摘要： The present invention is a bridge truss that alleviates tensile and compressive stresses applied to an acoustic stringed instruments soundboard from the bridge. These tensile and compressive stresses are transferred through the bridge truss to chamber of the acoustic stringed instrument instead. The bridge truss allows the support brace of the acoustic stringed instrument to be reduced or eliminated. The bridge truss provides the soundboard with the ability to produce longer sustained vibrations, and vibrations of greater amplitude—increasing performance and tone. Also, the relative height of the soundboard can be altered for greater playability, at a user's discretion. A user only needs to reposition threaded adjustment rods from atop the bridge of the acoustic stringed instrument in order to transfer more or less stress to the bridge truss.

摘要： A reverse bridge tension configuration for a stringed instrument allows the stringed instrument to offset some of the tension felt by the bridge. For a typical stringed instrument such as a guitar, the tensioned strings are bound between the bridge and the headstock. However, the reverse bridge tension configuration loops the tensioned strings on a path that goes around the back of the instrument, through the body of the instrument, and back to the bridge. A reverse bridge is positioned on the corner of the soundboard and the back end so that the tensioned strings can loop around the back end without causing pressure damage to the outer surface of the instrument. Once the tensioned strings travel around the reverse bridge and into the body, channels are positioned within the body in order to guide the tensioned strings back to the bridge.
摘要翻译： 用于弦乐器的反向桥梁张力配置允许弦乐器抵消桥梁感觉到的一些张力。 对于诸如吉他的典型的弦乐器，张紧的绳子被绑在桥和头架之间。 然而，反向桥梁张力配置将张紧的绳索环绕在仪器背面的路径上，通过仪器的主体，并返回到桥梁。 反向桥被定位在音板和后端的拐角处，使得张紧的绳可围绕后端环绕，而不会对仪器的外表面造成压力损坏。 一旦张紧的绳子围绕反向桥梁行进并进入主体，则通道被定位在主体内，以将张紧的绳索引回到桥梁。

摘要： A reverse-pull and double-down pressure bridge configuration for a stringed instrument is used to integrate a set of retrofit strings into the instrument. The retrofit strings are tethered between the bridge plate of the instrument and the back end of the instrument so that the retrofit strings are able to apply a reverse pull on a soundboard of the instrument and compress the saddle, the bridge, and the soundboard of the instrument. The retrofit strings are configured to counteract the forward pull applied on the soundboard by the original strings of the instrument.
