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.

10. An audio transducer, comprising:
-
a magnetic assembly having only two magnetic pole pieces and adapted to generate two magnetic fields;
a coil assembly positioned within the magnetic fields and adapted to generate two signals when the magnetic fields are varied by a guitar string vibrating in the magnetic fields;
a support structure adapted to provide support for the coil and magnetic assemblies; and
wherein 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 (11, 12, 13, 14, 15, 16, 17)

18. An audio transducer, comprising:
-
a magnetic assembly adapted to generate two magnetic fields;
a coil assembly positioned within the magnetic fields and adapted to generate 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 adapted to provide support for 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 (19, 20, 21, 22)
