A megaphone, also known as a portable loudspeaker, is a handheld voice amplification device used to project clear, powerful sound over long distances for announcements, crowd control, and emergency communication.
Megaphones are portable public address (PA) devices designed to amplify speech and recorded audio in indoor and outdoor environments. They typically feature a built-in microphone, adjustable volume control, siren or alarm function, and rechargeable or battery-powered operation. Many models also include voice recording, USB, SD card, or Bluetooth playback for pre-recorded messages and music. Their lightweight construction and ergonomic handle make them easy to carry and operate.
