Description
(第1の実施形態)
図1は、本発明の第1の実施形態に係る電子機器1の要部の機能ブロックを示す図である。電子機器1は、例えば通話機能を有する2つの筺体が互いに重畳する面積が多い閉状態と、重畳する面積が少ないかあるいはゼロとなる開状態とに変異可能な開閉可能な携帯電話である。例えば折畳タイプ、スライドタイプ等がある。
このような携帯電話は、無線通信部5と、マイク7と、パネル10と、表示部20と、圧電素子30と、入力部40と、制御部50と、開閉検出部100を備える。無線通信部5は、公知の構成からなり、基地局等を介して通信ネットワークに無線接続される。マイク7は、コンデンサマイク等の公知のマイクからなり、無線通信部5を介しての通話時に利用者が発する送話音等を集音する。
(第2の実施形態)
本発明の第2の実施形態に係る電子機器は、第1の実施形態に係る電子機器1の構成において、サイドトーンの位相を、周囲の騒音を弱める逆位相とする。そのため、制御部50は、無線通信部5による通話中にサイドトーン処理を実行する。
(第3の実施形態)
本発明の第3の実施形態に係る電子機器は、第1の実施形態に係る電子機器1の構成において、パネル10への利用者の耳(接触物)の接触面積に応じてサイドトーンのレベルを調整する。そのため、制御部50は、パネル10への接触物の接触面積検出機能を有し、無線通信部5による通話中に、接触面積検出機能により検出されるパネル10への接触物の接触面積に基づいて、サイドトーンの割り込み処理を実行する。
(第4の実施形態)
本発明の第4の実施形態に係る電子機器は、スピーカ機能を実行させて通話しているときにサイドトーン機能を実行していた場合における終話時のハウリングの発生を低減するものである。携帯電話は、通常、終話したい場合に終話キーを押下するが、例えば終話キーを操作せずに、開状態から閉状態への移行(あるいは閉状態の検出)をもって、終話キーの操作とみなすことで、終話ができる機能がある。このような機能を設定している場合、携帯電話を閉じたという信号FOLDER DET信号(FOLDER DET=0)を受けた際、その信号が連続して2回以上受けた場合にはじめて通話を終了する。これは1回だけの検出による誤検出低減のためである。
