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)
What else can I help you with?
Can you convert sound energy into another form of energy?
Yes, sound energy can be converted into other forms of energy such as electrical energy using devices like microphones that convert sound waves into electrical signals. These electrical signals can then be used to power various electronic devices or systems.
What are the devices used to convert sound energy to electric energy?
The devices used to convert sound energy to electric energy are called microphones. Microphones capture sound waves and convert them into electrical signals, which can then be amplified, recorded, or processed by electronic devices.
How do you make electrial energy from sound energy?
Sound energy can be converted to electrical energy using a device called a piezoelectric transducer. When sound waves interact with the transducer, it generates an electric charge that can be captured and stored as electrical energy. This process is often used in applications such as microphones and energy harvesting from ambient noise.
Can you change the sound waves into electric energy?
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.
How can electrical energy change into sound energy?
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

How electrical energy is converted into sound energy?
Electrical energy is converted into sound energy through a process involving an electrical signal passing through a transducer, such as a speaker or a buzzer. The electrical signal causes the transducer to vibrate, which in turn creates sound waves that we perceive as sound. This conversion process allows us to hear the audio produced by devices like speakers, headphones, and microphones.
How do microphones detect sound?
Microphones detect sound by converting acoustic waves into electrical signals. This is usually accomplished by a diaphragm that moves in response to sound waves, which then causes a coil or capacitor to generate an electrical signal corresponding to the sound received.
What does a loudspeaker change electrical energy into?
A loudspeaker changes electrical energy into sound energy by converting the electrical signal into vibrations that move the speaker cone and produce sound waves.
Which piece of apparatus would you use to change sound energy into electrical energy?
A microphone is a device that converts sound energy into electrical energy. Sound waves cause a diaphragm in the microphone to vibrate, which in turn generates an electrical signal that represents the sound.
How does microphones work?
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.
