How bone conduction headphones work, how to use bone conduction headphones?

1. Turn on the Bluetooth headset: press and hold the power button for 5 seconds.

2. Red and blue lights flash alternately. Sound: pairing, connect to bluez 2 by aftershokz, please enter the password of "bluez 2 by aftershokz", 0000, when the pairing is successful, the sound generator vibrates:

connected, the indicator turns blue.

The vibrations of these headphones are quite noticeable.

It directly vibrates the mastoid process at the back of the human ear to drive the ossicles to make sounds.

There is no damage to the human ear.

Let's put it this way, this headset was originally intended to be used to hear others in noisy environments, as well as in very secret environments, such as **, SWAT infiltration, and whispered conversations that require a very low voice... was born ... Having said that, the so-called hearing loss is a bit unfounded, isn't it hearing loss with headphones?

Don't believe it because of choking on food...

Listening to this kind of headphones, aren't you afraid that hearing loss is irreversible? . .

(1) Health

Bone conduction is the principle of bone vibration and sound transmission, which transmits sound directly through the skull to the ear nerve inside the ear. Because the eardrum is not required, hearing is not affected.

(2) Security

Sounds around bone conduction headphones can still be heard and general conversations can be carried out, which also avoids the risk of accidents caused by not being able to hear outside sounds.

(3) Hygiene

Because bone conduction headphones do not need to be placed in the human ear, it is very helpful to maintain the hygiene inside the ear; At the same time, the bone conduction headphones have a smooth surface and are easy to clean. Traditional in-ear headphones are prone to bacterial deposits.

(4) Comfort

The bone conduction headphones are fixed on the head, and they will not fall off during exercise, which will not affect the good mood of running and listening to songs.

Disadvantages of bone conduction headphones:

(1) Sound quality

Because it is transmitted through the skin, bone and skull to the ear ossicles, the separation and reduction degree of ** is worse than that of in-ear headphones. However, everyone's feelings and preferences for ** are different, and you can only know how well the headphones sound after actually listening to them. However, in the case of sports earphones, in addition to the sound quality, it is more important whether they can fit snugly with the ears, not shift or fall off due to shaking, and not bring additional weight burden to the head and ears.

(2) Sound leakage

Although bone conduction headphones can clearly transmit sound through the skull to the inner ear, for the sake of wearing comfort, the bone conduction headphones do not adhere to the skull, so some of the energy will cause air vibration and cause sound leakage.

Classification of bone conduction headphones.

Bone conduction headphones are divided into bone conduction speaker technology headphones and bone conduction microphone technology headphones.

a) Bone conduction speaker technology headphones:

Using bone conduction technology, sound waves are transmitted directly through the bone to the auditory nerve by pressing close to the bone. Therefore, both ears can be opened without harming the eardrum. In the military and civilian fields, it is generally used to directly conduct sound on the cheekbones of the face.

b) Bone conduction microphone technology headphones:

Bone conduction technology is used to collect sound, and sound waves are transmitted through the bones to the microphone. In the civil field, bone conduction technology is generally used to reduce noise.

Due to the needs of military scenes, sometimes it is not possible to speak loudly, and the loss rate of sound conduction in the bones is much lower than that of air conduction, while bone conduction microphone technology headphones mainly use throat bone conduction. Due to the short distance, the loss is low. The soldier only needs to make a small sound to deliver exactly what he wants to say.

Origin of bone conduction headphones: The emergence of bone conduction headphones was in 1935, when Edgar Hand first began to equip patients with bone conduction headphones to help them hear what was around them, and then bone conduction was gradually incorporated into the scope of medical research until the beginning of the 21st century, when consumer electronics were known to the world.

The earlier application of bone conduction is said to have been the reason why the composer Beethoven was able to compose after he became deaf, and it is said that he tried a technique invented by Giovanni Filippo Incencia - biting a stick connected to the piano can hear ** from the jawbone.

At present, bone conduction headphones on the market are doing betterShokin and Nanka, Nanka is mainly cost-effective, while Shokin is a high-end brand route, and the gap between the two is large.

When we eat cookies, we can hear the sound of cookies shattering because the vibrations are transmitted through our teeth and skulls to our inner ears. When we eat, drink, or scratch our heads, we can hear the sound of bone conduction.

In fact, as early as the 18th century, the principle of bone conduction helped Beethoven, the great composer who was deaf in both ears, to hear the wonderful ** again. Beethoven tried it at the time by Giovanni. Filippo.

A technique invented by Inglacia, in which he bites a stick connected to a piano and can hear ** coming from the jawbone, is actually an early application of the bone conduction principle of sound.

Bone conduction technology is mainly used in military and police professional headsets, hearing aids, sports headphones and other fields.

(1) Bone conduction speaker technology headphones:

When wearing and using, the ears are open and do not block the ears, which solves the discomfort of wearing in-ear headphones.

At the same time, it also avoids a series of hygiene and health problems caused by sweating in the ears when wearing headphones for exercise. Therefore, bone conduction speaker headphones are ideal for sports use.

The opening of the ears also ensures the possibility of headphone use in dangerous situations. Open both ears and use the headphones while noticing changes in your surroundings, making it safer to use.

2) Bone conduction microphone technology headphones:

Due to the close distance at which the sound is collected, the loss is low. It is mainly used in the military field to make the other party clearly aware of the instructions expressed even if the volume of speech is very small.

With the continuous development of social economy, people's physical health will gradually have some problems, many friends will have some problems with hearing, some friends have problems with their eyes, but in fact, for friends with hearing problems, you can use bone conduction headphones to help you assist your hearing, of course, the use of bone conduction headphones is actually very good, but there are pros and cons, this needs to be comprehensively analyzed before you can make relevant choices.

First of all, let's introduce the advantages of bone conduction headphones, bone conduction headphones use the method of bone conduction original sound transmission, rather than air conduction, so the vast majority of bone conduction headphones are actually not affected by binaural or environmental sound when used, as we all know, in the process of obtaining sound, environmental factors occupy a large part, and bone conduction headphones can avoid the appearance of these factors, so as to better assist patients with hearing impairment to restore hearing to a certain extent.

Furthermore, most of the entrained positions of bone conduction headphones are the hard parts of the bones, not the soft parts of the bones, so wearing this headphones for a long time will not easily cause ear pain compared to conventional headphones, and can give a more comfortable environment for wearing. It must be worn so that it is tightly attached to the perimeter of the ear**, but if you do this, it is likely to cause hearing loss because it is not tightly attached**.

In fact, there are many good and bad things, we only need to choose the relevant headphones according to our own needs, but according to the relevant use of bone conduction, bone conduction headphones are still very good, at least to a large extent to help patients assist in hearing recovery.

Personally, I feel that the effect of this headset is not very good, there is a problem with the sound quality of this headset, and there is also a phenomenon of sound leakage, and the effect is very bad to use.

It works really well because these headphones use bone conduction, so they sound particularly clear.

The effect is still very good, and it can be seen that China's science and technology are getting stronger and stronger, so such headphones will be developed.
