Background

Bone conduction is a sound conduction mode, namely, sound is converted into mechanical vibration with different frequencies, and sound waves are transmitted through the skull, the bone labyrinth, the lymph fluid transmission of the inner ear, the spiral organ, the auditory nerve and the auditory center of a human body. Compared with a classical sound conduction mode of generating sound waves through a vibrating diaphragm, the bone conduction mode omits a plurality of sound wave transmission steps, can realize clear sound restoration in a noisy environment, and does not influence other people due to the fact that the sound waves are diffused in the air. The bone conduction technology is divided into a bone conduction speaker technology and a bone conduction microphone technology: (1) the bone conduction speaker technology is used for receiving a telephone, namely listening to sound when receiving the telephone, the air conduction speaker converts an electric signal into a sound wave (vibration signal) and transmits the sound wave (vibration signal) to an auditory nerve, and the bone conduction speaker directly transmits the sound wave (vibration signal) converted from the electric signal to the auditory nerve through a bone.
