We heard the sound of the electric curtain is often not the voice of the rotation of the motor, but the motor rotates and drives the transmission parts inside the orbit of a series of switch or action, resonance curtain track and curtain box voice. If the electric curtain is installed on the top surface of the cement material, the sound of the resonance is small. But usually after the renovation of the curtain box is a large core material, the resonance of the sound to be larger.
Each brand is different, but generally around 35 dB, should be considered relatively small. Like the United States, such as the creation of the international brand of electric curtains and ultra quiet, the motor itself, like the noise of a beep sound, the sound is very small, but the relative weight of the smaller.
At the same time, to a small voice, can choose mute and ball tooth belt quality, so it is the traditional pass or the steel wire transmission rail noise better.
Select the mute motor sounds will not be great, now many brands have a mute motor, have their own advantages, Chengdu Belinda would do in this respect or want to be good. The electric curtain operation noise is mainly because of the friction between the ball and the belt and gear box and track produced the second is the voice track now mostly uses the high quality Aluminum Alloy manufacturing, between the curtain box and orbital resonance also must produce certain sounds.
