For vocal and far-reaching transmission of the spoken word, the mouthpiece was first developed in the 17th century by inventors and scientists, such as. For example, the Englishman „Samuel Morland,“ who invented the „Speech Trumpet“ in 1670 or the French priest and inventor „Laurent Cassegrain,“ who gave the funnel-shaped mouthpiece an optimized hyperbolic shape. The term „megaphone“ appeared for the first time in the 19th century in connection with the inventor Thomas Edison, who developed in 1878 a device that was similar to the mouthpiece in its function. With the mouthpiece of Edison a soft whisper could be heard at a distance of a thousand yards, while a normal voice could be heard at about three kilometers. However, Edison’s mouthpiece was extremely large. In the 1960s, the electric variant increasingly replaced the previously used acoustic mouthpiece.

Accordingly, the megaphones are also equipped for this output. As a rule, the volume of mobile megaphones is variably adjustable in different stages. Likewise, the open electrical mouthpieces differ in wattage, depending on the model z. B. can range from 10 watts to 80 watts. In addition to the volume of megaphones above all the range plays a crucial role. Depending on the performance of the model, the range may be a few hundred meters or even two kilometers.
