Description

【０００１】
【発明の属する技術分野】
本発明は人の耳に装着する耳装着型の音情報伝達器に関する。
【０００２】
【従来の技術】
この種の音情報伝達器では耳への安定装着が望まれることから、図１０に示す如く、耳甲介腔部Ｙへ挿着する本体部ＭＥとともに、この本体部ＭＥとの間で耳甲介腔部Ｙの縁部Ｙｆを挟持する挟持部ＣＥを器体に設け、この挟持により耳への安定装着を図ったものを先に提案した（特願平８−１０７２１１号参照）。
【０００３】
【発明が解決しようとする課題】
しかし、この挟持部ＣＥの付設により耳への装着の安定性は全体としてかなり向上したが、人によって耳の形状は多様であるため、挟持対象である耳甲介腔部Ｙの縁部Ｙｆが薄い人や、耳甲介腔部Ｙが大きくて本体部ＭＥの挿着そのものが一般より不安定な人については、挟持が不十分で装着安定性の向上が期待ほどは得られない場合があり、この点、未だ改善の余地があった。
【０００４】
以上の実情に対し、本発明の主たる課題は、合理的な補助具の付加により、挟持部だけでは挟持が不十分な人についても、満足な装着安定性を簡便に得られるようにする点にある。
【０００５】
【課題を解決するための手段】
〔１〕請求項１記載の発明では、器体が、耳甲介腔部に挿着する本体部と、この本体部との間で耳甲介腔部の縁部を挟持する挟持部とを備えるのに対し、この器体に挟持補強具を装着して、この挟持補強具に具備の当て部を器体における挟持部のうち耳甲介腔部の縁部に対向する部分に位置させることで、この当て部をもって、耳甲介腔部の縁部に対する本体部との間の挟持間隔を小さくし、これにより、耳甲介腔部の縁部に対する挟持を強くする。
【０００６】
したがって、挟持部だけでは挟持が不十分な人は、この挟持補強具を器体に装着するだけで簡便に耳甲介腔部の縁部に対する挟持を強くして満足な装着安定性を得ることができ、また逆に、挟持部だけで十分な挟持が得られる人については、この挟持補強具を器体から取り外した状態で使用することで、挟持が強すぎて不快感を生じるといったことなく、満足な装着安定性を得ることができる。
【０００７】
〔２〕請求項２記載の発明では、器体が、耳甲介腔部に挿着する本体部と、この本体部から延出して耳甲介腔部の外部に位置する付帯部と、本体部と付帯部との境界部付近から延出して本体部との間で耳甲介腔部の縁部を挟持する弾性変位可能な挟持部とを備えるのに対し、この器体に挟持補強具を装着して、この挟持補強具に具備の詰め部を器体における挟持部と付帯部との間に挟み込み位置させることで、この詰め部をもって、本体部との間の挟持間隔が拡大する側への挟持部の弾性変位の剛性を高くし、これにより、耳甲介腔部の縁部に対する挟持を強くする。
【０００８】
したがって、前記した請求項１記載の発明と同様、挟持部だけでは挟持が不十分な人は、この挟持補強具を器体に装着するだけで簡便に耳甲介腔部の縁部に対する挟持を強くして満足な装着安定性を得ることができ、また逆に、挟持部だけで十分な挟持が得られる人については、この挟持補強具を器体から取り外した状態で使用することで、挟持が強すぎて不快感を生じるといったことなく、満足な装着安定性を得ることができる。
【０００９】
〔３〕請求項３記載の発明では、器体が、耳甲介腔部に挿着する本体部と、この本体部から延出して耳甲介腔部の外部に位置する付帯部と、本体部と付帯部との境界部付近から延出して本体部との間で耳甲介腔部の縁部を挟持する弾性変位可能な挟持部とを備えるのに対し、この器体に挟持補強具を装着して、この挟持補強具に具備の当て部を器体における挟持部のうち耳甲介腔部の縁部に対向する部分に位置させ、かつ、同じく挟持補強具に具備の詰め部を器体における挟持部と付帯部との間に挟み込み位置させることで、これら当て部及び詰め部をもって、耳甲介腔部の縁部に対する本体部との間の挟持間隔を小さくするとともに、その挟持間隔が拡大する側への挟持部の弾性変位の剛性を高くし、これにより、耳甲介腔部の縁部に対する挟持を強くする。
【００１０】
したがって、前記した請求項１記載の発明や請求項２記載の発明と同様、挟持部だけでは挟持が不十分な人は、この挟持補強具を器体に装着するだけで簡便に耳甲介腔部の縁部に対する挟持を強くして満足な装着安定性を得ることができ、また逆に、挟持部だけで十分な挟持が得られる人については、この挟持補強具を器体から取り外した状態で使用することで、挟持が強すぎて不快感を生じるといったことなく、満足な装着安定性を得ることができる。
【００１１】
また、本体部との間の挟持間隔を小さくすることと、その挟持間隔が拡大する側への挟持部の弾性変位の剛性を高めることとの相乗作用をもって、耳甲介腔部の縁部に対する挟持を強くするから、単に挟持間隔を小さくするだけ、あるいは、単に挟持部の弾性変位の剛性を高めるだけに比べ、より高い挟持強度を確実かつ効果的に得ることができる。
【００１２】
〔４〕請求項４記載の発明では、挟持補強具における前記詰め部を器体における挟持部と付帯部との間に挟み込んだ状態において、この詰め部による押圧をもって、挟持部を耳甲介腔部の縁部に対する本体部との間の挟持間隔が小さくなる側へ弾性変位させるから、挟持補強具を装着した際は、この挟持間隔の縮小と、詰め部の基本機能として前述の如く挟持間隔が拡大する側への挟持部の弾性変位の剛性を高くすることとの相乗作用をもって、耳甲介腔部の縁部に対する高い挟持強度を確実かつ効果的に得ることができる。
【００１３】
〔５〕請求項５記載の発明では、挟持補強具に形成した嵌着部を器体の挟持部に外嵌状態で嵌着させて、挟持補強具を器体に装着する構成とするから、すなわち、挟持補強具の嵌着部を器体の挟持部に対し外嵌状態に嵌め込むことで挟持補強具を器体に装着し、また、この嵌め込みを外すことで挟持補強具を器体から取り外すようにするから、器体に対する挟持補強具の着脱を簡便に行うことができる。
【００１４】
〔６〕請求項６記載の発明では、挟持補強具に形成した嵌着部を器体の付帯部に外嵌状態で嵌着させて、挟持補強具を器体に装着する構成とするから、前記した請求項５記載の発明と同様、器体に対する挟持補強具の着脱を簡便に行うことができる。
【００１５】
〔７〕請求項７記載の発明では、挟持補強具に形成した第１嵌着部を挟持部に外嵌状態で嵌着させ、かつ、挟持補強具に形成した第２嵌着部を付帯部に外嵌状態で嵌着させて、挟持補強具を器体に装着する構成とすることにより、前記した請求項５記載の発明や請求項６記載の発明と同様、器体に対する挟持補強具の着脱を簡便に行うことができる。また、二つの嵌着部を器体の二箇所に嵌着させて挟持補強具を装着するから、器体に装着した挟持補強具の保持をより確実にすることができる。
