What are the parts of a loudhailer?

A loudhailer, also known as a megaphone, typically consists of several key parts: a microphone to capture sound, an amplifier to increase the audio signal, and a horn or cone that focuses and projects the sound over a distance. It often includes a power source, such as batteries, and may have controls for volume and sound quality. Some models also feature additional components like a carrying handle and a strap for ease of use.
