Some people call them sonic transducers or tone-arm cartridges,
but they're most often and most commonly called microphones.
laser microphone
We can convert electrical energy into mechanical energy in mixer and grinder. We can convert electrical energy into sound energy in various sound systems. We can convert electrical energy into heat energy in electric water or room heater.
Electrical energy is converted to sound energy in loudspeakers and earphones. The basic internal transducers are either magnetic coils or piezo-electric crystals.
Lots of devices do that. A motor will convert electrical energy to mechanical energy (i.e., to movement); a lamp will convert it to light; a speaker will turn it to sound; etc.
In electric bell, electrical energy is converted int sound energy.
Sound energy is mechanical energy. No devices are required to make a conversion.

heat(useful energy) and sound(waste energy)
We can convert electrical energy into mechanical energy in mixer and grinder. We can convert electrical energy into sound energy in various sound systems. We can convert electrical energy into heat energy in electric water or room heater.
Not likely - any machine wastes some energy; that would reduce the useful output energy.

sound energy
we can convert sound waves to electric waves and by giving supply we can generate sounds to Piezo electric crystals or ceramics. The process of converting sound waves to electric waves with the help of peizo electric crystals is called peizo electric effect
Xerox machines do not convert light energy into sound.
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.
