Dynamic magnetic pickup for stringed instruments
First Claim
1. A pickup for a stringed musical instrument, comprising:
- a primary coil magnetically coupled to a string of the musical instrument and fixedly attached to a string support structure;
a secondary coil magnetically coupled to the primary coil, the secondary coil further coupled to the primary coil by a flexible suspension mechanism.

Abstract
A pickup for use in a stringed musical instrument. The pickup includes a primary transducer that is sensitive to the motion of the musical instrument'"'"'s strings and is mechanically coupled to the body of the musical instrument. The primary transducer senses the motion of the musical instrument'"'"'s strings and generates a “string sound” signal in response. The primary transducer is further flexibly coupled to a secondary transducer that is not fixedly attached to the body of the musical instrument. Relative motion between the primary transducer and the secondary transducer generates a “body sound” signal within the secondary transducer. The string sound signal and the body sound signal are combined to generate a signal representing the acoustical response of the musical instrument.

10. A pickup for a stringed musical instrument, comprising:
-
a primary coil having a magnetic field for generation of a string signal in response to string movement;
a secondary coil electrically coupled to the primary coil in a noise cancellation circuit, the secondary coil flexibly coupled to a string support structure of the musical instrument and in the magnetic field of the primary coil whereby the secondary coil generates a string support structure signal in response to string support structure vibrations.

11. A pickup for a stringed musical instrument having a string support structure, comprising:
-
a primary coil, the primary coil having magnetic means for generation of a magnetic field in proximity to the string, the primary coil generating a string signal in response to movement of the string within the magnetic field; and
a secondary coil electrically coupled to the primary coil in a noise-cancellation circuit, the secondary coil suspended within the primary coil'"'"'s magnetic field by suspension means whereby the secondary coil vibrates within the magnetic field and generates a string support structure signal in response to vibrations of the string support structure. - View Dependent Claims (12, 13, 14, 15, 16)
