Xerox machines do not convert light energy into sound.
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.

Sound energy is actually a mechanical energy.

Fireworks convert chemical energy into light and sound energy.

current signal into light energy
There is no direct sound-light transducer but you could connect a microphone and amplifier to a suitable l.e.d. driving circuit.
IT is formed into sound,heat,light,wind and mechanical energy.
A neon lamp.
