What is used to convert sounds from your voice into radio signals?

Answer 1

The conversion of sound waves in to radio is done by a device called transmitter.Many devices such as radio and mobile device are equipped with receiver antenna and speaker to convert back radio waves in to sound waves.

Answer 2

Technically, the sounds aren't "converted". Various electronic devices are used to detect the sounds,

and to impress information onto a radio signal from which similar sounds can be created.

A microphone is used to create an electrical current that varies according to variations in the sounds.

A modulated oscillator or modulated amplifier then uses the varying electrical current from the

microphone to change either the amplitude or frequency of another alternating current, which is

then used to create radio waves.

All of these gadgets together in one package are commonly referred to as a radio "transmitter".

Answer 3

The equipment at the radio station converts sound coming through a microphone into electric signals which are amplified to make it stronger, then converted (modulated) into higher (broadcasting) frequencies and sent to an antenna where it is broadcast as electromagnetic radiation.
