摘要:
A voice input-output device includes a voice input section and a voice output section. The voice input section includes a microphone unit, the microphone unit including a housing that has an inner space, a partition member that is provided in the housing and divides the inner space into a first space and a second space, the partition member being at least partially formed of a diaphragm, and an electrical signal output circuit that outputs an electrical signal that is the first voice signal based on vibrations of the diaphragm, a first through-hole through which the first space communicates with an outer space of the housing and a second through-hole through which the second space communicates with the outer space being formed in the housing. The voice output section includes: an ambient noise detection section that detects ambient noise during a call based on the first voice signal; and a volume control section that controls volume of the speaker based on a degree of the detected ambient noise.
