400 補聴器プロセッサ
Claims (1)
- 移動通信端末(100)のマイクロホンに入力された音波を、使用者の難聴帯域別に補償増幅して、近距離通信チャンネルで提供する折り畳み式イヤーセット及びハウリング防止回路を備えたモバイル補聴器において、
帽子(200)に取り付けられた折り畳み式イヤーセット及びハウリング防止回路を備えたモバイル補聴器として、
帽子(200)の内周縁には、プラスチックや金属で構成される支持部材(210)を配置し、
前記支持部材(210)の一側には、左チャンネルイヤーセット(300L)と、
前記左チャンネルイヤーセット(300L)に固定され、上下方向に回動する左ヒンジ部(310L)と、
前記左ヒンジ部(310L)を支持部材(210)に固定させる左ヒンジ固定部(320L)と、
前記左チャンネルイヤーセット(300L)が耳を覆う対向面に配置される、人体赤外線を感知する左チャンネル人体赤外線センサ(SL)と、を備え、
前記支持部材(210)の他側には、
右チャンネルイヤーセット(300R)と、
前記右チャンネルイヤーセット(300R)に固定され、上下方向に回動する右ヒンジ部(310R)と、
前記右ヒンジ部(310R)を支持部材(210)に固定させる右ヒンジ固定部320Rと、
前記右チャンネルイヤーセット(300R)が耳を覆う対向面に配置される、人体赤外線を感知する右チャンネル人体赤外線センサ(SR)と、で構成され、
前記支持部材(210)の前面中央には、
補聴器プロセッサ(400)が、帽子(200)の内部または外部に固定配置され、
前記補聴器プロセッサ400の右チャネルと左チャネルの回路が同一に構成され、
Rイヤーピース増幅部(412R)は、L/R分離D/A変換部(410)の右チャンネルの信号を提供され、R2/R1の増幅度を有する非反転増幅器A1と、前記A1の出力を入力として、-R4/R3の増幅度を有する反転増幅器A2との2つの増幅器であって、右チャンネルイヤーセットユニット(302R)が差動で駆動され、
A1の反転入力とA2の非反転入力は、VccとGNDの中点電位Vcc/2で提供され、Rミューティング部(414R)のRbとバイアス回路によってオフセットやドリフトの影響を最小化し、
比較器Saの出力が「0」(GND)となると、A1の反転入力とA2の非反転入力の中点電位を「0」に制御し、これに基づき、A1とA2の出力は、GNDとなるので、L/R分離D/A変換部(410)から提供される右チャンネルの信号がミューティングされるように構成され、
前記比較器Saの非反転入力は、Vcc-GND間のRrに分圧された電圧が印加され、反転入力は、抵抗Rsと右チャンネル人体赤外線センサ(SR)の直列連結によって、人体赤外線が感知されると、Saの出力は、GNDとなり、右チャンネルイヤーセットユニット(302R)に供給される信号がミューティングされるように構成された
ことを特徴とする折り畳み式イヤーセット及びハウリング防止回路を備えたモバイル補聴器。