【００１６】
〔８〕請求項８記載の発明では、挟持補強具を器体に装着してその器体における本体部を耳甲介腔部に挿着した状態で、挟持補強具を含む器体の重心が、本体部と挟持部とで挟持する耳甲介腔部の縁部を支点として本体部を耳甲介腔部の内方向きに重力付勢する位置に位置する構成とすることにより、装着した挟持補強具の荷重も合わせ利用するこの器体荷重利用の耳甲介腔部内方向きへの本体部付勢をもって装着安定性を向上でき、挟持補強具の当て部や詰め部により前述の如く耳甲介腔部の縁部に対する挟持を強くすることと相まって、挟持部だけでは不十分な人に対する装着安定性を一層効果的に高めることができる。
【００１７】
なお、以上の各発明の実施にあたっては、次のイ．〜ト．の構成を選択的に採用することが好ましい。
【００１８】
イ．前記当て部を弾性材で形成する。すなわち、この構成によれば、当て部の弾性をもって耳甲介腔部の縁部に対し当て部を良好にフィットさせることができ、これにより、装着安定性の向上を促進し得るとともに装着感覚を向上できる。また、当て部による挟持間隔の縮小で挟持を強くするようにしながらも、当て部の弾性をもって得られる融通により種々の耳形状に対する挟持補強具の適用範囲を広くすることができる。
【００１９】
ロ．耳甲介腔部の縁部に対する前記当て部の当接面を、上下中間部が耳甲介腔部の縁部の側へ膨出する湾曲面に形成する。すなわち、この構成によれば、当て部の膨出湾曲面を耳甲介腔部の縁部における外面側の窪み部に入り込ませる形態で当て部を耳甲介腔部の縁部に当接させて耳甲介腔部の縁部を挟持でき、これをもって、装着安定性の向上を促進できる。
【００２０】
ハ．挟持補強具における前記詰め部を弾性材で形成する。すなわち、この構成によれば、詰め部の基本機能として挟持間隔が拡大する側への挟持部の弾性変位の剛性を高くして挟持を強くするようにしながらも、詰め部の弾性をもって挟持部の弾性変位機能を残す状態で、挟持補強具の装着時も、挟持部を弾性的に耳甲介腔部の縁部に当接させるようにして良好な装着感覚を得ることができる。また、このように挟持部の弾性変位機能を残すことで得られる融通により種々の耳形状に対する挟持補強具の適用範囲を広くすることができる。
【００２１】
ニ．挟持補強具における前記詰め部をくさび形状に形成し、このくさび形状の先端側を先方にして詰め部を器体における挟持部と付帯部との間へ差し込む形態で、挟持補強具を器体に装着する構成とする。
【００２２】
すなわち、この構成によれば、くさび形状によるくさび効果をもって、挟持部と付帯部との間への詰め部の差し込みを容易にしながら、詰め部を挟持部と付帯部との間に的確に挟み込み位置させることができ、前述の如き詰め部の所期機能を確実に発揮させることができる。
【００２３】
ホ．本体部からの延出ケーブルを挿通するパイプ部を前記の付帯部とし、挟持補強具を器体に装着した状態において、挟持補強具の詰め部を、このパイプ部と挟持部との間に挟み込み位置させる。
【００２４】
すなわち、器体において上記パイプ部は、耳甲介腔部に挿着する本体部の耳外側端部から耳甲介腔部の外側で下方向きに延出する形態となることから、耳甲介腔部の縁部を本体部との間で挟持する挟持部とは極近傍で隣合う位置関係となり、このことから、上記の如くパイプ部を付帯部として、このパイプ部と挟持部との間に挟持補強具の詰め部を挟み込み位置させる構成とすることで、詰め部そのものに要求される大きさを小さくして、挟持補強具をコンパクトにすることができる。
【００２５】
また、挟持補強具に形成した嵌着部を付帯部に嵌着させて挟持補強具を器体に装着する構成を採用するについても、パイプ部を付帯部として、このパイプ部に挟持補強具の嵌着部を嵌着させる構成とすれば、上記の如くパイプ部と挟持部とが極近傍で隣合う位置関係にあることに伴い、挟持補強具における詰め部と嵌着部も極近傍で隣合う位置関係となり、これにより、挟持補強具を一層効果的にコンパクト化できる。
【００２６】
ヘ．耳部の軟骨に伝わる骨伝導音声を検出する送信用素子を前記本体部に装備する。すなわち、この構成によれば、使用者自身の骨伝導音声を検出し電気信号に変換して必要な所へ送信するといったことが可能になる。
【００２７】
そして、この使用形態において、挟持補強具を器体に装着すれば、器体の挟持部だけでは挟持が不十分な人についても、耳甲介腔部の縁部に対する挟持を強くして本体部と耳甲介腔部との接触圧を大きくし得ることにより、耳甲介腔部の表面に極微小な振動として伝播する骨伝導音声を感度良く検出することができ、骨伝導音声を良好に送信できるようになる。
【００２８】
また、前記した請求項８記載の発明に並行して実施すれば、耳甲介腔部の内方向きへ本体部を重力付勢することが、本体部と耳甲介腔部との接触圧を大きくすることに寄与することから、骨伝導音声の検出感度を一層効果的に向上させることができる。
【００２９】
ト．受信用のイヤホーンを前記本体部に装備する。すなわち、この構成によれば、電気信号で送られてくる音声などの音情報をイヤホーンからの放音で聴取することができる。
【００３０】
そして、この使用形態において、挟持補強具を器体に装着すれば、器体の挟持部だけでは挟持が不十分な人についても、高い装着安定性を得られることで良好な聴取状態を安定的に維持できるようになる。
【００３１】
また、前記したへ．の構成を並行して実施すれば、耳甲介腔部への本体部の挿着だけで送信と受信を行うことができ、人と人との通話に用いる場合、極めてコンパクトな通話器を実現できる。
【００３２】
【発明の実施の形態】
図５及び図６は骨伝導音声利用の通話器を示し、器体には、図１２に斜線で示す耳の耳甲介腔部Ｙに装着する本体部ＭＥと、付帯部として本体部ＭＥの耳外側端部から下方に延出して耳甲介腔部Ｙの外部に位置させる電線挿通用のパイプ部ＰＥと、これら本体部ＭＥとパイプ部ＰＥとの境界部付近から舌片状に下方へ延出する挟持部ＣＥとを設けてあり、図１０に示すように、耳への装着状態では、本体部ＭＥを耳甲介腔部Ｙへ挿着するに加え、本体部ＭＥと挟持部ＣＥとをもって、これら両部ＭＥ，ＣＥの間で耳甲介腔部Ｙの縁部Ｙｆを挟持することで、耳への装着の安定性を高めるようにしてある。
【００３３】
