The invention is applicable to the technical field of daily necessities, and provides a soundproof curtain and a control method thereof. The curtain comprises a curtain frame with grooves around it, with strip-shaped electromagnets being fixed in the lower groove and grooves at two sides, and being connected to a power supply through a relay; a reel fixed to the upper groove, with one end of the reel being fixedly connected to the output shaft of a motor through a pulling wire; a curtain sloth the upper end of which is fixedly connected to the reel and the lower end and left and right ends ofwhich are respectively provided with magnetic strips, the two sides being respectively clamped in the grooves on the left and right sides of the curtain frame, and the bottom of the magnetic strips onthe lower end of the curtain being provided with a piezoelectric thin film sensor; a noise sensor located on the outside of the curtain frame; and a controller connected in communication with noise sensor, the motor, piezoelectric film sensors and relays. If the noise in the environment is greater than the noise upper limit threshold, the curtain is controlled to move downward, and when the curtain moves downward to the bottom, the electromagnets in the grooves is energized, thereby attracting the magnetic strips on the curtain, so that the curtain is seamlessly connected with the curtain frame, thereby achieving the purpose of reducing noise.
Description
technical field [0001] The invention belongs to the technical field of daily necessities and provides a soundproof curtain and a control method thereof. Background technique [0002] With the development of industry, the noise pollution in the environment is becoming more and more severe, especially for residents living near roads or railways. Most of the existing sound insulation curtains are made of sound insulation materials, and the noise is reduced by sound insulation materials. , but because there is a large gap between the curtain and the window frame, the noise can be transmitted through the gap between the curtain and the window frame, and there is a problem that the sound insulation effect is not ideal. Contents of the invention [0003] An embodiment of the present invention provides a soundproof curtain, aiming at the large gap between the existing curtain and the window frame, noise can be transmitted through the gap between the curtain and the window frame, a...
