Abstract
【解決手段】 弾性高分子膜とマイクロホン4により形成されるマイクロホン室18と補聴器ケース3により形成される補聴器ケース室22を連通する通気孔(第1通気手段)55をマイクロホンケース30に設けた。
【選択図】 図9
Description
また、挿耳型補聴器の防水構造として、補聴器の音響出口接続部に穴付きキャップを取り付け可能にし、このキャップ内には不粘着性ポリテトラフルオロエチレン製の微孔質の膜を配設して、音響を透過し易くすると共に、耳道からの耳垢、湿気や汗などが補聴器内に浸入するのを防ぐ構造が知られている(例えば、特許文献2参照)。
更に、微孔質の膜の代わりに音響伝搬のよい材料、0.01mm以下のチタンなどからなる無孔のダイアフラムを用いた防護器具を音響入口の開口部及び音響出口の開口部に設けた補聴器が知られている(例えば、特許文献3参照)。
図5に示すように、フェースプレート2には、マイクロホン4の音入口5、音入口5と連通するマイクロホン4の取付孔6、電池7を保持した電池蓋8が収まる電池蓋収納部9などが形成されている。また、シェル1の先端には、イヤホン11の音出口12と、音出口12と連通するイヤホン11の取付孔13が形成されている。
従って、補聴器ケース室22の気圧は、防水性を犠牲にすることなく、できるだけ短時間で外部の気圧と平衡になることが望ましい。
従って、これらの通気性は数秒以下の短時間で気圧の平衡が取れ、且つ通気手段がない場合と比較して特性上変化が無視できる程度に音響インピーダンスが大きくなるように決められる。図5に示すチューブ(第1通気手段)27とチューブ(第2通気手段)28の場合は、共に内径0.1mm、長さ10mmを用いた。
