I am not sure if it was a badge or not that Jiminy had. I thought it might be like a portable megaphone. You know how in Ep 1 when he was talking at the war counsel Jiminy was speaking into a megaphone. Then in Ep 4 where we learn about Jiminy’s episode when he becomes a cricket he is chirping to the Blue Fairy and their are subtitles. So i think we are supposed to believe that if Jiminy speaks through a megaphone or something like that his chirps are translated into English. So i think the thing that Jiminy was wearing was some sort of portable megaphone. I would need to get a closer look, but that was my thought.
