Electromagnetic transducer for instrument pickups

摘要: This invention relates generally to electromagnetic transducers, and more specifically, devices that convert the mechanical vibrations of a magnetically permeable object, such as ferromagnetic instrument string, into an electrical signal using electromagnetism. In one embodiment, includes core, core being susceptible, including opposing ends are in close proximity each other define gap, gap configurable receive portion at least string susceptible; magnet, magnet disposed proximate transfer magnetic flux from transferable through ends; coil, coil about produce current response wherein vibration produces induces coil.
