"Practically the same, dad.  The wireless transmitter, like that of the wire telephone, contains a sensitive diaphragm which your voice strikes and sets to vibrating.  These vibrations compress and release a capsule of carbon granules which agitate and set in motion an electrical current in two magnets connecting with them.  The magnets convey the sound-waves in the form of electrical waves, along wires out to the tip of each wing, where the wires hang down a little way.  When a message comes in it is caught by a webbing of antennae wires in our wings."
