发明名称 Magnetized frets for a stringed musical instrument
摘要 The present invention is concerned with providing a fret for a stringed musical instrument having strings containing ferromagnetic material, wherein the fret is arranged to be magnetic. Having a downward magnetic force exerted on the strings by a fret ensures full and consistent contact between a string and the fret when the string is pressed down against the fret. The invention has three embodiments that describe different ways of providing magnetism to the fret. In a first embodiment the fret is comprised of magnetic material. In a second embodiment a magnet is coupled to the fret to supply magnetic properties to the fret. In a third embodiment an electromagnetic coil is wrapped around a portion of the fret in order to induce magnetism.
