What Is a Bone Conduction Headset?

Oct. 15, 2020

There are many types of earphones, head-mounted, and in-ear. According to the sounding unit, it can be divided into moving coil type, moving iron type, and coil iron mixed type.

However, no matter how they are divided, they transmit sound into the ear canal through air vibration, allowing you to hear all kinds of sounds. There is a kind of earphone that does not need to be plugged into the ear at all and can be listened to music by gently sticking to the temple. This kind of earphone is called a bone conduction headset. You may have heard of it, but you may not understand its working principle and advantages and disadvantages.

Bone conduction earphones were firstborn in the 1990s. At that time, bone conduction earphones had high power consumption, large volume, and sound quality. That might be a good word to him because they actually didn't have any sound quality.

However, these characteristics are exactly what the military and police fields need (because of its special wearing method, it does not need to be in the ear, you can hear the outside world). So this black technology has been used in military and police communications.

In recent years, there have been great breakthroughs in the core technology of bone conduction headphones. The frequency response range can reach 50 to 20000HZ, which is basically the same as our usual headphones for listening to music, and the size has been reduced to the size of ordinary Bluetooth headphones. In other words, we can also use bone conduction headphones to listen to music.

What is bone conduction?

The reason why we can hear outside sounds is basically the credit of our ears. Sound is transmitted through the air, and when it enters the ears, it vibrates our eardrums, and then passes through a series of complex mechanical signals to the inner ear to be converted into electrical signals, and finally transmitted Given to our brain, we also "hear" the sound.

What are bone conduction headphones?

Ordinary earphones emit sound through the vibration of the speaker, and then travel through the air to enter our ears, vibrating our eardrums; and bone conduction earphones actually have a vibration system, and are similar in structure to ordinary speakers, but are different. The reason is that its "diaphragm" is a piece of metal and rubber. Its structure can transmit vibration to the skull. Of course, ordinary headphones can also transmit to the skull, but the efficiency is much worse than that of bone conduction headphones.
