The most common way is with a magnet and a coil of wire. Have either the magnet or the coil (it doesn't matter which) fixed in place and the other one attached to a membrane that will vibrate with the sound. When a magnet moves past a coil of wire, it causes an electric current in the wire.

What changes a sound wave into an electric current?
Sound waves are longitudinal waves. These would vibrate a diaphragm which has been attached with a coil kept in a magnetic field. As the coil vibrates then current is induced. This is how sound wave gets changed into electric current.
Does the ear drum have an electric current?
Actually your eardrum does not have electric current and in which it only uses sound so if you get an electric shock it does not harm your ear drums.
Defined as a device that changes sound into electric current?
The telephone does that!
Can an electric current produce sound?
Yes, an electric current can produce sound when passing through a material that vibrates in response to the flow of electrons. This vibration creates sound waves that can be heard. Examples include speakers and buzzers.
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.
Does increased current flow change the sound of an electric buzzer?
yes
How sound is produced from electric current?
Sound is produced from electric current when the current flows through a transducer, such as a speaker or buzzer, which converts the electrical energy into mechanical vibrations. These vibrations create changes in air pressure, which our ears detect as sound waves. By controlling the frequency and intensity of the current, different sounds can be produced.
How electric energy is change to sound energy?
Electric energy is converted to sound energy in devices such as speakers and headphones. When an electric current passes through a coil of wire in the device, it creates a magnetic field that interacts with a permanent magnet, causing the coil to move back and forth. This movement of the coil creates vibrations in the air, which are interpreted by our ears as sound.
How does sound travel through a microphone?
Sound waves enter the microphone and are then converted to an analog electric current.
What forms of energy can electric current be converted into?
Electric current can be converted into various forms of energy, including heat in resistive elements, light in incandescent bulbs or LEDs, motion in electric motors, and sound in speakers. Additionally, electric current can also be used to produce magnetic fields in electromagnets.
What makes the pickup guitar make sound?
A guitar pickup is wire coiled around a magnet. When the string vibrates, it causes the magnet to vibrate, which creates an electric current in the wire. The signal created by that electric current is then fed into the amplifier which converts it to sound.
Does electric current cause a coil wired to become an electric bell?
Yes, when an electric current flows through a coil wired to an electric bell, it creates a magnetic field. This magnetic field causes the coil to move and strike a bell, producing a sound.
