The invention provides a vehicle seat capable of actively reducing noise. The vehicle seat comprises a main body, a back cushion and an extension groove, wherein the back cushion is embedded in the top end of the main body, and an opening of the extension groove is formed in the inner middle part of the main body; the main body comprises a base and a backrest; the back cushion comprises earmuffs and sliding grooves; each sliding groove comprises a limiting groove, an embedding groove and a limiting groove; the extension groove comprises an extension plate, a displacement rod and a bundling groove; the expansion plate comprises an expansion rod and an expansion block; and the displacement rod comprises a displacement shaft, a sleeving groove, a sleeving ring and a limiting shaft. The vehicle seat is provided with the extension groove, and the displacement rod in the extension groove can make the earmuffs on the two sides of the back cushion deflect towards the center of the front end when moving under pushing by pressure, so the earmuffs can conduct sound insulation on ears when needed so as to reduce noise.
本发明提供了一种主动降噪的车用座椅,包括主体、靠枕和延伸槽,主体顶端嵌入设置有靠枕,延伸槽开口设置于主体内部中部;主体包括有底座和靠背,靠枕包括有耳罩和滑槽,滑槽包括有限定槽、嵌合槽和限位槽,延伸槽包括有扩展板、位移杆和收束槽,扩展板包括有扩展杆和扩展块,位移杆包括有位移轴、套接槽、套接环和限位轴,该装置设置有延伸槽,通过延伸槽内部的位移杆在被施压推动进行移动的时候能够将靠枕两侧的耳罩向前端的中心处进行偏斜移动,使得其能够在需要的时候将耳部进隔音减少其噪音。
