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.
Claims28
An audio transducer subassembly, comprising:
- a bobbin-shaped support structure subassembly having a flanged top, a base, and a core between the flanged top and base;
- and
- wherein the base is adapted to allow a pole piece to be positioned within the core and a magnet to be positioned inside the base in contact with the pole piece.
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.

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.
5 more elements
An audio transducer for a guitar, comprising:
- an electromagnetic array of individual audio transducers adapted to be mounted on a guitar, each transducer adapted to generate two analog string signals having opposite polarities for a single guitar string vibrating a predetermined distance from the audio transducer;
- and
- the array further including a noise transducer adapted to generate an analog noise signal representative of noise in the analog string signal pairs.
