The first working loudspeaker was invented by Alexander Graham Bell who incorporated the device into his other famous invention, the telephone. Bell was awarded the patent for the telephone in 1876 with the loudspeaker device included in the patent. However, the initial concept for the loudspeaker device was first developed in 1874 by a German inventor named Ernst W. Seimens.
