Description

Composite loudspeaker and sounding device technical field

Background technique

Using bone conduction technology to receive words, it is close to the bone, and the sound wave is directly transmitted to the auditory nerve through the bone. Therefore, both ears can be opened without damaging the eardrum. Bone conduction generally uses the cheekbones of the face to conduct sound directly.

There are two ways of bone conduction: moving type and squeezing type. The two synergistically stimulate the screw to cause hearing. The specific conduction path is: "sound wave - skull - bone labyrinth - inner ear lymph - Spiralizer - auditory nerve - The auditory center of the cerebral cortex". Usually people do not need to use their skulls to feel the sound, but when the lesions of the outer ear and middle ear block the transmission of sound waves, bone conduction can be used to make up for hearing. Such as bone conduction hearing aids, Bone conduction headphones, etc., use bone conduction to experience sound.
