The loudspeaker (the cone-shaped bullhorn) means 'announcement' or 'listen up, everyone' — used to open a public message, marketing blast, or important update in a group chat. It's easily confused with 📣 megaphone, but loudspeaker is the classic hand-held cone shape often associated with formal notices rather than rallying crowds.
