ハンドセツト装置。[Scope of Claim for Utility Model Registration] A first microphone and a second earpiece are built into a storage section on one side of the handset, and
Comparing the level of the input signal from the first microphone and the level of the input signal from the second microphone in a telephone in which a second microphone and a first earpiece are built into the housing on the other side. and a level discrimination circuit that outputs a control signal based on the comparison result. Based on the control signal from this level discrimination circuit,
When the input signal level from the first microphone is higher than the input signal level from the second microphone, the second microphone and the second earpiece are muted, and the input signal from the first microphone is muted. A telephone handset device comprising: a mute circuit that mutes the first microphone and the first earpiece when the signal level is lower than the input signal level from the second microphone.
