Speaker
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.
Sound energy and kinetic energy
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.
Chemical Energy (batteries); Electrical Energy; Sound and Heat Energy.
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.
Electrical Heat Light Sound Mechanical Kinetic
In a battery-operated radio, the chemical energy stored in the batteries is converted into electrical energy when the batteries supply power to the electronic components. The electrical energy is then converted into sound energy as the electronic components amplify and produce sound waves through the radio speaker.
When you turn on the TV, electrical energy from the outlet powers the TV, which converts it into light and sound energy to display images and produce sound. Heat energy is also released as a byproduct of the TV's operation.
In an electric fan electric energy is converted into mechanical energy which makes the blades of the fan spin. On the other hand in a loudspeaker electric energy is converted into sound energy which produces the music.
