The voice from a person's mouth (air flow) vibrates a diaphram which translates the vibrations (mechanical energy) into electrical wave oscillations using an magnet and a coil. These electrical oscillations are superimposed on to a high frequency carrier wave and sent over physical wires, under sea cables, micro wave towers, satellites etc (purely electrical energy) and at the receiving end the carrier wave is removed and only the wave that was generated by the voice and hence the diaphram and hence the magnet and the coil is made to drive a coil over which is a diaphram which vibrates (mechanical energy) to reproduce the sound. Of late digital phones have come into the market but the basic principle is the same. Convert mechanical energy to electrical energy and then convert electrical energy to mechanical energy.
What else can I help you with?
What are the main energy changes in a loudspeaker and microphone?
In a loudspeaker, electrical energy is converted into mechanical energy to produce sound waves. In a microphone, sound waves cause a diaphragm to vibrate, converting the mechanical energy into electrical signals.
What are energy transformation in a telephone?
The telephone system converts acoustic energy into electric energy
Which energy flows in telephone?
Electrical energy
What is the energy source of the telephone?
the telephone wire it is connected 2
How does energy conversion make a telephone a useful machine?
The conversion of energy from one form to another helps let the telephone have all the energy it needs to work.
What kind of energy does a telephone change your voice into?
electrical energy.
What energy is transferred by speaking into a telephone?
Sound energy is transferred when speaking into a telephone. The vibrations caused by the sound of our voice are converted into electrical signals that are then transmitted through the telephone line to the receiving end.
Sound energy examples?
When telephone is ringing
What changes chemical energy to energy?
The mitochondria changes food energy to chemical energy.
What changes mechanical energy to energy?
A generator changes mechanical energy into electrical energy.
Defined as a device that changes sound into electric current?
The telephone does that!
What energy conversion of telephone?
A telephone converts electrical energy into sound energy. When you speak into the telephone, your voice is converted into an electrical signal that travels through the phone lines. At the recipient's end, the electrical signal is converted back into sound waves, allowing the listener to hear your voice.
