Definition

A funnel-shaped device used to amplify and direct sound, allowing a person's voice to project over long distances to a large audience. Modern versions often use electronic amplification rather than purely acoustic amplification.

Example Usage

The protest organizer used a megaphone to address the crowd of thousands gathered in the plaza.

Origin

From Greek 'megas' (great) + 'phone' (sound or voice).

Fun Fact

The acoustic megaphone works by funneling sound waves in one direction, using the geometry of the cone to amplify without electricity—a principle that predates electronic amplification by centuries.
