Bell's interest in telephony sparked the idea of inventing the telephone. While working on a harmonic telegraph, a reed stuck on the transmitter that was converted to a continuous current. The sound heard on the receiver confirmed Bell's belief that sound could be transmitted and reconverted through an electric wire with the use of continuous electric current.
