Battery Powered Megaphone Description
A lithium battery megaphone is a type of megaphone that uses a lithium-ion battery as its power source. Lithium-ion batteries are commonly used in electronic devices due to their high energy density, low self-discharge rate, and long cycle life.
Battery-powered megaphones typically feature a handheld microphone, a volume control knob, and a built-in speaker, which amplifies the user's voice and broadcasts it over a distance. Some models may also include additional features such as a siren function, an auxiliary input for playing music, or a recording function for storing and playing back messages.