なお、耳甲介腔部Ｙの縁部Ｙｆとは、同図１０及び図１１に示すように、耳珠５０と対珠５１との繋がり部に存在する延出部分のことである。
【００３４】
本体部ＭＥは、互いに離間させて上下に配置した第１及び第２ハウジング１，６を耳外側端部で支持部材２に連結した二股構造にし、これら第１及び第２ハウジング１，６のうち上部側の第２ハウジング６に受信用イヤホーン８を内装支持することにより、通話相手側からの音声信号を音声に変換して外耳道５３へ向け出力するイヤホーン部ＲＥを構成してある。４は受信用イヤホーン８の前面を覆う状態で第２ハウジング６の耳内側開口部に取り付けたプロテクタである。
【００３５】
また、イヤホーン部ＲＥを構成するにあたり、第２ハウジング６は、受信用イヤホーン８から伝わる微振動を減衰させる制振手段ＶＡとしての機能を兼ねるように、黄銅などの比重の大きな金属で形成してあり、さらに、第２ハウジング６から支持部材２への微振動伝播も抑止するように、第２ハウジング６は、プラスチック材をベースとする粘弾性体からなる減衰部材３を介して支持部材２に連結してある。
【００３６】
一方、本体部ＭＥにおける第１ハウジング１には、図５及び図８に示すように、耳甲介腔部Ｙの内方側に位置させる大径部分１ａと、この大径部分１ａから支持部材２にわたる小径部分１ｂとを形成してあり、送信用素子として骨伝導音声検出用の圧電素子１２を大径部分１ａに内装支持するとともに、電界効果型トランジスタ１３を搭載する基板１０を小径部分１ｂに内装支持することにより、人の耳部に伝わる骨伝導音声（発声に伴い骨伝導により声帯から耳部に伝わる音声振動）を検出する骨伝導音声ピックアップ部ＳＥを構成してある。
【００３７】
圧電素子１２は、耳甲介腔部Ｙの表面から第１ハウジング１（特に大径部分１ａ）に伝わる骨伝導音声の振動に伴い振動させて圧電効果により骨伝導音声の検出を行うように、その長手方向の一端のみを固定支持した片持ち支持状態で大径部分１ａに内装し、ケーブル１６により基板１０の回路と電気接続してあり、この圧電素子１２には、電極となる金属板を挟んで２枚の圧電セラミック材を張り合わせたバイモルフ型の圧電セラミック素子を使用し、小型化とともに微弱振動である骨伝導音声に対する検出感度の向上を図ってある。
【００３８】
また、圧電素子１２の全体をシールドケース１５で覆うことによりＳ／Ｎ比（信号雑音比）の向上を図り、このシールドケース１５を第１ハウジング１で覆うことにより外部からの傷害要因に対する保護を図ってある。
【００３９】
第１ハウジング１の大径部分１ａのうち、耳甲介腔部Ｙの底面Ｂに対する当接面部は、耳甲介腔部Ｙの底面Ｂとの接触面積を極力大きく確保するように、外耳道５３に沿う方向視で耳甲介腔部Ｙの底面Ｂ側に膨出する弧状の曲面形状に形成してあり、また、第１ハウジング１は、ＡＢＣ樹脂や塩化ビニル樹脂などの比較的保湿性の高い材料で形成するとともに、表面を磨き鏡面状に仕上げ、皮膚との密着性及び馴染み性の向上を図ってある。
【００４０】
図９は回路構成を示し、骨伝導音声信号としての圧電素子１２の出力電圧を電界効果型トランジスタ１３によりインピーダンス変換及び増幅した上で送信用ケーブル７へ出力し、また、受信用ケーブル９を介して入力する通話相手側からの音声信号を受信用イヤホーン８で音声信号に変換する。
【００４１】
送信用ケーブル７と受信用ケーブル９は一線を共通線としてあり、図５及び図７に示す如く、受信用ケーブル９は、受信用イヤホーン８から減衰部材３の配線挿通孔３ａ及び支持部材２の配線挿通孔２ａを介しパイプ部ＰＥに挿通してプラグ１４に接続し、送信用ケーブル７は、同じく支持部材２に形成の配線挿通孔（図示せず）を介しパイプ部ＰＥに挿通してプラグ１４に接続し、このプラグ１４により、これら送受信用のケーブル７，９を携帯電話やトランシーバなどの通信用機器に接続するようにしてある。
【００４２】
つまり、以上の構成により、この通話器を耳に装着した使用者が発声すると、その発声の際の声帯振動が顎や頭蓋骨などを介し骨伝導音声として耳部に伝わって、骨伝導音声ピックアップ部ＳＥで圧電素子１２により検出され、そして、この圧電素子１２で音声振動に対応する電気信号に変換されて、プラグ１４を接続した通話用機器により通話相手側へ送信される。
【００４３】
また、通話相手側からの音声信号が、プラグ１４を接続した通話用機器からイヤホーン部ＲＥの受信用イヤホーン８に入力され、そして、このイヤホーン８で音声に変換されて外耳道５３へ出力され鼓膜に達する。すなわち、この通話器を用いて通話を行うことにより、送信及び受信の双方について外部騒音の影響を殆ど受けずに通話できるようにしてある。
【００４４】
本体部ＭＥとの間で耳甲介腔部Ｙの縁部Ｙｆを挟持する舌片状の挟持部ＣＥは、硬度５０〜８０のゴムや塩化ビニルなどの弾性材で形成して撓み形態での弾性変位を可能にしてあり、これにより、耳甲介腔部Ｙの縁部Ｙｆに対する挟持を確実にしながら、耳甲介腔部Ｙの縁部Ｙｆに対する弾性的当接により良好な装着感覚を得られるように、また、種々の耳形状に対し適切に挟持できる対応可能範囲を広く確保するようにしてある。
【００４５】
さらに、この通話器では、耳甲介腔部Ｙの縁部Ｙｆが薄い人や、耳甲介腔部Ｙが大きくて本体部ＭＥの挿着そのものが不安定な人で、挟持部ＣＥだけでは挟持が緩く装着が不安定な場合、図１〜図４に示す如く、着脱自在な挟持補強具Ｈを器体に装着することで、耳甲介腔部Ｙの縁部Ｙｆに対する挟持を強くして満足な装着安定性を得られるようにしてある。
【００４６】
この挟持補強具Ｈは、図２に示す如く二股筒状のもので、ゴムや塩化ビニル、あるいは、スポンジなどの弾性材で形成してあり、二股筒のうちの一方の第１筒部ｈ１を第１嵌着部として挟持部ＣＥに外嵌状態で嵌着させ、かつ、他方の第２筒部ｈ２を第２嵌着部としてパイプ部ＰＥに外嵌状態で嵌着させて、器体に装着する。
【００４７】
そして、第１筒部ｈ１の横外側部分を挟持間隔縮小用の当て部Ａとして、器体への装着状態で、この当て部Ａを挟持部ＣＥのうち耳甲介腔部Ｙの縁部Ｙｆに対向する面部分に位置させることにより、耳甲介腔部Ｙの縁部Ｙｆに対する本体部ＭＥとの間の挟持間隔を小さくし、また、第１及び第２筒部ｈ１，ｈ２の間の股部分を剛性増強用の詰め部Ｔとして、器体への装着状態で、この詰め部Ｔを挟持部ＣＥとパイプ部ＰＥとの間に挟み込み位置させることにより、本体部ＭＥとの間の挟持間隔が拡大する側への挟持部ＣＥの弾性変位の剛性を高くし、これら挟持間隔の縮小と剛性の増強をもって、耳甲介腔部Ｙの縁部Ｙｆに対する挟持を強くするようにしてある。
