Background
The hearing aid is a small-sized loudspeaker, which enlarges the originally inaudible sound and then utilizes the residual hearing of the hearing-impaired person to enable the sound to be transmitted to the auditory center of the brain so as to feel the sound. Bringing great convenience for hearing-impaired people.
With the development of science and technology, current hearing aids are mainly divided into general (air conduction mode) hearing aids and bone conduction hearing aids; in general, a hearing aid using an air conduction method collects sound through 1 or more microphones, and amplifies and compresses the sound in different frequency bands by using a chip algorithm in the hearing aid. Finally transmitting the processed sound to the inner ear through an earphone placed in the ear; bone conduction hearing aids then transmit the sound directly to the temporal bone through a vibrator, ultimately transmitting the sound vibrations to the cochlea and hair cells.
However, the common (air conduction mode) hearing aid can well prevent external sound from naturally transmitting into the ear cavity through the external auditory canal of a user and interfering with sound transmitted by the hearing aid, but has the disadvantages that air pressure is also isolated while sound inside and outside the ear cavity is isolated, so that discomfort such as distending pain and the like is generated in the ear cavity due to the difference between air pressure inside and outside the ear cavity when the user uses the hearing aid for a long time, the originally damaged eardrum is further deteriorated and aggravated, and the hearing is reduced; compared with the air conduction hearing aid, the bone conduction hearing aid can improve discomfort caused by air pressure difference inside and outside the ear cavity, and is better in comfort.

The bone acoustic conduction frequency range can completely reach 50Hz-20 kHz; compared with the frequency response range of the medium-high-end air conduction hearing aid in the general market, the frequency response range of the medium-high-end air conduction hearing aid is only about 300Hz to about 10kHz, and the frequency response range of the bone conduction hearing aid in the market is about 100-3 kHz; the frequency range of the application can be greatly expanded, so that the bone sound conduction hearing aid of the application is not limited by the sound production frequency and influences the sound production effect, and better hearing aid experience is provided for a user.
The beneficial effect of this application still includes: the in-ear bone sound conduction audiphone has combined the advantage that the air conduction audiphone alleviates noise interference and the advantage of the comfort that the bone conduction audiphone reinforcing was worn, and its bone sound conduction speaker can pass through drive arrangement vibration transmission piece and shell fragment and make the neural sympathetic response of cochlea strengthen, possess fine low frequency dive to the well high frequency sound wave of vibrating diaphragm radiation itself makes the more concentrated of sound propagation through the play sound hole of cavity, and the directive property is stronger, improves sound propagation efficiency. Wherein vibrating diaphragm radiation sound can be through the air from the external ear, the auditory nerve transmission of middle ear to the inner ear, the drive arrangement of bone sound conduction speaker, shell fragment etc. through the skull with sound not passing through external ear and middle ear, directly transmit the auditory nerve of inner ear to whole working frequency is relatively broader, tone quality equilibrium degree is good, there is big developments, there is fine stereovision, the bass is full powerful, there is fine bass dive, the middle pitch is clear simultaneously, the high pitch is fine and smooth.
The in-ear bone sound conduction audiphone can lead to the vibrating diaphragm of bone sound conduction speaker and pass through the air with sound from the external ear, the sound nerve transmission of hearing of well ear to the inner ear, the drive arrangement and the shell fragment of bone sound conduction speaker can be again through the skull with sound not passing through external ear and well ear, through the sound nerve of hearing that soft cap 7 and preceding cavity 4 directly transmitted the inner ear to strengthen bass and low frequency dive greatly. And the ear-in bone sound conduction audiphone is wider because of operating frequency, need not high-power promotion volume make eardrum further impaired, and the different operating frequency of accessible bone sound conduction links up again and does not injure eardrum and broader sense of hearing, can alleviate the uncomfortable degree of ear simultaneously, keeps apart the sound inside and outside the duct to a certain extent to reduce the interference of external noise to sound.
