where can I buy megaphones or bullhorns in minneapolis
megaphones are a device that loud-ens sound to a distance.
It will make a loud noise.
Most megaphones are portable in the sense that the average person can carry them unassisted. However, there are other megaphones that have patented built in amplifiers that are also used with wireless or handsfree microphones enabling the user to wear them on their person as opposed to shouting through a typical bullhorn. These devices are lightweight and rechargable. http://www.uskoreahotlink.com/products/communications/portable_megaphone.php This is one example.
It was originally just a bunch of men with megaphones leading a crowd.

Megaphones work by capturing sound waves from a person's voice and then amplifying and directing those sound waves in a specific direction. The shape of the megaphone helps to focus the sound waves and make them louder and clearer for listeners.
The chemical formula for a megaphone does not exist, as megaphones are not composed of chemical elements but rather made of materials like plastic, metal, or wood. Megaphones are acoustic devices that amplify sound through the reflection and direction of the sound waves.
Megaphones amplify sound by directing and focusing sound waves through a cone-shaped structure. This helps to increase the volume of the sound. The shape of the megaphone also helps to project the sound over long distances by concentrating the sound waves in a specific direction, allowing them to travel further without losing intensity.
yes there is you can use most recording soft-wares to do it and also some voice recorders along with megaphones.
