well there are kind of 4 but the main one is sound energy.
But there is also kinetic as the speakers move,there is heat energy as the plug would get hot and there is light energy as of the lights on the speaker!!!
input is eLeCtRiCaL eNeRgY
sound energy
When electricity runs through

output
Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power, mainly electricity. Tidal energy is a renewable energy source.
It means to convert the energy to a form that is useful for humans - for making machines work, for example. Or simply, convert to a form of energy that is easily converted to other forms of energy, for example, AC electricity, at an appropriate voltage.

Solar Energy
Virtually all forms and types of energy are useful in some way or another.

The relationship between input work and useful output work can be represented by efficiency. Efficiency is the ratio of useful output work to input work. A higher efficiency indicates that a larger proportion of the input work is converted into useful output work, while a lower efficiency suggests that more of the input work is wasted or converted into non-useful forms.
Energy always turns from useful energy to less useful forms of energy. so in theory the answer is no, but in reality there is always some heat generated in all transformations.
it forms when electricty runs through a curcit through two wires
cogeneration
Yes,burning fuel is a useful chemical reaction as energy is released and can be converted into different forms to do useful work
in, electromagnetic radiation in the form of sunlightout, chemical energy in the forms of sugars, starches, celluloses, etc.
Conversions of energy forms are lossy. For example, when mechanical energy is converted to electrical energy (such as happens in an electric generator), there is friction which leads to the escape of heat and sound energy. While the total amount of energy in all forms remains constant, the heat and sound energy are next to impossible to recapture, so this is considered a loss of useful energy.
Energy Resource, sounds like a definition of a fuel
