Sound wave is essentially a pressure wave. What converts pressure wave to electricity is a piezoelectric element, basically a kind of vibrating membrane
Or arrange for the pressure vibrations to move a magnet within a coil, or move a coil over a magnet - the basis of all ancient microphones.

What is the energy change in an electric buzzer?
The energy change in an electric buzzer involves converting electrical energy to sound energy by causing a diaphragm or other vibrating element to produce sound waves, creating the buzzing sound. This process involves a transformation of energy from electrical to mechanical and acoustic forms.
How can electric energy change in sound energy?
Electric energy can be converted to sound energy through the use of a device such as a speaker. The electric current passing through the speaker's coil creates a magnetic field that interacts with a permanent magnet, causing the speaker cone to vibrate and produce sound waves. The variations in the electric current control the intensity and frequency of the sound produced.
Do sound waves carry electrical and magnetic energy?
No, sound waves do not carry electrical or magnetic energy. Sound waves are vibrations of particles in a medium, such as air, that propagate as mechanical waves through that medium. They do not involve the movement of electric charges or magnetic fields.
What waves transfer energy?
Electromagnetic waves, such as light and radio waves, transfer energy through oscillating electric and magnetic fields. In addition, mechanical waves, like sound waves, transfer energy through the vibration of particles in a medium.
What does a speaker convert electric energy into?
A speaker converts electric energy into mechanical energy to create sound waves. The electric signal from the audio source is amplified and sent through the speaker's coil, causing it to move back and forth rapidly. This motion vibrates the speaker cone, which then produces sound waves that we hear as audio.

Is it possible to convert sound waves to electrical energy?
Yes, it is possible to convert sound waves to electrical energy using devices called microphones or transducers. These devices can pick up sound vibrations and convert them into electrical signals that can be used to power various electronic devices.

No, sound waves do not carry electrical or magnetic energy. Sound waves are vibrations of particles in a medium, such as air, that propagate as mechanical waves through that medium. They do not involve the movement of electric charges or magnetic fields.
Why sound waves change into electromagnetic waves in telephone?
Because an electric signal is much easier to transfer over long distances than a sound is.

This motion vibrates the speaker cone, which then produces sound waves that we hear as audio.
Can heat energy change to sound energy?
Yes, heat energy can change into sound energy. When an object is heated, its molecules vibrate faster, creating thermal energy. If the object is a solid, these vibrations can produce sound waves that we hear as sound energy.
Earphones change electric current to sound waves?
That's a true statement. Now, what was your question ?
What causes energy waves?
Energy waves are caused by the vibration or disturbance of energy sources, such as sound waves resulting from vibrating objects or electromagnetic waves produced by accelerating electric charges. These waves carry energy through space by transferring the vibration or disturbance from one particle to another.
What type of energy does a guitar produce?
A guitar produces sound energy when the strings are strummed, causing vibrations that create sound waves. Additionally, when an electric guitar is plugged into an amplifier, it converts the sound energy into electrical energy to produce a louder sound.
What energy transfers take place in a speaker?
In a speaker, electrical energy is converted into mechanical energy through the electromagnet, causing the vibration of the speaker cone. This mechanical energy then produces sound waves that transfer energy in the form of sound waves through the air to our ears.
