Abstract
The pickup system for a string instrument uses a combination of a single under-string pickup, or a primary pickup, and a secondary offset pickup that is placed away from the strings. The primary pickup senses the vibrations of the strings while also picking up background noise. The secondary pickup does not pick up the vibration of the strings, only picking up the background or environmental noise. Thus, in various combinations, the secondary pickup with the primary pickup can cancel out the background noise. This cancellation occurs without creating any drag beyond that of the primary pickup.
Claims20
A pickup system for a stringed instrument comprising:
- a primary pickup;
- the primary pickup located under one or more strings;
- the primary pickup senses vibration of the one or more strings;
- the primary pickup creates a primary signal;
- a secondary pickup;
- the secondary pickup is offset from the primary pickup, placed away from the one or more strings;
- the secondary pickup does not sense vibration of the one or more strings;
- the secondary pickup creates a secondary signal;
- the primary pickup is wired in series or parallel with respect to the secondary pickup;
- whereby a combination of the primary signal and the secondary signal removes environmental electromagnetic noise from an output signal.
A pickup system for a stringed musical instrument, comprising:
- a first pickup transducer configured to sense vibrations from one or more strings of the stringed musical instrument and convert the vibrations into a first electrical signal;
- a second pickup transducer placed separately from the first pickup transducer in an orientation that does not detect vibrations from the one or more strings, the second pickup transducer configured to convert ambient electromagnetic noise into a second electrical signal;
- wherein the first pickup transducer and the second pickup transducer are electrically connected, allowing the second electrical signal to subtract ambient electromagnetic noise from the first electrical signal;
- thereby producing an output signal containing string vibration components with reduced electromagnetic noise.
A system for sensing vibrations of strings of a stringed instrument, while removing environmental noise, comprising:
- a primary pickup and a secondary pickup;
- the primary pickup located under the strings of the stringed instrument;
- the primary pickup sensing vibrations of the strings and sensing environmental noise;
- the primary pickup outputting a primary electrical signal;
- the primary pickup able to be placed at a multiplicity of positions under the strings of the stringed instrument;
- the secondary pickup not located under the strings of the stringed instrument;
- the secondary pickup sensing only environmental noise;
- the secondary pickup outputting a secondary electrical signal;
- a positive rail and a negative rail;
- the primary pickup moving along the positive rail and the negative rail;
- the positive rail and the negative rail carrying the primary electrical signal of the primary pickup, regardless of position of the primary pickup;
- wherein the primary pickup and the secondary pickup wired in series or parallel, a combination of which cancels out environmental noise.