【００４８】
耳甲介腔部Ｙの縁部Ｙｆに対する前記当て部Ａの当接面は、上下中間部が耳甲介腔部Ｙの縁部Ｙｆの側へ膨出する湾曲面に形成してあり、この当て部Ａの膨出湾曲面を耳甲介腔部Ｙの縁部Ｙｆにおける外面側の窪み部に入り込ませる形態で当て部Ａを耳甲介腔部Ｙの縁部に当接させて耳甲介腔部Ｙの縁部Ｙｆを挟持することにより、装着安定性の一層の向上を図ってある。
【００４９】
一方、詰め部Ｔはくさび形状に形成してあり、挟持部ＣＥ及びパイプ部ＰＥを二股筒の各筒孔部に挿入して挟持補強具Ｈを器体に装着する際、このくさび形状の先端側を先方にして詰め部Ｔを挟持部ＣＥとパイプ部ＰＥとの間へ差し込む形態とすることで、このとき生じるくさび効果により、挟持部ＣＥとパイプ部ＰＥとの間への詰め部Ｔの差し込みを容易にしながら、詰め部Ｔを挟持部ＣＥとパイプ部ＰＥとの間に的確に挟み込み位置させ得るようにしてある。
【００５０】
また、挟持補強具Ｈの全体を弾性材で形成して、当て部Ａ及び詰め部Ｔに弾性を備えさせることにより、装着安定性の一層の向上とともに、挟持補強具Ｈを用いた際も耳への装着感覚が良好に保たれるように、さらにまた、弾性をもって得られる融通により種々の耳形状に対する挟持補強具Ｈの適用範囲を広く確保できるようにしてある。
【００５１】
本体部ＭＥ、パイプ部ＰＥ、及び、挟持部ＣＥを備える器体を構成するにあたっては、前述の如く第２ハウジング６を比重の大きな金属材で形成するなどのことも利用した重心配置により、図１０に示す如く本体部ＭＥを耳甲介腔部Ｙに装着した状態において、器体の重心が、本体部ＭＥと挟持部ＣＥとで挟持する耳甲介腔部Ｙの縁部Ｙｆを支点として本体部ＭＥを耳甲介腔部Ｙの内方向きに重力付勢する位置に位置するように、換言すれば、耳甲介腔部Ｙの縁部Ｙｆの外縁よりも器体重心が耳内方側に位置するようにしてあり、また、図３に示す如く、挟持補強具Ｈを器体に装着した状態で本体部ＭＥを耳甲介腔部Ｙに装着した場合においても同様に、挟持補強具Ｈを含む器体の重心が、本体部ＭＥと挟持部ＣＥとで挟持する耳甲介腔部Ｙの縁部Ｙｆを支点として本体部ＭＥを耳甲介腔部Ｙの内方向きに重力付勢する位置に保たれるようにしてある。
【００５２】
つまり、この重力付勢により、挟持部ＣＥによる挟持と相まって、また、挟持補強具Ｈの使用による挟持強度の増強と相まって、一層高い装着安定性を得られるように、さらにまた、耳甲介腔部Ｙの底面Ｂと骨伝導音声ピックアップ部ＳＥとの接触面圧を大きくして骨伝導音声の検出感度を高めるようにしてある。
【００５３】
なお、挟持部ＣＥの下端には、重り装着部ＷＳとしての小孔を形成してあり、必要に応じ、この小孔ＷＳに適当な重量の重りＷＴを吊り下げることで、耳甲介腔部Ｙの底面Ｂと骨伝導音声ピックアップ部ＳＥとの接触面圧の一層の増強を図れるようにしてある。また、重りＷＴは種々の形状のものを使用でき、使用者の好みに応じ適宜交換してファッション性の向上に利用するなどしてもよい。この重りＷＴは前記の挟持補強具Ｈと同様、必要な場合のみ装着すればよく、不必要な場合は取り外しておく。
【００５４】
〔別実施形態〕
次に発明の別の実施形態を列記する。
挟持補強具Ｈの具体的形状・構造は種々の構成変更が可能であり、例えば、図１３及び図１４に示すように、筒部ｈ２を嵌着部としてパイプ部ＰＥに外嵌状態で嵌着させることにより器体に装着する単筒構造にし、そして、単筒構造において、筒部ｈ２の一側部分を剛性増強用の詰め部Ｔとして、器体への装着状態で、この詰め部Ｔを挟持部ＣＥとパイプ部ＰＥとの間に挟み込み位置させるものとしてもよい。
【００５５】
また、詰め部Ｔを挟持部ＣＥとパイプ部ＰＥとの間に挟み込み位置させて、本体部ＭＥとの間の挟持間隔が拡大する側への挟持部ＣＥの弾性変位の剛性を高くすることに加え、同図１４に示すように、詰め部Ｔを挟持部ＣＥとパイプ部ＰＥとの間に挟み込んだ状態において、この詰め部Ｔによる押圧をもって、挟持部ＣＥを本体部ＭＥとの間の挟持間隔が小さくなる側へ弾性変位させるようにしてもよい。
【００５６】
図１５及び図１６に示すように、筒部ｈ１を嵌着部として挟持部ＣＥに外嵌状態で嵌着させることにより器体に装着する単筒構造にし、そして、単筒構造において、筒部ｈ１の一側部分を挟持間隔縮小用の当て部Ａとして、器体への装着状態で、この当て部Ａを挟持部ＣＥのうち耳甲介腔部Ｙの縁部Ｙｆに対向する面部分に位置させ、かつ、筒部ｈ１の他側部分を剛性増強用の詰め部Ｔとして、器体への装着状態で、この詰め部Ｔを挟持部ＣＥとパイプ部ＰＥとの間に挟み込み位置させるものとしてもよい。
【００５７】
挟持補強具Ｈは、当て部Ａと詰め部Ｔのいずれか一方のみを備えるもの、あるいは、当て部Ａと詰め部Ｔの両方を備えるもののいずれであってもよく、挟持補強具Ｈの全体の構造・形状、当て部Ａや詰め部Ｔの細部の構造・形状も種々の構成変更が可能である。
【００５８】
挟持補強具Ｈの器体に対する装着構造も前述の如き外嵌状態での嵌着に限らず種々の構成変更が可能であり、着脱操作を容易に行える適当な連結具を用いて器体に装着する構造を採用してもよい。
【００５９】
前述の実施形態では、挟持部ＣＥを弾性変位可能にするのに、挟持部ＣＥそのものを弾性材で形成して弾性変位させるようにしたが、バネなどによる適当な弾性付勢手段をもって挟持部ＣＥを弾性変位自在に支持するようにしてもよい。
【００６０】
前述の実施形態では、挟持部ＣＥとパイプ部ＰＥとの間に挟持補強具Ｈの詰め部Ｔを挟む込み位置させる例を示したが、挟持部ＣＥとの間で挟持補強具Ｈの詰め部Ｔを挟み込み位置させる付帯部はパイプ部ＰＥに限定されるものではなく、挟持部ＣＥとの間への詰め部Ｔの挟み込みをもって、本体部ＭＥとの間の挟持間隔が拡大する側への挟持部ＣＥの弾性変位の剛性を高くし得る部分であれば、器体におけるいずれの部分を採用してもよい。
【００６１】
前述の実施形態では、骨伝導音声を検出する送信用素子１２と、受信用イヤホーン８との両方を本体部ＭＥに装備する例を示したが、これら送信用素子１２と受信用イヤホーン８とのいずれか一方のみを本体部ＭＥに装備するものであってもよい。

BACKGROUND OF THE INVENTION
The present invention relates to an ear-mounted sound information transmitter that is worn on a human ear.
