A megaphone is a device used to amplify sound over a distance. It typically consists of a cone-shaped device attached to a handle or strap, with a built-in microphone and amplifier. Megaphones are commonly used in sporting events, political rallies, and other large gatherings to project the speaker’s voice to a wider audience.
There are several different types of megaphones available, including battery-powered portable models and larger, more powerful models that can be mounted on tripods or stands. Some models also come with additional features like sirens, recording capabilities, and the ability to play music or pre-recorded messages.
Overall, megaphones are an effective way to communicate over long distances and are commonly used in a variety of settings where amplification is necessary.
