A crystal receiver will pick up radio signals within a close range. One must use headphones to hear the signal, as it is generally very weak. A crystal receiver does this without the use of electricity or batteries.

Did Tesla invent the crystal radio?

A crystal radio receiver, also called a crystal set, is a very simple radio receiver, popular in the early days of radio. It needs no battery or power source and runs on the power received from radio waves by a long wire antenna. Crystal radios are the simplest type of radio receiver, and can be handmade with a few inexpensive parts, like an antenna wire and tuning coil of copper wire. Tesla invented the coil and that was the basis of it but at the turn of the 20th century, an American scientist, Greenleaf Whittier Pickard, found that a number of naturally occurring crystalline minerals could be used to detect radio signals.


Was the crystal radio the first radio invented?

It was certainly the first kind of radio receiver to become popular with the average person during radio's formative years, although whether it is what all the inventors used is doubtful. We do know that in the first several years of commercial broadcasting (1920-22), if you wanted a radio receiver, you generally had to build your own. The crystal detector was the easiest set to build, and it received a signal fairly well. Crystal sets became very popular in that era before tubes, and before there were a lot of stations on the air. Crystal sets were not sophisticated, but they got the job done until something better came along.
