The more familiar megaphones were invented around 1650.
Megaphones have gone through many transformations since its invention. They have acoustic visions, which are the megaphones used alone.The acoustical versions follow the ancient Greece megaphone technology. There are also electrical megaphones that have a built-in electronic amplifier. Megaphones that are electrified can alter a voice, play music or even use a siren sound.
