Акустичні рупори застосовують головним чином у рупорних гучномовцях. Рупори, яким підсилюють голос, називаються мегафоном. Електродинамічні рупори використовують як опромінювачі і як самостійні антени переважно для приймання і передавання сантиметрових і міліметрових радіохвиль.


Переносно  — провідник, виразник чиїхось ідей, думок, настроїв тощо.
