Bone conduction headphones

Bone conduction is a method of sound conduction, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph, auger, and auditory center.

Compared with the classic sound conduction method that generates sound waves through the diaphragm, bone conduction eliminates many steps of sound wave transmission, and can achieve clear sound restoration in noisy environments, and sound waves will not affect others due to diffusion in the air. . Bone conduction technology is divided into bone conduction speaker technology and bone conduction microphone technology:

(1) The bone conduction speaker technology is used to send a voice, and the voice is heard when the voice is sent. Air conduction speakers convert electrical signals into sound waves (vibration signals) and transmit them to the auditory nerve. The bone conduction speaker is the sound wave (vibration signal) converted by the electrical signal directly transmitted to the auditory nerve through the bone. The transmission medium of sound waves (vibration signals) is different.

(2) Bone conduction microphone technology is used to receive a call, and the voice is collected when the call is received. Air conduction transmission is the transmission of sound waves through the air to the microphone, while bone conduction transmission is transmitted directly through the bone.

Headphones made with these bone conduction technologies are called bone conduction headphones, also known as bone conduction headphones, bone-sensing headphones, bone-conduction headphones, and bone-sensing headphones.
