Summary:To surely notify the surroundings that a call is being made with a simple configuration at least when a received voice is listened to with an external audio device such as earphones.SOLUTION: A control unit 111 of a telephone body 1 controls an oscillator 108 during a call, generates a high-frequency signal, superimposes the signal on a received voice signal through a HPF 109, and outputs the signal from a voice input/output terminal unit 106. The received voice signal on which the high-frequency signal from the telephone body 1 is superimposed is received through a voice input/output terminal 201 of an earphone unit 2 and supplied to a rectifier circuit 206 through the HPF 205. In the rectifier circuit 206, a DC drive signal is formed from the high frequency signal supplied to the rectifier circuit 206, and supplied to the LEDs 207L and 207R to light the LEDs 207L and 207R.SELECTED DRAWING: Figure 1 【課題】 少なくとも受話音声をイヤホンなどの外部音響機器で聴取する場合において、簡単な構成で、かつ、確実に通話中であることを周囲に報知できるようにする。【解決手段】電話本体部１の制御部１１１が通話時において発振器１０８を制御し、高周波信号を発生させて、ＨＰＦ１０９を通じて受話音声信号に重畳し、これを音声入出力端子部１０６から出力する。電話本体部１からの高周波信号が重畳された受話音声信号は、イヤホン部２の音声入出力端子部２０１を通じて受け付けられ、ＨＰＦ２０５を通じて整流回路２０６に供給される。整流回路２０６においては、これに供給された高周波信号から直流駆動信号が形成され、これがＬＥＤ２０７Ｌ、２０７Ｒに供給されて、ＬＥＤ２０７Ｌ、２０７Ｒが点灯される。【選択図】図１
