The metal part which makes up the bell.
clapper
its when you pluck it
Sound vibrates the bell (the part at the end), that vibrate the column of air in the tubing, this vibrate the earpiece and recreates the sound.
Well, it's not necessary for the whole object to vibrate, but the part of it that's producing the sound does. Example: I'm not vibrating when I produce sound, but my vocal chords are, otherwise there's no sound. So the answer to what you're trying to ask is: No.
We just learned about this in science class. Air vibrates throughout the tube part and out the bell to produce sound waves.
Most percussion and string instruments operate of vibrations to produce sound. Drum heads, xylophone bars, strings and reeds all vibrate on instruments that use them to produce sound.
Vocal cords, located in the larynx or voice box, are the main part of the human body that produce sound for speech and singing. Air passing through the vocal cords causes them to vibrate, producing sound waves that create sound.
The part of the bell that makes the sound is called the clapper. This is the hanging piece inside the bell that strikes its sides to create the ringing sound.
Glottis are vocal folds that vibrate, which produces a "zzz" sound. This sound is a voiced sound that is part of speech.
An electric bell is basically a metal dome that vibrates when struck by a small hammer. An electromagnet is used to make the hammer strike the bell, moving the hammer back and forth very quickly.
The Trumpet its self doesn't vibrate, its the vibrations of your buzz that makes the sound. As you buzz on the mouth piece, the vibrations go through the horn to the valves. When it reaches the valves, according to the ones you have pressed down, it has to take different routs to get to the bell (This along with your lips, changes the note).
This is a matter of discussion. Your lips are used to set up a sinusoidal pressure wave in the trumpet, but nothing in the trumpet tubing vibrates to produce the sound. Modern testing shows that the pressure forms into "standing waves" which produce the sound when they hit the bell area where the standing waves are amplified to reproduce the pressure waves again.
A piano produces sound just like a guitar. Inside piano either grand or upright has piano strings attached inside with every keys. When you hit a certain key, the strings vibrate creating sound that is very pleasing in the ear.
