1 to 6, an ear-type hearing aid to be inserted into an external ear canal of a left ear according to the present invention includes a hearing aid having a shell (a hearing aid external body) Each having one circular hole 22, 24, and the holes 22, 24 are connected to each other by a flexible plastic pipe penetrating the inside.

In the presence of hearing loss, the most common problem when wearing a hearing aid is the occlu- sion effect, in which the sound of the self or other person is heard and heard.

The occlusion phenomenon is mainly heard by the hearing aid or by someone else's voice, sounds too soft, and is expressed by air pressure or tightness.

The closure phenomenon refers to the external appearance of the ear canal or the ear canal that closes the ear canal, causing a feeling of closure or pressure, and a sound due to the amplification of the low frequency.

The sound of the vocal cords or the sound of chewing sounds (chewing food) around the temporal mandible, and this vibration is transmitted to the cartilage around the ear canal. When a person with hearing loss wears a hearing aid, the hearing aid is manufactured to fit the cartilage to prevent sound from being echoed. This causes the vibration of the cartilage to be directed toward the eardrum, resulting in closure.

The closure phenomenon is mainly caused by the sound pressure in the low frequency band due to the nature of the physical structure and the painting sound, and may also be caused by the difference in pressure between the middle ear and the external ear canal.

In this case, the outer ear of the ear where the vibration occurs, the shell part of the hearing aid, and a loose part are formed, and the hearing aid's shell, which is connected to the specific cartilage part where vibration occurs, The pipes 30 and 34 having an opening corresponding to the holes 22 and 24 are connected at the inner side of the shell of the hearing aid to open the holes 22 and 24 having the diameter of 1 to 1.5 mm according to the size, The closure phenomenon generated by the amplification of the cartilage part of the ear canal by the hearing aid's shell is absorbed through the holes 22 and 24 pierced from both sides of the shell, Resolve.

However, when the hearing aid shell material (usually plastic material) is hard and worn on the ear canal, there is pain in the area where the ear canal fits and the feeling of tightness is severe The hearing aid's shell and ear canal parts are made to some extent for the hearing aid wearer.

The outer auditory canal of the ear consists of a curved portion (tibia), not a straight line. When the hearing aid is worn on this part, pressure and pain are generated. A gap is formed between the outer ear and the hearing aid shell, (Food chewing sound) is amplified.

This is transmitted to the hearing aid through the surface of the hearing aid which is in contact with the shell and the external ear canal, resulting in amplified sound.

1, when a hearing aid with an ear canal is inserted, a portion of the shell portion of the hearing aid contacting the curved surface of the ear canal is contacted with the shell of the hearing aid so that the chewing sound is amplified. Circular holes 22 and 24 each having a diameter of 1 to 2 mm are formed so that the area in which the shell portion of the hearing aid and the outer ear canal portion are directly in contact with each other is reduced by the area of the circular holes 22 and 24.

In the configuration of the present invention as described above, a closure phenomenon occurring when the shell of the hearing aid comes in contact with the ear canal, that is, the problem that the sound is amplified and transmitted to the hearing aid, Holes 22 and 24 respectively formed at upper and lower portions thereof are connected to each other by a first straight pipe 30 penetrating the inside thereof to relieve the feeling of pressure and pain felt inside the user's ear and to prevent the user's voice and chewing food (Dither) can be prevented from being distorted and amplified.

The shell of the ear-type hearing aid used in the present invention is a hollow structure.

The hearing aid according to the present invention has a curved shape that is close to the insertion portion 40 inserted into the ear, and the curved portion is brought into close contact with the ear canal of the user's ear. As a result, The holes 22 and 24 are drilled vertically in this portion. In the present invention, the diameters of the holes 22 and 24 are about 1 to 2 mm, but they may vary depending on the size of the shell of the hearing aid.

In FIG. 3, the first and second linear pipes 30 are formed so as to penetrate the inside of the hearing aid, so that the holes 22 and 24 formed at the top and bottom of the hearing aid can pass through each other,

4, an open hole 32 having a diameter of 0.5 mm is formed on the upper surface of the first straight pipe 30 installed at the upper and lower parts connected to the valley in the inner ear of the hearing aid inserted into the ear canal of the left ear according to the present invention A second linear pipe (42) penetrating the inside of the hearing aid body (hearing aid body) according to the present invention having a receiver bar is separately provided, and the end of the second linear pipe (42) The hearing aid according to the present invention is connected to the plate portion having the microphone, that is, the hole 36 formed in the lower portion of the hearing aid microphone operation switch 12, so that unnecessary sound generated inside the hearing aid is discharged to the outside.

Even if the hearing aid according to the present invention does not include the hole 32 formed below the hearing aid microphone operating switch 12 and the straight pipe 42 connected to the hole 32, even if the user wears the hearing aid according to the present invention There is a sufficient effect in offsetting the amplification of the dither and external sound.

5, the use of a T-shaped pipe 34 formed so as to penetrate the inside allows the holes 22 and 24 formed at the top and bottom of the hearing aid and the hole 26 formed at the outside of the hearing aid provided outside the microphone, .

According to the embodiment shown in Fig. 5, the sound and the hearing aid shell, which are blocked through the upper and lower holes 22 and 24 through the hole 26 formed on the outer side of the hearing aid provided with the microphone, The air pressure can be discharged.

However, even if the hearing aid has holes in the hearing aid, the holes 22 and 24 are only vertically connected to the valleys connected to the inside of the hearing aid, A sufficient effect of canceling the amplification of the amplified product is obtained.

5, when the hearing aid according to the present invention is worn by inserting the hearing aid into the ear, the holes 22 and 24 formed in the upper and lower portions near the insertion portion 40 of the hearing aid are inserted into the skin of the ear canal of the user's hearing aid user As shown in FIG.
