    摘要： A microphone unit (1) is disposed in the inside of a first housing (51) of a voice input apparatus. The microphone unit (1) includes: a second housing (11); a diaphragm (122) which is disposed in the inside of the second housing (11); and an electric circuit portion (12, 13, 14) which processes an electric signal that is generated based on a vibration of the diaphragm (122). In the voice input apparatus, a first sound guide space (513) which guides a sound outside the first housing (51) to a first surface (122a) of the diaphragm (122) and a second sound guide space (514) which guides a sound outside the first housing (51) to a second surface (122b) of the diaphragm (122) are formed. The electric circuit portion (12, 13, 14) is disposed in either one of the first sound guide space (513) and the second sound guide space (514); and an acoustic resistance portion (52) which adjusts at least one of a frequency characteristic of the first sound guide space (513) and a frequency characteristic of the second sound guide space (514) is formed.

    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.
