The microphone icon on Roblox indicates that your microphone is currently active and that other players can hear you. If you want to turn off your microphone, you can do so by clicking on the microphone icon in the bottom left corner of the screen. This will mute your microphone and prevent other players from hearing you.
There are a few reasons why you might want to turn off your microphone on Roblox. For example, you may not want other players to hear you if you are in a public server and do not know anyone. You may also want to turn off your microphone if you are playing a game that does not require voice chat. Additionally, you may want to turn off your microphone if you are experiencing technical difficulties with your microphone.
