The in-ear air conduction earphone conducts sound waves emitted by the loudspeaker to the eardrum of a human body through air conduction, the eardrum of the human body has an upper limit of sound collection volume, the eardrum can be damaged after the sound volume conducted to the eardrum of the human body exceeds the upper limit of the sound collection volume (the amplitude of the sound waves), and at present, all hearing aids amplify the sound through the hearing aid, so that weak hearing can hear the sound.
Hearing aids are medical supplies that require a doctor's instruction and that require the doctor to check regularly (average 12 months/time with relatively steady hearing) and adjust the volume of the hearing aid according to the hearing situation of the user. However, since the sound volume of the hearing aid cannot exceed the upper limit of the eardrum of the human body, and if the sound volume of the hearing aid is too high, the eardrum of the user is damaged, and the upper limit of the eardrum of the weak hearing people who have certain degradation, damage, lesions or the like of the eardrum is lower, the current hearing aid cannot solve the problem when the sound volume of the hearing aid is close to the upper limit of the user and the user cannot hear the external sound.
The bone conduction hearing aid directly conducts vibration waves through bone tissues such as skull bones of a human body in a contact conduction mode, the bone conduction vibration waves bypass the tissues such as eardrum and cochlea and reach the cochlea of the human body, and the upper limit of the vibration waves of the bone conduction hearing aid which can be accepted by the human body on the premise of keeping comfort level is lower than that of an in-ear air conduction earphone. In addition, bone conduction hearing aids have problems such as leakage and high distortion, and are not suitable for users with bone tissue such as skull bone injury and lesions.
Therefore, there is no hearing aid earphone suitable for people with relatively serious weak hearing, and there is no hearing aid earphone suitable for tissues such as eardrum and bone tissues such as skull with certain degree of degeneration, injury or lesions.

In an alternative embodiment, the hearing-aid earphone is provided with a host, the battery is respectively arranged in the inner cavities of the host and the left earphone and the right earphone, and the left earphone and the right earphone are respectively connected with the host through Bluetooth in a wireless mode.
Each earphone includes a bone conduction housing and a pen air conduction housing; the inner cavity of the bone conduction shell is provided with a bone conduction hearing aid device 1, and the inner surface of the bone conduction shell is provided with a bone conduction surface which is used for being abutted against the skin of a human body and conducting vibration waves to the skull; the inner cavity of the air conduction shell is provided with a loudspeaker, and the outer end part of the air conduction shell is provided with an in-ear earplug; the bone conduction shell and the air conduction shell are integrally formed or fixed into a whole.
Conventional hearing aids operate by amplifying sound with a three-part system: the microphone receives sound and converts the sound into a digital signal, the strength of the digital signal is enhanced through the digital amplifying circuit, the digital signal is then transmitted to the earplug loudspeaker, the earplug loudspeaker is used for transmitting the amplified sound into the auditory canal, and the air conduction sound wave propagation path 4 is as follows: auditory canal → eardrum → middle ear → inner ear → cochlea.
The bone conduction earphone is not positioned in the ear, but positioned on the jawbone, the working principle of the bone conduction earphone is that sound vibration passes through chin and skull bone, bypasses other structures such as ears such as eardrum and the like and is directly transmitted to the cochlea, the bone conduction sound is heard from the inside of the ear instead of from the outside, the working principle is that a vibrator on a sound generating unit is utilized to convert sound signals into mechanical vibration, bone resonance is caused, and the sound is directly transmitted to the cochlea of the inner ear through the resonance of bone tissue, so that the bone conduction listening effect is achieved. The bone conduction acoustic wave propagation path 3 is: bone tissue such as skull, cochlea.
According to hong Kong environmental protection agency's statement, maintaining noise exposure below a maximum of 70db helps prevent life-long hearing loss. Sounds of 70db and below are generally considered safe, while any sound of 85 db and above is more likely to impair hearing over time, with a much greater risk of hearing loss for persons exposed to noise levels of 85 db or above over time, and a high probability of permanent damage.
For persons with moderate hearing loss and severe hearing loss (hearing aid users), air-vibrating hearing aids may need to be tuned to above 70db and above. However, if the sound is not amplified to 70db or more, the hearing aid user is largely unaware of the loudness of the sound, but prolonged exposure to such levels of 70db or more eventually damages the eardrum of the hearing aid user and causes deafness, i.e. permanent damage.
On the other hand, if a bone conduction hearing aid is used, where the bone conduction hearing aid is tuned to a higher power to achieve the output bone conduction sound output to a moderate hearing loss and the loudness of the sound perceived by severe hearing loss, there is a risk of cochlear hearing loss due to noise.
