Description

本発明は、耳せんの形状に特徴がある耳かけ形補聴器に関する。 The present invention relates to a behind-the-ear hearing aid characterized by the shape of an earplug.

従来の耳かけ形補聴器の耳せんは、略マッシュルーム形状をしている（例えば、特許文献１参照）。 The earplug of the conventional ear-hook type hearing aid has a substantially mushroom shape (see, for example, Patent Document 1).

登録実用新案第３０１３２６２号公報Registered Utility Model No. 3013262

しかし、特許文献１に記載のように、耳せんが略マッシュルーム形状をしていると、外耳道から耳せんを外す際に、マッシュルーム形状の傘部が外耳道に引っ掛かり、不快に感じることがあった。また、傘部が外耳道の形状に合うように曲がって変形すると、しわが生じ安定した装用感が得られないことがある。更に、しわの隙間から音が漏れ、ハウリングする場合がある。 However, as described in Patent Document 1, when the earplug has a substantially mushroom shape, when the earplug is removed from the external auditory canal, the mushroom-shaped umbrella may be caught on the ear canal and feel uncomfortable. Further, when the umbrella portion is bent and deformed so as to match the shape of the ear canal, wrinkles may occur and a stable wearing feeling may not be obtained. Furthermore, sound may leak from the wrinkle gap and howling may occur.

本発明は、従来の技術が有するこのような問題点に鑑みてなされたものであり、その目的とするところは、着脱が円滑で装着感に優れ、ハウリングし難い耳かけ形補聴器を提供しようとするものである。 The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to provide an ear-shaped hearing aid that is easy to attach and detach, is excellent in a feeling of wearing, and is difficult to perform howling. To do.

上記課題を解決すべく請求項１に係る発明は、耳せんの形状を、略球形状または略楕円球形状とした。 In order to solve the above-mentioned problems, the invention according to claim 1 has the shape of the earplugs of a substantially spherical shape or a substantially elliptical sphere shape.

請求項２に係る発明は、請求項１記載の耳かけ形補聴器において、前記耳せんを、弾性体で形成した。 The invention according to claim 2 is the ear-hook type hearing aid according to claim 1, wherein the earplug is formed of an elastic body.

請求項１に係る発明によれば、略球形状の耳せんまたは略楕円球形状の耳せんには傘部がないので、外耳道に引っ掛かることがなく、着脱が円滑である。また、略球形状の耳せんでは、外耳道への挿入角度の自由度が大きくなり、装用感がよくなる。更に、耳せんに凹凸がないので、清掃し易い。 According to the first aspect of the present invention, since the substantially spherical earplug or the substantially elliptical earplug does not have an umbrella portion, it does not get caught in the ear canal and can be attached and detached smoothly. Moreover, in the substantially spherical earplug, the degree of freedom of the insertion angle into the ear canal is increased, and the feeling of wearing is improved. Furthermore, since there is no unevenness in the earplug, it is easy to clean.

請求項２に係る発明によれば、弾性体の性質により外耳道形状に合った形状に圧縮変形するので、しわになり難く、大きな音を出力してもハウリングし難い。 According to the second aspect of the present invention, since it is compressed and deformed into a shape suitable for the shape of the external auditory canal due to the properties of the elastic body, it is difficult to wrinkle and it is difficult to perform howling even if a loud sound is output.

以下に本発明の実施の形態を添付図面に基づいて説明する。ここで、図１は本発明に係る耳かけ形補聴器の概要斜視図、図２は略球形状の耳せんの断面図、図３は略楕円球形状の耳せんの説明図である。 Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a schematic perspective view of an ear-shaped hearing aid according to the present invention, FIG. 2 is a sectional view of a substantially spherical earplug, and FIG. 3 is an explanatory diagram of a substantially elliptical earplug.

本発明に係る耳かけ形補聴器１は、図１に示すように、補聴器本体２、フック３、チューブ４、ジョイント５、耳せん６からなる。７は電池ホルダである。補聴器本体２には、補聴処理部としてのＤＳＰ（Digital Signal Processor）、マイクロホン、イヤホンなどが収納されている。 As shown in FIG. 1, the behind-the-ear hearing aid 1 according to the present invention includes a hearing aid body 2, a hook 3, a tube 4, a joint 5, and an earplug 6. 7 is a battery holder. The hearing aid main body 2 houses a DSP (Digital Signal Processor), a microphone, an earphone and the like as a hearing aid processing unit.

耳せん６は、図２に示すように、略球形状をしている。また、図３に示すように、耳せん１６を、音道１７に垂直な断面が略楕円形状である略楕円球形状にすることもできる。そして、耳せん６，１６は、シリコンゴムや合成ゴム（ＮＢＲ）などの弾性体で形成されている。 The earplug 6 has a substantially spherical shape as shown in FIG. In addition, as shown in FIG. 3, the earplug 16 can be formed into a substantially elliptical sphere shape whose cross section perpendicular to the sound path 17 is a substantially elliptical shape. The earplugs 6 and 16 are formed of an elastic body such as silicon rubber or synthetic rubber (NBR).

以上のように構成された本発明に係る耳かけ形補聴器１の作用について説明する。略球形状の耳せん６または略楕円球形状の耳せん１６には、従来の耳せんに形成されている傘部がないので、外耳道に対して耳かけ形補聴器１を着脱する際に、外耳道に引っ掛かることがなく、着脱を円滑に行うことができる。特に、略球形状の耳せん６では、外耳道への挿入角度の自由度が大きいので、装着が円滑に行われると共に、装用感がよい。 The operation of the behind-the-ear hearing aid 1 according to the present invention configured as described above will be described. The substantially spherical auricle 6 or the substantially elliptical auricle 16 does not have an umbrella portion formed in the conventional ear canal. Can be smoothly attached and detached. In particular, the substantially spherical earplug 6 has a high degree of freedom in the angle of insertion into the ear canal, so that it can be worn smoothly and has a good feeling of wear.

また、耳せん６，１６は、弾性体で形成されているので、装用した状態において外耳道の形状に合った形状に圧縮変形する。従って、耳せん６，１６と外耳道の壁面との間に隙間が生じ難いので、大きな音を出力してもハウリングし難い。 Further, since the earplugs 6 and 16 are formed of an elastic body, the earplugs 6 and 16 are compressed and deformed into a shape that matches the shape of the ear canal when worn. Therefore, since a gap is not easily generated between the earplugs 6 and 16 and the wall of the ear canal, it is difficult to perform howling even if a loud sound is output.

また、略球形状の耳せん６にイヤホンを内蔵することもできる。同様に、略楕円球形状の耳せん１６にもイヤホンを内蔵することができる。更に、耳せん６，１６を小さくして、オープンフィッティングに使ってもよい。 Further, the earphone can be built in the substantially spherical earplug 6. Similarly, the earphone 16 can also be incorporated in the substantially elliptical earplug 16. Furthermore, the earplugs 6 and 16 may be made smaller and used for open fitting.

本発明によれば、外耳道に引っ掛かることがなく、着脱が円滑で装用感に優れた耳かけ形補聴器を提供することができるので、需要拡大が図れる。 According to the present invention, it is possible to provide an over-the-ear hearing aid that does not get caught in the ear canal, is smoothly attached and detached, and has a good wearing feeling, so that demand can be increased.
