The energy for a loudspeaker is audio-frequency electrical energy produced by an audio amplifier from low-level analogue electrical signals representing audio such as speech or music (and from a DC power supply).
The peak power for loud music in an average room is about 20 watts, while the average power is 0.2 watts or less.
Electrical energy is transferred into mechanical energy in a loudspeaker. The electrical signal from the audio source causes the speaker cone to move back and forth, creating sound waves that we hear as sound.

A loudspeaker is a transducer that converts electrical energy to sound energy.
A loudspeaker is a transducer; it converts one form of energy to another. In this case, electrical energy into acoustic (pressure) energy. Many types of loudspeaker can also be used as a microphone. This effect is known as reciprocity. An ordinary 'moving coil' loudspeaker will be quite a good microphone, when associated with appropriate amplifiers.
A loudspeaker converts electrical energy into mechanical energy to create sound waves. The electrical signal from the audio source is converted into variations in air pressure, which our ears perceive as sound.
A loudspeaker
In a loudspeaker, electrical energy is converted into mechanical energy to produce sound waves. In a microphone, sound waves cause a diaphragm to vibrate, converting the mechanical energy into electrical signals.
A loudspeaker converts electrical energy into mechanical energy (sound waves) and some heat energy. The majority of the input energy is transformed into sound, with a small portion dissipated as heat due to inefficiencies in the conversion process.
In a loudspeaker, electrical energy is converted into mechanical energy. The electrical signal from the audio source causes the speaker cone to move back and forth, generating sound waves. This transfer of energy results in the production of sound.
A loudspeaker changes electrical energy into sound energy by converting the electrical signal into vibrations that move the speaker cone and produce sound waves.
