A hand-free (HF) amplifier 110, a changeover switch 112, and a changeover switch 113 are included.
The telephone body 2 includes an interface (IF) 201.

  Interfaces 111 and 201 connect the telephone body 2 and the handset 1. When the contact sensor 104 and the human proximity sensor 106 are in the ON state, the handset call mode is determined. The VR 105 adjusts the volume of the speaker in the hands-free call mode. The HF setting switch 114 switches to the hands-free call mode. The HF / HS switching control unit 103 switches between a hands-free call mode and a handset call mode.

  The HS amplifier 107 is an amplifier for the speaker 101 in the handset call mode. The HF amplifier 108 is an amplifier for the speaker 101 in the hands-free call mode. The HS amplifier 109 is an amplifier of the microphone 102 at the time of handset. The HF amplifier 110 is an amplifier of the microphone 102 when hands are free.

  The changeover switch 112 switches between the hands-free call mode and the handset call mode of the speaker 101. The change-over switch 113 switches between the hands-free call mode and the handset call mode of the microphone 102.

  The contact sensor 104 is a mechanical switch, and when it is off-hook, it detects ON when it contacts the vicinity of the ear. The contact sensor 104 is ON even when on-hook, but is invalid. The human proximity sensor 105 is specifically an infrared sensor, and is turned on by detecting infrared light from the head.
