A speaker is a device that transforms electrical signals into sound waves. The electrical current passing through the speaker's voice coil interacts with a magnetic field, causing the coil to move back and forth. This movement creates vibrations in the speaker cone, which in turn produces sound waves that travel through the air.
The device in a car that transfers electrical energy into sound energy is the car's speaker. The speaker receives electrical signals from the car's audio system and converts it into sound waves that we can hear.
An incandescent lightbulb is an example of a device that converts electrical energy into light and heat. A loudspeaker is a device that converts electrical energy into sound.
The human ear transfers sound energy, which is converted into electrical signals that are then processed by the brain to interpret and recognize as sound.
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.
In a toaster, electrical energy from the power source is converted to thermal energy through the heating elements. The thermal energy then transfers to the bread slices, causing them to heat up and toast.

In a microphone, energy transfers from sound waves in the environment to the diaphragm of the microphone. The diaphragm converts these sound waves into mechanical vibrations, which are then transformed into electrical signals by a transducer within the microphone. Finally, these electrical signals are transmitted to an amplifier or recording device for processing or storage.

An electronic motor transfers electrical energy to kinetic energy (movement energy). These use electromagnets, powered by your power source (eg. Batteries).
