Description

【0001】
【発明の属する技術分野】
本発明は、補聴器ケースの背面に補聴器の機能を選択するプッシュスイッチを備えた耳かけ形補聴器に関する。
【0002】
【従来の技術】
外部音に基づくアナログ電気信号をデジタル電気信号に変換して補聴処理し、補聴処理した信号を音響信号として出力する耳かけ形補聴器が知られている。この種の補聴器には、使用環境に適応するために複数の補聴処理プログラムの中から所望な補聴処理プログラムを選択するためのプッシュスイッチが設けられている。
【0003】
例えば、プッシュスイッチを備えた耳かけ形補聴器としては、図6に示すように、装用しながらのスイッチ操作を容易にするため、補聴器ケース100の背面101にプッシュスイッチの操作子102を突出させると共に、外部に露出して設けたものが知られている。
【0004】
【発明が解決しようとする課題】
しかし、従来の耳かけ形補聴器においては、プッシュスイッチの操作子102が補聴器ケース100の背面101から突出しているので操作性はよいものの、露出しているため操作子102と補聴器ケース100の隙間から装用者の汗などが浸入し、内部の構成部品の機能を低下させるという問題があった。
【0005】
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、プッシュスイッチに対する操作性を損うことなく、補聴器ケース内に装用者の汗などが浸入することがない耳かけ形補聴器を提供しようとするものである。
【0006】
【課題を解決するための手段】
上記課題を解決すべく請求項1に係る発明は、補聴器ケースの背面に補聴器機能を選択するプッシュスイッチを備えた耳かけ形補聴器において、前記プッシュスイッチを柔軟性のあるカバー部材で覆い、このカバー部材の周縁部に突出部を設け、この突出部により前記カバー部材と前記補聴器ケースとの接触部を密着構造にしたものである。
【0007】
請求項2に係る発明は、補聴器ケースの背面に補聴器機能を選択するプッシュスイッチを備えた耳かけ形補聴器において、前記補聴器ケースの背面に開口したスイッチ類収納部を設け、このスイッチ類収納部に前記プッシュスイッチを配置すると共に、前記スイッチ収納部を柔軟性のあるカバー部材で覆い、このカバー部材の周縁部に前記スイッチ類収納部の内壁部と嵌合する突出部を設け、この突出部と前記スイッチ類収納部の内壁部とが密接状態になるようにしたものである。
また、請求項3に係る発明は、請求項2記載の耳かけ形補聴器において、前記スイッチ類収納部は、補聴器ケースの背面に突出して配置したボリュームと電源スイッチとの谷間に設けたものである。
【0008】
【発明の実施の形態】
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ブロック構成図、図2は本発明に係る耳かけ形補聴器の斜視図、図3は図2においてカバー部材を取り外した状態の耳かけ形補聴器の斜視図、図4はカバー部材を示し(a)は平面図、(b)は(a)のX−X線断面図、(c)は(a)のY−Y線断面図、図5はカバー部材の補聴器ケースへの取付状態を示す断面図である。
【0009】
本発明に係る耳かけ形補聴器は、図1に示すように、マイクロホン1、プログラム記憶部2、プログラム選択部3、補聴処理部4、増幅器5、イヤホン6などを備えている。7はプッシュスイッチである。
【0010】
マイクロホン1は、外部音を音響電気変換してアナログ信号を出力する。プログラム記憶部2は、各種の使用環境に適応するための複数の補聴処理プログラムを記憶している。プログラム選択部3は、プログラム記憶部2が記憶している複数の補聴処理プログラムの中からプッシュスイッチ7の操作によって所望の補聴処理プログラムを選択し、それを補聴処理部4に出力する。
【0011】
補聴処理プログラムの選択は、プッシュスイッチ7が押圧されて出力するオン信号(例えば、ハイレベル信号)の数(押圧回数)をプログラム選択部3が認識し、その数に対応する補聴処理プログラムをプログラム記憶部2から読み出すことで行われる。即ち、プッシュスイッチ7を押圧することにより、その押圧回数に応じて順次その押圧回数に対応する補聴処理プログラムが選択され、補聴処理部4に出力される。
【0012】
補聴処理部4は、マイクロホン1が出力したアナログ信号をデジタル信号に変換し、このデジタル信号をプログラム選択部3が出力した補聴処理プログラムに基づいて処理し、処理した信号をアナログ信号に変換して出力する。
増幅器5は、補聴処理部4が出力したアナログ信号を増幅し、イヤホン6は増幅器5が出力したアナログ信号を電気音響変換して音響信号を出力する。
【0013】
また、本発明に係る耳かけ形補聴器は、図2又は図3に示すように、マイクロホン1、プログラム記憶部2、プログラム選択部3、補聴処理部4、増幅器5、イヤホン6などを補聴器ケース8内に収納すると共に、補聴器ケース8の背面8aに利得調節用ボリューム9と電源スイッチ10を突出して配置している。
【0014】
更に、ボリューム9と電源スイッチ10との間に、プッシュスイッチ7を収納するための開口したスイッチ類収納部11を設けている。なお、12はスイッチ類収納部11の開口を覆うカバー部材、13はフック、14はウインドカバー、15は電池ホルダである。
【0015】
スイッチ類収納部11には、補聴特性、例えば音質などを切り換える複数の回転式操作子16も配置されている。また、スイッチ類収納部11を覆うカバー部材12としては、柔軟性を有する材料、例えばデュポン社製のハイトレルなどの樹脂が適用される。
