Abstract
A novel multi-signal guitar pickup is provided. The pickup includes a coil assembly for each string that is capable of generating two signals which can be combined together in a predetermined manner to generate an x-plane and a y-plane signal. The pickup is particularly useful in a digital guitar system which generates multiple digital signals representative of the vibrations of each string.

9. An audio transducer, comprising:
-
a magnetic assembly having only two magnetic pole pieces for generating two magnetic fields; a coil assembly positioned within the magnetic fields for generating two signals when the magnetic fields are varied by a guitar string vibrating in the magnetic fields; a support structure supporting the coil and the magnetic assemblies; and wherein the two signals generated by the coil assembly are combined together in a predetermined manner to generate an x-plane signal representative of vibrations of the guitar string in a first plane a predetermined distance from and parallel to an upper surface defined on the support structure and a y-plane signal representative of vibrations of the guitar string in a second plane a predetermined distance from the magnetic pole pieces and perpendicular to the upper surface of the support structure. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An audio transducer, comprising:
-
a magnetic assembly for generating two magnetic fields; a coil assembly positioned within the magnetic fields so that the coil assembly generates two signals when the magnetic fields are varied by a guitar string vibrating in the magnetic fields; a support structure having two support structure subassemblies supporting the coil and magnetic assemblies; and wherein the bobbin shaped support structures are held in position with respect to one another by magnetic forces generated by the magnetic assembly; and the two signals generated by the coil assembly can be combined together in a predetermined manner to generate an x-plane signal representative of vibrations of the guitar string in a first plane a predetermined distance from and parallel to an upper surface defined on the support structure and a y-plane signal representative of vibrations of the guitar string in a second plane a predetermined distance from the magnetic pole pieces and perpendicular to the upper surface of the support structure. - View Dependent Claims (18, 19, 20, 21)
