The invention discloses a noise collection building vibrator. The noise collection building vibrator comprises a metal framework and a noise reduction device, wherein the metal framework comprises anupper metal framework and a lower metal framework, and the noise reduction device is located between the upper metal framework and the lower metal framework; the noise reduction device comprises a composite vibrating diaphragm, a first sound absorption layer and a gypsum layer which are sequentially arranged from top to bottom; the noise reduction device further comprises a sound collection sensorarranged on the upper surface of the composite vibrating diaphragm, a controller connected with the sound collection sensor, and an electric ceramic vibrating piece connected with the controller andattached to the lower surface of the composite vibrating diaphragm; and a plurality of protruding structures are arranged on the upper surface of the first sound absorption layer. The noise collectionbuilding vibrator is ingenious in structural design, remarkable in noise reduction effect, economical and practical.
本发明公开了一种噪音收集震楼器，包括金属骨架、降噪装置，所述金属骨架包括上金属骨架和下金属骨架，所述降噪装置位于所述上金属骨架和下金属骨架之间，所述降噪装置包括由上至下依次设置的复合振膜、第一吸音层、石膏层，所述降噪装置还包括设于所述复合振膜上表面的声音采集传感器、与所述声音采集传感器相连接的控制器、与所述控制器相连接并贴合所述复合振膜下表面设置的电动陶瓷震动片；所述第一吸音层的上表面设有若干凸起结构。本发明结构设计巧妙，降噪效果显著，经济实用。