[0002]
[Prior art]
Since this type of sound information transmitter is desired to be stably attached to the ear, as shown in FIG. 10, together with the main body ME inserted into the concha concavity Y, the ear shell is connected to the main body ME. A device that has a holding portion CE for holding the edge Yf of the cavity portion Y provided in the body and that is intended to be stably attached to the ear by this holding has been previously proposed (see Japanese Patent Application No. 8-107211).
[0003]
[Problems to be solved by the invention]
However, the attachment of the clamping part CE has improved the overall stability of wearing to the ear as a whole, but since the shape of the ear varies from person to person, the edge part Yf of the concha cavity part Y to be clamped is For thin people and people with large concha cavity Y and unstable insertion of the main body ME in general, there may be cases where clamping is insufficient and improvement in wearing stability cannot be achieved as expected. In this respect, there was still room for improvement.
[0004]
In contrast to the above circumstances, the main problem of the present invention is that, by adding a reasonable auxiliary tool, satisfactory wearing stability can be easily obtained even for a person who is insufficiently held only by the holding part. is there.
[0005]
[Means for Solving the Problems]
[1] In the first aspect of the present invention, the body includes a main body portion to be inserted into the concha cavity portion, and a holding portion for holding the edge portion of the concha cavity portion between the main body portion and the main body portion. On the other hand, a holding reinforcement tool is attached to the device body, and the abutment portion provided in the holding reinforcement device is positioned at a portion of the holding portion of the device body facing the edge of the concha cavity portion. Thus, with this abutment portion, the holding interval between the edge portion of the concha cavity portion and the main body portion is reduced, thereby strengthening the holding of the edge portion of the concha cavity portion.
[0006]
Therefore, a person who is insufficiently pinched only with the pinching portion can easily obtain strong mounting stability by simply tightening the edge portion of the concha cavity portion by simply mounting the pinning reinforcement tool on the body. On the other hand, for those who can obtain sufficient clamping with only the clamping part, it is possible to use the clamping reinforcement tool in a state where it is removed from the body without causing uncomfortable feeling due to excessive clamping. Satisfactory mounting stability can be obtained.
[0007]
[2] In the invention according to claim 2, the body includes a main body portion to be inserted into the concha cavity portion, an accessory portion extending from the main body portion and positioned outside the concha cavity portion, and a main body And an elastically displaceable clamping part that extends from the vicinity of the boundary between the head part and the accessory part and clamps the edge of the concha cavity part between the body part and the body part. And the stuffing portion provided in the sandwiching reinforcing tool is sandwiched between the sandwiching portion and the accessory portion of the body so that the sandwiching interval between the stuffing portion and the main body portion is increased. The rigidity of the elastic displacement of the pinching portion is increased, thereby strengthening the pinching of the edge of the concha cavity.
[0008]
Therefore, as in the first aspect of the invention described above, a person who is insufficiently pinched only by the pinching portion can simply hold the pinna with respect to the edge of the concha cavity portion by simply attaching the pinning reinforcement tool to the body. For those who can get strong and satisfactory wearing stability, and conversely, with only the clamping part, they can be clamped by using the clamping reinforcement tool while it is removed from the body. Satisfactory wearing stability can be obtained without causing discomfort due to being too strong.
[0009]
[3] In the invention according to claim 3, the body includes a main body portion to be inserted into the concha cavity portion, an accessory portion extending from the main body portion and positioned outside the concha cavity portion, and a main body. And an elastically displaceable clamping part that extends from the vicinity of the boundary between the head part and the accessory part and clamps the edge of the concha cavity part between the body part and the body part. The holding portion provided in the sandwiching reinforcing tool is positioned in a portion of the sandwiching portion of the body facing the edge of the concha cavity portion, and the filling portion provided in the sandwiching reinforcing tool is also provided. With the holding part and the stuffing part, the holding interval between the body part with respect to the edge part of the concha cavity part is reduced and the holding part is sandwiched between the holding part and the auxiliary part in the body. Increase the rigidity of the elastic displacement of the clamping part to the side where the interval is widened, and thereby, against the edge of the concha The clamping strongly.
[0010]
Therefore, as in the first and second aspects of the invention described above, a person who is insufficiently pinched only with the pinching portion can simply attach the pinning reinforcement tool to the body and simply attach to the body. For those who are able to obtain satisfactory mounting stability by strengthening the clamping to the edge of the part, and conversely, for those who can obtain sufficient clamping only with the clamping part, the state where this clamping reinforcement is removed from the body In this case, satisfactory mounting stability can be obtained without causing unpleasant feeling due to excessive clamping.
[0011]
Also, with the synergistic effect of reducing the holding interval between the main body and the rigidity of the elastic displacement of the holding portion toward the side where the holding interval is increased, Since the clamping is strengthened, a higher clamping strength can be obtained reliably and effectively than simply reducing the clamping interval or simply increasing the rigidity of the elastic displacement of the clamping part.
[0012]
[4] In the invention according to claim 4, in a state in which the stuffing portion in the sandwiching reinforcing tool is sandwiched between the sandwiching portion and the incidental portion in the body, the clamping portion is pressed by the stuffing portion and the concha cavity is pressed. Since the holding distance between the edge part of the body and the main body part is elastically displaced, when the holding reinforcing tool is attached, the holding distance is reduced and the holding distance is the basic function of the filling part as described above. With a synergistic effect of increasing the rigidity of the elastic displacement of the clamping part toward the side where the swell increases, a high clamping strength with respect to the edge part of the concha cavity part can be obtained reliably and effectively.
