Megaphone

A megaphone is a handheld device used to amplify sound. It is typically cone-shaped, with a wide opening at one end and a narrow opening at the other. The wide end is held up to the speaker s mouth, while the narrow end projects the sound waves outward, making it louder and easier to hear over long distances. Megaphones are commonly used in various settings, such as sports events, protests, and emergency situations, where a clear and loud voice is needed to communicate with a large crowd. They are often made of durable materials like plastic or metal and may have additional features like adjustable volume controls or built-in microphones.
