Be HEARD in any Crowd. This gadget is ideal for sporting events, picnics, boating, and calling the kids in for dinner. It has a 3 position switch, off/speak and a siren for emergencies. Volume control slide allows you to adjust projection without raising your voice. The megaphone is professional quality, projects 165 yards, weather resistant, and has a rugged hi-impact ABS construction.
An electronic megaphone amplifies sound to a higher decibel level. It consists of a microphone, an amplifier and a loudspeaker. A megaphone is a portable, usually hand-held, funnel-shaped device used to send a person’s natural voice toward a targeted direction. This is accomplished by channeling the sound through a funnel, which also serves to match the impedance of the voice cords to the air. The natural human voice tends to spread evenly in all directions, whereas when it is sent through a megaphone, the sound is concentrated in a given direction and the coupling of its energy to the air optimised. The trade-off is that if a listener is to the side, it is more difficult to hear what is being said.
