Teh varying pressure of the air (the sound) causes a varying electric potential in microphones. There are various techniques, one is called "dynamic microphone" whereby a membrane with a coil is allowed to move inside a magnetic field. The sound moves the membrane, the movement of the coil inside the magnetic field generates a current in the wire which is the signal.
Ten kinds of microphone are discussed on Wikipedia (see Related link below)
Microphone is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal.
Example: piezo electric transducer.

A microphone converts sound waves into an electronic signal.
To change sound energy into electrical energy you need to use a transducer, which changes sound into electrical impulses.
Electrical - mechanical - sound. From electrical energy, electricity is passed unto an amplifier, a microphone or a cdplayer is connected to the amplifier. The amplifier then change the sound entering it into mechanical energy. Then sound is passed out through a speaker cable givin sound energy
Sound - vibrations in the air.
SOUND
A microphone is a device that converts acoustical pressure waves (or sound, which is mechanical energy) into electrical energy or signals. All microphones have a diaphragm, membrane, or other mechanical element in them that vibrates sympathetically in response to the arriving acoustic wave fronts. This mechanical element acts on the electrical element to generate electromagnetic energy (voltage). The actual mechanism used to make the conversion from mechanical energy to electrical energy will vary from mic to mic. Let's examine one kind.We see some microphones that have a diaphragm with a coil of wire attached to that diaphragm. Inside the coil is a stationary magnet. The sound energy moves the diaphragm, which moves the coil (with the stationary magnet inside it). The movement of the coil in the fixed magnetic field generates an electrical signal in the coil that "corresponds" to the sound that created it. The signal may then be sent via wires to an amplifier. There are other types of microphones, and for information on them, follow the link below.
does electrical energy can change into sound? yes it can
To change sound energy into electrical energy you need to use a transducer, which changes sound into electrical impulses.
Electrical - mechanical - sound. From electrical energy, electricity is passed unto an amplifier, a microphone or a cdplayer is connected to the amplifier. The amplifier then change the sound entering it into mechanical energy. Then sound is passed out through a speaker cable givin sound energy
With a microphone
the technology is used in microphones but in reverse. instead of the wires creating the sound and the cone amplifying it, the cone gets your sound and the wires turn it into electrical energy.
Electrical energy -> Sound energy.
Electrical energy -> Heat energy -> Sound energy.
Microphones will convert sound waves into electrical signals. An ear (i..e human ear) will also convert sound waves into electrical signals.

Sound is collected by microphones, which are devices that convert sound waves into electrical signals that can be processed, stored, and reproduced. Microphones can come in various types, such as dynamic, condenser, and ribbon microphones, each with its own characteristics suited for different applications.
