Sound waves are not converted into radio waves. First sound waves are changed into electrical signal using a microphone. Then this mild signal is amplified. Now a high frequency radio wave is modulated with this amplified signal. This modulated radio wave is then propagated through space.
In most devices, including headphones, earphones, radios, televisions and computers, electrical energy is transformed to sound energy by an electrodynamic loudspeaker. A speaker consists of a coil of wire suspended in a magnetic field. Changes in the current in the wire cause motion of the coil--the same principle of conversion of electrical to mechanical energy first demonstrated by Michael Faraday in 1821. The electrodynamic loudspeaker is actually a specialized form of electric motor. Like other electric motors, an electrodynamic loudspeaker can be also used in reverse--as a generator--to transform sound energy into electrical energy.
Electrical - Sound energy?
It used the electrical energy to amplify the radio signal. - that is an electromagnetic wave.
electrical to sound (and light as well, but only for the tv unless your radio lights up when plugged in) :)
It converts electrical energy to mechanical energy. The speaker vibrates in response to an electrical signal.
It would be eletrical to sound energy
electrical energy
through sound energy
In an electric fan electrical energy is transformed into mechanical energy and in loudspeaker the electrical energy is converted into sound energy.
an example of thermal energy being transformed into sound energy is the crackling of a fire
The main energy-changes are as follows: Chemical (in the battery) to electrical Electrical to sound
The potential energy is transformed into kinetic energy, heat and sometimes sound.

A radio receiver transforms electrical energy to acoustic energy
In an electric fan electrical energy is transformed into mechanical energy and in loudspeaker the electrical energy is converted into sound energy.
Energy transformed by the means of energy transformation.

A radio produces sound, and therefore sound energy. The radio waves, however, are electromagnetic energy, not sound. The function of a radio is to convert that electromagnetic energy into sound energy.

In a radio you have the conversion of radio wave energy to sound wave energy.
