The noise reduction equipment for the marine air conditioner comprises a supporting frame, side walls are connected to the two sides of the supporting frame, sealing plates are connected to the top end and the bottom end of the supporting frame correspondingly, and noise reduction mechanisms are connected to the surfaces of the sides, close to each other, of the side walls; the noise reduction mechanism comprises a plurality of telescopic sound absorption columns connected to the surfaces of the sides, close to each other, of the side walls, and sound wave noise reduction assemblies connected with the telescopic sound absorption columns. The top ends of the inner side surfaces of the side walls are connected with extrusion assemblies, and the extrusion assemblies are connected with the adjacent telescopic sound absorption columns. The noise reduction sound wave is played through the loudspeaker connected with the noise collecting device, noise generated by the air conditioner element is offset, the position of the sound wave noise reduction assembly can be adjusted at will, and therefore the sound wave noise reduction assembly can be close to the air conditioner element generating noise to conduct noise reduction.
本发明提供了一种船用空调的降噪设备,包括支撑框,所述支撑框的两侧连接有侧壁,所述支撑框的顶端和底端均连接有封板,所述侧壁相互靠近的一侧表面连接有降噪机构;所述降噪机构包括连接于侧壁相互靠近的一侧表面的多个伸缩吸音柱,以及与伸缩吸音柱相连接的声波降噪组件;所述侧壁内侧表面的顶端连接有挤压组件,所述挤压组件与相邻伸缩吸音柱相连接。本发明通过与噪声采集装置相连接的扬声器播放该降噪声波,抵消空调元件所产生的噪音,并使得可以任意调整声波降噪组件的位置,以便于声波降噪组件靠近产生噪音的空调元件进行降噪。
