About this title

Synopsis

Excerpt from Telephone Apparatus: An Introduction to the Development and Theory

The sound vibrations may consist of motions of the par ticles of a gas, such as air, or of a liquid or of a solid. By means of a telephone transmitter, the'sound vibrations may cause electrical vibrations which a telephone receiver at a distance will transform back into sound vibration, so that sound may be conducted indirectly by electricity.
