Cell Phone, Shock

It is usually depicted as: on the orange background picture, there is a mobile phone with several lines distributed on both sides. The shapes of lines vary from platform to platform, mainly including curved lines, outward straight lines, arcs and wavy lines. It is worth noting that some platforms depict a heart-shaped shape on or next to the mobile phone, which is white or pink; There are also some platforms that design a bell pattern next to the mobile phone, which also adds a red forbidden symbol. In addition, unlike most platform icons, the lines are distributed on the left and right sides of the mobile phone; In the Microsoft platform, the lines are only distributed on the right side of the mobile phone.
The emoji can be used not only to indicate that you don't want to trouble others in the library or subway, but also to remind others to keep quiet.
