Bell worked on the photophone, which transmitted sound on a beam of light. The device was a precursor of fibre optics.<br />
<br />
He worked on the phonograph and on the audiometer. He invented the metal detector and used it in an attempt to find a bullet in the body of President Garfield.<br />
<br />
He was interested in aviation and in the construction of kites and of hydrofoils. He founded the Aerial Experiment Association.<br />
