A microphone is a tool for doing just that.
However sound is an exceedingly poor source of energy, which is why amplfiers are used with microphones to boost the signal.
Electrical Energy

1) Sound already has energy, so if you have a sound, you don't need to convert anything. 2) If you strike an object, you'll make a sound - thus converting kinetic energy into sound energy.
They are a source of electrial energy because you have to charge them and people tend to chanrge them longer than needed suck as, overnight.
Acoustical energy is only the vibrations that make sound, so sound is another name.
Electrical Energy
Electrial energy
we used pawan chakki to transformed its electrial energy
heat energy is converted into electrial enegry when passed from magnetic energy
There may be an electrial shortage within the socket light or it may just need to be replaced.
True. Light is a form of electromagnetic energy.
It isn't "the best"; it is useful for some specific purposes.

Sound is energy. It is part of the electromagnetic spectrum.
Sound energy is mechanical energy. No devices are required to make a conversion.
That could be a power cell (battery), or more correctly, a capacitor.