[0013]
[5] In the invention according to claim 5, since the fitting portion formed on the sandwiching reinforcement tool is fitted to the sandwiching portion of the container body in an external fitting state, the sandwiching reinforcement tool is attached to the container body. In other words, the holding reinforcing tool is attached to the container by fitting the fitting part of the holding reinforcing tool to the holding part of the container, and the holding reinforcing tool is removed from the container by removing the fitting. Since it removes, the attachment / detachment of the clamping reinforcement tool with respect to a container can be performed simply.
[0014]
[6] In the invention according to claim 6, since the fitting portion formed on the sandwiching reinforcing tool is fitted to the auxiliary portion of the container in an external fitting state, the sandwiching reinforcing tool is attached to the container. Similar to the fifth aspect of the invention described above, it is possible to easily attach and detach the holding reinforcing tool to the body.
[0015]
[7] In the invention according to claim 7, the first fitting portion formed on the sandwiching reinforcing tool is fitted to the sandwiching portion in an external fitting state, and the second fitting portion formed on the sandwiching reinforcing tool is attached to the auxiliary portion. The holding reinforcement tool is attached to the container body in an externally fitted state so that the holding reinforcement tool for the container body is similar to the invention of claim 5 and the invention of claim 6. It can be easily attached and detached. In addition, since the two reinforcing portions are fitted at two locations on the vessel body and the sandwiching reinforcing tool is attached, the holding reinforcement tool attached to the vessel body can be more reliably held.
[0016]
[8] In the invention according to claim 8, the center of gravity of the body including the sandwiching reinforcement is mounted in a state in which the sandwiching reinforcement is attached to the body and the main body portion of the body is inserted into the concha cavity. The body portion is sandwiched between the body portion and the pinching portion, with the edge portion of the concha cavity portion serving as a fulcrum, and the body portion is positioned at a position where gravity is biased inwardly of the concha cavity portion. The use of this body load, which also uses the load of the sandwiching reinforcement, can improve the mounting stability by urging the body part inward of the concha cavity, and the abutment and stuffing part of the sandwiching reinforcement can be used as described above. In combination with strengthening the clamping of the edge of the concha cavity, it is possible to more effectively enhance the wearing stability for a person who is insufficient only with the clamping part.
[0017]
In carrying out each of the above inventions, the following a. ~ G. It is preferable to selectively adopt the configuration.
[0018]
A. The said abutting part is formed with an elastic material. That is, according to this configuration, the abutment portion can be well fitted to the edge of the concha cavity portion with the elasticity of the abutment portion, thereby improving the wearing stability and improving the wearing sensation. Can be improved. In addition, while the clamping is strengthened by reducing the clamping interval by the abutting portion, the application range of the clamping reinforcement for various ear shapes can be widened by the flexibility obtained by the elasticity of the abutting portion.
[0019]
B. The contact surface of the abutting portion with respect to the edge portion of the concha cavity portion is formed as a curved surface in which the upper and lower intermediate portions bulge toward the edge portion of the concha cavity portion. That is, according to this configuration, the abutment part is brought into contact with the edge part of the concha cavity part in such a manner that the bulging curved surface of the abutment part enters the hollow part on the outer surface side at the edge part of the concha cavity part. Thus, the edge portion of the concha cavity portion can be clamped, and this can improve the wearing stability.
[0020]
C. The padding portion in the sandwiching reinforcing tool is formed of an elastic material. That is, according to this configuration, as a basic function of the stuffing portion, the rigidity of the clamping portion is increased by increasing the rigidity of the elastic displacement of the clamping portion toward the side where the clamping interval is widened, and the holding portion is elastic. In a state where the elastic displacement function is left, a good wearing feeling can be obtained by making the holding portion elastically contact the edge portion of the concha cavity portion even when the holding reinforcement tool is mounted. In addition, the application range of the sandwiching reinforcing tool for various ear shapes can be widened by the versatility obtained by leaving the elastic displacement function of the sandwiching portion.
[0021]
D. Forming the stuffing portion in the sandwiching reinforcing tool into a wedge shape, and inserting the stuffing portion between the sandwiching portion and the accessory portion in the body with the wedge-shaped tip side first, It shall be configured to be attached.
[0022]
In other words, according to this configuration, the wedge portion has a wedge effect, and it is easy to insert the stuffing portion between the sandwiching portion and the accompanying portion, and the stuffing portion is accurately sandwiched between the sandwiching portion and the accompanying portion. Therefore, the expected function of the filling portion as described above can be surely exhibited.
[0023]
E. With the pipe part through which the cable extending from the main body part is inserted as the above-mentioned accessory part, the stuffing part of the sandwiching reinforcement tool is sandwiched between the pipe part and the sandwiching part when the sandwiching reinforcement tool is attached to the body. Position.
[0024]
That is, in the body, the pipe part is configured to extend downward from the outer ear end part of the main body part to be inserted into the concha cavity part to the outside of the concha cavity part. The holding portion that holds the edge portion of the cavity portion between the body portion and the body portion is in a positional relationship adjacent to the pole portion. Therefore, as described above, the pipe portion is used as an auxiliary portion, and the pipe portion and the holding portion are interposed. With the configuration in which the stuffing portion of the sandwiching reinforcing tool is sandwiched and positioned, the size required for the stuffing portion itself can be reduced and the sandwiching reinforcing tool can be made compact.
[0025]
In addition, regarding a configuration in which the fitting portion formed on the sandwiching reinforcement tool is fitted to the accessory portion and the sandwiching reinforcement tool is attached to the body, the pipe portion is used as the accessory portion, and the sandwiching reinforcement tool is attached to the pipe portion. When the fitting part is fitted, the pipe part and the clamping part are adjacent to each other in the vicinity of the pole as described above. Thus, the sandwiching reinforcing tool can be more effectively downsized.
[0026]
F. A transmitting element for detecting bone conduction sound transmitted to the cartilage of the ear is provided in the main body. That is, according to this configuration, the user's own bone conduction sound can be detected, converted into an electrical signal, and transmitted to a necessary place.
[0027]
And in this mode of use, if the holding reinforcement is attached to the body, the body portion is strengthened with respect to the edge of the concha cavity even for a person who is insufficiently held only by the holding portion of the body. By increasing the contact pressure between the ear and the concha cavity, it is possible to detect the bone conduction sound propagating as a minute vibration on the surface of the concha cavity with high sensitivity, and to improve the bone conduction sound. It can be sent.
[0028]
Further, if carried out in parallel with the above-mentioned invention according to claim 8, gravity biasing of the main body part toward the inward direction of the concha cavity part causes contact pressure between the main body part and the concha cavity part. Therefore, the detection sensitivity of the bone conduction voice can be improved more effectively.
[0029]
G. A receiving earphone is mounted on the main body. That is, according to this configuration, it is possible to listen to sound information such as sound transmitted as an electrical signal by emitting sound from the earphone.
[0030]
And in this form of use, if the holding reinforcement is attached to the body, even a person who is insufficiently held only by the holding part of the body can obtain a high wearing stability, so that a good listening state can be stabilized. Can be maintained.
