Bone conduction headhone is a popular digital product nowadays, which is very popular among young people and sports experts. Compared with traditional earphone, people’s understanding of bone conduction headphone is still relatively fuzzy. Let’s have a detailed understanding of it below.
Before we look at bone-conducting headphones, let’s look at sound transmission.
Propagation of sound
We know that the sound produced by the vibration of objects, can produce a sound object is called a sound source. The most familiar medium for sound transmission is air. In addition to air, liquid and solid can also transmit sound.
And our ears are the instruments that sense sound, and we can tell where the sound is by our ears, like in an action movie where we’re blindfolded, and we can tell when an opponent is punching us by our ears.
How the ear acquires sound starts with the structure of the ear:
The human ear hears sounds through the external auditory canal — tympanic membrane — small auditory bone — cochlea — auditory nerve, and finally acquired by the brain. This vibration through the external auditory canal and periosteum is to take the air as the medium, if not through the external auditory canal, but directly through the small bone to feel the vibration of sound.
Same can send sound to cerebrum, it is bone conduction, of course sound also can pass jaw bone to hear small bone to be transmitted again next to hearing nerve, can cause hearing likewise.
The principle of bone conduction headphone
Studied physical friends should know that in the normal environment conditions, there are two kinds of sound transmission, it is spread through the air, the other is communicated through certain media, we use the traditional headphones is mainly the transmission of sound through the air, and the bone conduction headphone is with the aid of certain media skull (the head) for the transmission of voice, in the end, in the form of sound waves to sound conduction to the auditory nerve directly, and no longer need through the air to the eardrum, first to reach our auditory nerve.
The appearance of bone conduction headphones
Bone conduction headphones first appeared in 1935, when Edgar Hand first began giving patients bone conduction headphones to help them hear what was going on around them, and bone conduction was gradually incorporated into medical research until it became widely known as consumer electronics in the early 2000s.
An earlier bone-conduction application is said to have involved composer Beethoven, who was deaf, trying a technique invented by Giovanni Phillippo Ingracia to listen to music from his jawbone while biting a stick connected to a piano.
Now, bone-conduction headphones are mainly used as sports headphones, such as running, cycling, and mountain climbing, providing people with an alternative to listening to music while exercising.
Bone conduction headphone for wearing
Due to the characteristics of bone conduction requiring contact and transmission, bone conduction earphones are worn in a different way from ordinary earphones. There is no need to cover the ear canal, and the earphones can be used simply by sticking them near the temple. This way of wearing is more comfortable than the ordinary ear, suitable for a long time, there is no risk of causing inflammation of the ear.
Bone conduction earphone structure
The earphone is similar to the earphone, which can be hung on the ear when used. The middle connection part has great flexibility, which can ensure the two earphones fit together in the middle. So even if you exercise, you won’t fall off because of looseness.
The earphones are flat round, with holes cut in the side to facilitate air circulation when speaking. The outer surface of the earphone is also printed with a similar vibration pattern, indicating that it is a vibration-induced earphone.
The connection between earphone and earphone is designed as a whole. The whole is wrapped with plastic, which is very elastic and can play a shock-absorbing role in preventing collision.
The part of the headset that is in contact with the skin is not a complete plane. There are some small holes on the sides, and these holes can also be pronounced.
During actual wearing, the ear-hanging part can fit the ear well and the earphone can be fixed.
Pros of Bone conduction headphone
- Listen with open ears to make it safer
Bone conduction principle decides that Bone conduction movement headphones don’t transmit sound through the ear canal, therefore there’s absolutely no need to pay the ear or obstruct the ear canal to attain the objective of hearing sound just like conventional headset. Thus “open ear hearing” has come to be one of the most praised benefits of bone conduction earphones.
Moreover, when sporting bone conduction Earphones, external noises may also be observed at precisely the exact same time, in order to prevent the condition of “ear blindness”. Notably in outside sports, it can’t just listen to music, but also know the surroundings, in order to prevent the incidence of harmful items and significantly enhance the security.
- Free your ears for relaxation and Wellness
Lots of you have complained about In-ear headset. Wear for quite a while will feel uneasy ears, and also feel hearing is going to be decreased. Bone conduction earphone solves this issue nicely, since bone conduction earphone doesn’t have to place the earplug into the ear, so it may continue to keep the internal ear canal clean and sterile, and prevent the incidence of ear discomfort.
Cons of bone conduction headphone
- The audio quality Isn’t good enough, Along with the noise leakage happening is severe.
Experienced from the webmaster are involved, the audio quality cannot be compared with that of specialist Bluetooth earphones or wired earphones. The bass and treble aren’t obvious, and there’s also a widespread occurrence of noise leakage.
- Insufficient battery lifetime and Inconvenient to take
Generally lighter compared to Bluetooth earphone, it ought to consume a good deal of Than that of the atmosphere. To bring a battery situation. Together with the battery situation, the earphone Isn’t very Convenient to transport.
What is the best brand of bone conduction headphone?
Here I recommend a bone conduction headset, which is more cost-effective than the same price bone conduction headphones.
