Bone conduction concept and the advantages of bone conduction headphones
- Bone conduction concept: bone conduction is a voice transmission, that is, the sound into a different frequency of mechanical vibration through the human skull, bone lost, inner ear lymph fluid transmission, Bone conduction eliminates the need for a lot of steps in acoustic transmission compared to classical acoustic transduction that produces sound waves through a diaphragm, enabling clear sound reduction in noisy environments, and sound waves that do not affect others as they diffuse in the air.
- Bone conduction headphones advantages: safety, health,comfort, noise reduction is the characteristics of bone conduction.
Security: Bone conduction earphone is binaural open, when you use headphones for running, mountain climbing, cycling and other outdoor sports, can be a good perception of the surrounding sound, from improving the security.
Health: General ear headphones to wear in the ear canal, will form a moist, closed ear canal environment, easy to breed bacteria, causing otopathy. Bone conduction headset sound transmission process does not go through the ear canal and tympanic membrane, the normal wear when the ear is fully open state,can effectively ensure the health of the ear canal.
Comfortable: bone conduction headphones and traditional headphones different, do not block or cover the ears, so a long time to wear will not produce discomfort .
Noise reduction: in a noisy environment to achieve a clear hearing of the sound, the smaller the interference by the environment.
