Abstract

<P>PROBLEM TO BE SOLVED: To provide a hearing aid which eliminates a closed feeling and discomfort and prevents generation of hauling by ensuring permeability of external air with a surface of the eardrum without sealing the external auditory meatus. <P>SOLUTION: In a behind-the-ear hearing aid, an external air introduction tube 15 is formed by connecting a tube to an audio path from the main body of a case 11 to an earplug (ear chip) 22 mounted on the external auditory meatus. Furthermore, an opening is provided on a bottom of the main body of the case 11, this opening and the audio path are connected, thereby forming the external air introduction tube 15. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は外耳道の密閉感や、閉塞感、こもり感をなくし装着による不快感を解消し快適な装着感を実現する補聴器に関する。The present invention relates to a hearing aid that eliminates the discomfort caused by wearing and eliminates the feeling of sealing, blockage, and bulkiness of the external auditory canal, thereby realizing a comfortable wearing feeling.

従来から補聴器として、箱形、耳かけ形及び耳穴式などがあり、どの形式も音出力部としての耳栓を外耳道入口に挿入し、音漏れによるハウリングを防ぐため密着した状態で使用。Conventional hearing aids include box-type, ear-hook type, and ear-hole type, and all types are used in close contact to prevent howling due to sound leakage by inserting an ear plug as a sound output part into the ear canal entrance.

耳栓（イヤーチップ）を外耳道入口に密着装用した場合、ハウリングの発生は防止できるが、外耳道の密閉により装用者に不快感を生じさせていた。When the ear plug (ear tip) is worn closely to the entrance to the ear canal, howling can be prevented, but the outer ear canal is sealed, causing discomfort to the wearer.

今日までの技術が持つこのような問題点に試行錯誤し取り組んだ本発明は、外耳道を密閉状態にすることなく鼓膜面と外気の通気を確保し、ハウリングがなく快適に装用できる補聴器を提供しようとするものである。The present invention, which has been tackled with such problems of the technology to date, will provide a hearing aid that can be comfortably worn without howling, ensuring the ventilation of the eardrum surface and the outside air without sealing the ear canal. It is what.

課題の解決として請求項１の発明は、耳かけ形補聴器本体部より延出するチューブ（音道）に取り付けるＹ字形チューブ及び耳栓（イヤーチップ）で構成し、Ｙ字形チューブの一方を耳かけ形補聴器本体後方まで延長外気導入管とし、その先端を開放（オープンエアー）する、もう一方の先端に外耳道の入口に装着する耳栓（イヤーチップ）を備えるようにした。As a solution to the problem, the invention of claim 1 is composed of a Y-shaped tube and an earplug attached to a tube (sound path) extending from the ear-hook type hearing aid main body, and one of the Y-shaped tubes is hooked. The outside air introduction tube was extended to the rear of the main body of the hearing aid, and the ear tip (ear tip) attached to the entrance of the ear canal was provided at the other tip, which opened the open end (open air).

請求項２の発明は、請求項１に記載した補聴器のケース本体部より延出するチューブ（音道）よりＹ字形チューブにより分岐した外気導入管を分岐させることなく、ケース本体底部と音道をつなぎ外気導入管を形成し、それをケースに内蔵するようにした。In the invention of claim 2, the bottom of the case body and the sound path are connected without branching the outside air introduction pipe branched by the Y-shaped tube from the tube (sound path) extending from the case body of the hearing aid according to claim 1. A connecting outside air introduction tube was formed and incorporated in the case.

以下に本発明の実施の形態について説明する。
図１は本発明請求項２に係る耳かけ式補聴器（外気導入管内臓）の装着状態を示す図、図２は本発明請求項１に係る耳かけ式補聴器の全体外略図、図３は耳かけ式補聴器の本発明請求項２にかかる要部の構造を示す図である。Embodiments of the present invention will be described below.
FIG. 1 is a diagram showing a wearing state of an ear-hearing hearing aid (built-in external air introduction tube) according to claim 2 of the present invention, FIG. 2 is an overall schematic view of the ear-hearing hearing aid according to claim 1 of the present invention, and FIG. It is a figure which shows the structure of the principal part concerning Claim 2 of this invention of a type hearing aid.

以上説明したように本発明によれば、ハウリングを防止し、外耳道を密閉することなく通気性を確保でき、装用による不快感を生ずることがない。As described above, according to the present invention, howling is prevented, air permeability can be secured without sealing the ear canal, and discomfort due to wearing does not occur.

また本発明は構造が簡単で、清掃などのメンテナンスについて省力化が図れ、特別な機器等使用していないため安価に製造でき省資源化が図れる。Further, the present invention has a simple structure, can save labor for maintenance such as cleaning, and can be manufactured at low cost and can save resources because no special equipment is used.

本発明は通気性を確保し、更にハウリングを発生させないため騒音の中でも聞き取りの効果が大きい。Since the present invention ensures air permeability and does not generate howling, the listening effect is great even in noise.
