Abstract

The present invention is a pickup system including a transducer, a mount, and a cartridge for modifying perceived sound from a musical instrument. The transducer includes a housing, a magnet and an electric signal carrier. The mount attaches the transducer to the instrument. The cartridge includes a container and attachment device, which positions the container in proximity to the transducer. The attachment device engages the container with the transducer so as to affect the electric signal created by the instrument. The cartridges and container can be either integral or interchangeable to vary resonance materials to the transducer. The container may be filled with another material, including ferromagnetic fluid for an induced magnet effect upon the perceived sound from the transducer.

Dependent claims

A pickup system for detecting and converting sound and vibrations from a musical instrument into an electric signal for amplification, broadcasting, and recording, wherein the instrument is comprised of an instrument body, the pickup system comprising:

a transducer means comprised of a housing, a magnet and an electric signal carrier, said transducer means having a magnetic field;
a mounting means attached to said transducer means;
and
a cartridge means being comprised of a container and an attachment means and being positioned in proximity to said transducer means, said attachment means engaging said container with said transducer means,
wherein said container is comprised of a first material, and wherein said container is filled with a second material, said first material and said second material being different from each other, each material affecting the electric signal and having resonant effects,
wherein said second material is a fluid, and wherein said container houses said fluid, and
wherein said fluid is ferromagnetic, said fluid creating an induced magnetic field complementary to the transducer means, wherein said transducer means is positioned at a distance from said cartridge means so that said induced magnetic field of said cartridge means is complementary to said magnetic field of said transducer means.