[0031]
Also, as described above. If this configuration is implemented in parallel, transmission and reception can be performed simply by inserting the main body into the concha cavity, and a very compact telephone can be realized when used for calls between people. it can.
[0032]

The body includes a main body ME to be attached to the concha cavity Y of the ear shown by hatching in FIG. 12, and a main body ME as an accessory. An electric wire insertion pipe portion PE extending downward from the outer ear end portion and positioned outside the concha cavity Y, and downward from the vicinity of the boundary between the main body ME and the pipe portion PE in a tongue-like shape As shown in FIG. 10, in addition to inserting the main body ME into the concha cavity Y, as shown in FIG. 10, the main body ME and the clamping portion CE are provided. Thus, the edge Yf of the concha cavity Y is sandwiched between these two parts ME and CE, thereby improving the stability of wearing on the ear.
[0033]
In addition, the edge part Yf of the concha cavity part Y is an extension part which exists in the connection part of the tragus 50 and the antipod 51, as shown in FIG.10 and FIG.11.
[0034]
The main body ME has a bifurcated structure in which the first and second housings 1 and 6 that are vertically spaced apart from each other are connected to the support member 2 at the outer ear end, and the first and second housings 1 and 6 are By receiving and supporting the receiving earphone 8 in the second housing 6 on the upper side, an earphone unit RE that converts a voice signal from the other party to voice and outputs it to the ear canal 53 is configured. A protector 4 is attached to the inner ear opening of the second housing 6 so as to cover the front surface of the receiving earphone 8.
[0035]
In configuring the earphone unit RE, the second housing 6 is formed of a metal having a large specific gravity such as brass so as to function as a damping means VA for attenuating fine vibration transmitted from the receiving earphone 8. Furthermore, the second housing 6 is attached to the support member 2 via the damping member 3 made of a viscoelastic body based on a plastic material so as to suppress the propagation of micro vibrations from the second housing 6 to the support member 2. It is connected.
[0036]
On the other hand, as shown in FIGS. 5 and 8, the first housing 1 in the main body ME has a large-diameter portion 1a positioned on the inner side of the concha cavity portion Y, and a support member from the large-diameter portion 1a. The small-diameter portion 1b is formed in two, and the piezoelectric element 12 for detecting bone conduction voice is internally supported in the large-diameter portion 1a as a transmitting element, and the substrate 10 on which the field effect transistor 13 is mounted is supported by the small-diameter portion 1b. The bone conduction voice pickup unit SE for detecting bone conduction voice transmitted to the human ear (sound vibration transmitted from the vocal cords to the ear part due to bone conduction as the voice utters) is provided.
[0037]
The piezoelectric element 12 oscillates along with the vibration of the bone conduction sound transmitted from the surface of the concha cavity Y to the first housing 1 (particularly the large diameter portion 1a) and detects the bone conduction sound by the piezoelectric effect. A large-diameter portion 1a is housed in a cantilevered state in which only one end in the longitudinal direction is fixedly supported, and is electrically connected to the circuit of the substrate 10 by a cable 16. A metal plate serving as an electrode is attached to the piezoelectric element 12. A bimorph type piezoelectric ceramic element in which two piezoelectric ceramic materials are sandwiched and sandwiched is used to reduce the size and improve the detection sensitivity for bone conduction sound which is weak vibration.
[0038]
Further, by covering the entire piezoelectric element 12 with a shield case 15, the S / N ratio (signal noise ratio) is improved, and by covering the shield case 15 with the first housing 1, protection against an external injury factor is provided. It is illustrated.
[0039]
Of the large-diameter portion 1 a of the first housing 1, the abutment surface portion with respect to the bottom surface B of the concha cavity portion Y secures a large contact area with the bottom surface B of the concha cavity portion Y as much as possible. The first housing 1 is relatively moisturizing such as ABC resin or vinyl chloride resin, and is formed in an arcuate curved shape that bulges to the bottom surface B side of the concha cavity Y. In addition to being formed of a high material, the surface is polished to a mirror finish to improve the adhesion and familiarity with the skin.
[0040]
FIG. 9 shows a circuit configuration, in which the output voltage of the piezoelectric element 12 as a bone conduction audio signal is impedance-converted and amplified by the field effect transistor 13 and then output to the transmission cable 7, and also via the reception cable 9. The voice signal input from the other party is converted into a voice signal by the receiving earphone 8.
[0041]
The transmission cable 7 and the reception cable 9 have a common line. As shown in FIGS. 5 and 7, the reception cable 9 extends from the reception earphone 8 to the wiring insertion hole 3 a of the attenuation member 3 and the support member 2. The transmission cable 7 is inserted into the pipe portion PE via the wiring insertion hole (not shown) formed in the support member 2 and connected to the plug 14 through the pipe portion PE through the wiring insertion hole 2a. 14 and the plug 14 is used to connect the transmission / reception cables 7 and 9 to a communication device such as a mobile phone or a transceiver.
[0042]
In other words, with the above configuration, when a user wearing this telephone on the ear utters, the vocal cord vibration at the time of the utterance is transmitted to the ear as bone conduction sound via the jaw or the skull, and the bone conduction voice pickup unit It is detected by the piezoelectric element 12 in SE, and is converted into an electric signal corresponding to the sound vibration by the piezoelectric element 12 and transmitted to the other party of the call by the call device connected with the plug 14.
[0043]
Also, a voice signal from the other party is input to the receiving earphone 8 of the earphone unit RE from the calling device connected to the plug 14, and then converted into a voice by the earphone 8 and output to the ear canal 53 to be applied to the eardrum. Reach. That is, by making a call using this telephone, it is possible to make a call with little influence of external noise on both transmission and reception.
[0044]
The tongue-shaped pinching portion CE that holds the edge Yf of the concha cavity portion Y with the main body ME is formed of an elastic material such as rubber or vinyl chloride having a hardness of 50 to 80, and is in a bent form. Elastic displacement is possible, and thereby a good wearing sensation is obtained by elastic contact with the edge Yf of the concha cavity Y while ensuring clamping of the concha cavity Y with respect to the edge Yf. In addition, it is possible to ensure a wide range of correspondence that can be appropriately held with respect to various ear shapes.
[0045]
Further, in this communication device, a person with a thin edge Yf of the concha cavity Y or a person with a large concha cavity Y and an unstable insertion of the main body ME itself, In the case where the clamping is loose and the mounting is unstable, as shown in FIGS. 1 to 4, by attaching a detachable clamping reinforcement tool H to the body, the clamping to the edge Yf of the concha cavity Y is strengthened. And satisfactory mounting stability.
[0046]
As shown in FIG. 2, the sandwiching and reinforcing tool H has a bifurcated cylindrical shape, and is formed of an elastic material such as rubber, vinyl chloride, or sponge. One of the bifurcated cylinders has a first cylindrical portion h1. The first fitting part is fitted to the clamping part CE in the outer fitting state, and the other second cylindrical part h2 is fitted to the pipe part PE as the second fitting part in the outer fitting state. Mounting.
