Taking a hearing aid earphone as an example, the hearing aid earphone directly plays a hearing aid role by improving the sound pressure through an air conduction mode, the transmission path of the hearing aid earphone is sound wave-auricle-external auditory canal-tympanic membrane-malleus-incus-stapes-vestibular window-external and internal lymph-spiral organ-auditory nerve-auditory center, therefore, a patient with serious problems of auricle-external auditory canal-tympanic membrane cannot play a hearing aid role, if the user is mainly focused on nerve deafness, the air conduction type earphone is difficult to pick up the vibration of the auditory bone chain, difficult to make the inner ear have a hearing function, and has little effect on severe deafness. Due to the different location and degree of the pathological changes of deafness, the periosteum and ossicular chain are difficult to generate the same frequency response with the original signal, and the sound is heard but is not clear. As with hearing aids, other earpiece-type products also face this problem.

In addition to air conduction headsets, bone conduction headsets are also common on the market, which convert sound into mechanical vibrations of different frequencies, transmitting sound waves through the human skull, bony labyrinth, inner ear lymph, helicator, auditory center. Bone conduction hearing aid earphones are on the market, and because the music is conducted to the ossicles of the ears through the skin and the bones of the skull, the separation degree and the reduction degree of the music are poorer than those of air conduction earphones.
