Sound box for floor-standing string instrument

摘要

A sound box for floor-standing string instrument includes a resonance box being provided on a top surface with at least one recess for receiving a spike below the string instrument therein, and an opening extended through the top surface of the resonance box; and a pad attached to a bottom surface of the resonance box. The resonance box and the pad together form a sound reflection controlling mechanism, so that vibration waves transmitted from the string instrument to the sound box are reflected back to the string instrument. The reflected sound waves combine with the original vibration waves to amplify the sound produced by the string instrument, making the sound more brilliant and sweeter.