[0047]
Then, the laterally outer portion of the first cylindrical portion h1 is used as a holding portion A for reducing the holding interval, and the putting portion A is attached to the body while the holding portion A is the edge Yf of the concha cavity portion Y of the holding portion CE. Is positioned on the surface portion opposite to the body portion ME with respect to the edge portion Yf of the concha cavity portion Y, and the space between the first and second tube portions h1 and h2 is reduced. The crotch portion is used as a stuffing portion T for increasing rigidity, and the stuffing portion T is sandwiched between the sandwiching portion CE and the pipe portion PE in a state where the crotch portion is attached to the body. The rigidity of the elastic displacement of the clamping part CE toward the side where the interval is increased is increased, and the clamping of the edge portion Yf of the concha cavity part Y is strengthened by reducing the clamping interval and increasing the rigidity.
[0048]
The contact surface of the abutting part A with respect to the edge Yf of the concha cavity Y is formed as a curved surface in which the upper and lower intermediate parts bulge toward the edge Yf of the concha cavity Y. The abutment A is brought into contact with the edge of the concha cavity Y in such a manner that the bulging curved surface of the abutment A enters the hollow portion on the outer surface side at the edge Yf of the concha cavity Y. By sandwiching the edge Yf of the cavity Y, the mounting stability is further improved.
[0049]
On the other hand, the stuffing portion T is formed in a wedge shape. When the sandwiching portion CE and the pipe portion PE are inserted into the respective cylindrical hole portions of the bifurcated cylinder and the sandwiching reinforcing tool H is attached to the body, the wedge-shaped tip end is formed. By adopting a configuration in which the stuffing portion T is inserted between the sandwiching portion CE and the pipe portion PE with the side first, due to the wedge effect generated at this time, the stuffing portion T between the sandwiching portion CE and the pipe portion PE While making the insertion easy, the filling portion T can be accurately pinched between the pinching portion CE and the pipe portion PE.
[0050]
Further, by forming the entire sandwiching reinforcing tool H from an elastic material and providing the abutting part A and the stuffing part T with elasticity, the mounting stability is further improved, and also when the sandwiching reinforcing tool H is used. Further, in order to maintain a good wearing feeling, it is possible to ensure a wide range of application of the sandwiching reinforcement H to various ear shapes by the flexibility obtained with elasticity.
[0051]
In constructing a container including the main body ME, the pipe portion PE, and the sandwiching portion CE, as described above, the second housing 6 is formed of a metal material having a large specific gravity. 10, in the state where the main body ME is mounted on the concha cavity Y, the center of gravity of the body is centered on the edge Yf of the concha cavity Y held between the main body ME and the clamping CE. In other words, the body center of gravity is located in the ear rather than the outer edge of the edge Yf of the concha cavity Y so that the main body ME is located at a position where gravity is biased inwardly of the concha cavity Y. Similarly, when the body part ME is attached to the concha cavity part Y with the sandwiching reinforcing tool H attached to the body as shown in FIG. The concha cavity Y where the center of gravity of the body including the reinforcing tool H is clamped between the main body ME and the clamping part CE It is so as to be kept a body portion ME at positions gravity biased inwardly facing concha Y edges Yf as a fulcrum.
[0052]
In other words, this urging force, coupled with the clamping by the clamping part CE, and also with the increased clamping strength by using the clamping reinforcement tool H, can further increase the wearing stability, and further, the concha The contact pressure between the bottom surface B of the part Y and the bone conduction voice pickup part SE is increased to increase the detection sensitivity of the bone conduction voice.
[0053]
In addition, a small hole as a weight mounting part WS is formed at the lower end of the clamping part CE. If necessary, a weight WT having an appropriate weight is suspended in the small hole WS, thereby allowing the concha cavity part to be suspended. The contact surface pressure between the bottom surface B of Y and the bone conduction sound pickup unit SE can be further increased. Moreover, the weight WT can be used in various shapes, and may be appropriately exchanged according to the user's preference for use in improving fashionability. This weight WT, like the above-described sandwiching reinforcement tool H, may be attached only when necessary, and removed when unnecessary.
[0054]
[Another embodiment]
Next, another embodiment of the invention will be listed.
The specific shape and structure of the sandwiching reinforcing tool H can be changed in various configurations. For example, as shown in FIGS. 13 and 14, the tube part h2 is fitted into the pipe part PE in an externally fitted state. In the single cylinder structure, one side portion of the cylinder portion h2 is used as a stuffing portion T for increasing rigidity, and the stuffing portion T is attached to the vessel body. It is good also as what is made to pinch between the clamping part CE and the pipe part PE.
[0055]
Further, the stuffing portion T is sandwiched between the sandwiching portion CE and the pipe portion PE to increase the rigidity of the elastic displacement of the sandwiching portion CE toward the side where the sandwiching interval with the main body ME is increased. In addition, as shown in FIG. 14, in a state where the stuffing portion T is sandwiched between the sandwiching portion CE and the pipe portion PE, the sandwiching portion CE is sandwiched between the main body ME by pressing by the stuffing portion T. You may make it elastically displace to the side where a space | interval becomes small.
[0056]
As shown in FIG. 15 and FIG. 16, the tube portion h1 is fitted as a fitting portion into the holding portion CE in an externally fitted state so as to be attached to the body, and in the single tube structure, the tube portion One side portion of h1 is used as a holding portion A for reducing the holding interval, and the holding portion A is attached to the surface portion of the holding portion CE that faces the edge Yf of the concha cavity portion Y in the mounted state. Positioned and the other side portion of the cylindrical portion h1 is used as a stuffing portion T for increasing rigidity, and the stuffing portion T is sandwiched between the sandwiching portion CE and the pipe portion PE in a state of being attached to the body. It is good.
[0057]
The sandwiching reinforcing tool H may be either provided with only one of the abutting part A and the stuffing part T, or may be provided with both the abutting part A and the stuffing part T. The structure and shape, and the detailed structure and shape of the abutting portion A and the filling portion T can be variously changed.
[0058]
The mounting structure of the sandwiching reinforcement H to the body is not limited to the above-mentioned external fitting state, and various configurations can be changed, and it is attached to the body using an appropriate connector that can be easily attached and detached. You may employ | adopt the structure to do.
[0059]
In the above-described embodiment, in order to make the clamping part CE elastically displaceable, the clamping part CE itself is formed of an elastic material and is elastically displaced. However, the clamping part CE has an appropriate elastic biasing means such as a spring. May be supported so as to be elastically displaceable.
[0060]
In the above-described embodiment, the example in which the stuffing portion T of the sandwiching reinforcement tool H is sandwiched between the sandwiching portion CE and the pipe portion PE has been described. The incidental part where the T is sandwiched is not limited to the pipe part PE, but is sandwiched on the side where the sandwiching interval with the main body ME is expanded by sandwiching the stuffing part T with the sandwiching part CE. As long as the rigidity of the elastic displacement of the part CE can be increased, any part in the vessel may be adopted.
[0061]
