With his colleague Thomas Watson, Bell worked very hard on the experimentation to invent devices such as the harmonic telegraph ( used to send multiple messages over a single wire) and phonautograph ( used to draw the shape of the sound waves). The first telephone communication was said to have happened between Bell and Watson in 1876 while Bell was at one end of the line, and Watson worked on the telephone in other room.

The invention of the phonograph happened quite by accident . Thomas Edison moved to Menlo Park, New Jersy in 1876, where he established an industrial research laboratory . There, Edison was working on a carbon telephone transmitter to improve the exosting Bell telephone system
In that laboratory a year later, Edison invented the phonograph while he was trying to improve a telegraph repeater . He attached a telephone diaphragm to the needle in thetelegraph repeater ; in this way , he was able to reproduce a recording that could be played back. After he made some improvements to the machine, he tested it . He recited ‘‘Mary had a little lamb’’ into the machine and played his voice back to a very surprised audience
