I’ll be explaining why stringed instruments are provided with a sound box.

Of course we’re talking about that area where the strings overlap a hole located usually in the middle of the instrument.

You’ll see this on acoustic guitars, ukeleles, violins and many other related sounds.

Let’s move on to the question.

Why are stringed instruments provided with a sound box

To create a vibration sound within the inside of the instrument.

This phenomena amplifies the literal volume of anything played when plucking the strings.

Yes, this area of the instrument closes the distance between the face of the board and air itself.

The vibration sound

This area behind the strings is the hollow box that traps the sound produced when you pluck the strings of the instrument.

what happens to the vibration of a string when it’s plucked

The string vibrates a pure tone that bounces after contact with each sound sounding different from the next.

The science of vibrations and how they work would suggest that if you plucked the string of an instrument that the sound would stick depending on where you’re at.

Someone asked a question on Reddit that got a response mentioning how a vibration would survive if plucked in space.

It’s even supported with a smaller example in which motion is energy that wants to move until it’s completely stopped.

In the case of the vibration feeling you experience it withers away in the force produced because it dissipates until all energy is used.

Conclusion

That should be good enough information that explains what the hollow box inside any stringed instrument does.

It vibrates the entire core of the instrument it’s done on, adjusts the volume produced to a louder and crisper sound.

Also, it closes the distance between the instrument and air as a whole.
