Definition & Meaning of "soundbox"

What is a "soundbox"?

A soundbox is the hollow part of a musical instrument that amplifies and projects the sound. It is found in instruments such as guitars, violins, and cellos. When the instrument is played, the vibrations from the strings or other sound-producing parts travel into the soundbox. The shape and size of the soundbox affect how the sound is amplified and how it resonates, contributing to the instrument's overall tone and volume.