In order to solve the problem, we invented a hearing aid combining bone conduction and air vibration, which combines bone conduction vibration wave with sound wave intensity lower than 70db and air vibration with sound wave intensity lower than 70db by using constructive interference, because the intensity of both sound waves is lower than 70db, the vibration wave emitted by any bone conduction hearing aid device 1 is lower than the upper limit value which can be born by the cochlea and is comfortable, the sound wave emitted by any in-ear speaker sounding device 2 is lower than the upper limit value which can be born by the cochlea and is comfortable, and the permanent damage to the eardrum and the cochlea of the human body is avoided, because the phases of the two sound waves are the same when reaching the cochlea, and when the two sound waves are combined together, the receiving effect of the cochlea is equivalent to the superposition effect of the two sound waves.
When two sound waves of the same sound format from two different sources arrive at the inner ear simultaneously, they will interfere with each other, and if the two sound waves are in phase, the peaks (or troughs) are the same, they will produce constructive interference, resulting in an increase in amplitude and loudness, which is known as constructive interference.
For example, for hearing aid users who require more than 85 db in their in-ear sounds to perceive the loudness of the sounds, using either a conventional single in-ear horn sounding earpiece or a single bone conduction hearing aid earpiece, permanent damage to varying degrees is unavoidable over prolonged periods of use. The invention processes and distributes audio signals to form constructive interference, for example, for one earphone, the in-ear loudspeaker sounding device 2 of the earphone emits a first sound wave of 45 dB and the bone conduction hearing aid device 1 of the earphone emits a second sound wave of 45 dB, the first sound wave and the second sound wave are conducted to the cochlea and then are overlapped, the sound wave received by the cochlea of a single ear corresponds to more than 85 dB (the theory can reach 90 dB), the hearing aid user can easily perceive the sound, the cochlea of the double ears jointly receives the sound wave with the same phase, the hearing aid user has better perception effect on the loudness, direction and distance of the sound, but simultaneously, the eardrum of the single ear of the hearing aid user only bears sound of 45 dB, bone tissues such as skull bone tissues of the single ear side bear sound wave vibration of 45 dB, the eardrum of the hearing aid user, the skull bone tissues such as skull feel very relaxed, and the long-term wearing has extremely comfortable feeling, and the permanent damage caused by the sound wave with single conduction can be effectively avoided.
The severity of hearing impairment is described in terms of the extent of hearing loss, including: mild, moderate, severe and extremely severe.
A hearing threshold of 25dB HL or higher is generally considered normal hearing for adults.
A hearing threshold of 26-40dB HL is generally considered to be mild hearing loss,
the hearing threshold of 41-55dB HL is generally considered to be moderate hearing loss,
the hearing threshold of 56-70dB HL is generally considered to be moderate to severe hearing loss
A hearing threshold of 71-90dB HL is generally considered to be severe hearing loss,
a hearing threshold of >90dB HL is generally considered as profound hearing loss (extremely severe hearing loss).
For example, the invention sets and distributes audio signals through the control circuit, when the in-ear loudspeaker sounding device 2 of one earphone sends out a first sound wave which is 50 db comfortable for a user, the bone conduction hearing aid device 1 of the earphone sends out a second sound wave which is 50 db comfortable for the user, the sound wave received by the cochlea of the single ear of the user is equivalent to more than 95 db (the theory can reach 100 db), the problem that the loudness of sound can not be well perceived after the hearing aid is worn by the crowd with extremely severe hearing loss is easily solved, and the invention is comfortable for long-term wearing and avoids permanent damage to bone tissues such as eardrum, cochlea or skull.
For users with more than moderate hearing loss, the invention leads the volume of sound generated by each single bone conduction hearing aid device 1 or the in-ear speaker pronunciation device 2 to be smaller than the perceived loudness thereof through the arrangement of the control circuit, namely, the user can not obviously (clearly) sense or even can not sense (can not hear) any one of the single bone conduction hearing aid devices 1 or the in-ear speaker pronunciation device 2, but finally, vibration waves acting on cochlea and ossicular nerve can be superimposed to obtain the conduction effect of the total volume close to 2 times of volume, the user can clearly sense the conducted sound, the patient with severe ossicular nerve degeneration can clearly hear the external sound, the bone tissue degeneration or further injury of the patient with the hearing aid for a long time is avoided, the membrane is avoided from being damaged by the overlarge volume, and the bone tissue is also prevented from being damaged by the overlarge vibration waves.
In addition, since the frequency of the sound wave of the bone conduction hearing aid device 1 or the frequency of the sound wave generated by the in-ear speaker sound generating device 2 is different, the frequency difference is controlled by the control unit and the audio output control unit, bone conduction and air conduction are in the ear together, and besides the sound volume is increased, the music curative effect called Binalual sound is also achieved.
Binaural frames refer to audio played with a frequency difference using headphones, such as a left ear play frequency of 200hz and a right ear play frequency of 240hz, resulting in a Gamma wave frequency difference of 40 hz.
At present, a plurality of researches show that the Binalual Beats can improve working memory and concentration, and the basic principle is that the left earphone and the right earphone play audio with frequency difference at the same time to induce the brain to generate more brain waves with the same frequency difference.
