20W Public Address Megaphone 8-10 Hours Shoulder Strap
Public Address Megaphone Description
The loudness of a megaphone depends on the power output and design of the device, rather than the type of battery used. However, lithium battery megaphones are often more efficient and can provide longer battery life than other types of megaphones.
lithium battery megaphones have a USB port or auxiliary input that can be used to play music or other audio directly from a USB flash drive or external device such as a smartphone or MP3 player.
A public address megaphone, also known as a loudhailer or bullhorn, is a portable device used to amplify and project the voice of a speaker over a distance. It typically consists of a handheld microphone and a cone-shaped or horn-shaped speaker that amplifies and directs the sound in a specific direction.
