Active noise reduction and sound suppression device for indoor low-frequency noise
The invention discloses an active noise reduction and sound suppression device for indoor low-frequency noise, which comprises a sound insulation top, which is composed of a plate body for sound absorption and sound insulation and a guide sheet for conducting vibration, and is fixed on the roof of a kitchen through bolts and through holes at four corners; at least one channel used for atomization is formed in each supporting stand column, the upper ends of the supporting stand columns are fixedly installed at the four corners of the bottom face of the sound insulation top, and liquid in the atomization channels can be atomized and output in combination with low-frequency vibration; through the arrangement of the sound insulation top and the supporting stand columns, low-frequency vibration noise conducted upstairs can be received and conducted, anti-phase sound waves are sent out according to vibration, active hedging elimination, absorption and isolation are conducted on low-frequency sound waves, and by means of the received low-frequency vibration, the noise reduction effect is achieved. The connecting rod is driven by vibration to drive the valve body to intermittently relieve blocking of the output end of the atomizing chamber in the designated space, atomized liquid medicine is discharged into a room, and the environment of the indoor space is humidified and improved through the liquid medicine.
本发明公开了一种针对屋内低频噪音的主动降噪抑声器，包括隔音顶，其由用于吸音隔音的板体和传导振动的导片组成，通过螺栓由四角位置的通孔固定在厨房的屋顶；和支撑立柱，其至少配置一根，且每根内部均开设有至少一个用于雾化的通路，上端固定安装在隔音顶底面的四角位置，可结合低频振动进行雾化通路内液体的雾化输出；本发明通过隔音顶和支撑立柱的设置，不仅可对楼上传导的低频振动噪音进行接收和传导，并根据振动发出反相声波，对低频声波进行主动的对冲消除以及吸收隔离，而且可利用接收的低频振动，振动驱动连接杆在指定空间内带动阀体间歇性解除对雾化室输出端的封堵，使雾化的药液排放至室内，利用药液湿化以及提升室内空间的环境。
