Fabricated acoustic metamaterial and sound barrier plate
The invention discloses an assembly type acoustic metamaterial and a sound baffle. The assembly type acoustic metamaterial comprises a mounting seat arranged on a wall body and a vibration reduction unit detachably arranged in the mounting seat. The vibration reduction unit comprises a mounting frame of a circular ring structure, a composite film is arranged on the surface of one side of the mounting frame, one end of the composite film penetrates through the mounting frame in a surrounding mode and then is connected with multiple sets of connecting blocks in an annular array, and the connecting blocks are movably connected with one ends of first connecting rods. The other end of the first connecting rod is connected with a connecting ring located at the circle center position. By arranging the screw rod, the connecting ring and the driving sleeve are driven to move in the axial direction of the screw rod under the action of the motor, finally, the connecting block is linked to move, the connecting block is connected with the edge end of the composite film, and finally, the tensioning degree of the composite film is adjusted through the movement of the connecting block; and the frequency of the composite film can be dynamically adjusted in real time according to the field noise condition, and the sound absorption and insulation effects of the whole device are greatly improved.
本发明公开了一种装配式声学超构体及声障板，包括设置在墙体上的安装座和可拆卸设置在安装座内的减振单元；其中：所述减振单元包括圆环结构的安装架，所述安装架一侧表面上设置有复合膜，且复合膜的一端环绕穿过安装架之后与多组呈环形阵列的连接块连接，所述连接块活动连接第一连接杆一端，所述第一连接杆另一端连接位于圆心位置的连接环。本发明通过设置螺杆，在电机的作用下驱动连接环和驱动套沿螺杆轴向方向运动，最终联动连接块运动，由于连接块与复合膜边端连接，最终通过连接块的运动调节复合膜的张紧程度，使得复合膜能够根据现场噪音情况进行实时的频率动态调节，极大的提高了整个装置的吸引隔音的效果。
