The megaphone or speaking Trumpet was claimed to have been invented by both Samuel Morland and Athanasius Kircher somewhere between 1635 and 1655. Thomas Edison was the first to be associated with the word "megaphone" in 1878 when he developed a device which he hoped would benefit the deaf and hard of hearing.
