2. (figurative) Something that helps a person spread their message widely. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/megaphone/#m2)

### In the lessons

In everyday life, megaphones are used at sports days, protests, beaches, fire drills and on boats. In science, a simple cone megaphone directs sound waves forward, so the voice carries further. Safety: never shout into someone's ear with a megaphone, because very loud sound can damage hearing. Phrases: «speak through a megaphone», «megaphone diplomacy» (shouting messages publicly rather than talking).
