How was the telegraph different from the telephone?
The electromagnet that drives the telegraph’s stylus is no different in principle from the electromagnet found in an audio speaker. The only difference is that the audio speaker’s magnet switches on and off much faster — thousands of times a second — causing the speaker membrane to vibrate, producing a sound.
