Headphones have become a must-have electronic product for each of us. Whether it is on the street, on a bus, or even in a shopping mall or a coffee shop, there are always many people with a pair of headphones in their ears, immersed in their own in the world. Nowadays, there are more and more styles of earphones, but are the bone conduction earphones that appeared a few years ago good? How is it different from our usual headphones?
The sound transmission principle of bone conduction earphones is to transmit sound directly to the inner ear and cochlear nerve through the vibration of the skull. This mode of transmission does not pass through the ear canal and eardrum. Therefore, compared to traditional in-ear headphones, bone conduction headphones are safer, healthier, more hygienic, and can really relax the ears. Therefore, bone conduction plays a role in protecting the health of the human ear.
Earphones with bone conduction technology do not transmit sound through the air but through bone vibrations to transmit sound. Even if you cover your ears and press the earphones tightly to the bones above your ears, you can still hear the sound. The reason why the composer Beethoven was able to compose music after he was deaf is said to have tried a technique invented by Giovanni Filippo Ingrasia - biting a stick connected to the piano Hearing music from the jawbone should be regarded as an early application of the principle of bone conduction.
1. Free your ears
The biggest advantage of bone conduction headphones is to liberate our ears. Friends who often use headphones know that whether it is in-ear, semi-in-ear or headphone, it will cause pressure on the ear, and there will be obvious discomfort after wearing it for a long time.
2. Safer to use
Traditional earphones need to block the ears, so the sound of the outside world is easily blocked. In this way, when we are exercising or driving, some situations cannot be heard in time, and it is difficult to respond to danger in time.
Bone conduction earphones are not limited by the ears, so they can receive all sounds from the outside world and respond in a timely manner. They are not only safe, but also have no barriers to communicating with people.
3. More hygienic
Traditional earphones are plugged into the ears, which can easily bring dirt into the ear canal, and sweat is mixed in during exercise, especially, bacteria can easily breed over time.
The design of bone conduction earphones does not go into the ear, which can completely avoid these problems.
In 1935, Edgar Hand first began to equip patients with bone conduction earphones to help them hear things around them. Then bone conduction was gradually included in the scope of medical research, and it was not until the beginning of the 21st century that electronic consumer products became known to the world. .
In recent years, some companies have applied bone conduction earphones to Bluetooth earphones, which can avoid ear swelling and discomfort caused by traditional earphones wearing earphones for a long time.
