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 mechanical energy. No devices are required to make a conversion.

Fireworks convert chemical energy into light and sound energy.
Light and sound
If the household items work with electricity, they will convert electrical energy to whatever they are supposed to do: movement for some devices, sound or light for others.

The energy transformation during fireworks show are, fireworks convert chemical energy into light and sound energy.
Converts Electrical energy into the useful energy, light and sound. There will be some unwanted heat energy as well
sound 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.
All energy converters will give out heat. Tv's will get energy from their source and convert it to sound, light and heat energy.
