To provide a microphone/speaker integrated device capable of increasing sensitivity of a microphone to sounds to be collected.SOLUTION: A microphone/speaker integrated device includes: two microphones 11, 13 forming directivity; a speaker 12 arranged between the two microphones 11, 13; a driver seat determination part for determining a driver seat of a vehicle that is equipped with the microphone/speaker integrated device; and a directivity adjustment part for adjusting the direction of directivity showing a direction where the sensitivity of the two microphones 11, 13 is increased. The directivity adjustment part adjusts the direction of the directivity of each of the two microphones 11, 13 to a direction of the driver seat, when a use mode of the two microphones 11, 13 is a voice recognition mode, while, when a use mode of the two microphones 11, 13 is an emergency call mode, adjusts the directions of the directivity of the two microphones 11, 13 to a direction of the driver seat and a direction of a front passenger seat, respectively.SELECTED DRAWING: Figure 1
【課題】収集対象の音声に対するマイクの感度を高めることができるマイク・スピーカ一体装置を提供する。【解決手段】指向性を形成する二つのマイク11、13と、二つのマイク11、13の間に配置されるスピーカ12と、自装置を装備する車両の運転席を判別する運転席判別部と、二つのマイク11、13の感度が高くなる方向を示す指向性の向きを調整する指向性調整部と、を備え、指向性調整部は、二つのマイク11、13の使用モードが音声認識モードである場合に、二つのマイク11、13の指向性の向きをそれぞれ運転席の方向に調整し、二つのマイク11、13の使用モードが緊急通報モードである場合に、二つのマイク11、13の指向性の向きをそれぞれ運転席の方向及び助手席の方向に調整する。【選択図】図1
