BRIEF DESCRIPTION OF THE DRAWINGS FIG.

In FIG. 1, reference numeral 10 denotes an in-ear hearing aid, and a sound emitting portion of an earphone 13 is integrally fitted into a through hole 12 provided at a distal end portion of a case 11 via a coupling member 14 from the inside. An earplug 15 formed by molding a flexible synthetic resin material from the outside is integrally fitted.

The earplug 15 has a bowl shape as a whole,
A fitting hole 17 is formed in the base portion 16 from the inside, and the distal end of the fitting hole 17 communicates with a cylindrical hearing aid chamber 20 having a distal end surface closed by a top plate 19 through a communication hole 18. . An umbrella-shaped fitting part 21 formed at the tip of the case 11 is fitted into the fitting hole 17 of the earplug part 15, whereby hearing aid sound emitted from the tip face of the earphone 13 is directed toward the tip of the earphone 13. Through the acoustic damper 22 provided at a position outside of the earpiece 15, and further through the communication hole 18 of the earplug part 15 to the hearing aid sound chamber 20. A plurality of hearing aid sound emission windows 23 are formed in the peripheral wall portion of the hearing aid sound chamber 20 at predetermined intervals so as to penetrate through the thickness thereof, so that the hearing aid sound led out to the hearing aid sound chamber 20 can be heard. It is configured to be able to discharge laterally from the helical portion 15.

A flare portion 24 having a small thickness is extended on the outer peripheral edge of the rear end portion of the base portion 16 so as to protrude rearward and outward from the rear end side position of the hearing aid sound emission window 23.
Is covered with a flexible earplug 15. A flange 25 is provided on the outer peripheral edge of the distal end portion of the base portion 16 so as to laterally extend outward from the distal end position of the hearing aid sound emission window 23, and the outer peripheral edge of the flange portion 25 extends rearward from the distal end side. The flange 25 is bent rearward as shown by a two-dot chain line in FIG. 1 so that the outside of the hearing aid sound emission window 23 can be covered by the flange 25.

In addition to this, as shown in FIG.
A circular dish-shaped concave portion 26 is formed at the distal end of the base 6 so as to open in the distal direction, whereby earwax is scraped off in the direction of the base 16 from the front in the distal direction of the base 16. The earwax can be stored in the recess 26 when the earwax is turned off.

As further shown in FIG. 3, an earwax screen 27 made of, for example, an open-cell sponge is provided in the hearing aid sound chamber 20.
Is press-fitted, and thus the sound damper 22
The hearing aid sounds through the communication holes 18 and through the communication holes 18.
When the hearing aid sound is released to zero, the hearing aid sound is emitted from the hearing aid emission window 23 to the outside of the earplug part 15 and, consequently, to the ear canal through an infinite number of continuous bubbles present in the earwax screen 27. On the other hand, when earwax enters the hearing aid chamber 20 through the hearing aid emission window 23 from the outside of the earplug part 15 and thus from the ear canal side, part of the earwax enters the earwax screen 27. Although it is pushed into the myriad of open cells, most of them are kept at the hearing aid emission window 23 because they do not enter the open cells.

In the above configuration, when the in-ear hearing aid 10 is inserted into the external auditory canal 7, as shown in FIG. The flare portion 24 is pushed into the back along the ear canal 7 while softly sliding on the inner wall 8 of the ear canal.

At this time, the concave portion 26 formed at the distal end of the base portion 16 accumulates the earwax scraped into the concave portion 26 from the front of the base portion 16 and the outer peripheral edge of the flange portion 25 has the outer ear canal. By being pushed rearward from the tip side of the base 16 by the inner wall 8, the flange 25 is bent rearward so as to cover the hearing sound emission window 23, and as a result, earwax enters the hearing aid emission window 23. Can be reduced. When the in-ear hearing aid 10 is detached from the external auditory canal 7, the wearer cleans the earwax collected in the recess 26 so that the recess 26 is removed.
Can be kept clean.

Further, when earwax invades from the hearing aid sound emission window 23, the earwax is accumulated at the hearing aid sound emission window 23 by the earwax screen 27 pressed into the hearing aid sound chamber 20, and does not enter the case 11. I can do it. When the open cells of the earwax screen 27 are clogged as the use of the in-the-ear type hearing aid 10 passes, the earplug portion 1
5 is an umbrella-shaped fitting portion 21 formed at the tip of the case 11
When the earwax screen 27 is removed and cleaned or replaced, the hearing aid sound can be always heard without deterioration of the hearing aid sound.

According to the above configuration, the hearing aid sound emission window 23 is provided on the base part 16 of the earplug part 15 formed of a flexible synthetic resin material, and the hearing aid sound emission window 23 is covered. By providing the bent flange portion 25, clogging of the earwax in the hearing aid sound emission window 23 can be reduced.

Further, by providing a circular dish-shaped concave portion 26 at the tip of the base portion 16, clogging of the hearing aid sound emission window 23 with earwax can be further reduced.

Further, since the earwax screen 27 made of an open-cell sponge is press-fitted into the hearing aid sound chamber 20, the penetration into the case 11 can be reduced.

In the above-described embodiment, the case where the present invention is applied to the in-ear hearing aid 10 has been described. However, the present invention is not limited to this and can be widely applied to various hearing aids. For example, FIG. 5 shows the case where the present invention is applied to a box-shaped hearing aid. If the earplug part 30 is attached to the fitting part 31 of the earphone part 32 derived from the hearing aid body, the same effect as in the above-described embodiment can be obtained. Can be obtained. FIG. 6 shows a case where the present invention is applied to an ear-hook type hearing aid. If an earplug part 40 is attached to a fitting part 41 formed at the tip of a sound guide tube 42, the same as in the above-described embodiment. The effect of can be obtained.

In the above-described embodiment, the earplug 15 attached to the hearing aid has been described. However, the earplug is not limited to this, and a sound output section is inserted into the external auditory canal 7 and the sound output section is connected. The sound may be attached to various earphones or the like that introduce sound into the external auditory meatus 7 via the earphone.

In the above embodiment, the case where the earwax screen 27 made of an open-cell sponge is used has been described. However, the present invention is not limited to this, and a nonwoven fabric may be used instead. The same effect as in the above case can be obtained by using an earwax preventing member that allows hearing aid to pass through and prevents invasion of earwax.
