The air conditioner air inlet silencing structure comprises an air conditioner box shell assembly, an air inlet is formed in the side portion of the air conditioner box shell assembly, a sound insulation cover is installed at the position, corresponding to the air inlet, of the air conditioner box shell assembly, the upper side of the sound insulation cover is open, and the lower side of the sound insulation cover is open. Therefore, airflow can be introduced into the air inlet from top to bottom. The air conditioner box has the beneficial effects that after the air conditioner box is installed inside an automobile instrument desk, the sound insulation cover can change the air inlet direction of airflow, the airflow is led into the air inlet from top to bottom, it is guaranteed that a wind noise field generated when the airflow enters the air inlet does not face the direction of a main driver and a co-driver, the purpose of active noise reduction is achieved, and therefore the NVH performance of an air condit
