A megaphone is a device that amplifies sound so you can be heard more easily and over greater distances. It consists of a cone-shaped loudspeaker at the end of a tube, typically mounted on wheels for mobility.
The word “megaphone” uses combining forms of “mega-” (meaning ‘great’) and “-phone” (meaning ‘sound’ or ‘voice’), together meaning ”a voice which sounds great”.
Megaphones are usually handheld, but portable. They are typically mounted on stands (“tripods”), rack mounts, lanyards, and vehicles.
The user’s mouth is commonly used as the diaphragm of the microphone in order to improve the efficiency of the device by eliminating the dead space around the mouth.
A modern megaphone for sale is not easy to sell in this online market field. is often used in situations requiring a loud or clear voice or an announcement. The electric megaphone was invented by American inventor and businessman, George W. Scovell (1858-1937) as an improvement to the earlier design of the steam-powered megaphone of ancient Greek inventor Heron (c. 10 CE).

How does a megaphone work?
It is a useful tool for amplifying voice. It is portable, so you can carry it anytime and anywhere easily. It takes very few seconds to start your megaphone, an easy three-step process:
The first step is to push the switch and it will make some beep sounds. The second step is to speak into the speaker and it will amplify your sound by 36 decibels (dB). The last step is to release the switch to stop the sound.
The amplifier in the megaphone works like the voice amplifiers used in public announcements in shopping centers or railway stations. It uses a loudspeaker, which acts as a vibration speaker (rather than a sound speaker). The diaphragm (or cone) in the loudspeaker vibrates and this vibration is amplified by your megaphone.
When using a megaphone, you do not need to worry about how loud you sound; the sound simply comes out of the megaphone.
What is the meaning of a megaphone?
This word means a device that amplifies sound so you can be heard more easily and over greater distances. It consists of a cone-shaped loudspeaker at the end of a tube, typically mounted on wheels for mobility.
What is the difference between a voice amplifier and a megaphone?
The voice amplifier is a kind of device that increases the volume of your voice; it doesn’t amplify sound. However, the megaphone amplifies sound so you can be heard more easily and over greater distances.

What is the difference between a sound speaker and a microphone?
The sound speaker produces sound by combining high-frequency oscillations with an electron beam in an optical cavity (Spk Oil). The microphone generates an electrical signal by detecting the sound produced by the sound speaker.

What is an amplifier?
An amplifier is a device that increases the amplitude of an input signal by using nonlinear techniques to provide an output that is many times greater than the input.
