A sound amplifier.
While electronic amplifiers will amplify sound (we do this all the time), there are also mechanical devices that "direct" the sound and make it sound louder. They don't actually create more than is there, but they can be effective. A megaphone does the trick. Lastly, there are situations where sound can stimulate things mechanically and cause those things to resonate. This will create more mechanical energy than was there originally, and the sound will have been amplified.The ear drum slightly ampliflies the sound... By amplifying it, it focuse's it futhermore so that the brain can prossess the sound. In between those two phases many other steps occur, but that's the ear drum's role.
The ear has a timpanic membrane called the eardrum. This vibration is transferred to the anvil and stirrup bones in the ear that send a signal through the hearing nerves.
resonator
it amplifies the sound actually, by strengthening the waves. the sound waves are converted into equivalent electrical waves and then it amplifies and later those electrical waves are converted the sound waves . the principle of electromagnetic induction is applied here.
...frequency of sound is equal to the eigenfrequency (which depends on the shape of the guitar).

A resonator.
They are acoustic, inside is a diaphram that vibrates and amplifies sound passing it through the hollow tubes.
A resonator.
First the strings then the rest of it amplifies it.
A microphone and an amplifier with a loudspeaker does this. The microphone converts the soundpressure to electric signals. The amplifier amplifies these signals and the loudspeaker converts back the electric signals to sound pressure. Our ear drums are moved by the sound pressure as a sound field quantity. It is not the sound intensity as an energy quantity.
Yes a guitar amplifies sound although an acoustic sounds more than electric guitar but they all resonate sound
