First the strings then the rest of it amplifies it.
We just learned about this in science class. Air vibrates throughout the tube part and out the bell to produce sound waves.
The strings are the source for vibrations but the whole instrument vibrates to some extent when they are sounded.
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.
Nearly every part vibrates, or should vibrate depending on the quality of your instrument. The vibration passes from the string to the bridge to the face and then through to the sides and back of your instrument. Most of the sound you hear comes from the face and back of the instrument. That is why electric instruments such as electric violins and electric guitars are so quiet; their bodies are not designed to absorb the vibrations from the strings. struck, hit, scraped
In a stringed musical instrument, the part that vibrates in resonance with the sound waves produced by the strings is called the soundboard or the resonating body. This part amplifies and projects the sound created by the vibrating strings to produce audible music.

The eardrum
We just learned about this in science class. Air vibrates throughout the tube part and out the bell to produce sound waves.
Musical instruments have some part that vibrates at a regular frequency. This vibrating part makes the air around it vibrate and these vibrations make the sound waves. The part that vibrates is often a string or a reed or a drum-head or in the case of horns, the player's lips. The vibrations are amplified by a column of air or a sounding board or something else that resonates at the frequency produced by the original vibration.
The reed of the shehnai, which is placed inside the mouthpiece, is the part that vibrates when air is blown into the instrument. The vibration of the reed creates the sound that is characteristic of the shehnai.
The middle ear, consisting of the three tiny bones called the ossicles (malleus, incus, stapes), amplifies vibrations from incoming sound waves before transmitting them to the inner ear.
The strings are the source for vibrations but the whole instrument vibrates to some extent when they are sounded.
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.
In a radio, it is the speaker that vibrates to create sound. The electrical signals from the radio's circuitry are converted into physical vibrations by the speaker's diaphragm, producing audible sound waves.
The sound waves come through the auditory canal and hit the eardrum (or tympanic membrane). The eardrum is connected to the 3 ossicles of the middle ear: the hammer, anvil and stirrup (or malleus, incus and stapes). The eardrum vibrates the hammer, the hammer vibrates the anvil, the anvil vibrates the stirrup and the stirrup vibrates the cochlea in the inner ear which has hair-like nerve endings called cilia that move when the cochlea vibrates. The auditory nerve sends the vibrations to the brain to be interpreted. That's how we hear! :)
