摘要： A humbucker pickup device for active and passive guitars including a matched pair of elongated coil assemblies with two sets of ferromagnetic pole pieces also includes two elongated, transversely polarized permanent magnets positioned between and parallel to the coils. The magnets are beside each other with opposite poles facing each other. The magnets with two respective pole pieces under each string establish two narrow magnetic fields to interact with the string at two points and a weaker intermediate magnetic field between the said pole pieces. The humbucker device includes an improved differential amplifier built from two or three operational amplifiers. Alternatively, the device may include a steel plate between the magnets for further weakening the intermediate magnetic field. Both embodiments, with and without the plate, are described.

摘要： Electromagnetic transducers suitable for a variety of uses, including but not limited to musical instrument pickups. Such a transducer has a primary loop formed by an electrically conductive strip having oppositely-disposed ends and a slot extending therebetween that defines electrically conductive runners. The strip is bent to define a first section of the primary loop that overlies a second section of the primary loop and a gap therebetween. The transducer further comprises sensing or driving elements that are at least partially received in the slot in the first section of the primary loop and a transformer electrically connected to the strip at one of the ends thereof opposite the first section of the primary loop.

摘要： An electromagnetic pickup for electric guitars has one or two dual-coil assemblies wherein an inner coil is wound around a bobbin and then an outer coil around the inner coil. In the dual-coil assembly the inner coil replaces the entire or part of wall space of pole piece holes in a plastic molded bobbin. The outer and inner coils in the dual-coil assembly are electrically connected in-phase to produce single coil pickup sound. The outer coil is connected to the coil in the other pole piece/bobbin/coil assembly out-of-phase to generate humbucking pickup sound.

The pickup also includes an elongated main permanent magnet having a length L such that L>S and an elongated ferromagnetic shell having a length at least as great as S. The main permanent magnet, the pickup coil, and the shell are assembled together in an electromagnetic pickup assembly in which at least one side of the pickup coil is enclosed by the shell, and the main permanent magnet is parallel to the central opening of the coil; the assembly generates a magnetic field which encompasses at least one portion of the pickup coil. A housing mounts the pickup assembly on the musical instrument with the top of the coil facing the instrument strings, which intercept a portion of the magnetic field.

摘要： A magnetic pickup for a stringed musical instrument has one or more composite ferromagnetic pole pieces. The composite pole pieces have two or more components with different ferromagnetic materials properties in fixed and contiguous positions. The tonal properties of the pickup are partially determined by the materials and arrangement of the components and are variable over a wide parameter space. Pickups with composite pole pieces and methods for reconfiguring pickup with monolithic pole pieces are described.
