  • Suspended bracing system for acoustic musical instruments
    Patent number: 7446247
    Abstract: A suspended bracing system is disclosed that allows the sound board of an acoustic instrument, such as a guitar, to vibrate more. As a result, the instrument projects more tone and volume than that provided by conventional guitar sound boards. Conventional sound boards have wood or synthetic bracing glued all across the sound board. This is to prevent the bridge from pulling up when the strings are tightened to pitch. Using the suspended system, the invention disclosed herein secures the bridge, but drops the bracing below the sound board of the guitar to allow the sound board more freedom to vibrate.
