The present invention relates to a vehicle air conditioner, and the objective of the present invention is to improve a microphone mounting structure of a noise reduction device such that a microphone can acquire the air-conditioning noise of an air-conditioning case without direct contact with the air of an inner path of the air-conditioning case, thereby preventing contamination of and damage to the microphone, caused by direct contact between the air of the inner path of the air-conditioning case and the microphone, and the generation of unnecessary blowing noise. In order to accomplish the objective, the present invention relates to the vehicle air conditioner including the noise reduction device capable of reducing the air-conditioning noise, wherein the noise reduction device comprises: the microphone capable of acquiring the air-conditioning noise of the inner path of the air-conditioning case; and a speaker outputting a noise-damping sound wave to the inner path of the air-conditioning case on the basis of the air-conditioning noise acquired by the microphone, so as to reduce the air-conditioning noise, and has a microphone mounting part for mounting the microphone at one side surface portion of the air-conditioning case so as to enable acquisition of the internal air-conditioning noise of the air-conditioning case on the outside of the air-conditioning case. La présente invention concerne un climatiseur de véhicule, et l'objectif de la présente invention est d'améliorer une structure de montage de microphone d'un dispositif de réduction de bruit de sorte qu'un microphone peut acquérir le bruit de climatisation d'un boîtier de climatisation sans contact direct avec l'air d'un trajet interne du boîtier de climatisation, empêchant ainsi la contamination et l'endommagement du microphone, provoqués par un contact direct entre l'air du trajet interne du boîtier de climatisation et le microphone, et la génération de bruit de soufflage inutile. Afin d'atteindre l'objectif, la présente invention concerne un climatiseur de véhicule incluant le dispositif de réduction de bruit capable de réduire le bruit de climatisation, le dispositif de réduction de bruit comprenant : le microphone capable d'acquérir le bruit de climatisation du trajet interne du boîtier de climatisation ; et un haut-parleur émettant une onde sonore d'amortissement de bruit vers le trajet interne du boîtier de climatisation sur la base du bruit de climatisation acquis par le microphone, de manière à réduire le bruit de climatisation, et présente une partie de montage de microphone permettant de monter le microphone au niveau d'une partie de surface latérale du boîtier de climatisation de manière à permettre l'acquisition du bruit de climatisation interne du boîtier de climatisation sur l'extérieur du boîtier de climatisation. 본 발명은 차량용 공조장치에 관한 것으로서, 소음저감장치의 마이크 장착구조를 개선함으로써, 공조케이스의 내부유로측 공기와의 직접적인 접촉없이도 마이크가 공조케이스측의 공조소음을 획득할 수 있고, 이를 통해, 공조케이스의 내부유로측 공기와 마이크의 직접적인 접촉으로 인한 마이크의 오염과 손상 및, 불필요한 송풍소음 발생을 방지할 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 공조 소음을 저감시킬 수 있는 소음저감장치를 포함하며, 소음저감장치는 공조케이스의 내부유로측 공조 소음을 획득할 수 있는 마이크와, 마이크에서 획득한 공조 소음을 근거로 공조케이스의 내부유로에 소음 감쇄 음파를 출력하여 공조소음을 저감시키는 스피커를 포함하는 차량용 공조장치에 있어서, 공조케이스의 외측에서 공조케이스의 내부 공조소음을 획득할 수 있도록, 마이크를 공조케이스의 일측면부분에 장착하는 마이크 장착부를 구비한다.
