Magnets and an electrical current;
the analog signal is converted into sound via the diaphragm
Tubular bells create sound when struck with a mallet. The impact causes the metal tubes to vibrate, producing a clear and resonant tone. The length and thickness of the tubes determine the pitch of the sound created.
In a buzzer, electrical energy is transformed into sound energy. The electrical energy powers the electromagnet that causes a metal arm to vibrate rapidly, creating sound waves.
When a source of energy causes a medium to vibrate, it creates sound waves. Sound waves are mechanical waves that travel through a medium by causing the particles of the medium to vibrate and transfer energy in the form of sound.
Mechanical Waves
An object that produces sound when air causes it to vibrate is called a sound source. This vibration creates pressure waves in the air, which we perceive as sound when they reach our ears. Examples of sound sources include musical instruments, vocal cords, and speakers.
Small electrical currents are sent to usually plastic disc shaped similar to uor ear drum. These currents vibrate the disk causing sound to be produced.

Movement causes the air to vibrate. This creates sound waves.

Both guitars and pianos have strings. Striking the strings causes them to vibrate, which makes the sound that you hear.
An object that produces sound when air causes it to vibrate is called a sound source. This vibration creates pressure waves in the air, which we perceive as sound when they reach our ears. Examples of sound sources include musical instruments, vocal cords, and speakers.
The sound of a gong is produced when the broad, flat surface of the gong is struck with a mallet or drumstick. The impact causes the metal to vibrate, creating a rich and resonant sound that can be heard both near and far.
Sound energy causes the eardrum to vibrate. Sound waves travel through the air and when they reach the eardrum, the vibrations are converted into electrical signals that are sent to the brain for interpretation.
