, and if they are too hard or too big, they will cause damage to the inner ear canal after wearing them for a long time. Therefore, you should choose soft and comfortable headphones with the maximum amount of sensitive dust.

Then you'd better stop wearing it in the near future. Good for your ears too.

In other words, you can ** without headphones.

It's not so absolute, because the cause of your ear pain is not particularly clear, but it is said that the headphones have been worn for a long time, and they have a certain effect on the ears.

Does it have anything to do with picking out your ears?

Wearing headphones, others can hear the sound coming from the headphones, how to solve it.

Hello dear, this problem may be because the sound of the headphones leaks out, causing the people around to be able to hear it. The solution is as follows: 1

Replace the headphones: If the quality of the headphones is not good or they have been used for a long time, the sound may leak due to the lack of experience. Consider switching to a better quality headset.

2.Adjust the volume: Turn down the volume of your headphones to reduce the likelihood of sound leakage.

3.Replace the earbuds: Some earphones come with multiple ear tips of different sizes, so you can choose the right ear tips according to your ear size, which can better isolate outside sounds.

4.Use earphone covers: Some earphone cases can effectively reduce sound leakage, so consider purchasing some specialized earphone sleeves to use.

5.Adjust the way you wear them: Wearing your headphones correctly can also reduce the likelihood of sound leakage.

Try inserting the headphones deeper into your ear canal or wrapping the cable around the back of your ear to better isolate outside sounds.

Wearing headphones, others can hear the sound coming from the headphones, how to solve it.

Hello! Hello, if you wear headphones and others can hear the sound coming from the headphones, there are generally two possible reasons. The first reason is that there is a problem with the headset itself, such as loose headphone wiring, damaged headphone driver unit, etc.

The second reason is sound leakage, which is that the sound isolation of the headphones is not good, causing the sound to leak out from the outside of the headphones. For the first reason, you can try to change the headphones or repair the headphones. If it is the second proto-open cause, the following measures can be taken to solve the problem:

1.Use earbuds: Earbuds can better isolate outside noise and reduce sound leakage.

2.Adjust Qi Coarse Volume: Lowering the volume of your headphones can reduce sound leakage.

3.Replace the ear pads: Some headphones have ear pads made of different materials, and choosing ear pads with better sound isolation can reduce sound leakage.

4.Replace the earphone cable: Some earphone lines are loose or aging, and replacing the line can solve the sound leakage problem.

In short, to avoid sound leakage from headphones, you need to choose headphones with good sound isolation, adjust the volume, replace the ear cushions or headphone cables, and other measures. Hopefully, the above can help you a little

The voice of a person always unconsciously adapts to the volume of the voice heard. For example, in a noisy environment, we naturally speak loudly, and in the silence of a librarian, we naturally speak in a low voice. When you wear headphones because they are directly in the ear canal, you will naturally think that the sound is not small, and the voice will naturally become louder.

When I hear others talking, I can't feel the size of my own voice.

The reason why you will speak loudly when listening to headphones is not the same as when you will speak loudly when you are **.

When listening to headphones, the sound of the headphones covers up part of your voice, you can't hear it yourself, in fact, others can hear it, but the brain doesn't think so, it will increase the volume, so that you can hear the volume of your voice to the previous level, so that your voice is amazing. But you can still consciously lower the volume, although you can't hear what you're saying, but others can hear it. Listening to headphones for a long time is harmful to the ears, pay attention to rest your ears, and the volume is best not to exceed the maximum volume of 1 3

I will speak loudly when I hit **, mainly because of mental tension, and some writers are because they have a loud voice, and they are used to being like that.

Wearing headphones, others can hear the sound coming from the headphones, how to solve it.

Hello dear, I'm glad to serve you, put on headphones to listen to Chang Shoucha** others also hear the sound mainly in the following situations: the sound of the headphones or the sound of the ** device is too loud, and you can make it smaller. The sound insulation effect of the earphone itself is not good, so you can replace it with a headphone with sound insulation celery to make the effect better.

Headphones are headphones that do not cover the ears, there will be some external sound, you can choose large headphones, headphones that can cover the ears will be much better. Replace the headphones with noise-canceling headphones, and others won't be able to hear them. Wear headphones correctly, wear them correctly according to the signs of headphones, adjust the volume appropriately, do not use the headphone volume too much, if it is too large, some headphones can be heard by others, and it will hurt the ears.
