る。As shown in FIG. 1, the in-ear type hearing aid according to the present invention comprises an in-ear type hearing aid body 1, an earwax preventing member 2, a fixing member 3 and the like. A sound emission hole 4 is formed at the tip of the main body 1 of the hearing aid. The earwax preventing member 2 is detachably attached to the fixing member 3 fitted and fixed to the sound emitting hole 4. Reference numeral 5 is a sound guide tube for guiding the hearing aid sound emitted from the earphone (not shown) built in the main body 1 of the hearing aid to the sound emitting hole 4.

７ａが形成されている。The earwax preventing member 2 is integrally formed of a soft elastic member (for example, silicone rubber) such as a polymer material or rubber. The earwax preventing member 2 includes a base portion 6 having a substantially truncated cone shape, a rod-shaped shaft portion 7, and a disc-shaped lid portion 8. The base 6 is formed with a communication hole 6a that connects the sound guide tube 5 of the ear-hearing aid 1 and the outside. Further, near the boundary between the base portion 6 and the shaft portion 7, a small diameter portion 7a thinner than other shaft portions is formed.

段部３ｃを有している。The fixing member 3 is made of a hard polymer material and is formed in a substantially cylindrical shape, and has a large diameter hole 3a, a small diameter hole 3b and a step portion 3c on the inner circumference.

Next, the fixing member 3 is engaged so that the base 6 of the earwax preventing member 2 engages with the step 3c of the fixing member 3.
The base 6 is press-fitted into the large diameter hole 3a. At the time of press fitting, since the earwax preventing member 2 is formed of an elastic member, the base 6
Passes through while deforming the small diameter hole 3b of the fixing member 3.

取り外すことができる。Once the earwax-preventing member 2 is attached to the earplug-type hearing aid body 1, since the outer diameter of the base 6 of the earwax-preventing member 2 is larger than the inner diameter of the small-diameter hole 3b, the earwax-preventing member 2 is inserted into the ear. The hearing aid body 1 does not easily come off. But,
The earwax-preventing member 2 can be removed from the in-ear type hearing aid body 1 by applying a large force such that the base portion 6 is deformed and pulling it toward the lid portion 8 side.

む。The operation of the ear-hearing aid according to the present invention will be described below. When ear wear is present in the ear canal of the wearer of the ear-hearing aid, the state when the ear-hearing aid is attached to the ear canal of the wearer is as shown in FIG. That is, when the peripheral portion of the lid portion 8 hits the earwax 10 attached to the wall of the external auditory meatus 9, the shaft portion 7 bends in the arrow A direction with the small diameter portion 7a as a bending point.

Ｂで示す経路で外耳道９の奥部に達する。Therefore, the gap G formed between the lid member 8 and the ear-hearing aid body 1 is narrowed. This prevents the earwax 10 from entering the interior of the hearing aid body 1 through the gap G. At this time, the gap G on the opposite side formed by the lid member 8 and the ear-plug type hearing aid main body 1 expands, so that the hearing aid reaches the inner part of the external auditory meatus 9 along the path indicated by the arrow B.

ほとんど感じさせない。On the other hand, if the wearer's ear canal does not have earwax 10, the lid 2 may come into direct contact with the wall of the ear canal 9 during insertion. However, since the lid portion 2 is formed of a soft elastic member such as a polymer material or rubber, even if the lid portion 2 comes into contact with the wall of the ear canal 9, the wearer hardly feels pain.

補聴器を装用できる。Further, even if the earwax preventing member 2 is soiled or damaged due to long-term use, the earwax preventing member 2
Is detachably attached to the body 1 of the hearing aid, the earwax hearing aid can always be comfortably worn by removing the earwax prevention member 2 and washing or replacing it with a new earwax prevention member 2.

ができる。In the above-described embodiment, the small diameter portion 7a is provided on the shaft portion 7 of the earwax preventing member 2, and the small diameter portion 7a is provided.
The shaft portion 7 is designed to bend with a as a bending point. However, even if the small diameter portion 7a is not provided and the diameter of the shaft portion 7 is set so that the entire shaft portion 7 bends, the same operational effect can be obtained.

Base made of elastic material, rod-shaped shaft and disk-shaped lid
The earwax preventive member consists of
The peripheral part of the lid corresponds to the earwax attached to the wall of the ear canal
With this, since the shaft portion is bent and the gap is narrowed, it is possible to effectively prevent the earwax from entering the inside of the hearing aid device through the gap .