【0016】
カバー部材12は、図4(a)に示すように、楕円形状に形成されたカバー部12aの一端に係止部12bを、他端に係合部12cを設け、カバー部12aの周縁部にスイッチ類収納部11の内壁部と嵌合する突出部12dを設けている。12eは、カバー部12aの他端上面に形成したフック部である。
【0017】
また、図4(b)に示すように、カバー部材12の中央裏面には、プッシュスイッチ7を押圧する押圧部12fが形成され、押圧部12fと突出部12dの間は厚みを薄くしてバネ部12gとしている。
更に、図4(c)に示すように、係止部12bは、逆T字状に形成され、突出部12dの下端側の外径は、下方に行くにつれ僅かではあるが大きく形成されている。
【0018】
カバー部材12を補聴器ケース8に取り付けてスイッチ類収納部11を覆った状態では、図5に示すように、係止部12bの逆T字状の先端は、補聴器ケース8の内部に形成した穴部(不図示)に嵌め込まれている。これにより、一旦嵌め込めば、カバー部材12は補聴器ケース8から容易には脱落しない。
【0019】
ここで、スイッチ類収納部11の横断面形状は、カバー部材12の横断面形状と比較して僅かに大きめに形成されているので、突出部12dが僅かに弾性変形した状態でスイッチ類収納部11の内壁部と接触することになる。これにより、スイッチ類収納部11の内壁部と突出部12dの先端部とが密接状態になり、汗などがスイッチ類収納部11に浸入する虞がなくなる。
【0020】
また、この時、カバー部材12の係合部12cはスイッチ類収納部11の内壁部に形成された係合穴11aに嵌め込まれることになるので、カバー部材12の表面に、繰り返し押圧力が作用したとしても、カバー部材12がスイッチ類収納部11から外れることがない。
カバー部材12を開ける場合は、カバー部材12の上面に形成したフック部12eを爪などで引っ掛けて引き起こすようにすればよい。
【0021】
プログラム記憶部3が記憶する複数の補聴処理プログラムの中から所望な補聴処理プログラムを選択する場合には、カバー部材12の表面を所定の回数だけ押圧すればよい。そうすれば、所望な補聴処理プログラムが補聴処理部4に出力される。
【0022】
また、補聴器ケース8の背面8aに突出して配置されているボリューム9と電源スイッチ10との谷間に設けたスイッチ類収納部11にプッシュスイッチ7を配置しているので、指の感触だけで押圧すべき位置、即ちプッシュスイッチ7の位置が容易に確認できる。従って、耳かけ形補聴器を装着した状態で、プッシュスイッチ7のを押圧操作がより容易となる。
【0023】
更に、開閉自在のカバー部材12で覆うスイッチ類収納部11内にプッシュスイッチ7の他に、音質などを切り換える複数の回転式の操作子16を配置しているので、結果として耳かけ形補聴器の限られた背面のスペースを有効に使える。
【0024】
本発明は、上述した実施の形態に限定されるものでなく、種々の変形が考えられる。
【0025】
例えば、上述の実施の形態においては、補聴器ケース8の背面8aに開口したスイッチ類収納部11にプッシュスイッチ7も配置し、スイッチ類収納部11をカバー部材12で覆う構成とした。
しかし、弾性的に撓み変形するカバー部材を介してプッシュスイッチ7を押圧操作できればよいのであるから、スイッチ類収納部11を設けることなく補聴器ケースの表面にプッシュスイッチ7を配置し、ドーム状に成型したカバー部材で覆うようにしてもよい。もちろん、この場合もカバー部材と補聴器ケースとで形成される隙間から汗などが浸入しないように配慮する必要がある。
【0026】
また、上述の実施の形態においては、プッシュスイッチ7は、プログラム記憶部2が記憶する複数の補聴処理プログラムから一つの補聴処理プログラムを選択する機能を有するものとして説明した。
しかし、その他の補聴特性を選択する機能を有するものとしてもよい。その他の補聴特性としては、音質調整、周波数特性調整などがある。また、補聴処理部4へ入力信号としてマイクロホンの出力信号とするかテレホンコイルの出力信号とするかの入力選択の機能を持たせてもよい。
【0027】
【発明の効果】
以上説明したように請求項1に係る発明によれば、カバー部材を押圧するだけでプッシュスイッチを操作することができるので、プッシュスイッチに対する操作性を損うことない。
また、カバー部材の周縁部に突出部を設け、この突出部によりカバー部材と補聴器ケースとの接触部を密着構造にしたので、装用者の汗などが補聴器ケース内へ浸入するのを防止することができる。
【0028】
請求項2に係る発明によれば、補聴器ケースの背面から突出させることなくプッシュスイッチを設けることができので、外観上の見栄えが向上する。
また、カバー部材を押圧するだけでプッシュスイッチを操作することができるので、プッシュスイッチに対する操作性を損うことがない。
更に、カバー部材の周縁部にスイッチ類収納部の内壁部と嵌合する突出部を設け、この突出部とスイッチ類収納部の内壁部とが密接状態になるようにしたので、装用者の汗などが補聴器ケース内に浸入するのを防止することができる。
また、請求項3に係る発明によれば、スイッチ類収納部を、補聴器ケースの背面に突出して配置したボリュームと電源スイッチとの谷間に設けたので、指の感触だけで押圧すべき位置、即ちプッシュスイッチの位置が容易に確認できる。従って、耳かけ形補聴器を装着した状態で、プッシュスイッチのを押圧操作がより容易となる
